Title: Email Translation Method and Electronic Device

Description:
TECHNICAL FIELD 
     This application relates to the field of terminal technologies, and in particular, to an email translation method and an electronic device. 
     BACKGROUND 
     As functions of electronic devices become more powerful, an increasing quantity of users use applications installed on electronic devices, such as mobile phones or tablet computers, for mobile officing. As an application for mobile officing, email can be used to provide information exchange services for users. 
     However, in the prior art, when a sender needs to translate email content written in an email writing area, the sender needs to select to-be-translated content, enable translation software to translate the to-be-translated content, select a translation result, and copy the translation result into the email writing area. This operation manner for copying the translation result into the email writing area is relatively complex. 
     SUMMARY 
     Embodiments of this application provide an email translation method and an electronic device, to simplify an operation manner for copying a translation result into an email writing area. 
     According to a first aspect, an embodiment of this application provides an email translation method, including: 
     displaying a first user interface, where the first user interface includes an email writing area, and the email writing area includes content written by a user; in response to a translation operation of the user on the written content, adding a first email translation area to the first user interface, where the first email translation area includes a first result preview area and a function bar, the first result preview area includes a translation result of the content written by the user, and the function bar includes a replacement button; and in response to an operation of the user on the replacement button, replacing the content written by the user included in the email writing area with the translation result, and displaying the translation result. 
     In this embodiment of this application, the content written by the user included in the email writing area can be replaced with the translation result by operating the replacement button. This simplifies an operation manner and improves operation efficiency. 
     It should be noted that the operation on the replacement button may be a tapping operation on the replacement button, a touch and hold operation on the replacement button, a hard press operation on the replacement button, or the like.

In addition, the applications supported by the electronic device may further include a plurality of other applications, for example, drawing, a game, a phone, a video player, a music player, photo management, a camera, a browser, a calendar, a clock, and the like. 
     For example,  FIG. 1  is a schematic diagram of a possible hardware structure of an electronic device. It should be understood that the hardware structure of the electronic device  100  shown in the figure is merely an example. In addition, the electronic device  100  may have more or fewer components than those shown in the figure, may combine two or more components, or may have different component configurations. Components shown in the figure may be implemented on hardware, software, or a combination of hardware and software that includes one or more signal processing and/or application-specific integrated circuits. 
     The electronic device  100  may include one or more processors  101 , a memory  102 , a radio frequency (radio frequency, RF) circuit  103 , an audio circuit  140 , a speaker  141 , a microphone  142 , a touchscreen  150 , one or more sensors  106 , a wireless fidelity (wireless fidelity, Wi-Fi) apparatus  107 , a peripheral interface  108 , and a power supply apparatus  109 . These components may perform communication by using one or more communications wires (for example, buses). A person skilled in the art may understand that, the hardware structure shown in  FIG. 1  does not constitute a limitation on the electronic device  100 , and the electronic device  100  may include more or fewer components than those shown in the figure, or some components may be combined, or a different component deployment may be used. 
     The following describes each component of the electronic device  100  in detail. 
     The processor  101  is a control center of the electronic device  100 , and is connected to each part of the electronic device  100  by using various interfaces and lines. The processor  101  performs various functions of the electronic device  100  and processes data by running or executing an application (application, APP) stored in the memory  102 , and invoking data and an instruction that are stored in the memory  102 . For example, the processor  101  may translate an email body or an email subject into a target language. 
     In some embodiments, the processor  101  may include one or more processing units. Alternatively, an application processor and a modem processor may be integrated into the processor  101 . The application processor mainly processes an operating system, a user interface, an application, and the like, and the modem processor mainly processes wireless communication. It may be understood that, alternatively, the modem processor may not be integrated into the processor  101 . For example, the processor  101  may be a Kirin 970 chip. In some other embodiments of this application, the processor  101  may further include a fingerprint verification chip, configured to verify a collected fingerprint. 
     The memory  102  may be configured to store an application, data, and various operating systems, such as iOS, Android®, Microsoft, or another operating system. The memory  102  mainly includes a program storage area and a data storage area. The program storage area may store an operating system, and an application required by at least one function (for example, a sound playing function, or an image playing function). The data storage area may store data created when the electronic device  100  is used, for example, a photo or a video taken by a user by using the electronic device  100 , or audio recorded by the user by using the electronic device  100 . The data storage area may further store a file such as a picture downloaded by the user, an email written by the user by using the electronic device  100 , an email received by the electronic device  100 , or the like. In addition, the memory  102  may include a nonvolatile memory, such as a magnetic disk storage device or a flash memory device. It may be understood that the application may be stored in a memory. The data, such as the photo, the video, or the email, may be stored in another memory. 
     The RF circuit  103  may be configured to receive and send a radio signal in an information receiving/sending process or a call process. Specifically, the RF circuit  103  may send downlink data received from a base station to the processor  101  for processing. In addition, the RF circuit  103  may further send uplink data to the base station. Generally, the RF circuit  103  includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier, a duplexer, and the like. In addition, the RF circuit  103  may further communicate with another device through wireless communication. The wireless communication may use any communication standard or protocol, including but not limited to a global system for mobile communications, a general packet radio service, code division multiple access, wideband code division multiple access, long term evolution, an email, a short message service, and the like. 
     The audio circuit  140 , the speaker  141 , and the microphone  142  may provide an audio interface between the user and the electronic device  100 . The audio circuit  140  may convert received audio data into an electrical signal and then transmit the electrical signal to the speaker  141 , and the speaker  141  converts the electrical signal into a sound signal for output. In addition, the microphone  142  may convert a collected sound signal into an electrical signal. The audio circuit  140  receives the electrical signal and converts the electrical signal into audio data, and then outputs the audio data to the RF circuit  103  to send the audio data to, for example, a mobile phone, or stores the audio data to the memory  102  for further processing. 
     The touchscreen  150  may include a touch-sensitive surface  151  and a display  152 . The touch-sensitive surface  151  (for example, a touch panel) may collect a touch event performed by the user of the electronic device  100  on or near the touch-sensitive surface  151  (for example, an operation performed by the user on the touch-sensitive surface  151  or near the touch-sensitive surface  151  by using any suitable object such as a finger or a stylus), and send collected touch information to another component such as the processor  101 . The touch event performed by the user near the touch-sensitive surface  151  may be referred to as a floating touch. The floating touch may mean that the user does not need to directly touch a touchpad for selecting, moving, or dragging a target (for example, an App icon), and the user only needs to be near the electronic device to perform a desired function. In an application scenario of the floating touch, terms such as “touch” and “contact” do not imply a direct contact with the touchscreen  150 , but a contact near or close to the touchscreen  150 . The touch-sensitive surface  151  on which the floating touch can be performed may be implemented in a capacitive type, an infrared light sensing type, an ultrasonic wave type, or the like. 
