     DESCRIPTION OF EMBODIMENTS 
     To make the objectives, technical solutions, and advantages of embodiments of the present invention clearer, the following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. 
     A terminal mentioned in the embodiments of the present invention may include but is not limited to mobile communications devices such as a mobile phone, a personal digital assistant (Personal Digital Assistant, PDA), a tablet computer, a portable device (for example, a portable computer), or may include a device with a touchscreen, such as an automatic teller machine (Automatic Teller Machine, ATM), or may include a terminal with a touchscreen and physical buttons. This is not limited in the embodiments of the present invention. 
     A method mentioned in the embodiments of the present invention is to resolve a prior-art technical problem: a user can only implement a one-handed operation on a large-screen terminal with a single specific gesture, and a manner of generating a one-handed operation interface is onefold; and may further resolve a prior-art technical problem: there is a shortage of an adjustment manner of adjusting a size and a location of the generated one-handed operation interface, and human-machine interaction is not intelligent enough. 
     The following describes the technical solutions of the present invention in detail by using specific embodiments. The following several specific embodiments may be combined with each other, and a same or similar concept or process may not be described repeatedly in some embodiments. 
       FIG. 1  is a schematic flowchart of Embodiment 1 of a method for processing a user interface of a terminal according to an embodiment of the present invention. This embodiment relates to a specific process in which a terminal presents a one-handed operation interface (that is, the following first interface) to a user by using a first operation input by the user and according to a first touch event associated with the first operation. As shown in  FIG. 1 , the method includes the following steps. 
     S 101 : Obtain a first operation input by a user, and determine a first touch event corresponding to the first operation, where the first touch event includes at least one of: a first swipe event, in a navigation area of the terminal, that is collected by the terminal according to the first operation; a second swipe event, on a physical button of the terminal, that is collected by the terminal according to the first operation; a double-tap event, on a virtual button in the navigation area, that is collected by the terminal according to the first operation; or a first touch-and-hold event, on the virtual button in the navigation area, that is collected by the terminal according to the first operation. 
     Specifically, the terminal obtains the first operation input by the user, and the first operation may be a swipe operation performed by the user in the navigation area of the terminal, or may be a swipe operation performed by the user on the virtual button in the navigation area. For the swipe operation performed by the user in the navigation area, the user swipes up, down, left or right in the navigation area without pressing the virtual button in the navigation area. For the swipe operation on the virtual button, the user may press a virtual button in the navigation area and swipe up, down, left or right. Optionally, the first operation may be a swipe operation performed by the user on the physical button of the terminal (the swipe operation herein and an operation of pressing the physical button may be simultaneously performed), or may be a touch-and-hold operation on a touchscreen of the terminal, or may be a touch-and-hold operation on the physical button of the terminal, or the like. It should be noted that the foregoing navigation area may be a virtual navigation area in an Android system, for example, may be shown in  FIG. 2 ; or the foregoing navigation area may be a task area bar provided with preset applications such as Messages and Phone in an iPhone operating system (iPhone Operating System, iOS for short). When the navigation area is the virtual navigation area in the Android system, the foregoing virtual button may be some virtual controls having same functions as substantive buttons, for example, “home button (home)” and “back button (back)” of the terminal. When the navigation area is the task area bar provided with the preset applications such as Messages and Phone in the iOS system, the virtual button may be some virtual icons in the task area bar, and the virtual icons include but are not limited to the preset applications such as Messages and Phone. The foregoing physical button refers to a substantive button on the terminal. 
     Optionally, the terminal may obtain, by using a preset user interface, the first operation input by the user, or may collect, by using some application software at an underlying layer, the first operation input by the user, or may collect, by using hardware such as a pressure sensor, a timer, or a speed sensor, the first operation input by the user. This embodiment of the present invention sets no limitation to an obtaining manner in which the terminal obtains the first operation input by the user. 
     After the terminal obtains the first operation input by the user, the terminal extracts, according to the first operation, a reference basis for presenting the first interface by the terminal, that is, obtains the first touch event. When the first operation is the swipe operation performed by the user in the virtual navigation area of the terminal, the first touch event determined by the terminal is the first swipe event. An Android mobile phone is used as an example, and a navigation area may be shown in  FIG. 2 . When the first operation is the swipe operation performed by the user on the physical button of the terminal, and the user touches at least one button in the swipe operation on the physical button, the first touch event determined by the terminal is the second swipe event. When the first operation is a double-tap operation performed by the user on the virtual button in the navigation area of the terminal, the first touch event determined by the terminal is the double-tap event. When the first operation is a touch-and-hold operation performed by the user on the virtual button in the navigation area, the first touch event determined by the terminal is the first touch-and-hold event. 
     S 102 : Present, in a preset area of a display of the terminal according to the first touch event, a first interface for the user to operate with one hand, where content of interface elements of the first interface is the same as content of interface elements of a second interface displayed on the display of the terminal, and sizes of the interface elements of the first interface are sizes of the interface elements of the scaled-down second interface; or content of interface elements of the first interface is the same as content of some interface elements of interface elements of the second interface, and sizes of the interface elements of the first interface are the same as sizes of the some interface elements. 
     Specifically, in the first touch event determined by the terminal, the terminal may obtain parameters related to the first touch event, such as a coordinate parameter, a time parameter, a speed parameter, a direction parameter, and a quantity of taps. These parameters may help the terminal to determine whether to generate the first interface, so as to help a user to perform a one-handed operation. The first interface may be simply understood as a small screen or a small window (compared with the display of the terminal). 
     Optionally, the content of the interface elements of the first interface may be the same as the content of the interface elements of the second interface displayed on the display, the sizes of the interface elements of the first interface are obtained by scaling down the sizes of the interface elements of the original second interface, and a size of the first interface (that is, a window size of the first interface) is a size of the scaled-down second interface. For a scale, a value of the scale may be preset in the terminal (for example, a transform value may be preset in a processor inside the terminal), and the transform value includes compression ratios of the window in a horizontal direction and in a vertical direction, so that the terminal may implement, according to the transform value, a function of scaling down the first interface and the interface elements of the first interface at any ratio. 
