The invention relates to an implementation method of a barrage effect, comprising the following steps: step 1, custom barrage metadata class DanmakuBean is used for storing barrage metadata; step 2, custom barrage layout class DanmakuItem is used for displaying barrage; step 3, custom barrage data class DrawerBean is used for providing relevant computation of barrage movement; step 4, custom classDanmakuItemDrawer is used for drawing barrage items; and step 5, custom class DanmakuView is used for drawing and rendering in the thread. According to the method, the custom class is used for drawing the barrage items, and local rendering and drawing updating are carried out on barrage information by sub threads in the custom class, so that the influence to the whole interface is little, the fluency is improved, lag is reduced, the user experience is enhanced, and the memory and cpu occupation is also reduced.
