Abstract: Embodiments of this application provide an animation effect display method and an electronic device, and relate to the field of electronic technologies. According to the animation effect display method provided in an embodiment of this application, before an animation effect is displayed, a UI thread of an application, or a rendering thread of the application, or a rendering process determines controls whose properties change in duration of the animation effect, and determines properties of controls on an interface of each frame, and then the rendering thread of the application or the rendering process generates, based on the properties of the controls on the interface of each frame, a bitmap corresponding to the interface of the frame. Because the properties like sizes and locations of the controls on the interface of each frame are determined before the animation effect is displayed, the UI thread does not need to perform measurement, layout, and drawing and recording (recording) on the interface of each frame, so that display of the animation effect is not affected by UI thread blocking.

Abstract: A vertical synchronization signal-based control method. The method includes the electronic device draws a first layer of a first application in response to a first vertical synchronization signal, and buffers the first layer to a first buffer queue. The electronic device performs, in response to a second vertical synchronization signal, layer composition on the layer buffered in the first buffer queue, to obtain an image frame. The electronic device adjusts a signal period of the first vertical synchronization signal to first duration if a quantity of layers buffered in the first buffer queue is less than a first preset threshold, where the first duration is less than a signal period of the second vertical synchronization signal.