     The touch-sensitive surface  151  may include two parts: a touch detection apparatus and a touch controller. The touch detection apparatus detects a touch direction and position of the user, detects a signal brought by the touch operation, and transmits the signal to the touch controller. The touch controller receives touch information from the touch detection apparatus, converts the touch information into touch point coordinates, and then sends the touch point coordinates to the processor  101 . The touch controller may further receive an instruction sent by the processor  101 , and execute the instruction. In addition, the touch-sensitive surface  151  may be implemented in a plurality of types such as a resistive type, a capacitive type, an infrared type, and a surface acoustic wave type. 
     The display (also referred to as a display screen)  152  may be configured to display information that is entered by the user or information provided to the user, and various menus of the electronic device  100 . For example, the display in this embodiment of this application may be an LCD (liquid crystal display, liquid crystal display) or an organic light-emitting diode (organic light-emitting diode, OLED). For example, an active-matrix organic light emitting diode (active matrix organic light emitting diode, AMOLED) may be used. 
     It should be understood that the touch-sensitive surface  151  may cover the display  152 . After detecting a touch event on or near the touch-sensitive surface  151 , the touch-sensitive surface  151  transmits the touch event to the processor  101  to determine a type of the touch event, and then the processor  101  may provide corresponding visual output on the display  152  based on the type of the touch event. Although in  FIG. 1 , the touch-sensitive surface  151  and the display  152  are used as two independent components to implement input and output functions of the electronic device  100 , in some embodiments, the touch-sensitive surface  151  and the display  152  may be integrated to implement the input and output functions of the electronic device  100 . It may be understood that the touchscreen  150  is formed by stacking a plurality of layers of materials. In this embodiment of this application, only the touch-sensitive surface (layer) and the display (layer) are presented, and other layers are not described in detail in this embodiment of this application. In addition, in some other embodiments of this application, the touch-sensitive surface  151  may cover the display  152 , and the size of the touch-sensitive surface  151  may be greater than the size of the display  152 , so that the display  152  is entirely covered by the touch-sensitive surface  151 . Alternatively, the touch-sensitive surface  151  may be disposed on a front side of the electronic device  100  in a full panel form, in other words, any touch performed by the user on the front side of the electronic device  100  can be sensed by the electronic device. In this way, full touch experience on the front side of the electronic device can be implemented. In some other embodiments, the touch-sensitive surface  151  is disposed on a front side of the electronic device  100  in a full panel form, and the display  152  may also be disposed on the front side of the electronic device  100  in a full panel form. In this way, a bezel-less structure can be implemented on the front side of the electronic device. In some other embodiments of this application, the touchscreen  150  may further include a series of pressure sensor arrays, so that the electronic device can sense pressure exerted on the touchscreen  150  by the touch event. 
     The one or more sensors  106  may be a light sensor, a motion sensor, or another sensor. Specifically, the light sensor may include an ambient light sensor and an optical proximity sensor. The ambient light sensor may adjust luminance of the display  152  based on intensity of ambient light. When a user answers a call by using the electronic device  100 , the user moves the electronic device  100  to an ear. If the optical proximity sensor detects that the electronic device  100  is close to the ear, the optical proximity sensor may notify the processor  101  of an event that the electronic device  100  is close to the ear, and the processor  101  controls the display  152  to turn from bright to dark. As one type of motion sensor, an accelerometer sensor may detect a value of acceleration in each direction (generally, three axes), may detect a value and a direction of gravity of the electronic device  100 , and may be applied to an application for identifying a posture (for example, screen switching between a landscape mode and a portrait mode, a related game, and magnetometer posture calibration) of the electronic device, a function related to vibration recognition (for example, a pedometer, or a knock), and the like. 
     In some embodiments of this application, the sensor  106  may further include a fingerprint sensor.

The navigation bar  202  may include a back button  205 , a home button  206 , and a menu button  207 . In some embodiments, the back button may also be referred to as a return button or a backward button; the home button may also be referred to as a main screen button; and a menu button may also be referred to as a historical task viewing button. In addition, it can be understood that in some other embodiments, the status bar  201  may further include a Bluetooth icon, a Wi-Fi icon, an icon of an external device, and the like. It can also be understood that in some other embodiments, the home screen shown in  FIG. 2  may further include a dock bar. The dock bar may include icons of common applications and the like. After the electronic device  100  detects a touch operation of a user finger (or a stylus or the like) on an icon of an application, in response to the touch operation, the electronic device  100  starts the application, and displays a user interface of the application on the touchscreen  150 . For example, if detecting a touch operation on the email icon  204 , the electronic device  100  displays a user interface of email on the touchscreen  150  in response to the touch operation. For example, the user interface of email may be a user interface  300  shown in  FIG. 3 . The user interface  300  of email may include a navigation bar  301 , an email list  302 , and a function bar  303 . For example, the function bar  303  includes a button used for searching the email list  302  for an email, a button used for refreshing the email list  302 , a button used for filtering an email in the email list  302 , and a button used for displaying a user interface for writing a new email. It can be understood that a quantity and functions of buttons included in the function bar  303  are not limited in this embodiment of this application. It can be understood that the button included in the function bar  303  may be a virtual button or may be a physical button. This is not limited in this embodiment of this application. 
     In some other embodiments, the electronic device  100  may include a home screen button  208 , as shown in  FIG. 2 . The home screen button  208  may be a physical key or may be a virtual key. The home screen button  208  is configured to return from a user interface displayed on the touchscreen  150  to the home screen based on a user operation. This can be convenient for a user to view the home screen at any time and perform an operation on a control (for example, an icon) on the home screen. The operation may specifically be pressing the home screen button  208  by the user. In some other embodiments of this application, the home screen button  208  may further be integrated with a fingerprint sensor, so that when a user presses the home screen button  208 , the electronic device  100  can perform fingerprint collection and confirm an identity of the user. In some other embodiments, the electronic device  100  may alternatively not include a home screen button  208 . 
     For simplification of a user operation during translation of content of an email, in this embodiment of this application, a suspend button may be added to a user interface for writing an email or viewing an email, so that the electronic device  100  can display a translation result of the email in response to an operation on the suspend button. This simplifies a user operation and further improves user officing efficiency. 
     The user interface for writing an email may be a user interface for replying to a received email, may be a user interface for writing a new email, may be a user interface for email forwarding, or the like. The user interface for viewing an email may be a user interface for viewing a received email, may be a user interface for viewing a sent email, may be a user interface for viewing an email in a draft box, or the like. For example, the electronic device  100  may display a suspend button on the user interface for viewing an email, in response to an operation of displaying the user interface for viewing an email. In this way, when a user is unfamiliar with a language used for an email displayed on the touchscreen  150 , the user can translate, by performing an operation on the suspend button (for example, a touch operation on the suspend button), the email into a language with which the user is familiar (for example, a system setting language). This is conducive to improving email viewing efficiency of the user. For another example, the electronic device  100  may display a suspend button on the user interface for writing an email, in response to an operation of displaying the user interface for writing an email. In this way, after a user has written a to-be-sent email by using a familiar language on the user interface for writing an email, for ease of viewing the email by a recipient, the user can translate, by performing an operation on the suspend button, the written email into a language familiar to the recipient and then send the email to the recipient. This is conducive to improving writing efficiency of the sender, and improving viewing efficiency of the recipient. 
