In order to better understand the embodiments of the present application, a system architecture applicable to the embodiments of the present application is described below.

Referring to FIG. 3 , FIG. 3 is a schematic diagram of a system architecture of application switching according to an embodiment of the present application.

In order to improve the efficiency of application switching, the embodiments of the present application provide an application switching method and apparatus, and the application switching method and apparatus provided by the embodiments of the present application are further described below in detail.

Referring to FIG. 4 , FIG. 4 provides a schematic flowchart of an application switching method according to an embodiment of the present application. The application switching method includes the following operations 410 to 430 . The method execution body shown in FIG. 4 may be a terminal device, or the body may be a chip in the terminal device, and the terminal device may include user keys and a display unit. When the terminal device executes the process shown in Figure 4, it may include the following steps:

410. Detect a user operation on the terminal device through the driver layer of the terminal device system.

Specifically, since the driver layer can directly interact with the user key, the driver layer can detect the user key, and if a user operation is detected, a corresponding program can be triggered. The user operation may include operations such as clicking, touching, and long pressing on the user key. The embodiments of the present application do not limit the specific actions of the user operation, and may be set and modified according to actual conditions.

Before the user operation on the terminal device is detected by the driver layer of the terminal device system, the framework layer in the terminal device system can obtain the associated information of each application program in the preset application program set. Wherein, the preset application set may be a running application set; or, the preset application set may also be a user setting application set, and the user setting application set may include running applications , and can also include applications that are not running.

FIG. 5 is a schematic diagram of a preset application set, and the set may include application 1 to application 6. Of course, this embodiment of the present application does not limit the number of applications included in the set. The application 1 to application 6 may all be running applications (that is, the set is the set of running applications), or only some of the applications are in the running state (that is, the set is the set of applications set by the user) . The framework layer may add the associated information of each application in the preset application set to the monitoring stack.

420. If a first user operation event for the user key is detected through the driver layer, switch from the currently displayed user interface of the first application to displaying the user interface of the second application.

Wherein, the display unit of the terminal device currently displays the user interface of the first application program, and the user interface of the first application program is the display interface of components such as icons and function layouts associated with the first application program.

In a possible implementation manner, in the case where the preset application program set is the application program set set by the user, if the terminal device detects through the driver layer that the number of times the user key is pressed is the first number of times, it can be determined that The first user operation event is triggered. The first user operation event is that the number of times the user presses the user key is the first number of times. In this way, the driver layer can send the first switching message to the framework layer. Wherein, the first switching message may instruct to switch to the user interface of the application program that is displayed next to the user interface of the currently displayed first application program. After receiving the first switching message, the framework layer can determine, according to the first switching message, the previous application to switch to the first application, and the application is the second application. The framework layer can read the associated information corresponding to the second application from the monitoring stack. In this way, the framework layer can switch from the currently displayed user interface of the first application program to the user interface displaying the second application program.

For example, as shown in FIG. 5 , assuming that the application 3 is the first application, the display unit of the current terminal device displays the user interface of the application 3 . When the driver layer of the terminal device system detects the first user operation event, if the number of times the user presses the user key is 1, a first switching message can be generated, and the first switching message is used to instruct to switch to the display application 2 user interface. Wherein, the application 2 may be in a non-running state, or may be in an already running state. If the application 2 is in the running state, it is also in the background running state. When the application 2 is in the non-running state and the first user operation event is triggered, the framework layer can determine to switch the application 2 from the non-running state to the running state, and switch from displaying the user interface of the application 3 to displaying the application 2 user interface. As shown in Figure 6, after the terminal device detects the first user operation event, it can directly switch from the user interface displaying the first application to the user interface displaying the second application.

In a possible implementation manner, when the preset application set is the running application set, if the terminal device determines that the first user operation event is triggered, the driver layer may send the first switching message to the framework layer. Wherein, the first switching message may instruct to switch to display the user interface of the already-running application program that is ranked above the user interface of the currently displayed first application program. After receiving the first switching message, the framework layer can determine, according to the first switching message, the last running application to be switched to the first application, and the running application is the second application. For example, application 1, application 3, and application 5 in FIG. 5 are in the running state, other applications are in the non-running state, and application 3 is the first application, then the previous one of the first application has been running The application is application 1.

430. If the second user operation event for the user key is detected through the driver layer, switch from the user interface displaying the first application to the user interface displaying the third application, and the second application is different from the third application. s application.

In a possible implementation manner, in the case that the preset application set is the set of applications set by the user, if the terminal device detects through the driver layer that the number of times the user's key is pressed is the second number of times, it can be determined that the trigger is triggered the second user action event. The second user operation event is that the number of times the user presses the user key is the second number of times. In this way, the driver layer can send the second switching message to the framework layer. Wherein, the second switching message may indicate switching to display the user interface of the application program next to the user interface of the currently displayed first application program. After receiving the second switching message, the framework layer can determine, according to the second switching message, the next application to switch to the first application, that is, the third application, and can read the third application in the monitoring stack Corresponding association information. In this way, the framework layer can switch from the currently displayed user interface of the first application program to the user interface displaying the third application program.

For example, as shown in FIG. 5 , assuming that the application 3 is the first application, the display unit of the current terminal device displays the user interface of the application 3 . When the driver layer of the terminal device system detects the second user operation event, if the number of times the user presses the user key is 2, a second switching message can be generated, and the second switching message is used to instruct switching to the display application 4 user interface. Wherein, the application 4 may be in a non-running state, or may be in an already running state. If the application 4 is in the running state, it is also in the background running state. When the application 4 is in the non-running state and the second user operation event is triggered, the framework layer can determine to switch the application 4 from the non-running state to the running state, and switch from displaying the user interface of the application 3 to displaying the application 4 user interface. As shown in FIG. 6 , when the terminal device detects the second user operation event, it can directly switch from the user interface displaying the first application to the user interface displaying the third application.

In a possible implementation manner, when the preset application set is the running application set, if the terminal device determines that the second user operation event is triggered, the driver layer may send a second switching message to the framework layer. Wherein, the second switching message may instruct to switch to display the user interface of the already-running application that is next to the user interface of the currently displayed first application. After receiving the second switching message, the framework layer can determine the next running application to switch to the first application according to the second switching message, and the running application is the third application. For example, application 1, application 3, and application 5 in FIG. 5 are in the running state, other applications are in the non-running state, and application 3 is the first application, then the next one of the first application is running The application is application 5.

It should be noted that, if the first application program is the application program 1 in Fig. 5, the previous application program of the application program 1 is the application program 6, that is, the application program with the largest index value in the preset application program set. If the first application program is the application program 6 in FIG. 5 , the next application program of the application program 6 is the application program 1 , that is, the application program with the smallest index value in the preset application program set.

In a possible implementation manner, if the preset set of applications is a set of running applications, the arrangement order of each application in the set may also be arranged according to the order in which each application is opened.
