Android(安卓)如何快速定位当前页面是哪个Activity or Fragment

在日常需求开发中，经常碰到不太熟悉的模块，如何快速定位相应页面对应的Activity/Fragment ？

(1)查看当前Activity ：adb shell "dumpsys window w | grep name="

(2)查看当前栈顶的Activity ：adb shell dumpsys activity | grep "mFocusedActivity"

(3)查看当前栈顶的Activity的Fragment ：adb shell dumpsys activity your.package.name

也可以不用包名，而直接使用"top"选项：adb shell dumpsys activity top
