 FIG. 1 is a schematic diagram showing an exemplary hardware structure of a terminal 100 according to an embodiment of the present invention. The terminal 100 shown in Fig. 1 may be a mobile terminal such as, but not limited to, a mobile phone (e.g., a smart phone), a tablet, a personal digital assistant (PDA), an audio player, and the like. As shown in FIG. 1, terminal 100 includes a processor 102, a memory 104, a touch screen 106, a communication interface 108, and a bus 110. The processor 102, the memory 104, the touch screen 106, and the communication interface 108 are communicatively coupled by a bus 110.

 The processor 102 can use a general-purpose central processing unit (CPU), a processor, an application specific integrated circuit (ASIC), or one or more integrated circuits for executing related programs, The technical solution provided by the embodiment of the present invention is implemented.

 The memory 104 may be a read only memory (ROM), a static storage device, a dynamic storage device, or a random access memory (RAM). The memory 104 can store an operating system and other applications. When the technical solution provided by the embodiment of the present invention is implemented by software or firmware, the program code for implementing the technical solution provided by the embodiment of the present invention is stored in the memory 104 and executed by the processor 102.

 The touch screen 106 is both an input device and an output device. As an input device, the touch screen 106 can receive data and information that the user inputs by touch. In order to facilitate user input of information and display of richer content, the size of the touch screen 106 configured by the terminal 100 is usually large. By touching the touch screen 106, the user can input information such as text and commands, thereby using various functions provided by the terminal 100, such as, but not limited to, making a call, sending a short message, playing a music video, playing a game, and the like. As an output device, the touch screen 106 can display information such as an operation result to the user. It should be noted that in a specific implementation process, the terminal 100 may further include other input and output devices not shown in Fig. 1, such as but not limited to a speaker or the like.

Communication interface 108 implements the terminal using transceivers such as, but not limited to, transceivers 100 Communication with other devices or communication networks such as, but not limited to, Ethernet, Radio Access Network (RAN), Wireless Local Area Network (WLAN), etc.

 Bus 110 may include a path for communicating information between various components of terminal 100, such as processor 102, memory 104, touch screen 106, and communication interface 108.

 By configuring more powerful devices such as, but not limited to, the more powerful processor 102, memory 104, touch screen 106, communication interface 108, and bus 110, the terminal 100 can implement multitasking, ie, at the same time, on the mobile Run multiple tasks on the terminal. Among the plurality of tasks running simultaneously, a task that is being presented to the user through the current display interface of the touch screen 106 and that may need to interact with the user is referred to as a foreground task, and other tasks in a suspended state are referred to as a background task. Background tasks often do not need to interact with the user, nor do they need to present information to the user, so they are usually executed without disturbing the user's other work. Through task switching, the back-end tasks can be switched to the foreground, and the foreground tasks before switching are switched to the background. For example, a user's terminal runs multiple tasks simultaneously, including download tasks, email tasks, and video game tasks. The user is currently playing an electronic game corresponding to the electronic game task, and the game process is displayed to the user through the current display interface of the touch screen. In this case, the video game task is the foreground task, and other tasks such as download tasks and email sending and receiving tasks are background tasks.

 It should be noted that although the terminal 100 shown in FIG. 1 only shows the processor 102, the memory 104, the touch screen 106, the communication interface 108, and the bus 110, in a specific implementation process, those skilled in the art should understand that the terminal 100 also Contains other devices necessary to achieve proper operation. Meanwhile, according to specific needs, those skilled in the art should understand that the mobile terminal 100 may also include hardware devices that implement other functions.

2 is an exemplary flow diagram of a task switching method 200 in accordance with an embodiment of the present invention. The task switching method 200 shown in FIG. 2 is applied to a terminal (such as but not limited to a mobile terminal), the terminal is configured with a touch screen, and at least one background task runs on the terminal. Step 202: Display a task bar on a current display interface of the touch screen, and display a task icon of the at least one background task in the task bar.

 In the specific implementation process, the above task bar can be displayed on the current display interface of the terminal touch screen. In addition, the operation of touching the current display interface of the touch screen can also be detected in real time, and when the operation of touching the current display interface of the touch screen is detected, the task bar is displayed on the current display interface. In the case of the latter method, in order to prevent the displayed task bar from obstructing the user from viewing the main content being displayed on the current display interface (for example, but not limited to a game screen, a video screen, etc.), after displaying the above taskbar If no operation on the terminal is detected within a preset display duration, the display of the above task bar may also be cancelled. In the specific implementation process, the display timing of the above task bar can be set according to specific needs.

