Abstract: A method includes receiving an instruction for switching display orientation of a screen from a first display orientation to a second display orientation, and obtaining display orientation configuration information of page display of an application currently displayed on the screen. The method also includes modifying the display orientation configuration information and a page display size of the application, when the display orientation configuration information sets that the application supports only display in the first display orientation. The method also includes switching the display orientation of the screen according to the instruction, and displaying the application with the modified page display size on the screen after the display orientation of the application is switched from the first display orientation to the second display orientation.

Abstract: A DPI adaptation method and an electronic device are provided. The DPI adaptation method includes: obtaining dots per inch DPI of the electronic device and DPI supported by an application, where the DPI of the electronic device includes at least one of logical DPI of the electronic device or physical DPI of the electronic device; determining a general display type of the electronic device, where the general display type is a most-used display type of the electronic device; determining target DPI according to the DPI of the electronic device, the DPI supported by the application, and the general display type; and displaying a user interface of the application by using the target DPI.
