问题描述

我知道这已经被问了很多次这里的计算器,但我着迷的Facebook Messenger的如何绘制Chatheads。

I know this has already been asked a lot of times here on StackOverflow, but I'm fascinated how Facebook Messenger draws the Chatheads.

我跟着这个以放置的ImageView为覆盖。然而,拖拽它的非常不畅,不像Chatheads这表现出无比流畅的动画效果。

I followed this tutorial to place an ImageView as an overlay. However, dragging it around is very sluggish, unlike Chatheads which show extremely smooth animation.

打开显示GPU视图更新,在开发人员选项选项闪烁的屏幕,同时被拖动一个Chathead。然而,拖着ImageView的不会触发任何闪烁。

Turning on the "Show GPU view updates" option in Developer options flashes the screen while a Chathead is being dragged. However, dragging my ImageView doesn't trigger any flashing.

下面是一个小的截屏:
