  第一种方法：

adb shell dumpsys window displays

android@tesdt-Precision-T1700:~/Desktop$ adb shell dumpsys window displays
Dump time : 2016年10月8日 下午10:29:22
WINDOW MANAGER DISPLAY CONTENTS (dumpsys window displays)
  Display: mDisplayId=0

    deferred=false layoutNeeded=false

第二种方法：

adb shell dumpsys window | grep init

android@tesdt-Precision-T1700:~/Desktop$ adb shell dumpsys window | grep init
    init=720x1280 320dpi cur=720x1280 app=720x1184 rng=720x672-1196x1136

其实这二种方法都是依赖对手机所有的window信息的查看：

adb shell dumpsys window

我们可以查看当前手机所有的windows详细信息：

adb shell dumpsys window windows

• 查看当前所有的activity

adb shell dumpsys activity activities > activities.txt

adb shell dumpsys activity

• 查看当前是那个activity

adb shell dumpsys activity | grep -i foc

android@tesdt-Precision-T1700:~/Desktop$ adb shell dumpsys activity | grep -i foc