     Optionally, the content of the interface elements of the first interface may be the same as content of some interface elements of the interface elements of the second interface, the sizes of the interface elements of the first interface are the same as the sizes of the some interface elements, and a size of the first interface (that is, a window size of the first interface) is smaller than a size of the second interface. This case may be understood as follows: A display location and the sizes of the interface elements of the second interface on the display remain unchanged, and the generated first interface may be displayed above the second interface on the display. The first interface may be an independent window (similar to a screenshot window in instant messaging software), the window includes some interface elements of the second interface on the display, and when the user operates the first interface with one hand, interface elements that can be touched by a finger are only some interface elements in the first interface. 
     It should be noted that, both the content of the interface elements of the first interface and the content of the interface elements of the second interface may be some application software APP on the terminal or may be some option switches. In addition, that the content of the interface elements of the first interface is the same as the content of the interface elements of the second interface may be that functions of the interface elements or icons of APPs or icons of option switches may be the same. For example, when content of an interface element of the first interface is a WeChat icon, and content of an interface element of the second interface is also a WeChat icon, it indicates that the content of the interface element of the first interface is the same as the content of the interface element of the second interface. 
     According to the method for processing a user interface of a terminal provided in this embodiment of the present invention, a terminal may obtain a first touch event according to different first operations input by a user, and present, according to the first touch event, a first interface that can be operated by the user with one hand. That is, according to the method provided in this embodiment, the user may trigger, by using different first operations in a navigation area of the terminal, the terminal to generate the first interface, that is, the method provided in this embodiment of the present invention diversifies a manner of triggering the terminal to generate the first interface, brings more possibilities to user experience, and improves intelligence of human-machine interaction. In addition, according to the method provided in this embodiment of the present invention, the user may trigger, by using different first operations not only in the navigation area but also on a virtual button or a substantive button, the terminal to generate the first interface, which further diversifies the manner of triggering the terminal to generate a one-handed operation interface, brings more possibilities to user experience, and further improves intelligence of human-machine interaction. 
     Further, based on the foregoing embodiment, this embodiment relates to an execution process in which the terminal determines specific content of the first touch event according to the first operation. Specifically, when the terminal determines the first touch event according to the first operation, the terminal actually determines values of some parameters brought by the first operation. 
     When the first operation is the swipe operation performed by the user in the virtual navigation area of the terminal, the first touch event determined by the terminal is the first swipe event. In the first swipe event, the terminal actually determines specific parameters in the first swipe event, and the parameters include a swipe track corresponding to the first operation in the navigation area, a swipe speed corresponding to the first operation in the navigation area, and a swipe direction corresponding to the first operation in the navigation area. 
     When the first operation is the swipe operation performed by the user on the physical button of the terminal, and the user touches at least one button in the swipe operation on the physical button, the first touch event determined by the terminal is the second swipe event. In the second swipe event, the terminal actually determines specific parameters in the second swipe event, and the parameters include a type of the physical button touched in the first operation, a quantity of physical buttons touched in the first operation, a swipe track of the first operation on the physical button touched in the first operation, a swipe speed of the first operation on the physical button touched in the first operation, and a swipe direction of the first operation on the physical button touched in the first operation. 
     When the first operation is the double-tap operation performed by the user on the virtual button in the navigation area of the terminal, the first touch event determined by the terminal is the double-tap event. In the double-tap event, the terminal actually determines specific parameters in the double-tap event, and the parameters include a type of the virtual button touched in the first operation, and a quantity of taps of the first operation on the virtual button touched in the first operation. The type of the virtual button includes a virtual home button, a virtual back button, and a virtual multitasking button. 
     When the first operation is the touch-and-hold operation performed by the user on the virtual button in the navigation area, the first touch event determined by the terminal is the first touch-and-hold event. In the first touch-and-hold event, the terminal actually determines specific parameters in the first touch-and-hold event, and the parameters include the type of the virtual button touched in the first operation, and contact duration of the first operation on the virtual button touched in the first operation. 
     Based on the foregoing embodiment, in a possible implementation manner of this embodiment of the present invention, this embodiment relates to a specific process in which the terminal presents the first interface on the display according to the first swipe event when the first touch event is the first swipe event. That is, the step S 102  specifically includes: after determining that the swipe track corresponding to the first operation in the navigation area and the swipe speed corresponding to the first operation in the navigation area meet a first preset condition, the terminal presents the first interface on the display according to the swipe direction corresponding to the first operation in the navigation area. 
     Specifically, the terminal receives the first operation input by the user, and the first operation is the swipe operation performed by the user in the navigation area of the terminal, so that the terminal may determine the first swipe event according to the swipe operation. It should be noted that the first swipe event may include multiple independent events, for example, may include one DOWN event (DOWN Event), multiple continuous MOVE events (MOVE Event), and one UP event (UP Event), and each event includes various types of information in this event, such as event coordinates, an event type, an event time, and an event flag (Event flag). 
     The terminal may determine, according to the DOWN event and the UP event in the first swipe event, the swipe track (that is, a swipe distance) corresponding to the first operation in the navigation area. For example, the terminal may calculate, according to a difference between coordinates of the DOWN event and coordinates of the UP event, the swipe track corresponding to the first operation in the navigation area; or the terminal may determine, according to the DOWN event, the MOVE events, and the UP event, the swipe track corresponding to the first operation in the navigation area (the first swipe event in this case includes multiple continuous MOVE events whose tracks are overlapped), and the swipe track in this case may be understood as total swipe displacement. At the same time, the terminal may further obtain a time at which the DOWN event occurs and a time at which the UP event occurs in the first swipe event, to obtain, by means of calculation, a time consumed by the entire first swipe event; and then obtain, by means of calculation according to the total swipe track and the time consumed by the first swipe event, the swipe speed corresponding to the first operation in the navigation area. 