     The following uses a user interface for viewing a received email as an example for detailed description. 
     The electronic device  100  may display the user interface  300  shown in  FIG. 3  on the touchscreen  150 . The user interface  300  includes the email list  302 . Then, the electronic device  100  detects a touch operation on an area  304  included in the email list  302 , where the area  304  includes at least one of a sender Peter, an email subject “Welcome to our company”, and partial email body content. As shown in  FIG. 3 , an email in the email list  302  may be displayed in the area  304 . In response to the touch operation on the area  304 , the electronic device  100  displays, on the touchscreen  150 , a user interface illustrating email content details about an email with the email subject “Welcome to our company” sent by the sender Peter. The following uses an example for detailed description in which the user interface illustrating email content details is a user interface  400  shown in  FIG. 4A . As shown in  FIG. 4A , the user interface  400  includes an email preview area  404  and a suspend button  401 , and the email preview area  404  includes email body content; and if detecting an operation on the suspend button  401 , the electronic device  100  adds an email translation area to the user interface  400  in response to the operation on the suspend button  401 , where the email translation area includes a result preview area, and the result preview area includes a translation result of the email body content. For example, a user interface after the email translation area is added to the user interface  400  may be shown as a user interface  410  in  FIG. 4B . Using the user interface  410  as an example, the user interface  410  includes an email preview area  404  and an email translation area  411 , where the email translation area  411  includes a result preview area  412 , and the result preview area  412  includes a translation result of email body content. In addition, in some embodiments, for ease of viewing content in the email preview area  404  on the user interface  410  by a user, the content may be viewed by sliding up and down within the email preview area  404 . For ease of learning about viewing progress by the user, a progress bar  413  may be added to the email preview area  404 , so that the user can learn about a location, in the entire email body content, of email body content currently displayed in the email preview area  404 . Similarly, for ease of viewing a translation result in the result preview area  412  on the user interface  410  by the user, the translation result may be viewed by sliding up and down within the result preview area  412 . For ease of learning about viewing progress by the user, a progress bar  414  may be added to the result preview area  412 , so that the user can learn about a location, in the translation result of the entire email body content, of a translation result currently displayed in the result preview area  412 . Moreover, it should be noted that the suspend button  401  may be displayed on the user interface  410 , or the suspend button  401  may be hidden. This is not limited. 
     It can be understood that, the operation on the suspend button  401  may be a touch operation on the suspend button  401  (for example, tapping the suspend button or double-tapping the suspend button), a touch and hold operation on the suspend button  401 , a hard press operation on the suspend button  401 , or the like. This is not limited. It should be noted that the user interface shown in  FIG. 4A  is an example of the user interface for viewing a received email in this embodiment of this application. 
     In some other embodiments, a location of the suspend button  401  is movable. For example, if a user finger presses and holds the suspend button  401 , the suspend button  401  can move following a motion trail of the user finger. In addition, as shown in  FIG. 4A , the user interface  400  may further include a function bar  402 , a button  403  used for returning to a previous-level menu, a sender, a recipient, an email subject, email body, and the like. For example, the function bar  402  may include a button used for email reply, a button used for email forwarding, and a button used for email deletion. It can be understood that the function bar  402  may alternatively include at least one of a button used for email reply, a button used for email forwarding, and a button used for email deletion. In some other embodiments, the function bar  402  may further include a button used for email collection, and the like. A quantity and functions of buttons included in the function bar  402  are not limited in this embodiment of this application. 
     The following describes a case in which the electronic device  100  adds the email translation area  411  to the user interface  400  in response to the operation on the suspend button  401 . The email translation area  411  includes the result preview area  412 , and the result preview area  412  includes the translation result of the email body content. It should be noted that in some embodiments, the user may perform editing, cutting, copying, and the like on the translation result included in the result preview area  412 . 
     In some embodiments, a language of the translation result may be a system language. For example, if the system language is simplified Chinese and a language of the email body content is English, the language of the translation result is simplified Chinese. For another example, if the system language is English and a language of the email body content is Japanese, the language of the translation result is English. It should be noted that the system language in this embodiment of this application may be set by using a system setting screen. For example, a system setting screen  520  shown in  FIG. 5C , and the electronic device  100  may display the system setting screen  520  on the touchscreen  150  in the following manners. The electronic device  100  may display a system setting screen  510  on the touchscreen  150 , in response to a touch operation on a setting icon  501  included in the user interface  500  shown in  FIG. 5A . The system setting screen  510  may include a button  511  used for language and region settings. In some other embodiments, the system setting screen  510  may further include a button used for account login, a button used for enabling cloud backup, a button used for screen locking, a button used for wireless and network settings, a button used for applications and notifications, and the like. A quantity and functions of buttons included in the system setting screen  510  are not limited. The electronic device  100  may display the system setting screen  520  on the touchscreen  150  in response to a touch operation on the button  511  used for language and region settings. The system setting screen  520  includes a button  521  used for system language setting. In some other embodiments, the electronic device  100  may alternatively display the system setting screen  520  on the touchscreen  150 , in response to a quick operation of the user. A manner in which the electronic device  100  displays the system setting screen  520  on the touchscreen  150  is not limited in this embodiment of this application. The electronic device  100  may display, on the touchscreen  150 , a language list  531  supported by the electronic device  100 , in response to an operation on the button  521  (for example, tapping “system language”). The user may select a corresponding language from the language list  531  to set the system language. In some other embodiments, the user may alternatively enter a language (for example, English) into a search box  530 , to search for the language list  531  on the touchscreen  150  for the language. If the language list  531  includes the language entered into the search box  530 , the language entered into the search box  530  may be highlighted on the touchscreen  150 , for the user to easily search for the language. The user interface  400  shown in  FIG. 4A  is used as an example. The electronic device  100  adds the email translation area  411  to the user interface  400 , in response to the operation on the suspend button  401 , where the email translation area  411  includes the result preview area  412 , and the result preview area  413  includes the translation result of the email body content. When the system language is simplified Chinese, the translation result of the email body content included in the result preview area  413  is simplified Chinese. It should be noted that in this embodiment of this application, the electronic device  100  may translate the email body content, in response to the operation on the suspend button  401 . Alternatively, the electronic device  100  may report the email body content to a cloud server for translation; and after the cloud server completes translation, the cloud server returns a translation result to the electronic device  100 , so that the electronic device  100  can present the translation result to the user. 
