METHOD FOR DISPLAYING INTERFACE OF APPLICATION PROGRAM AND ELECTRONIC DEVICE

An application interface display method and an electronic device are provided. When the electronic device detects a first user operation of scaling an application interface, a system display pixel density is generated corresponding to the first user operation, where the system display pixel density is not a system display pixel density that is actually set by a current system. A change of a system configuration triggers an update of application setting. After the system display pixel density dispatched by the first user operation is obtained, a first application loads a corresponding application resource and displays an upscale or downscale application interface. Through implementation of this method, a user interface of an application can implement quick scaling display. This meets a requirement of a user for upscaling or downscaling displayed content in the application interface, provides a user with a friendly operating environment, improves visual experience of the user, facilitates a developer, and reduces development resources of an application.