     After determining the swipe track corresponding to the first operation in the navigation area and the swipe speed corresponding to the first operation in the navigation area, the terminal determines whether the swipe track and the swipe speed meet the first preset condition. The first preset condition includes a first threshold range that the swipe track corresponding to the first operation in the navigation area should meet and a second threshold range that the swipe speed corresponding to the first operation in the navigation area should meet. Only after determining that the swipe track corresponding to the first operation in the navigation area meets the first threshold range and the swipe speed corresponding to the first operation in the navigation area meets the second threshold range, the terminal presents the first interface on the display according to the swipe direction corresponding to the first operation in the navigation area. 
     For example, as shown in  FIG. 3 , when the first operation performed by the user in the navigation area is swiping from left to right, that is, the swipe direction that is corresponding to the first operation in the navigation area and is in the first swipe event determined by the terminal is from left to right, and the terminal records coordinates and a press time point of a DOWN event at a moment when the user presses with a finger, and records coordinates and a lift time point of an UP event at a moment when the finger lifts up after swiping. Then the terminal may obtain, by means of calculation according to a difference between the coordinates of the DOWN event and the coordinates of the UP event, the swipe track corresponding to the first operation in the navigation area, and may obtain, by means of calculation according to a difference between the press time point of the DOWN event and the lift time point of the UP event, a swipe time corresponding to the first operation in the navigation area, so as to obtain the swipe speed corresponding to the first operation in the navigation area. Afterwards, the terminal determines whether the swipe track corresponding to the first operation in the navigation area and the swipe speed corresponding to the first operation in the navigation area meet the first preset condition. If the swipe track corresponding to the first operation in the navigation area and the swipe speed corresponding to the first operation in the navigation area meet the first preset condition, the terminal presents the first interface on the display according to the left-to-right swipe direction corresponding to the first operation in the navigation area. Optionally, the first interface may be displayed at the right side of the display (as shown in  FIG. 3 ). In  FIG. 3 , a window of a “content area” is the first interface, and a blank area is an area on the display other than the first interface. The blank area may be provided with no content, or may be provided with some function option switches for the user to set some parameter values, for example, to set luminance and a color of an icon in the content area, as long as it is ensured that content set in the blank area is different from content of interface elements in the content area. This is true of a “content area” and a “blank area” in all the following accompanying drawings. When the first operation performed by the user in the navigation area is swiping from right to left, the first interface may be displayed at the left side of the display (as shown in  FIG. 4 ). It should be noted that, when the first operation is a swipe operation, a swipe direction corresponding to the first operation in the navigation area may be in a one-to-one correspondence with a location of the first interface presented on the display, or a correspondence between a swipe direction corresponding to the first operation in the navigation area and a location of the first interface presented on the display may not be limited. It should be noted that, in  FIG. 3 , if the user swipes from left to right in the navigation area, the terminal presents the first interface on the display, and then if the user continues to swipe from right to left in the navigation area, the terminal restores the original second interface. In  FIG. 4 , after the first interface is presented, a process of restoring the original interface is similar to that in  FIG. 3 , and a swipe direction only needs to be opposite to a swipe direction of a swipe operation that triggers the terminal to present the first interface. 
     Optionally, when the first operation is swiping up and down in the navigation area by the user, an effect diagram of the first interface presented by the terminal may be shown in  FIG. 5 . When the first operation is pressing a virtual button in the navigation area and swiping up and back to the virtual button by the user, an effect diagram of the first interface presented by the terminal may be shown in  FIG. 6 . When the first operation is pressing a virtual button in the navigation area and swiping down by the user, an effect diagram of the first interface presented by the terminal may be shown in  FIG. 7 . When the first operation is pressing a virtual button in the navigation area and swiping left by the user, an effect diagram of the first interface presented by the terminal may be shown in  FIG. 8 . When the first operation is pressing a virtual button in the navigation area and swiping right by the user, an effect diagram of the first interface presented by the terminal may be shown in  FIG. 9 . When the first operation is any one of swiping up and down in the navigation area by the user, pressing a virtual button in the navigation area and swiping up and back to the virtual button by the user, or pressing a virtual button in the navigation area and swiping down by the user, in combination with an operation of swiping left or right in the navigation area by the user, or pressing a virtual button in the navigation area and swiping left or right by the user, the first interface presented by the terminal may be shown in  FIG. 10  or  FIG. 11 . 
     Based on the foregoing embodiment, in another possible implementation manner of this embodiment of the present invention, this embodiment relates to a specific process in which the terminal presents the first interface on the display according to the second swipe event when the first touch event is the second swipe event. That is, the step S 102  specifically includes: after determining that the type of the physical button touched in the first operation, the quantity of physical buttons touched in the first operation, the swipe track of the first operation on the physical button touched in the first operation, and the swipe speed of the first operation on the physical button touched in the first operation meet a second preset condition, the terminal presents the first interface on the display according to the swipe direction of the first operation on the physical button touched in the first operation. 
     Specifically, the terminal receives the first operation input by the user, and the first operation is the swipe operation performed by the user on the physical button of the terminal, so that the terminal determines the second swipe event according to the swipe operation. It should be noted that the second swipe event may also include multiple independent events, for example, may include one DOWN event (DOWN Event), multiple continuous MOVE events (MOVE Event), and one UP event (UP Event), and each event includes various types of information in this event, such as event coordinates, an event type, an event time, and an event flag (Event flag). 
     The terminal may determine, according to the DOWN event and the UP event in the second swipe event, the swipe track (that is, a swipe distance) of the first operation on the physical button touched in the first operation, or may determine, according to the DOWN event, the MOVE events, and the UP event, the swipe track corresponding to the first operation on the physical button. The terminal may further determine the swipe speed of the first operation on the physical button touched in the first operation. For a specific determining manner, refer to a specific process of determining the swipe track and the swipe speed that are corresponding to the first operation in the navigation area in the first possible implementation manner, and details are not repeatedly described herein. At the same time, the terminal may further determine, according to coordinates of the DOWN event or the UP event or the MOVE events, the type of the physical button touched in the first operation and the quantity of physical buttons touched in the first operation. 