     In some other embodiments, for ease of closing the email translation area, as shown in  FIG. 6A , the email translation area  411  included in the user interface  410  further includes a setting bar  603 , and a close button  602  is provided in the setting bar  603 . In response to an operation on the close button  602 , the electronic device  100  may hide the email translation area  411 , and may display the user interface  400  on the touchscreen  150 . The user interface  400  may include a suspend button  401 . In this embodiment of this application, the close button  602  may be a character such as “x”, may be an identifier or the like, or may be “close”. This is not limited in this embodiment of this application. 
     In some other embodiments, the language of the translation result may alternatively be a language that is recorded by the electronic device  100  and that is set for previous email translation. For example, if the language that is recorded by the electronic device  100  and that is set for the previous email translation is French, the language used for the translation result is French. 
     In addition, for ease of viewing the translation result by the user, in some embodiments, as shown in  FIG. 6A , a pull-up button  601  may alternatively be provided in the setting bar  603 . If detecting a touch operation on the pull-up button  601 , the electronic device  100  may display the email translation area  411  on the touchscreen  150  in response to the operation. For example, the user interface on which the email translation area  411  may be displayed in full screen may be a user interface  600  shown in  FIG. 6C . Because the user interface  600  displays the translation result in full screen, it is conducive to view by the user. Moreover, for ease of making the user interface  600  return to the user interface  410 , in response to the operation on the pull-up button  601 , the pull-up button  601  may further be hidden from the setting bar  603  and a pull-down button  604  is displayed in the setting bar  603 , while the email preview area  411  is displayed in full screen on the touchscreen  150 . The electronic device  100  may exit full screen display of the email translation area  411 , in response to a touch operation on the pull-down button  603 . For example, the electronic device  100  may display the user interface  410  on the touchscreen  150 , in response to the touch operation on the pull-down button  604 . It should be noted that both the pull-up button  601  and the pull-down button  604  in this embodiment of this application may be displayed on the user interface  410  and the user interface  600 . For example, both the pull-up button  601  and the pull-down button  604  are displayed on the user interface  410 ; or the pull-up button  601  may be displayed on the user interface  410 , and the pull-down button  604  may be displayed on the user interface  600 . This is not limited. 
     To improve translation flexibility, in some other embodiments, as shown in  FIG. 7 a   - 1 , a language button  701  may further be provided in the setting bar  603 . If detecting an operation on the language button  701 , the electronic device  100  adds a language setting bar  705  to the user interface  410 . The language setting bar  705  includes a source language setting button  704  and a target language setting button  703 . The source language setting button  704  is used to set a language of to-be-translated content, and the target language setting button  703  is used to set a translated language of the to-be-translated content. For example, a user interface to which the language setting bar  705  has been added may be a user interface  700  shown in  FIG. 7 a   - 2 . It can be understood that, if detecting the operation on the language button  701 , the electronic device  100  may display the user interface  700  on the touchscreen  150  in response to the operation. The user may change a language of a translation result by using the target language setting button  703 . For example, if detecting an operation on the target language setting button  703 , the electronic device  100  may display a target-language list on the touchscreen  150  in response to the operation on the target language setting button  703 . A target-language list  720  shown in  FIG. 7 b    is used as an example. The user may perform selection from languages included in the target-language list  720 . For example, if the user selects French from the target-language list  720 , email body content is translated into French in response to an operation of the user for selecting French, so that the language of the translation result displayed in the touchscreen  150  is French. The source language setting button  704  is used to indicate a language used for the email body content. For example, if the language used for the email body content is English, “English” may also be displayed on the source language setting button  704 . For another example, if the language used for the email body content is Chinese, “Chinese” may also be displayed on the source language setting button  704 . It should be noted that in some embodiments, when the email body content includes both Chinese and English, if the electronic device  100  automatically sets a language to English by using the source language setting button  704 , content in English in the email body content is automatically translated into a language that is set by using the target language setting button. For another example, when the email body content includes both French and English, if the electronic device  100  automatically sets a source language to English and the user is familiar with English but is unfamiliar with French, the user may perform an operation on the source language setting button  704 , to display a language list corresponding to the email body content. The user may select French from the language list corresponding to the email body content, so that English that is automatically set by using the source language setting button  704  is changed to French, and content in French in the email body content can be translated into a language (for example, a target language is English) that is set by using the target language setting button  703 . This improves email viewing efficiency of the user. 
     Specifically, in some embodiments, the electronic device  100  may determine, by detecting a language included in an email body, the language list corresponding to the email body content. For example, if the email body content includes English and Chinese, the language list corresponding to the email body content includes English and Chinese. For another example, if the email body content includes Japanese, Korean, and English, the language list corresponding to the email body content includes Japanese, Korean, and English. 
     In addition, in some embodiments, the target-language list  720  may include languages supported by the electronic device  100 , or may include languages supported by the cloud server. For example, when the electronic device  100  translates the email body content, if the electronic device  100  supports English, Chinese, French, German, Russian, and Korean, the target-language list  720  includes English, Chinese, French, German, Russian, and Korean. For another example, when the electronic device  100  uploads the email body content to the cloud server for translation, if the cloud server supports English, Chinese, Japanese, German, and Latin, the target-language list  720  includes English, Chinese, Japanese, German, and Latin. In some embodiments, the electronic device  100  may upload, to the cloud server by using an artificial intelligence translation engine, the email body and the language that is set by using the target language setting button. Moreover, to ensure that the user knows an uploading prompt, before uploading, to the cloud server, the email body and the language that is set by using the target language setting button, the electronic device  100  may further prompt the user to determine whether to agree to upload of the email body to the cloud server. The user may be prompted to determine whether to agree to upload of the email body to the cloud server, by displaying a dialog box on the touchscreen  150  or in another manner. 
     For ease of collapsing the language setting bar  705 , in some embodiments, when the language setting bar  705  is displayed, the electronic device  100  may further hide the language setting bar  705  in response to an operation on the language button  701 . Moreover, for ease of finding, by the user, a button used for collapsing the language setting bar  705 , in some embodiments, in response to an operation on the language button  701 , the electronic device  100  may hide the language button  701  from the setting bar  603  and display a collapse button  702  in the setting bar  603 , in addition to adding the language setting bar  705  to the user interface  410 . In response to an operation on the collapse button  702 , the electronic device may hide the language setting bar  705 , display the language button  701  in the setting bar  603 , and hide the collapse button  702  from the setting bar  603 , that is, display the user interface  410  on the touchscreen  150 , as shown in  FIG. 7 a - l   . For ease of identifying the collapse button  702  by the user, the collapse button  702  may be named collapse. Certainly, the collapse button  702  may alternatively have another name. Any button that can be used to hide the language setting bar  705  can be understood as the collapse button  702 . 
