It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure.

The accompanying drawings referred to in the specification are a part of this disclosure, and provide illustrative embodiments consistent with the disclosure and, together with the detailed description, serve to illustrate some embodiments of the disclosure.

Various embodiments of the present disclosure are described below with specific examples, and other advantages and effects of the present disclosure can be easily understood by those skilled in the field of technology from the contents disclosed in this specification. The following description refers to the accompanying drawings in which same numeral references in different drawings may represent the same or similar elements unless otherwise indicated.

The inventors of the present disclosure have recognized that, in an existing technology, there is only one fully displayed preview interface corresponding to an application program in the task management interface, and the user can merely view and manage the application program corresponding to the above-mentioned fully displayed preview interface. If the user wants to view and manage other running application programs, he/she needs to perform a sliding operation in the task management interface, the process of which is inefficient and inconvenient.

Various embodiments of the present disclosure provide a method for displaying a task management interface, and a device based thereupon. In some embodiments of the present disclosure, the preview interfaces corresponding to a plurality of running application programs are arranged in a lattice in the task management interface. The respective preview interfaces do not overlap with each other, such that the user may view the preview interfaces corresponding to a plurality of application programs simultaneously. In addition, no other operations are required when the user manages the application programs corresponding to preview interfaces displayed in the task management interface, thereby improving the operation efficiency and convenience.

In a method according to some embodiments of the present disclosure, various steps may be executed by a mobile terminal, such as a mobile phone, a tablet computer, an e-book reader, a multimedia player, a Personal Digital Assistant (PDA), a wearable device, etc..

<FIG> is a flow chart illustrating a method for operating a task management interface, according to some embodiments of the present disclosure. The method is applied in the mobile terminal, and includes the following steps.

In step <NUM>, a first trigger signal for triggering display of the task management interface is received.

The task management interface is a display interface of a task manager, and generally displays a preview interface corresponding to the running application program in the mobile terminal, such that the user may view and manage the running application program in the mobile terminal. The first trigger signal, which is generally triggered by a user, is used for triggering the mobile terminal to display the task management interface.

In some implementations, the first trigger signal is a signal of a sliding operation with a sliding speed less than a preset speed. When the user performs a sliding operation in the current display interface in the mobile terminal, if the mobile terminal detects that the speed corresponding to the sliding operation triggered by the user is less than the preset speed, the mobile terminal receives the first trigger signal for triggering the display of the task management interface. The speed corresponding to the sliding operation is the ratio of the trace length of the sliding operation to the action time of the sliding operation. The preset speed may be set based on actual needs, which is not limited in the embodiments of the present disclosure. In an example, the preset speed is <NUM> centimeters per second (cm/s).

In some other implementations, the first trigger signal is a signal of a sliding operation which stays longer than a preset time at the end position. When the user performs a sliding operation in the current display interface in the mobile terminal, if the mobile terminal detects that the sliding operation triggered by the user stays longer than the preset time at the end position, the mobile terminal receives the first trigger signal for triggering the display of the task management interface. The preset time may be set based on actual needs, which is not limited in the embodiments of the present disclosure. In an example, the preset time is <NUM> seconds.

It should be noted that the above first trigger signal is exemplary and explanatory only, and may be preset based on actual needs, which is not limited in the embodiments of the present disclosure.

In step <NUM>, n application program running in the mobile terminal are acquired triggered by the first trigger signal, where n is an integer greater than <NUM>.

A running application program includes an application program running in a foreground and an application program running in a background. The application program running in the foreground of the mobile terminal refers to the application program displays a user interface directly in the current display interface of the mobile terminal. The application program running in the background of the mobile terminal refers to the application program does not display a user interface in the current display interface of the mobile terminal and is still in a running state.

In step <NUM>, the preview interface corresponding to each application program is acquired.

The preview interface corresponding to the application program may be a preview of the current display interface in the application program, and may also be a preset preview associated with the application program.

When the preview interface corresponding to the application program is the preview of the current display interface of the application program, acquiring the preview interface corresponding to the application program may include the following possible implementations.

In a first possible implementation, the current display interface of the application program is scaled down from a first size to a second size, to generate the preview interface corresponding to the application program.

The first size is the size of the current display interface of the application program, which may either be the size equal to the size of the screen of the mobile terminal, or the size slightly smaller than the size of the screen of the mobile terminal. The second size is the size of the preview interface corresponding to the application program. The second size is smaller than the first size. In some embodiments, after obtaining the current display interface of the application program, the mobile terminal needs to scale down the above current display interface in equal proportion (including scaling down the whole current display interface and the respective elements, e.g. icons, included in the current display interface in equal proportion), to obtain the current display interface of a second size, namely the preview interface corresponding to the application program.

