Usage of adb shell input

The input command was used in the gamma automated test of the LCD module recently, so we also learned about the use of the command. When you run the ADB shell and then enter input, the operation will output input using the following method:

Usage:input [<source>] <command> [<arg> ...]

The sources are:
Trackball
Joystick
Touchnavigation
Mouse
Keyboard
GamePad
Touchpad
Dpad
Stylus
Touchscreen


The commands and default sources are:
Text <string> (Default:touchscreen)
KeyEvent [--longpress] <key code number or name> ... (Default:keyboard)
Tap <x> <y> (Default:touchscreen)
Swipe <x1> <y1> <x2> <y2> [Duration (ms)] (Default:touchscreen)
Press (Default:trackball)

Roll <dx> <dy> (Default:trackball)

This is very simple, it does not explain!

First, KeyEvent events

I used to have two.

Swipe left screen adb shell input keyevent 21

Swipe right on the screen adb shell input keyevent 22

Other keyevent events and the corresponding num are as follows:

0--"keycode_unknown"
1--"Keycode_menu"
2--"Keycode_soft_right"
3--"Keycode_home"
4--"Keycode_back"
5--"Keycode_call"
6--"Keycode_endcall"
7--"Keycode_0"
8--"Keycode_1"
9--"keycode_2"
Ten--"Keycode_3"