     For ease of performing an operation by the user, in some other embodiments, as shown in  FIG. 8 , the electronic device  100  may display a shortcut menu  800  on the touchscreen  150  in response to a hard press operation of the user on the suspend button  401 . The shortcut menu  800  includes a source language setting button  801  and a target language setting button  802 . When the email body content includes two or more languages, the user may modify, by performing an operation on the source language setting button  801 , an email text part that needs to be translated. For a specific implementation, refer to the description in the foregoing embodiment about modifying, by using the source language setting button  704 , an email text part that needs to be translated. The user may change, by performing an operation on the target language setting button  802 , a required translated language of the email body content. For a specific implementation, refer to the description in the foregoing embodiment about changing a required translated language of the email body content by using the target language setting button  703 . Details are not described herein again. In addition, the suspend button  401  in this embodiment of this application may be related to languages that are set by using the source language setting button and the target language setting button. For example, if a language is set to English by using the source language setting button  801  and a language is set to Chinese by using the target language setting button  802 , the suspend button  401  may be represented as a suspend button shown in  FIG. 8 . When a language is set to French by using the source language setting button  801  and a language is set to English by using the target language setting button  802 , the suspend button may be represented in a form shown in  FIG. 9 . It should be noted that the suspend button in this embodiment of this application may alternatively not be related to languages that are indicated by the source language setting button  801  and the target language setting button  802 . Regardless of languages indicated by the source language setting button  801  and the target language setting button  802 , suspend controls may be represented in a same form. This is not limited in this embodiment of this application. 
     As shown in  FIG. 10 , to indicate a function of the suspend button  401  to the user, in some other embodiments, in response to the touch operation on the area  304  in the email list  302 , the electronic device  100  may further display a prompt box  1000  on the touchscreen  150  when the email corresponding to the area  304  is opened. The prompt box  1000  includes prompt information, and the prompt information is used to indicate that the suspend button may be used for translating email content. For example, the prompt information may be “If an email needs to be translated, please tap the suspend control”, may be “Tap the button to translate an email”, or may be “Tap here for email translation”. The prompt box  1000  may be hidden after being displayed on the touchscreen  150  for preset duration, or a prompt box  404  may be hidden from the touchscreen  150  after a touch operation on an “Ok” control is detected. For example, the preset duration may be 20 seconds or 30 seconds. A manner of hiding the prompt box  404  is not limited in this embodiment of this application. 
     It can be understood that, the prompt box  1000  may be displayed when the user opens an email for the first time to view the email, where the prompt box  1000  includes the prompt information, and the prompt information is used to prompt translation of email content. Certainly, the prompt box  1000  may alternatively be displayed when an email is written for the first time. Alternatively, the prompt box  1000  may be displayed any time when an email is viewed or an email is written. 
     During specific implementation, when the electronic device  100  detects that the user interface for viewing an email (for example, an operation for viewing an email in the inbox) is opened for the first time, or that the user interface for writing an email is opened for the first time, the electronic device  100  may display the prompt box on a user interface illustrating email content details. For example, if the operation on the area  304  is an operation for viewing an email in the inbox for the first time, the prompt box  1000  is displayed on the user interface illustrating email content details. When the electronic device  100  detects an operation on the area  304  again or detects an operation on an area in which another email in the email list  302  is located, in response to the operation, the electronic device  100  displays, on the touchscreen  150 , a corresponding user interface illustrating email content details. In this case, the prompt box  1000  may not be displayed any more. 
     For another example, in response to detection of the operation on the area  304 , the electronic device  100  may further determine whether a language used for a body of the email with the email subject “Welcome to our company” sent by the sender Peter is the same as the system language. If the language used for the email body is different from the system language, the user interface illustrating email content details about the email with the email subject “Welcome to our company” sent by the sender Peter is displayed on the touchscreen  150 , and the prompt box  1000  is displayed on the user interface illustrating email content details. For example, as shown in  FIG. 10 , if the language used for the email body is the same as the system language, the prompt box  1000  may be hidden. 
     Specifically, in this embodiment of this application, the electronic device  100  may determine whether the language used for the email body is the same as the system language. Alternatively, the electronic device  100  may send the email body to the cloud server; the cloud server may determine the language used for the email body, and then send the language used for the email body to the electronic device  100 ; and the electronic device  100  may determine whether the language used for the email body is the same as the system language. Alternatively, the electronic device  100  may send the email body and the system language to the cloud server; and the cloud server may determine whether the language used for the email body is the same as the system language, and then return a determining result to the electronic device  100 . 
     For example, when the electronic device  100  needs to use the cloud server to determine whether the language used for the email body is the same as the system language, the electronic device  100  may send the email body to the cloud server by using the artificial intelligence translation engine. For another example, the electronic device  100  may alternatively send the email body and the system language to the cloud server by using the artificial intelligence translation engine; and the cloud server  304  may determine whether a language type of a body of the email indicated by a control  304  is consistent with a type of the system language, and then send a determining result to the electronic device  100 . If the language used for the email body is inconsistent with the system language, the prompt box  1000  is displayed on the user interface of the electronic device. 
     Because the email body content needs to be reported to the cloud server, to ensure that the user knows a reporting prompt, in some embodiments, the electronic device  100  may further display a dialog box on the user interface illustrating email content details, in response to the operation on the area  304 , where the dialog box includes information used to prompt the user to determine whether to agree to report the email body content to the cloud server. A dialog box  1100  shown in  FIG. 11  is used as an example. The dialog box  1100  includes an approval button  1101  and a rejection button  1102 . The approval button  1101  is used to indicate that the user agrees to send the email body content to the cloud server, and the rejection button  1102  is used to indicate that the user rejects sending of the email body content to the cloud server. If detecting an operation on the approval button  1101 , the electronic device  100  uploads the email body to the cloud server in response to the operation. If detecting an operation on the rejection button  1102 , the electronic device  100  does not upload the email body to the cloud server. In some embodiments, the dialog box  1100  may further include prompt information indicating that “If a user has not performed an operation when a preset duration expires, it is considered by default that the user agrees to upload email body to the cloud server”. The preset duration may be 10 s, or may be 5 s, 15 s, or the like. It should be noted that the dialog box  1100  may be referred to as a prompt box  1100 . This is not limited in this embodiment of this application. It should also be noted that in some embodiments, the dialog box  1100  may alternatively not include a rejection button  1102 , but includes information used to prompt the user to determine whether to agree to report the email body content to the cloud server, and the approval button  1101 . In this case, if detecting an operation on the approval button  1101 , the electronic device  100  uploads the email body to the cloud server in response to the operation. If the electronic device  100  has not detected an operation of the user on the approval button  1101  when preset duration (for example, 10 s or 5 s) expires, it is considered by default that the user rejects sending of the email body content to the cloud server. 
