连上ADB线后：

截图

创建一个BAT文件，用于截图，直接双击运行即可将图片保存到D:\screenshot目录，提前创建好screenshot文件夹哦

@echo off
echo on
adb root
adb remount
adb shell /system/bin/screencap -p /sdcard/screenshot.png
set t=%DATE:~0,4%%DATE:~5,2%%DATE:~8,2%_%TIME:~0,2%%TIME:~3,2%%TIME:~6,2%
set "t=%t: =%"
adb pull /sdcard/screenshot.png D:\screenshot\%t%.png
adb shell rm /sdcard/*.png
pause 

录屏MP4

adb root
adb remount
adb shell screenrecord --size 1280x720 /sdcard/demo.mp4
adb pull /sdcard/demo.mp4 D:\screenshot

非常好用。
