Abstract: A screen window redrawing method includes detecting whether a current device is in a screen-off state. If it is detected that the current device is in the screen-off state, whether a screen form of the current device changes is detected by using obtained screen form information before screen-off and obtained screen form information after screen-off. If it is detected that the screen form changes, a to-be-displayed screen is determined based on the screen form information after screen-off. A window of the to-be-displayed screen is redrawn based on an obtained size of a display area of the to-be-displayed screen.