     It should also be noted that, the user interface  410  shown in  FIG. 4B , the user interface  600  shown in  FIG. 6C , and the user interface  700  shown in  FIG. 7 a   - 2  and  FIG. 7 b    may include the suspend button  401 , or may not include the suspend button  401 . This is not limited in this embodiment of this application. 
     The foregoing uses the user interface for viewing a received email as an example for describing the email translation method in this embodiment of this application in detail. The electronic device  100  may further display, on the touchscreen  150 , the user interface for writing an email, in response to a user operation, where the user interface for writing an email may include a suspend button and an email writing area, and the email writing area includes content written by a user. If detecting an operation on the suspend button, the electronic device  100  adds an email translation area to the user interface for writing an email, where the email translation area includes a result preview area, and the result preview area includes a translation result of the content written by the user. It can be understood that, if detecting the operation on the suspend button, the electronic device  100  displays, on the touchscreen  150 , a user interface including the translation result of an email content written by the user. It can be understood that, for ease of performing an operation by the user, the electronic device may insert the translation result into the email writing area or replace the written content with the translation result in the email writing area, in response to the user operation. In this embodiment of this application, a function bar may further be provided in the email translation area, where the function bar includes at least one of a replacement button and an insertion button. The electronic device may replace the content written by the user in the email writing area with the translation result in response to an operation on the replacement button, or the electronic device may add the translation result to the email writing area in response to an operation on the insertion button. 
     For example, as shown in  FIG. 12A , the electronic device  100  displays the user interface  400  on the touchscreen  150 . The user interface  400  displays an email sent by a sender (for example, the sender is Peter), where a language of email body content is English. Then, if detecting a touch operation on a replay button  1213 , the electronic device  100  displays, on the touchscreen  150  in response to the operation, a user interface for replying to the email with the subject “Welcome to our company” sent by the sender Peter. For example, if a language with which the user is familiar is Chinese, after the user has written an email in Chinese to be replied to Peter, the user interface for replying to the email with the subject “Welcome to our company” is shown as a user interface  1200  in  FIG. 12B . The user interface  1200  includes a suspend button  401  and an email writing area  1204 , where the email writing area  1204  includes content written by the user in Chinese. In addition, the user interface  1200  may further include at least one of the following controls: a button  1201  for email sending, a button  1203  for canceling email reply, a button  1202  for adding a new recipient, and the like. If detecting an operation on the suspend button  401 , the electronic device  100  adds an email translation area  1212  to the user interface  1200  in response to the operation, where the email translation area  1212  includes a result preview area  1213  and a function bar  1214 . The result preview area  1213  includes a translation result of the content that is written by the user in Chinese and that is included in the email writing area  1204 . The function bar  1214  includes at least one of an insertion button  1205  and a replacement button  1206 . It can be understood that, a user interface after the email translation area  1212  is added to the user interface  1200  may be a user interface  1210  shown in  FIG. 12C . For example, to simplify the user operation, the electronic device  100  automatically sets a language to English by using a target language setting button, based on the language, which is English, used for the body of the email with the subject “Welcome to our company” sent by the sender Peter. In this case, if detecting an operation on the suspend button  401 , the electronic device  100  displays the translation result in the result preview area  1213  in English in response to the operation. It should be understood that the user may alternatively set a target language by performing an operation on the target language setting button. 
     The user interface  1210  shown in  FIG. 12C  is used as an example. The email translation area  1212  further includes the function bar  1214 , and the function bar includes the at least one of the insertion button  1205  and the replacement button  1206 . Therefore, in response to an operation on the replacement button  1206 , the electronic device  100  may replace the content written by the user included in the email writing area  1212  with the translation result, and display the translation result in the email writing area  1212 . This may be shown as a user interface  1300  in  FIG. 13 . This facilitates the user operation, and improves email writing efficiency. In some embodiments, the electronic device  100  may alternatively hide the email translation area  1212  in response to an operation on the replacement button  1206 . For example, a user interface on which the translation result has been displayed in the email writing area  1212  and the email translation area  1212  has been hidden may be a user interface  1300  shown in  FIG. 13 . 
     Further, to ensure accuracy of the email content obtained after the replacement, the user may modify content on the user interface  1300  obtained after the replacement or modify the content in the result preview area  1213 . It should be noted that, for ease of learning about a function of the replacement button  1206  by the user, in some embodiments, the replacement button  1206  may be named “replace” to indicate the function of the replacement button  1206  to the user; or the replacement button  1206  may be set to a symbol or an identifier used for indicating replacement, to indicate the function of the replacement button  1206  to the user. 
     In addition, in some other embodiments, as shown in  FIG. 12C , when the function bar  1214  further includes the insertion button  1205 , in response to an operation on the insertion button  1205 , the electronic device  100  may add the translation result to the email writing area  1204 , and display the content written by the user and the translation result. This is shown as, for example, a user interface  1400  in  FIG. 14 . In some other embodiments, the email translation area  1212  may alternatively be hidden. For example, a user interface after the translation result is added to the email writing area  1204  may be the user interface  1400  shown in  FIG. 14 . The user interface  1400  may include an area  1401  and an area  1402 , where the area  1401  includes the content written by the user, and the area  1402  is the translation result. It should be noted that, in  FIG. 14 , the content written by the user may be located before the translation result, or the content written by the user may be located after the translation result. This is not limited. For ease of learning about a function of the insertion button  1205  by the user, the insertion button  1205  may be set to “insert”, the insertion button  1205  may be set to “copy” or the like, or the insertion button  1205  may be set to a symbol or an identifier used for indicating copying or insertion. This is not limited. 
     It should be understood that, for ease of performing an operation by the user, the user interface  1210  may further include a setting bar  1215 . The setting bar  1215  may be provided with at least one of a pull-up button  1207 , a language button  1208 , and a close button  1209 . For functions of the pull-up button  1207 , the language button  1208 , and the close button  1209 , refer to related descriptions of the pull-up button  601 , the language button  701 , and the close button  602 . Details are not described herein again. 
     For another example, as shown in  FIG. 15 a   - 1 , the electronic device  100  displays a user interface  1500  on the touchscreen  150 . The user interface  1500  includes an email writing area  1502  and a suspend button  1501 , where the email writing area  1502  includes content written by a user in Chinese. The electronic device  100  may add an email translation area  1503  to the user interface  1500  in response to an operation on the suspend button  1501 . The email translation area  1503  includes a result preview area  1512  and a function bar  1513 . The result preview area  1512  includes a translation result of the content written by the user in Chinese. The function bar  1513  includes at least one of an insertion button  1507  and a replacement button  1508 . In addition, for ease of performing an operation by the user, in some embodiments, the email translation area  1503  further includes a setting bar  1511 . The setting bar  1511  includes at least one of a pull-up button  1504 , a language button  1505 , and a close button  1506 . For example, a user interface after the email translation area  1503  is added to the user interface  1500  may be shown as a user interface  1510  in  FIG. 15 a   - 2 . It should be noted that, for functions of the pull-up button  1504 , the language button  1505 , the close button  1506 , the insertion button  1507 , and the replacement button  1508 , reference may be made to the functions of the pull-up button  1207 , the language button  1208 , the close button  1209 , the insertion button  1205 , and the replacement button  1206 . Details are not described herein again. 
