bixiaopeng@bixiaopeng ~$ adb shell screencap -v
screencap: invalid option -- v
usage: screencap [-hp] [-d display-id] [FILENAME]
-h: this message
-p: save the file as a png.
-d: specify the display id to capture, default 0.
If FILENAME ends with .png it will be saved as a png.
If FILENAME is not given, the results will be printed to stdout.
注意:
如果文件名以.png结尾时,它将保存为png文件
如果文件名没有给出,则结果被会被输出到stdout
$ adb shell screencap -p /sdcard/screen.png
$ adb pull /sdcard/screen.png
$ adb shell rm /sdcard/screen.png
这种方法比较麻烦,需要3步:1. 截图保存到sdcard 2.将图片导出 3.删除sdcard中的图片
$ adb shell screencap -p | sed 's/\r$//' > screen.png
执行adb shell 将\n转换\r\n, 因此需要用sed删除多余的\r
$ alias and-screencap="adb shell screencap -p | sed 's/\r$//'"
$ and-screencap > screen.png
以后就可以方便的用and-screencap > 直接将截图保存到电脑上了
adb shell screenrecord /sdcard/demo.mp4
说明:录制手机屏幕,视频格式为mp4,存放到手机sd卡里,默认录制时间为180s
参数: --time-limit
adb shell screenrecord --time-limit 10 /sdcard/demo.mp4
说明:限制视频录制时间为10s,如果不限制,默认180s
参数: --size
adb shell screenrecord --size 1280*720 /sdcard/demo.mp4
说明:录制视频,分辨率为1280*720,如果不指定默认使用手机的分辨率,为获得最佳效果,请使用设备上的高级视频编码(AVC)支持的大小
参数: --bit-rate
adb shell screenrecord --bit-rate 6000000 /sdcard/demo.mp4
说明:指定视频的比特率为6Mbps,如果不指定,默认为4Mbps. 你可以增加比特率以提高视频质量或为了让文件更小而降低比特率
参数: --verbose
