An electronic device, wherein the electronic device comprises a display, a memory, and at least one processor;

• the memory is coupled to the at least one processor;
• the memory is configured to store computer program code comprising computer instructions, which when executed by the at least one processor, cause the electronic device to:
• display a first interface of a first application in a first display area of the display, and display a second interface of a second application in a second display area of the display;
• receive a first operation entered by a user, and display a home screen of the electronic device on the display in full screen in response to the first operation;
• display a third interface of a third application in the first display area, and display a fourth interface of a fourth application in the second display area in response to a second operation entered by the user;
• switch a split screen locking control from a first display state to a second display state to enable a split screen locking function of the electronic device, in response to an operation by the user;
• receive a third operation entered by the user in the first display area, wherein the third operation is to lock display content in the first display area;
• and
• invoke an activity task stack corresponding to the first display area based on the third operation, to set a lock status of the activity task stack;
• switch a display status of a lock control of the first display area to a locking state based on the lock status of the activity task stack;
• receive a fourth operation entered by the user;
• and
• in response to the fourth operation, display the third interface in the first display area, and display the home screen in the second display area, wherein an operation manner of the fourth operation is the same as an operation manner of the first operation.

A non-transitory computer-readable storage medium, comprising instructions, wherein when the instructions are run on an electronic device, the electronic device is caused to:

• display a first interface of a first application in a first display area of the display, and display a second interface of a second application in a second display area of the display;
• receive a first operation entered by a user, and display a home screen of the electronic device on the display in full screen in response to the first operation;
• display a third interface of a third application in the first display area, and display a fourth interface of a fourth application in the second display area in response to a second operation entered by the user;
• switch a split screen locking control from a first display state to a second display state to enable a split screen locking function of the electronic device, in response to an operation by the user;
• receive a third operation entered by the user in the first display area, wherein the third operation is to lock display content in the first display area;
• and
• invoke an activity task stack corresponding to the first display area based on the third operation, to set a lock status of the activity task stack;
• switch a display status of a lock control of the first display area to a locking state based on the lock status of the activity task stack;
• receive a fourth operation entered by the user;
• and
• in response to the fourth operation, display the third interface in the first display area, and display the home screen in the second display area, wherein an operation manner of the fourth operation is the same as an operation manner of the first operation.