     In some embodiments, to avoid misoperations performed by the user, as shown in  FIG. 15 b   , the electronic device  100  may further pop up a prompt box  1520  in response to an operation on the replacement button  1508 . The prompt box  1520  includes prompt information and an approval button  1521 , where the prompt information is used to prompt the user to determine whether to replace the content written by the user with the translation result. In response to an operation on the approval button  1521 , the electronic device may replace the content written by the user in the email writing area  1502  with the translation result in the result preview area  1512 , display the translation result in the email writing area  1502 , and further hide the email translation area  1503 . The prompt box  1520  may further include a rejection button  1522 . If detecting an operation on the rejection button  1522 , in response to the operation, the electronic device  100  rejects replacement of the content written by the user in the email writing area  1502  with the translation result in the result preview area  1512 , In addition, in some embodiments, preset duration such as 10 s may further be set. If detecting that no operation has been performed on the approval button  1521  when 10 s expires, the electronic device  100  may consider by default that the user agrees to replace the content written by the user with the translation result, or may consider by default that the user rejects replacement of the content written by the user with the translation result. 
     Moreover, in response to a user operation, the electronic device  100  may further display the user interface for email forwarding, where the user interface for email forwarding includes an email writing area and a suspend button. When the electronic device  100  detects an operation on the suspend button on the user interface for email forwarding, for a specific implementation in which the electronic device  100  responds to the operation, reference may be made to the foregoing implementation in which the electronic device  100  responds to the operation on the suspend button on the user interface for email reply. 
     It should also be noted that, the foregoing describes only translation of an email body, and the electronic device  100  may further translate an email subject, in response to the operation on the suspend button. Then, the translation result includes a translation result of the subject. 
     In addition, it should also be noted that, after the email has been written by using a familiar language on the user interface for writing an email and the content written by the user has been translated by using an existing technology, the electronic device  100  may further display at least one of the insertion button and the replacement button while displaying the translation result on the touchscreen  150 , so that the user directly adds the translation result to the email body without a need to copy the translation result. 
     The user interface  700  shown in  FIG. 7  is used as an example. In an embodiment of this application, if the cloud server is used to translate an email body and/or an email subject, the electronic device  100  may obtain, based on a method shown in  FIG. 16 , a language supported by the cloud server, to generate a target-language list.  FIG. 16  shows a method for obtaining, by the electronic device, the language supported by the cloud server. The method includes the following steps: 
     Step  1601 : An email client of the electronic device  100  receives an operation for opening the email client. For example, the operation for opening the email client may be a touch operation on an email icon, or may be a quick gesture operation for opening an email. This is not limited. 
     Step  1602 : The electronic device  100  sends an initialization request to an AI translation engine (artificial intelligence translation engine) by using the email client. 
     Step  1603 . After receiving the initialization request, the AI translation engine performs service binding with the email client. Service binding may be: The AI translation engine may send related information of the email client (for example, email content written by a user) to the cloud server, and the cloud server may also deliver related information of the email client (for example, a translation result of the email content written by the user) to an AT translation engine. 
     Step  1604 : The email client of the electronic device  100  sends a request of obtaining the language supported by the cloud server to the cloud server by using the AI translation engine. 
     Step  1605 . After receiving the request sent by the electronic device  100 , the cloud server returns the language supported by the cloud server to the email client of the electronic device  100  based on the request by using the AI translation engine. 
     Step  1606 : After receiving the language supported by the cloud server, the email client of the electronic device  100  generates a target-language list based on the language supported by the cloud server, where the target-language list includes the language supported by the cloud server. 
     In addition, the electronic device  100  may further obtain the language supported by the cloud server from the cloud server, in response to an operation for opening an inbox or outbox or an operation on a suspend button. A manner of triggering obtaining of the language supported by the cloud server is not limited in this embodiment of this application. 
     In this embodiment of this application, when the electronic device  100  detects an operation on the suspend button on the user interface  400  shown in  FIG. 4A , in some embodiments, a method shown in  FIG. 17A  and  FIG. 17B  may be used to display, in response to the operation on the suspend button, a user interface including a translation result. 
     Specifically, as shown in  FIG. 17A  and  FIG. 17B , the method for displaying the user interface including a translation result in this embodiment of this application includes the following steps. 
     Step  1701 : An email client of the electronic device  100  receives an operation of a user for opening an email in an inbox. For example, the operation for opening an email in the inbox may be touching an area in which an email in the email list shown in  FIG. 3  is located. 
     Step  1702 : The email client of the electronic device  100  sends a language detection request to a cloud server by using an AI translation engine, where the language detection request includes email content that needs to be translated (for example, an email body and an email subject). 
     Step  1703 : After receiving the language detection request, the cloud server determines a language used for the email content that needs to be translated, and sends, to the email client by using the AI translation engine, the language used for the email content that needs to be translated. 
     Step  1704 : After receiving the language used or the email content that needs to be translated, the email client of the electronic device  100  compares the language used for the email content that needs to be translated with a system language, and determines that the language used for the email content that needs to be translated is different from the system language. 
     Step  1705 : The email client of the electronic device  100  displays a prompt box on a touchscreen  150 , where the prompt box includes information used to indicate a function of the suspend button to the user. For example, the information used to indicate the function of the suspend button to the user may be “Tap the button to translate an email” or “If an email needs to be translated, please tap here”. 
     Step  1706 : The email client of the electronic device  100  receives an operation of the user on the suspend button. 
     Step  1707 : The email client of the electronic device  100  determines that the email content needs to be translated into a target language. 
     Step  1708 : The email client of the electronic device  100  sends a translation request to the cloud server by using the A translation engine, where the translation request includes the target language. 
     Step  1709 : After receiving the translation request, the cloud server translates, based on the target language included in the translation request, the email content that needs to be translated, to obtain a translation result; and returns the translation result to the email client by using the AI translation engine. 
     Step  1710 : After receiving the translation result, the email client of the electronic device  100  displays, on the touchscreen  150 , the user interface including the translation result. For ease of view by the user, a paragraph of the to-be-translated content may be in one-to-one correspondence to a paragraph of the translation result. 
     It can be understood that in this method, the electronic device may perform step  1701  to step  1704  and step  1706  to step  1710 , and does not perform step  1705 . 