     Therefore, after determining the type of the physical button touched in the first operation, the quantity of physical buttons touched in the first operation, the swipe track of the first operation on the physical button touched in the first operation, and the swipe speed of the first operation on the physical button touched in the first operation, the terminal determines whether the four parameters meet the second preset condition. If the type of the physical button touched in the first operation, the quantity of physical buttons touched in the first operation, the swipe track of the first operation on the physical button touched in the first operation, and the swipe speed of the first operation on the physical button touched in the first operation meet the second preset condition, the terminal presents the first interface on the display according to the swipe direction of the first operation on the physical button touched in the first operation. Optionally, the second preset condition includes a third threshold range that the swipe track corresponding to the first operation on the physical button should meet, a fourth threshold range that the swipe speed corresponding to the first operation on the physical button should meet, a preset physical button type that the physical button touched in the first operation should meet (the physical button type may be a physical home button, a physical back button, a physical volume button, and the like), and a fifth threshold range that the quantity of physical buttons touched in the first operation should meet (the fifth threshold range is generally greater than or equal to 1). Only after determining that the swipe track corresponding to the first operation on the physical button meets the third threshold range, the swipe speed corresponding to the first operation in the navigation area meets the fourth threshold range, the physical button touched in the first operation meets the preset physical button type, and the quantity of physical buttons touched in the first operation meets the fifth threshold range, the terminal presents the first interface on the display according to the swipe direction corresponding to the first operation on the physical button. 
     In addition, the third threshold range may be the same as or different from the first threshold range, and the fourth threshold range may be the same as or different from the second threshold range. 
     Optionally, when the first operation is pressing a physical button and simultaneously swiping from left to right by the user (when swiping is performed from left to right, another physical button needs to be touched), an effect diagram of the first interface presented by the terminal may be shown in  FIG. 12 . When the first operation is pressing a physical button and simultaneously swiping from right to left by the user (when swiping is performed from right to left, another physical button needs to be touched), an effect diagram of the first interface presented by the terminal may be shown in  FIG. 13 . When the first operation is any one of operations: swiping up and down in the navigation area by the user, pressing a virtual button in the navigation area and swiping up and back to the virtual button by the user, or pressing a virtual button in the navigation area and swiping down by the user, in combination with an operation of swiping left or right on the physical button by the user, the first interface presented by the terminal may be shown in  FIG. 10  or  FIG. 11 . 
     Based on the foregoing embodiment, in a third possible implementation manner of this embodiment of the present invention, this embodiment relates to a specific process in which the terminal presents the first interface on the display according to the double-tap event when the first touch event is the double-tap event. That is, the step S 102  specifically includes: the terminal presents the first interface on the display when determining that the type of the virtual button touched in the first operation matches a first preset type, and that the virtual button touched in the first operation is tapped twice in the first operation. 
     Specifically, the terminal receives the first operation input by the user, and the first operation is a tap operation performed by the user on the virtual button of the terminal, so that the terminal determines the double-tap event according to the tap operation. It should be noted that the terminal may determine the type of the tapped virtual button according to coordinates of a DOWN event involved in the tap operation, and may determine, according to a voltage or current status of a touchscreen at the coordinate location, the quantity of taps performed by the user on the virtual button. 
     Afterwards, the terminal determines whether the type of the virtual button touched in the first operation matches the first preset type. The first preset type may be any one or more virtual button types, for example, may be a virtual home button and virtual back button. Assuming that the terminal determines that the type of the virtual button touched in the first operation is the virtual home button, it indicates that the type of the virtual button touched in the first operation matches the first preset type, then the terminal further determines whether the virtual button touched in the first operation is tapped twice, and if the virtual button touched in the first operation is tapped twice, the terminal presents the first interface on the display. Optionally, when the terminal is a mobile phone, if the first operation is double-tapping a back button or double-tapping a multitasking button by the user, an effect diagram of the first interface presented by the terminal may be shown in  FIG. 14 . When the first operation is double-tapping the virtual button by the user, in combination with an operation of swiping left or right in the navigation area or on the physical button by the user, or pressing a virtual button in the navigation area and swiping left or right by the user, the first interface presented by the terminal may be shown in  FIG. 10  or  FIG. 11 . 
     Based on the foregoing embodiment, in a fourth possible implementation manner of this embodiment of the present invention, this embodiment relates to a specific process in which the terminal presents the first interface on the display according to the first touch-and-hold event when the first touch event is the first touch-and-hold event. That is, the step S 102  specifically includes: the terminal presents the first interface on the display when determining that the type of the virtual button touched in the first operation matches a second preset type, and that the contact duration of the first operation on the virtual button touched in the first operation meets first preset duration. 
     Specifically, the terminal receives the first operation input by the user, and the first operation is the touch-and-hold operation performed by the user on the virtual button of the terminal, so that the terminal determines the first touch-and-hold event according to the touch-and-hold operation. It should be noted that, the terminal may determine, according to coordinates of a DOWN event involved in the touch-and-hold operation, the type of the virtual button touched in the first operation, and may determine, according to voltage duration or current duration of a touchscreen at the coordinate location, the contact duration of the first operation on the virtual button touched in the first operation. 
     Afterwards, the terminal determines whether the type of the virtual button touched in the first operation matches the second preset type. The second preset type may be the same as or different from the first preset type. If the type of the virtual button touched in the first operation matches the second preset type, the terminal further determines whether the contact duration of the first operation on the virtual button touched in the first operation meets the first preset duration. If the contact duration of the first operation on the virtual button touched in the first operation meets the first preset duration, the terminal presents the first interface on the display. Optionally, the first preset duration may be preconfigured by the user by using software after factory delivery of the terminal, or the first preset duration may be loaded into a processor by using a fixture at factory delivery of the terminal. 
