推荐答案

我不知道有关计算FPS（我想这应该做全系统和按次不计），但你可以使用的层次浏览器的个人主页每个查看性能。它给你测量，计算布局，并以毫秒为单位绘制每个查看所需的时间，并帮助您找到缓慢查看对象通过展示说明糟糕的表现黄色和红色圆圈。

I don't know about calculating FPS (I guess that should be done system-wide and is not calculated per view), but you can use Hierarchy Viewer to profile performance of each View. It gives you time needed to measure, calculate layout of, and draw each View in milliseconds, and helps you to find slow View objects by showing yellow and red circles indicating bad performance.
