在日常需求開發中，經常碰到不太熟悉的模塊，如何快速定位相應頁面對應的Activity/Fragment ？

?

(1)查看當前Activity ?：adb shell "dumpsys window w | grep name="

(2)查看當前棧頂的Activity ：adb shell dumpsys activity | grep "mFocusedActivity"

(3)查看當前棧頂的Activity的Fragment ：adb shell dumpsys activity your.package.name

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