     Optionally, when the terminal is a mobile phone, if the first operation is touching and holding a back button or touching and holding a multitasking button by the user, an effect diagram of the first interface presented by the terminal may be shown in  FIG. 15 . When the first operation is touching and holding the virtual button, in combination with an operation of swiping left or right in the navigation area or on the physical button by the user, or pressing a virtual button in the navigation area and swiping left or right by the user, the first interface presented by the terminal may be shown in  FIG. 10  or  FIG. 11 . 
     According to the method for processing a user interface of a terminal provided in this embodiment of the present invention, a terminal may obtain a first touch event according to different first operations input by a user, and generate, according to the first touch event, a first interface that can be operated by the user with one hand. That is, according to the method provided in this embodiment, the user may trigger, by using different first operations in a navigation area of the terminal, the terminal to generate the first interface, that is, the method provided in this embodiment of the present invention diversifies a manner of triggering the terminal to generate the first interface, brings more possibilities to user experience, and improves intelligence of human-machine interaction. In addition, according to the method provided in this embodiment of the present invention, the user may trigger, by using different first operations not only in the navigation area but also on a virtual button or a substantive button, the terminal to generate the first interface, which further diversifies the manner of triggering the terminal to generate a one-handed operation interface, brings more possibilities to user experience, and further improves intelligence of human-machine interaction. 
       FIG. 16  is a schematic flowchart of Embodiment 2 of a method for processing a user interface of a terminal according to the present invention. This embodiment relates to a specific process in which a terminal adjusts a size of a first interface according to a second operation input by a user. Based on the foregoing embodiment, after the step S 102 , the method further includes the following steps. 
     S 201 : Obtain a second operation input by the user, and determine a second touch event corresponding to the second operation, where the second touch event includes at least one of: a third swipe event, in the navigation area of the terminal, that is collected by the terminal according to the second operation; a fourth swipe event, on the physical button of the terminal, that is collected by the terminal according to the second operation; a second touch-and-hold event, on the virtual button in the navigation area, that is collected by the terminal according to the second operation; or a fifth swipe event, in an adjustable area, that is collected by the terminal according to the second operation, where the adjustable area is an area on the display other than the first interface. 
     Specifically, for a manner in which the terminal obtains the second operation input by the user, refer to a specific process in which the terminal obtains the first operation input by the user in the step S 101 . For a process in which the terminal determines the second touch event according to the second operation, refer to a process in which the terminal determines the first touch event according to the first operation in the step S 101 . Details are not repeatedly described in this embodiment of the present invention. The fifth swipe event may be an event triggered by a swipe operation that is performed by the user in the area (that is, the adjustable area) on the display other than the first interface after the terminal presents the first interface on the display. 
     When the second operation is a swipe operation performed by the user in the virtual navigation area of the terminal, the second touch event determined by the terminal is the third swipe event. In the third swipe event, the terminal actually determines specific parameters in the third swipe event, and the parameters include a swipe track corresponding to the second operation in the navigation area, a swipe speed corresponding to the second operation in the navigation area, and a swipe direction corresponding to the second operation in the navigation area. 
     When the second operation is a swipe operation performed by the user on the physical button of the terminal, and the user touches at least one button in the swipe operation on the physical button, the second touch event determined by the terminal is the fourth swipe event. In the fourth swipe event, the terminal actually determines specific parameters in the fourth swipe event, and the parameters include a type of the physical button touched in the second operation, a quantity of physical buttons touched in the second operation, a swipe track of the second operation on the physical button touched in the second operation, a swipe speed of the second operation on the physical button touched in the second operation, and a swipe direction of the second operation on the physical button touched in the second operation. 
     When the second operation is a touch-and-hold operation performed by the user on the virtual button in the navigation area, the second touch event determined by the terminal is the second touch-and-hold event. In the second touch-and-hold event, the terminal actually determines specific parameters in the second touch-and-hold event, and the parameters include the type of the virtual button touched in the second operation, and contact duration of the second operation on the virtual button touched in the second operation. 
     When the second operation is a swipe operation performed by the user in the adjustable area corresponding to the second operation, the second touch event determined by the terminal is the fifth swipe event. In the fifth swipe event, the terminal actually determines specific parameters in the fifth swipe event, and the parameters include a swipe direction corresponding to the second operation in the adjustable area, and a swipe speed corresponding to the second operation in the adjustable area. 
     It should be noted that the second operation in this embodiment may the same as or different from the first operation. The third swipe event may the same as or different from the first swipe event, the fourth swipe event may the same as or different from the second swipe event, and the second touch-and-hold event may the same as or different from the first touch-and-hold event. 
     S 202 : Adjust the size of the first interface according to the second touch event. 
     Specifically, the size of the first interface may be adjusted according to the second touch event in the following several possible implementation manners. 
     In a first possible implementation manner, when the second touch event is the third swipe event, the terminal adjusts the size of the first interface according to the swipe track corresponding to the second operation in the navigation area and the swipe direction corresponding to the second operation in the navigation area, and controls, according to the swipe speed corresponding to the second operation in the navigation area, a speed of adjusting the size of the first interface. 
     Specifically, after the terminal presents the first interface, the terminal receives the second operation input by the user, and the second operation is the swipe operation performed by the user in the navigation area of the terminal, so that the terminal determines the third swipe event according to the swipe operation. It should be noted that, similar to the first swipe event or the second swipe event, the third swipe event may also include multiple independent events, and details are not repeatedly described herein. 
