Setting view alpha in runtime is slow, how to speed it up?
可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 由 翻译 强力驱动 问题: I have two ImageViews which I hope imageViewA is overlapped by imageViewB, and when user select a seekbar, the alpha value of imageViewB will change accordingly (e.g., becoming translucent and users can see part of imageViewA). It supposes to be a easy coding task, however I found the performance is VERY slow in my Galaxy S6. I have tried all setAlpha(int), setAlpha(float), and setImageAlpha(float), but get no hope. It seems the most related question post is App UI operations (setting alpha, setting margins, etc.) very slow on 4.4
