See forum post Any way to view Android screen remotely without root?
(查看论坛帖子是否可以无root权限远程查看Android屏幕？)
- Post #9 . (-发布＃9 。)
- Connect the device via USB and make sure debugging is working;
(通过USB连接设备并确保调试正常；)
-
adb tcpip 5555 . (adb tcpip 5555 。)
This makes the device to start listening for connections on port 5555; (这使设备开始侦听端口5555上的连接。)
- Look up the device IP address with
adb shell netcfg or adb shell ifconfig with 6.0 and higher; (使用6.0或更高版本的adb shell netcfg或adb shell ifconfig查找设备IP地址；)
- You can disconnect the USB now;
(您可以立即断开USB连接。)
-
adb connect <DEVICE_IP_ADDRESS>:5555 . (adb connect <DEVICE_IP_ADDRESS>:5555 。)
This connects to the server we set up on the device on step 2; (这将连接到我们在步骤2上在设备上设置的服务器。)
- Now you have a device over the network with which you can debug as usual.
(现在，您可以通过网络使用设备进行调试了。)
To switch the server back to the USB mode, run adb usb , which will put the server on your phone back to the USB mode.
(要将服务器切换回USB模式，请运行adb usb ，这会将手机上的服务器恢复为USB模式。)
If you have more than one device, you can specify the device with the -s option: adb -s <DEVICE_IP_ADDRESS>:5555 usb . (如果有多个设备，则可以使用-s选项指定设备： adb -s <DEVICE_IP_ADDRESS>:5555 usb 。)
No root required!
(无需root！)
To find the IP address of the device: run adb shell and then netcfg .
(要查找设备的IP地址：运行adb shell ，然后运行netcfg 。)
You'll see it there. (您会在那看到它。)
To find the IP address while using OSX run the command adb shell ip route . (要在使用OSX时查找IP地址，请运行命令adb shell ip route 。)
WARNING : leaving the option enabled is dangerous, anyone in your network can connect to your device in debug, even if you are in data network.
(警告 ：启用该选项很危险，即使您处于数据网络中，网络中的任何人都可以通过调试连接到设备。)
Do it only when connected to a trusted Wi-Fi and remember to disconnect it when done! (仅在连接到受信任的Wi-Fi时执行此操作，并记住在完成连接后将其断开连接！)
@Sergei suggested that line 2 should be modified, commenting: "-d option needed to connect to the USB device when the other connection persists (for example, emulator connected or other Wi-Fi device)".
(@Sergei建议修改第2行，注释：“-d选项需要在其他连接持续存在时连接到USB设备（例如，仿真器连接或其他Wi-Fi设备）”。)
This information may prove valuable to future readers, but I rolled-back to the original version that had received 178 upvotes.
(该信息可能对将来的读者有价值，但是我回滚到最初的版本，该版本已经获得178次投票。)
On some device you can do the same thing even if you do not have an USB cable :
(在某些设备上 ，即使没有USB电缆，您也可以做同样的事情：)
- Enable ADB over network in developer setting
(在开发人员设置中通过网络启用ADB) 
It should show the IP address
(它应该显示IP地址)
-
adb connect <DEVICE_IP_ADDRESS>:5555
- Disable the setting when done
(完成后禁用设置)
Using Android Studio there is a plugin allowing you to connect USB Debugging without the need of using any ADB command from a terminal.
(使用Android Studio，有一个插件可让您连接USB调试，而无需使用任何来自终端的ADB命令。)