     The terminal may determine, according to a DOWN event and an UP event in the third swipe event, the swipe track (that is, a swipe distance) corresponding to the second operation in the navigation area. For example, the terminal may calculate, according to a difference between coordinates of the DOWN event and coordinates of the UP event, the swipe track corresponding to the second operation in the navigation area; or the terminal may determine, according to a DOWN event, MOVE events, and an UP event, the swipe track corresponding to the second operation in the navigation area (the third swipe event in this case includes multiple continuous MOVE events whose tracks are overlapped), and the swipe track in this case may be understood as total swipe displacement. In addition, the terminal may further obtain a time at which the DOWN event occurs and a time at which the UP event occurs in the third swipe event, to obtain, by means of calculation, a time consumed by the entire third swipe event; and then obtain, by means of calculation according to the total swipe track and the time consumed by the third swipe event, the swipe speed corresponding to the second operation in the navigation area. 
     After determining the swipe track corresponding to the second operation in the navigation area and the swipe speed corresponding to the second operation in the navigation area, the terminal adjusts the size of the first interface according to the swipe track corresponding to the second operation in the navigation area and the swipe direction corresponding to the second operation in the navigation area. The swipe track corresponding to the second operation in the navigation area determines an amount of adjusting the size of the first interface, the swipe direction corresponding to the second operation in the navigation area determines a direction of adjusting the size of the first interface, and the swipe speed corresponding to the second operation in the navigation area determines the speed of adjusting the size of the first interface. 
     Optionally, when the second operation performed by the user in the navigation area is swiping from left to right, if swipe distances are respectively A 1  and A 2 , a comparison diagram of effects of adjusting the first interface may be shown in  FIG. 17 . 
     In a second possible implementation manner, when the second touch event is the fourth swipe event, the terminal adjusts the size of the first interface according to the type of the physical button touched in the second operation, the quantity of physical buttons touched in the second operation, the swipe track of the second operation on the physical button touched in the second operation, and the swipe direction of the second operation on the physical button touched in the second operation, and controls, according to the swipe speed of the second operation on the physical button touched in the second operation, a speed of adjusting the size of the first interface. 
     Specifically, after the terminal presents the first interface, the terminal receives the second operation input by the user, and the second operation is the swipe operation performed by the user on the physical button of the terminal, so that the terminal determines the fourth swipe event according to the swipe operation. It should be noted that, similar to the third swipe event, the fourth swipe event may also include multiple independent events, and details are not repeatedly described herein. 
     The terminal may determine, according to a DOWN event and an UP event in the fourth swipe event, the swipe track (that is, a swipe distance) of the second operation on the physical button touched in the second operation, or may determine, according to a DOWN event, MOVE events, and an UP event, the swipe track corresponding to the second operation on the physical button. The terminal may further determine the swipe speed of the second operation on the physical button touched in the second operation. For a specific determining manner, refer to a specific process of determining the swipe track and the swipe speed that are corresponding to the second operation in the navigation area in the first possible implementation manner in the foregoing Embodiment 2, and details are not repeatedly described herein. At the same time, the terminal may further determine, according to coordinates of the DOWN event or the UP event or the MOVE events, the type of the physical button touched in the second operation and the quantity of physical buttons touched in the second operation. 
     Afterwards, the terminal adjusts the size of the first interface according to the type of the physical button touched in the second operation, the quantity of physical buttons touched in the second operation, the swipe track of the second operation on the physical button touched in the second operation, and the swipe direction of the second operation on the physical button touched in the second operation. The type of the physical button touched in the second operation and the quantity of physical buttons touched in the second operation determine whether the terminal adjusts the size of the first interface, the swipe track corresponding to the second operation on the physical button determines an amount of adjusting the size of the first interface, the swipe direction corresponding to the second operation on the physical button determines a direction of adjusting the size of the first interface, and the swipe speed corresponding to the second operation on the physical button determines the speed of adjusting the size of the first interface. 
     Optionally, when the second operation performed by the user on the physical button is swiping from left to right, if swipe distances are respectively A 1  and A 2 , a comparison diagram of effects of adjusting the first interface may be shown in  FIG. 17 . 
     In a third possible implementation manner: when the second touch event is the second touch-and-hold event, the terminal presents a first adjustable button in the first interface after determining that the type of the virtual button touched in the second operation matches a third preset type, and that the contact duration of the second operation on the virtual button touched in the second operation meets second preset duration. The first adjustable button is configured to provide, for the user, an interface to adjust the size of the first interface. 
     Specifically, after the terminal presents the first interface, the terminal receives the second operation input by the user, and the second operation is the touch-and-hold operation performed by the user on the virtual button of the terminal, so that the terminal determines the second touch-and-hold event according to the touch-and-hold operation. It should be noted that, the terminal may determine, according to coordinates of a DOWN event involved in the touch-and-hold operation, the type of the virtual button touched in the second operation, and may determine, according to voltage duration or current duration of a touchscreen at the coordinate location, the contact duration of the second operation on the virtual button touched in the second operation. 
     Afterwards, the terminal determines whether the type of the virtual button touched in the second operation matches the third preset type. The third preset type may be the same as or different from the first preset type. If the type of the virtual button touched in the second operation matches the third preset type, the terminal further determines whether the contact duration of the second operation on the virtual button touched in the second operation meets the second preset duration; if the contact duration of the second operation on the virtual button touched in the second operation meets the second preset duration, the terminal presents the first adjustable button in the first interface. The first adjustable button is configured to provide, for the user, the interface to adjust the size of the first interface, and the user adjusts the size of the first interface according to the first adjustable button. 
     Optionally, when the terminal is a mobile phone, if the second operation is touching and holding a back button or touching and holding a multitasking button or touching and holding a home button by the user, an effect diagram of the first interface and the first adjustable button that are presented by the terminal may be shown in  FIG. 18 . 
     In a fourth possible implementation manner: when the second touch event is the fifth swipe event, the terminal adjusts the size of the first interface according to the swipe direction corresponding to the second operation in the adjustable area, and controls, according to the swipe speed corresponding to the second operation in the adjustable area, a speed of adjusting the size of the first interface. 