In a second possible implementation, a display area of a third size is clipped from the current display interface of the application program. The display area of the third size is scaled down to a fourth size, to generate the preview interface corresponding to the application program.

Different from the first possible implementation, in the second possible implementation, the preview interface corresponding the application program is acquired based upon a partial interface of the current display interface of the application program. Here, the third size is the size of the partial interface of the current display interface of the application program. In some embodiments, the third size is half of the first size. The fourth size is the size of the preview interface corresponding to the application program. In some embodiments, the fourth size is half of the second size. In this implementation, the mobile terminal first clips the current display interface of the application program to obtain a partial interface of the current display interface of the application program, then scales down the partial interface of the current display interface of the application program in equal proportion, to obtain the preview interface corresponding to the application program.

In a third possible implementation, the current display interface of the application program is scaled down from the first size to the second size. The display area of the fourth size is clipped from the scaled current display interface of the application program, to generate the preview interface corresponding to the application program.

Different from the first possible implementation, in the third possible implementation, the preview interface corresponding to the application program is acquired based upon a partial interface of the current display interface of the application program. In this implementation, the mobile terminal first scales down the current display interface of the application program in equal proportion, to obtain a scaled current display interface, and then clips the scaled-down current display interface, to obtain the preview interface corresponding to the application program. Here, the second size is the size of the scaled current display interface, and the fourth size is the size of the preview interface corresponding to the application program. The fourth size is smaller than the second size.

When the preview interface corresponding to the application program is the preset preview of an interface associated with the application program, a preset correspondence relation between the application program and the preview interface is stored in the mobile terminal. After acquiring the running application program, the mobile terminal looks up the above preset correspondence relation, to obtain the preview interface corresponding to the application program.

In step <NUM>, the task management interface including the preview interfaces respectively corresponding to the n application programs which are arranged in a lattice is received.

The preview interfaces respectively corresponding to the n application programs do not overlap with each other in the task management interface. In addition, the task management interface further includes identifications of the above n application programs, such as icons and names of the application program.

In some embodiments, the task management interface is divided into m columns, and the preview interfaces corresponding to the application programs are sequentially arranged in each column, where m is an integer greater than <NUM>, and m is <NUM> in some embodiments. The above arrangement manner may be termed a longitudinal waterfall arrangement. In combination with <FIG>, it shows a schematic diagram of a task management interface <NUM> in some embodiments. The task management interface <NUM> includes a preview interface <NUM> respectively corresponding to <NUM> application programs.

Because the size of the preview interface corresponding to the application program is smaller than the size of the task management interface, the task management interface may generally directly display the preview interfaces corresponding to a plurality of application programs. Moreover, when a large number of application programs are running, the task management interface only displays the preview interfaces corresponding to partial application programs, and the user may trigger the task management interface by a sliding operation to display the preview interfaces corresponding to the remaining application programs.

In some embodiments, the task management interface may include a preferred preview interface arranged at the frontmost of the task management interface. Exemplarily, the preferred preview interface is positioned at the upper left corner of the task management interface.

In a first example, the preferred preview interface is a preview interface corresponding to the application program running in the foreground. In a second example, the preferred preview interface is a preview interface corresponding to a music application program. In a third example, the preferred preview interface displays system function options. As there are usually many system function options, the preferred preview interface only displays part of the system function options. Therefore, an extension operation control, which may be a triangle, may be set in the preferred preview interface, and all the system function options are displayed in the terminal after the user triggers the extension operation control.

In combination with <FIG>, it shows an interface diagram of a preferred preview interface <NUM> in some embodiments. The preferred preview interface <NUM> is a preview interface corresponding to the music application program. In combination with <FIG>, it shows an interface diagram of a preferred preview interface <NUM> in some embodiments. The preferred preview interface <NUM> includes a system function option <NUM> and an extension operation control <NUM>.

In some embodiments, prior to step <NUM>, the mobile terminal may predetermine the display position of the preview interface corresponding to the application program in the task management interface. The following embodiments illustrate three possible implementations for determining the display position.

In a first possible implementation, the mobile terminal, according to the last running moments in the foreground respectively corresponding to the n application programs, determines the display positions of the preview interfaces respectively corresponding to the n applications in the task management interface.

The last running moment corresponding to the application program in the foreground refers to the time point when the application program runs in the foreground and the time interval between which and the current time point is the smallest. In some embodiments, the less the time interval between the last running moment corresponding to the application program in the foreground and the current time point is, the more forward the display position of the preview interface corresponding to the application program is in the task management interface. The greater the time interval between the last running moment for the application program in the foreground and the current time point is, the more backward the display position of the preview interface corresponding to the application program is in the task management interface. In a specific example, the display position of the preview interface corresponding to the application program which is running in the foreground is at the frontmost of the task management interface before the mobile terminal displays the task management interface.