 In addition, the above task bar can be displayed at any position on the current display interface of the terminal, such as the top, bottom or side of the current display interface. In the specific implementation process, the display position of the task bar can be set according to specific needs. When the taskbar is set at the top of the current display interface, the current display interface can be as shown in Figure 3A. The current display interface 300 shown in FIG. 3A includes a task bar 302. The task bar 302 contains task icons 302, 304, and 306 corresponding to three background tasks.

 Due to the size of the touch screen of the terminal, the number of task icons of the background tasks that can be displayed on the taskbar is limited. In this case, it is also possible to display only a part of the task icon of the background task, and then display a preset special icon. In this case, when an operation of touching the preset special icon is detected, a task list is popped up, and a task icon whose task icon fails to be displayed in all the background tasks in the task bar is displayed in the task list, For users to choose further.

At the same time, due to the size of the touch screen of the terminal, the display area of the taskbar itself may be small, which makes the task icon displayed in the taskbar small. In this case, in order to facilitate the user's choice, an enlarged display scheme can be used, which specifically includes: Step A: detecting a long-time touch operation for the task bar, wherein the long-time touch operation is a touch operation in which the touch duration exceeds a preset touch duration threshold.

 Step B, when the long-time touch operation is detected, calculating an area to be enlarged according to the touch position corresponding to the long-time touch operation, wherein the area to be enlarged is a part of the task bar, and the touch The location is within the area to be enlarged.

 Step C, displaying an enlarged display window, and displaying the area to be enlarged by the enlarged display window.

 It is not difficult to understand that, in a specific implementation process, the above enlarged display scheme can be applied after step 202 of method 200, before step 204.

 In addition, various methods may be used to calculate the above-mentioned area to be enlarged, for example, a circular area having a touch position as a center and a radius of a predetermined radius length as the above-mentioned area to be enlarged. In a specific implementation process, the preset radius length may be set according to specific needs (such as, but not limited to, a terminal touch screen size). Further, a square area centering on the above-described touch position and having a side length of the preset side length may be used as the above-mentioned area to be enlarged. In a specific implementation process, the preset side length may be set according to specific needs, such as but not limited to a terminal touch screen size. Further, a rectangular area centering on the above-described touch position, a long side using a preset long side length, and a short side using a preset short side length may be used as the above-mentioned area to be enlarged. In a specific implementation process, the preset long side length and the preset short side length may be set according to specific needs (such as, but not limited to, a terminal touch screen size). It should be noted that those skilled in the art should understand that the calculation method of the area to be enlarged provided by the embodiment of the present invention is not limited to the above method, and other methods may be used to calculate the area to be amplified i or .

FIG. 3B shows the current display interface 300' after the above enlarged display scheme is applied. As shown in FIG. 3B, when the user's touch duration for the position around the task icon 304 in the taskbar (the touch position is within the taskbar) exceeds the preset touch duration threshold, an enlarged display window 308 is displayed. The area to be enlarged calculated according to the current touch position is enlargedly displayed in the enlarged display window 308. Step 204: Detect a preset drag operation for a task icon in the taskbar.

 When the above enlarged display scheme is used, step 204 may specifically detect a preset drag operation for a task icon in the area to be enlarged displayed in the enlarged display window.

 In a specific implementation process, the preset drag operation is an operation of dragging the task icon to a preset position on the current display interface. In addition, the preset drag operation may also be an operation of dragging the task icon by a preset distance. In addition, the preset drag operation may also be an operation of dragging the task icon along a preset path.

In addition, the preset drag operation may also be an operation of dragging the task icon by a preset distance along a preset path. In the specific implementation process, the specific implementation mode of the preset drag operation can be selected according to specific needs.

 Step 206: When the preset drag operation is detected, switch the background task corresponding to the task icon pointed by the preset drag operation to the foreground. Specifically, after the background task corresponding to the task icon for the preset drag operation is switched to the foreground, the background task corresponding to the task icon for the preset drag operation is converted into the foreground task, and the terminal touch screen is The current display interface will display the task screen of the background task corresponding to the task icon for which the preset drag operation is directed.

 Specifically, the above-mentioned enlarged display scheme is used, and the step 204 is specifically implemented to detect a preset drag operation for a task icon in the area to be enlarged displayed in the enlarged display window, and the preset drag and drop When the operation is to drag the task icon to a preset position on the current display interface (for example, the position indicated by the dashed line 310), as shown in FIG. 3B, it is detected that the task icon 304 in the enlarged display window 308 is When dragged to the position shown by the dashed line 310, the background task corresponding to the task icon 304 will be switched to the foreground.
