Abstract

The invention provides a multi-video-window hierarchy switching method and device. The method comprises the followings steps: detecting a target video window needing hierarchy switching; displaying a current video picture of the target video window on a main thread canvas; removing the target video window from a current layout; setting a hierarchy of the target video window removed from the current layout as an uppermost layer; and adding the target video widow which is set as the uppermost layer into an original layout, and clearing the video picture displayed on the main thread canvas. Through application of the embodiment of the invention, video window switching can be realized, and a blank screen effect occurring in a video window switching process is avoided at the same time.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a multi-video window level switching method and device. Background technique [0002] In the Android (Android) system, the video is generally rendered through SurfaceView (surface view) or its subclass GLSurfaceView (Graphics Library SurfaceView, graphics library surface view), because SurfaceView supports selection under multi-threading, which can achieve ordinary View ( view) cannot reach the rendering frame rate, so as to meet the needs of video playback. [0003] At present, when playing multiple videos at the same time in one screen and interlacing occurs, when it is necessary to dynamically switch the hierarchical relationship of videos, according to the characteristics of SurfaceView, switching will not be possible. The reason is that the surface in SurfaceView has a hierarchical relationship in the Z direction, which is determined when SurfaceView ...