In a second possible implementation, the mobile terminal, according to the frequency of usage respectively corresponding to the n application programs determines the display positions of the preview interfaces respectively corresponding to the n application programs in the task management interface.

The frequency of usage corresponding to the application program refers to the frequency and number of times the user uses the application program. In some embodiments, the higher the frequency of usage corresponding to the application program, the more forward the display position of the preview interface corresponding to the application program is in the task management interface. The lower the frequency of usage corresponding to the application program, the more backward the display position of the preview interface corresponding to the application program is in the task management interface.

In a third possible implementation, the mobile terminal, according to the correlation among n application programs, determines the display positions of the preview interfaces respectively corresponding to the n application programs in the task management interface.

The correlation between two application programs may be measured by the number of times of the simultaneous running of the above two application programs. The more the number of times of simultaneous running of the two application programs, the higher correlation between the above two application programs. The less the number of times of simultaneous running of the two application programs, the lower the correlation between the two application programs. In some embodiments, the higher the correlation between the two application programs, the closer the distance between the preview interfaces corresponding to the above respective two application programs displayed in the task management interface. The lower correlation between the two application programs, the further the distance between the display positions of the preview interfaces respectively corresponding to the above two application programs in the task management interface. In a specific example, the mobile terminal displays the preview interface corresponding to the application program running in the foreground at the most front of the task management interface before the mobile terminal displays the task management interface, then determines, according to the correlation between other application programs and the application program corresponding to the preview interface displayed at the frontmost, the display positions of the preview interfaces corresponding to other application programs in the task management interface t.

Therefore, in the method in the embodiments of the present disclosure, the preview interfaces corresponding to a plurality of running application programs are arranged in a lattice in the task management interface, such that the respective preview interfaces do not overlap with each other, and the user may simultaneously view the preview interfaces corresponding to a plurality of application programs. In addition, no other operations are required when the user manages the application program corresponding to preview interfaces displayed in the task management interface, thereby improving the operation efficiency and convenience.

After the mobile terminal displays the preview interface of the running application program in the task management interface, the user may manage the above running application program in the task management interface. For example, the user can trigger the application program to run in the foreground, trigger the application program to stop running and so forth. Based on the alternative embodiment of the embodiments shown in <FIG>, the method for displaying the task management interface may further include the following steps.

In step S201, a signal of a drag operation having a start position of which is positioned in the preview interface corresponding to a first application program in the task management interface and an end position of which is positioned in the preview interface corresponding to a second application program in the task management interface is received.

In step S202, the first application program and the second application program are switched to run in the foreground triggered by the signal of the drag operation, and the display interfaces of the first and second application programs are displayed in a split-screen.

When the user wish to run two application programs in the foreground simultaneously, and would like that the above application programs running in the foreground simultaneously can be displayed in a split-screen in the current display interface of the mobile terminal, the user may drag the preview interface of one application program to the preview interface of the other application program in the task management interface, and then the mobile terminal exits the task management interface triggered by the signal of the drag operation of the user and the display interfaces of the above two application programs are respectively displayed in a split-screen in the current display interface.

In combination with <FIG>, it shows a schematic diagram of an interface of a split-screen of some embodiments of the present disclosure. The task management interface <NUM> includes the preview interfaces <NUM> corresponding to a plurality of running application programs. When user drags the preview interface <NUM> corresponding to an application program to the preview interface <NUM> corresponding to another application program, the terminal exits the task management interface <NUM>, and displays a user interface <NUM> of the above two application programs in the current display interface <NUM>.

In some embodiments, the method in the embodiments of the present disclosure may further include the following steps.

When receiving a first operation signal for a preview interface corresponding to any application program in the task management interface, the mobile terminal switches the application program to run in the foreground triggered by the first operation signal. The first operation signal may be any of a click operation signal, a long press operation signal, and a sliding operation signal.

When receiving a second operation signal for the preview interface corresponding to any application program in the task management interface, the mobile terminal stops running the application program according to the second operation signal. The second operation signal may be any of a click operation signal, a long press operation signal, and a sliding operation signal.

When receiving a third operation signal for the preview interface corresponding to any application program in the task management interface, the mobile terminal displays a menu option box at the upper layer of the preview interface corresponding to the application program triggered by the third operation signal. The menu option box includes respective menu options corresponding to the application program. For instance, the menu option may include the third operation signal which may be any of a click operation signal, a long press operation signal, and a sliding operation signal.

It should be noted that the first operation signal and the second operation signal differ from the third operation signal.

Therefore, according to the method in the embodiments of the present disclosure, the mobile terminal may display in a split-screen by the drag operation signal triggered by the user. Moreover, the function for managing respective running application programs is also provided.

