Android Studio查看布局层级的方法

1、使用Android Studio自带的Layout Inspector；

2、使用SDK工具包中的UI Automator Viewer；

3、使用dumpsys命令

通过adb shell dumpsys activity top命令，拿到activity的快照，内部包含布局信息。

也可以通过指定包名，只获取你自己应用的Activity信息：

adb shell dumpsys activity com.ldd.layoutapp（包名）

E:\Android\AndroidStudioProjects\LayoutApp>adb shell dumpsys activity com.ldd.layoutapp