     Specifically, after the terminal presents the first interface, the terminal receives the second operation input by the user, and the second operation is the swipe operation performed by the user in the adjustable area of the terminal, so that the terminal determines the fifth swipe event according to the swipe operation. It should be noted that, similar to the third swipe event or the fourth swipe event, the fifth swipe event may also include multiple independent events, and details are not repeatedly described herein. In addition, the swipe operation performed by the user in the adjustable area of the terminal may be performed by the user based on a boundary line of the first interface (that is, the size of the first interface is adjusted by dragging a boundary of the first interface), or the size of the first interface may be adjusted by swiping at another location of the adjustable area. For a manner in which the terminal determines the swipe speed corresponding to the second operation in the adjustable area, refer to the description in the foregoing embodiment, and details are not repeatedly described herein again. 
     Afterwards, the terminal adjusts the size of the first interface according to the swipe direction corresponding to the second operation in the adjustable area, and controls, according to the swipe speed corresponding to the second operation in the adjustable area, the speed of adjusting the size of the first interface. For example, as shown in  FIG. 19 , if the swipe direction corresponding to the second operation in the adjustable area is swiping up along a horizontal boundary line of the first interface, the first interface is stretched upwards, and a vertical length of the first interface is increased. As shown in  FIG. 20 , if the swipe direction corresponding to the second operation in the adjustable area is swiping left along a vertical boundary line of the first interface, the first interface is stretched leftwards, and a horizontal length of the first interface is increased. 
     According to the method for processing a user interface of a terminal provided in this embodiment of the present invention, a terminal may obtain a first touch event according to different first operations input by a user, and generate, according to the first touch event, a first interface that can be operated by the user with one hand. After presenting the first interface to the user, the terminal may further obtain a second touch event by using different second operations input by the user, and adjust a size of the first interface according to the second touch event. That is, according to the method provided in this embodiment, the terminal may be triggered, by using different first operations, to generate the first interface, and may further adjust the size of the first interface by using different second operations, which facilitates a one-handed operation performed by the user. Therefore, a manner of triggering the terminal to present a one-handed operation interface and a manner of adjusting the one-handed operation interface are diversified, more possibilities are brought to user experience, and intelligence of human-machine interaction is improved. 
       FIG. 21  is a schematic flowchart of Embodiment 3 of a method for processing a user interface of a terminal according to the present invention. This embodiment relates to a specific execution process in which the terminal adjusts a location of a first interface on a display after presenting the first interface. It should be noted that, this embodiment may be combined with the foregoing Embodiment 2, that is, location adjustment may be performed after the terminal adjusts a size of the first interface. In this embodiment, an example in which the terminal adjusts the location of the first interface on the display after presenting the first interface is used for description, that is, after the step S 102 , the method further includes the following steps. 
     S 301 : Obtain a third operation input by the user, and determine a third touch event corresponding to the third operation, where the third touch event includes a sixth swipe event, in the adjustable area, that is collected by the terminal according to the third operation, or a third touch-and-hold event, in the first interface, that is collected by the terminal according to the third operation. 
     Specifically, for a manner in which the terminal obtains the third operation input by the user, refer to a specific process in which the terminal obtains the first operation input by the user in the step S 101 , and for a process in which the terminal determines the third touch event according to the third operation, refer to a process in which the terminal determines the first touch event according to the first operation in the step S 101 . Details are not repeatedly described in this embodiment of the present invention. 
     When the third operation is a swipe operation performed by the user in the adjustable area of the terminal, the third touch event determined by the terminal is the sixth swipe event. In the sixth swipe event, the terminal actually determines specific parameters in the sixth swipe event, and the parameters include a swipe speed corresponding to the third operation in the adjustable area, a swipe starting point corresponding to the third operation in the adjustable area, and a swipe direction corresponding to the third operation in the adjustable area. 
     When the third operation is a touch-and-hold operation performed by the user in the first interface, the third touch event determined by the terminal is the third touch-and-hold event. In the third touch-and-hold event, the terminal actually determines a specific parameter in the third touch-and-hold event, and the parameter includes contact duration corresponding to the third operation in the first interface. 
     S 302 : Adjust the location of the first interface on the display according to the third touch event. 
     Specifically, the terminal may adjust the location of the first interface on the display according to the third touch event in the following two possible implementation manners. 
     In a first possible implementation manner, when the third touch event is the sixth swipe event, the terminal adjusts the location of the first interface on the display according to the swipe starting point corresponding to the third operation in the adjustable area and the swipe direction corresponding to the third operation in the adjustable area, and controls, according to the swipe speed corresponding to the third operation in the adjustable area, a speed of adjusting the location of the first interface. 
     Specifically, after the terminal presents the first interface, the terminal receives the third operation input by the user, and the third operation is the swipe operation performed by the user in the adjustable area of the terminal, so that the terminal determines the sixth swipe event according to the swipe operation. It should be noted that, similar to the fifth swipe event, the sixth swipe event may also include multiple independent events, and details are not repeatedly described herein. In addition, the swipe operation performed by the user in the adjustable area of the terminal may be performed by the user based on an intersection of a horizontal boundary line and a vertical boundary line of the first interface (that is, the swipe starting point corresponding to the third operation in the adjustable area). The swipe starting point may be generally a point at an upper left corner of the first interface. In addition, for a manner in which the terminal determines the swipe speed corresponding to the third operation in the adjustable area, refer to description in the foregoing embodiment, and details are not repeatedly described herein. 
     Afterwards, the terminal adjusts the location of the first interface on the display according to the swipe direction and the swipe starting point that are corresponding to the third operation in the adjustable area, and controls, according to the swipe speed corresponding to the third operation in the adjustable area, the speed of adjusting the location of the first interface. For example, as shown in  FIG. 22 , if the swipe direction corresponding to the third operation in the adjustable area is swiping left from the point at the upper left corner, the first interface moves leftwards. 
     In a second possible implementation manner: when the third touch event is the third touch-and-hold event, the terminal presents a second adjustable button in the first interface after the contact duration corresponding to the third operation in the first interface meets third preset duration. The second adjustable button is configured to provide, for the user, an interface to adjust the location of the first interface on the display. 