The user may conduct a unified management on the application programs corresponding to all the preview interfaces displayed in the task management interface. For example, the user may trigger all the running application programs to stop running. Based on the alternative embodiment of the embodiment shown in <FIG>, the upper layer of the task management interface also displays a delete operation control, and the method for displaying the task management interface may further include the following steps.

In step S301, a second trigger signal corresponding to a delete operation control is received.

In step S302, n application programs triggered by the second trigger signal are stopped running triggered by the second trigger signal.

The delete operation control is used to stop running all the running application programs such that the user can conduct a unified management on all the running application programs. In combination with <FIG>, it shows a schematic diagram of an interface when the delete operation control is triggered of some embodiments of the present disclosure. The task management interface <NUM> includes the preview interfaces <NUM> corresponding to a plurality of application programs. An upper of the task management interface <NUM> displays a delete operation control <NUM>. After the user clicks the delete operation control <NUM>, all the running application programs in the terminal stop running. Here, the preview interfaces corresponding to all the application programs are deleted from the task management interface <NUM>.

In addition, since the user only needs to trigger the delete operation control once to stop running all the running application program, compared with the related art where the preview interface displayed in the task management interface needs to be triggered so as to stop running the corresponding application program, the embodiments of the present disclosure can improve the operation efficiency of the user efficiently.

The user may also rapidly open the application program that is not running in the mobile terminal without exiting the task management interface. Based on the alternative embodiment of the embodiment shown in <FIG>, the method for displaying the task management interface may further include the following steps.

In step <NUM>, an application program list is displayed when a signal of a first sliding operation in a preset area in the task management interface is received.

The preset area may be a blank area in the task management interface, namely, an area where no preview interface is displayed in the task management interface. The preset area may be at the periphery of the task management interface, such as the upper layer, the lower layer, the left side, the right side and so on, which is not limited in the embodiments of the present disclosure.

The application program list includes application programs installed in the mobile terminal. The application program list may include identifications of the application program installed in the mobile terminal. The identification of the application program is used to uniquely identify the application program. The identification of the application program may be an icon, or a name, etc., which is not limited in the embodiments of the present disclosure. In addition, due to the limited size of the display interface of the mobile terminal, the mobile terminal only displays the identifications of part of the application programs, and the user may, by means of a sliding operation, enable the mobile terminal to display identifications of other application programs in addition to the above part of application programs.

Further, after the application program list is displayed, if the user performs a sliding operation with a direction opposite to the direction of the first sliding operation, on the application program list, the mobile terminal redisplays the task management interface.

By way of the above manner, the user can rapidly open other application programs that are not running in the mobile terminal without exiting the task management interface.

In step <NUM>, a system function interface is displayed when a signal of a second sliding operation in a preset area in the task management interface is received.

The system function interface includes a system function option. Further, after the system function interface is displayed, if the user performs a sliding operation with a direction opposite to the direction of the second sliding operation, on the system function interface, the mobile terminal redisplays the task management interface. In combination with <FIG>, it shows a schematic diagram of an interface where a system function interface <NUM> is displayed according to some embodiments of the present disclosure. The task management interface <NUM> includes the preview interfaces <NUM> corresponding to a plurality of application programs. When the area where no preview interface is displayed in the task management interface acquires a left-to-right sliding operation by the user, the terminal displays the system function interface <NUM> which includes a system function option <NUM> and an extension operation control <NUM>.

It should be noted that the first sliding operation and the second sliding operation have different sliding directions. Further, the sliding directions of the two sliding operations may be determined according to the actual position of the preset area in the task management interface.

For example, where the preset area is at an upper layer or lower layer of the task management interface, the first sliding operation has a left-to-right sliding direction, and the second sliding operation has a right-to-left sliding direction, or vice versa. For another example, when the preset area is at the left side or the right side of the task management interface, the first sliding operation has a top-to-bottom sliding direction, and the second sliding operation has a bottom-to-top sliding direction, or vice versa. By way of the above manner, the area where the user may perform the sliding operation in the task management interface may be broadened, to facilitate the user's operation.

As such, according to the method of the embodiments of the present disclosure, by providing the delete operation control, the function of stopping running all the running application programs simultaneously is extended for the mobile terminal. Further, the user only needs to trigger the above delete operation control once to stop running all running application programs. Thus, with the situation where the user needs to trigger the preview interface of each running application program to stop the above application program is avoided, and operation efficiency is improved.

Additionally, the application program list or the system function interface can be displayed by acquiring the user's sliding operation on the preset area in the task management interface. In one aspect, the user can rapidly open the other application programs that are not running in the mobile terminal without exiting the task management interface. In another aspect, the user can manage the system function option conveniently without exiting the task management interface.
