一、有线链接和无线链接

1.有线链接

adb链接成功（插上手机线后，开发者也打开后，usb调试也打开）后，然后在终端输入

scrcpy

2.无线链接

其实就是adb无线链接后输入scrcpy：

adb无线链接

1. 将手机和电脑连在同一个局域网WIFI下
2. 查看手机的IP address (in Settings → About phone → Status).
3. 链接手机和电脑的数据线

adb tcpip 5555

4. 现在可以拔掉插头了
5. 比如你的手机IP是192.168.1.101

adb connect 192.168.1.101:5555

运行scrcpy

6. 现在运行scrcpy就可以显示手机模拟器了

scrcpy

二、快捷键

Action	Shortcut	Shortcut (macOS)
Switch fullscreen mode	Ctrl+f	Cmd+f
Resize window to 1:1 (pixel-perfect)	Ctrl+g	Cmd+g
Resize window to remove black borders	Ctrl+x | Double-click¹	Cmd+x | Double-click¹
Click on HOME	Ctrl+h | Middle-click	Ctrl+h | Middle-click
Click on BACK	Ctrl+b | Right-click²	Cmd+b | Right-click²
Click on APP_SWITCH	Ctrl+s	Cmd+s
Click on MENU	Ctrl+m	Ctrl+m
Click on VOLUME_UP	Ctrl+↑ (up)	Cmd+↑ (up)
Click on VOLUME_DOWN	Ctrl+↓ (down)	Cmd+↓ (down)
Click on POWER	Ctrl+p	Cmd+p
Power on	Right-click²	Right-click²
Turn device screen off (keep mirroring)	Ctrl+o	Cmd+o
Expand notification panel	Ctrl+n	Cmd+n
Collapse notification panel	Ctrl+Shift+n	Cmd+Shift+n
Copy computer clipboard to device	Ctrl+Shift+v	Cmd+Shift+v
Enable/disable FPS counter (on stdout)	Ctrl+i	Cmd+i

¹Double-click on black borders to remove them.
²Right-click turns the screen on if it was off, presses BACK otherwise.

三、其他命令

1.更改模拟器窗口的名字

scrcpy --window-title 'My device'

2.只读模式Read-only

To disable controls (everything which can interact with the device: input keys,
mouse events, drag&drop files):

scrcpy --no-control

scrcpy -n  # short version

3.录屏

mp4格式或mkv格式

scrcpy --record file.mp4

scrcpy -r file.mp4  # short version

要终止的话，Ctrl+C，保存在当前路径下

4.显示一部分屏幕Crop

The device screen may be cropped to mirror only part of the screen.

This is useful for example to mirror only one eye of the Oculus Go:

scrcpy --crop 1224:1440:0:0   # 1224x1440 at offset (0,0)

scrcpy -c 1224:1440:0:0       # short version

5.改变传输速率Change bit-rate

The default bit-rate is 8 Mbps. To change the video bitrate (e.g. to 2 Mbps):

scrcpy --bit-rate 2M

scrcpy -b 2M  # short version

6.改变分辨率

这样可以降低延迟（每帧传输的东西少了，帧数就上去了）

scrcpy --max-size 1024
scrcpy -m 1024  # short version

意思修改高和宽中最大的大小（对于手机来说是高），比如1920×1080就变成1024×576.