     Specifically, after the terminal presents the first interface, the terminal receives the third operation input by the user, and the third operation is the touch-and-hold operation performed by the user in the first interface, so that the terminal determines the third touch-and-hold event according to the touch-and-hold operation. It should be noted that the terminal may determine the contact duration of the third operation in the first interface according to coordinates of a DOWN event involved in the touch-and-hold operation and voltage duration or current duration of a touchscreen at the coordinate location. 
     Afterwards, the terminal presents the second adjustable button in the first interface after determining that the contact duration corresponding to the third operation in the first interface meets the third preset duration. The second adjustable button is configured to provide, for the user, the interface to adjust the location of the first interface on the display. The user adjusts the location of the first interface on the display according to the second adjustable button. For example, optionally, when the terminal is a mobile phone, if the third operation is touching and holding the first interface by the user, the second adjustable button presented by the terminal may be shown in  FIG. 23 , and the user may press the second adjustable button to adjust the location of the first interface on the display. 
     It should be noted that, when adjusting the location of the first interface on the display, the terminal needs to determine coordinates of the location of the first interface on the display after presenting the first interface. When the user inputs the third operation, a process in which the terminal determines the third touch event according to the third operation is actually also a process of calculating coordinates of a location of the moved first interface caused by the third operation of the user. Therefore, the terminal converts the third operation into coordinates of a new location of the first interface, so as to change the location of the first interface. For example, if original (left, top) coordinates of an upper left corner of the first interface are (left1, top1), and the terminal determines, according to the third operation of the user, that new coordinates of the upper left corner of the first interface are (left2, top2), the terminal may control a new presentation location of the first interface on the display according to (left2, top2). 
     In addition, when the user operates interface elements of the first interface in the first interface, event coordinates transmitted from a drive layer (an underlying layer) to an application layer (an upper layer) of a terminal system are still based on an original interface (that is, a large-screen interface). To ensure that an event corresponding to an operation performed by the user in the first interface can receive a correct response, the terminal needs to perform coordinate mapping for the event reported by the system. First, the terminal determines, according to coordinates of the event corresponding to the operation performed by the user in the first interface and a coordinate range corresponding to the first interface, whether the current operation performed by the user is in the first interface (mapping is not performed for an event outside of the first interface). Second, if the event corresponding to the current operation performed by the user is an event in the first interface, the terminal first records coordinates (X, Y) of the original event reported by the underlying layer of the terminal. The coordinates are actually coordinates of an actual location that are based on an original interface; then the terminal performs vector addition calculation on the coordinates (X, Y) and coordinates (left, top) in the first interface, to map the coordinates (X, Y) to coordinates (X1, Y1) that are based on the first interface. Finally, according to a horizontal scale and a vertical scale of the first interface, the coordinates (X1, Y1) that are based on the first interface is proportionally scaled up to coordinates (X2, Y2) that are based on the original large-screen interface, and the coordinates (X2, Y2) are finally sent to a corresponding processing module for processing. For example, after the terminal generates the first interface, the user taps an interface element, of the first interface, that is located at the center of the first interface. The tap operation is coordinates (X, Y) of a lower-left location of an original interface, but is coordinates (X1, Y1) of a center location of the first interface. Therefore, the underlying layer of the terminal reports the coordinates (X, Y) of the lower-left location to the upper layer, and the terminal obtains the location (X1, Y1) of the tap operation for the first interface according to coordinate mapping. Because the tap operation is performed at the center location for the first interface, a response should be an element of the first interface at a center location of the original interface. Therefore, the coordinates (X1, Y1) need to be mapped to coordinates (X2, Y2) of the center location of the original interface, so that the application layer of the terminal correctly responds to the tap operation. 
     According to the method for processing a user interface of a terminal provided in this embodiment of the present invention, a terminal may obtain a first touch event according to different first operations input by a user, and generate, according to the first touch event, a first interface that can be operated by the user with one hand. After presenting the first interface to the user, the terminal may further obtain a third touch event by using different third operations input by the user, and adjust a location of the first interface on a display according to the third touch event. That is, according to the method provided in this embodiment, the terminal may be triggered, by using different first operations, to generate the first interface, and may further adjust the location of the first interface on the display by using different third operations. Therefore, a manner of triggering the terminal to present a one-handed operation interface and a manner of adjusting the one-handed operation interface are diversified, more possibilities are brought to user experience, and intelligence of human-machine interaction is improved. 
     An embodiment of the present invention provides a user interface of a terminal. The terminal includes a physical button, a display, a memory, multiple application programs, and one or more processors that are configured to execute one or more programs stored in the memory, where the display includes a touch-sensitive surface and a display. The user interface includes a second interface for displaying interface elements of the second interface, and a first interface for displaying elements of the first interface and for a user to operate with one hand, where the first interface is a scaled-down second interface, content of the elements of the first interface is the same as content of the interface elements of the second interface, and sizes of the interface elements of the first interface is sizes of the elements of the scaled-down second interface; where 
     the second interface for displaying the interface elements of the second interface includes: 
     displaying the second interface on the display, where the second interface includes the interface elements of the second interface and a navigation area of the touch-sensitive surface; 
     after a first operation is detected in the navigation area of the touch-sensitive surface or on the physical button, and a first touch event corresponding to the first operation is determined, responding to the first touch event, where the first touch event includes at least one of: a first swipe event, in the navigation area of the terminal, that is collected by the terminal according to the first operation; a second swipe event, on the physical button of the terminal, that is collected by the terminal according to the first operation; a double-tap event, on a virtual button in the navigation area, that is collected by the terminal according to the first operation; or a first touch-and-hold event, on the virtual button in the navigation area, that is collected by the terminal according to the first operation; and 
     displaying the first interface on the display, where the first interface includes the interface elements of the first interface and a scaled-down navigation area.