     It should be noted that the user may further modify, copy, analyze, select-all, hide, or perform other operations on the translation result. For example, a modification button, a copy button, an analysis button, a select-all button, and/or a hide button may be added. In response to an operation on a button, the user may modify, copy, analyze, select-all, and/or hide the translation result. 
     In this embodiment of this application, when the electronic device  100  detects an operation on the suspend control on the user interface  1200  shown in  FIG. 12B , in some embodiments, a method shown in  FIG. 18  may be used to display, in response to the operation on the suspend control, a user interface including a translation result. 
     Specifically, as shown in  FIG. 18 , another method for displaying the user interface including a translation result in this embodiment of this application includes the following steps. 
     Step  1801 : An email client of the electronic device  100  receives an operation for displaying a user interface for writing an email, where the user interface for writing an email may be a user interface for email reply, a user interface for email forwarding, a user interface for writing a new email, or the like. 
     Step  1802 : The email client of the electronic device  100  obtains an email body and/or an email subject that are/is entered by a user on the user interface. 
     Step  1803 : The email client of the electronic device  100  receives an operation on the suspend button. 
     Step  1804 : The email client of the electronic device  100  determines to translate the email body and/or the email subject into a target language. 
     Step  1805 : The email client of the electronic device  100  sends a translation request to a cloud server by using an AI translation engine, where the translation request includes the email body and/or the email subject that need/needs to be translated, and the target language. 
     Step  1806 : After receiving the translation request, the cloud server translates, into the target language, the email body and/or the email subject that need/needs to be translated, to obtain a translation result; and returns the translation result to the email client by using the A translation engine. 
     Step  1807 : After receiving the translation result, the email client of the electronic device  100  displays, on a touchscreen  150 , the user interface including the translation result. 
     It should be noted that the user may select-all, modify, share, or perform other operations on the translation result. 
     In addition, a control for determining whether to display a suspend button may further be added to an email setting screen in the embodiments of this application, so that a user can set, depending on a requirement of the user, whether to display the suspend button on a user interface for viewing or writing an email. For example, as shown in  FIG. 19 a   , an email setting screen  1900  includes a button  1901  used for enabling or disabling a function of displaying the suspend button. It should be noted that the email setting screen  1900  may be a setting screen of email. For example, the electronic device  100  may display a shortcut menu  1910  on the touchscreen  150  in response to a touch operation on the inbox, where the shortcut menu  1910  includes account management  1911 , as shown in  FIG. 19 b   - 1 . In some other embodiments, the shortcut menu  1910  may further include “account login”, “draft box”, “sent”, “deleted”, “inbox”, and other buttons. A quantity and functions of buttons included in the shortcut menu  1910  are not limited in this embodiment of this application. The electronic device  100  may display a user interface  1920  on the touchscreen  150  in response to an operation of the user on the account management  1911  (for example, tapping the account management  1911 ). The user interface  1920  includes a setting button  1921 . Moreover, the user interface may further include an email management button, a contact management button, and the like. The electronic device  100  may display the email setting screen  1900  in response to an operation on the setting button  1921 , as shown in  FIG. 19 a   . It can be understood that the email setting screen  1900  may alternatively be an email-specific setting screen on a system setting screen. For example, as shown in  FIG. 19 c   - 1  and  FIG. 19 c   - 2 , the electronic device  100  may display the system setting screen  510  on the touchscreen  150  in response to an operation on the setting icon. Then, the electronic device  100  may display a user interface  1940  on the touchscreen  150  in response to an operation on a button  1930  used for applications and notifications included on the system setting screen  510 . The user interface  1940  includes a button  1941  used for email setting. Furthermore, the user interface  1940  may further include buttons for setting other applications (such as WeChat, settings, and camera) installed on the electronic device  100 . The electronic device  100  may display the email setting screen  1900  on the touchscreen  150  in response to a touch operation on the button  1941  used for email setting. 
     Moreover, languages included in a target-language list may further be a set of languages supported both by the electronic device  100  and the cloud server. For example, both the electronic device  100  and the cloud server can support a specific language (for example, English) in the target-language list. Therefore, content of an email body and/or an email subject may be translated on the electronic device  100 , or content of an email body and/or an email subject may be translated on the cloud server. In this case, the user may perform corresponding setting on priorities of emails. For example, an email translation location button, for example, a button  1903  and a button  1902 , may be added to the email setting screen  1900 . For example, as shown in  FIG. 19 a   , if the button  1902  is selected, the electronic device  100  preferentially transmits an email on the cloud server. 
     The foregoing embodiments in the embodiments of this application may be used in combination. 
     In the embodiments provided in this application, the methods provided in the embodiments of this application are described from a perspective of the electronic device that serves as an execution body. 
       FIG. 20  shows an electronic device  2000  according to this application. For example, the electronic device  2000  includes at least one processor  2010 , a memory  2020 , and a touchscreen  2030 . The processor  2010 , the memory  2020 , and the touchscreen  2030  are coupled to each other. Coupling in this embodiment of this application may be a communication connection, or may be in an electrical form or another form. 
     Specifically, the memory  2020  is configured to store a program instruction. 
     The touchscreen  2030  is configured to display a user interface. 
     The processor  2010  is configured to invoke the program instruction stored in the memory  2020 , so that the electronic device  2000  is enabled to perform the steps performed by the electronic device in the email translation methods provided in the embodiments of this application. It should be understood that the electronic device  2000  may be configured to implement the email translation methods in the embodiments of this application. For related features, refer to the foregoing descriptions. Details are not described herein again. 
     In possible implementation, the displaying mentioned above may be implemented by using a display screen. The display screen has a displaying function, and the display screen may have a touch function or may not have a touch function. An operation on a touchscreen may be implemented by using a virtual key, or may be implemented by tapping a touchscreen. An operation on a non-touchscreen may be implemented by using a physical key. 
     It can be understood that the foregoing embodiments use email as an example for description, and can also be applied to translation of a variety of content. For example, if a user enters Chinese on a search page of a browser, the search page displays a suspend button; and in response to an operation of the user for tapping the suspend button, the entered Chinese can be translated into English. In this way, information related to English can be searched for. For another example, when a user enables chat software, a user interface of the chat software displays English written by the user, and the user interface of the chat software displays a suspend button; and in response to an operation of the user for tapping the suspend button, English can be translated into Chinese. For specific descriptions, refer to the descriptions in the foregoing embodiments. 
     A person skilled in the art can clearly understand that the embodiments of this application may be implemented by hardware, or may be implemented by a combination of hardware and software. When it is implemented by using software, code that implements the foregoing functions may be stored in a computer-readable medium. 
     In summary, what is described above is merely embodiments of the technical solutions of this application, but is not intended to limit the protection scope of this application. Any modification, equivalent replacement, or improvement made without departing from the spirit and principle of this application shall fall within the protection scope of this application.
