Android 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

CHUANCUI-MC0:~ chuancui$ adb shell dumpsys --h
usage: dumpsys
         To dump all services.
or:
       dumpsys [-t TIMEOUT] [--help | -l | --skip SERVICES | SERVICE [ARGS]]
         --help: shows this help
         -l: only list services, do not dump them
         -t TIMEOUT: TIMEOUT to use in seconds instead of default 10 seconds
         --skip SERVICES: dumps all services but SERVICES (comma-separated list)
         SERVICE [ARGS]: dumps only service SERVICE, optionally passing ARGS to it
