前言

通过adb shell input可以模拟android各种输入事件，比如文字、按键、触摸等等。

adb shell inputUsage: input [<source>] <command> [<arg>...]The sources are:  keyboard  mouse  joystick  touchnavigation  touchpad  trackball  dpad  stylus  gamepad  touchscreenThe 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)

基本用法

usage: input [text|keyevent] input text <string> input keyevent <event_code>

输入文字

列子：

adb shell input text sample-text

而包含字符可以使用引号包裹，其中%s代表空格。

adb shell input text "insert%syour%stext%shere"

模拟按键

通过adb shell input keyevent可以模拟按键，后面跟按键code。比如：

adb shell input keyevent 82

所有按键code列表如下：

0 --> "KEYCODE_0" 1 --> "KEYCODE_SOFT_LEFT" 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" 10 --> "KEYCODE_3" 11 --> "KEYCODE_4" 12 --> "KEYCODE_5" 13 --> "KEYCODE_6" 14 --> "KEYCODE_7" 15 --> "KEYCODE_8" 16 --> "KEYCODE_9" 17 --> "KEYCODE_STAR" 18 --> "KEYCODE_POUND" 19 --> "KEYCODE_DPAD_UP" 20 --> "KEYCODE_DPAD_DOWN" 21 --> "KEYCODE_DPAD_LEFT" 22 --> "KEYCODE_DPAD_RIGHT" 23 --> "KEYCODE_DPAD_CENTER" 24 --> "KEYCODE_VOLUME_UP" 25 --> "KEYCODE_VOLUME_DOWN" 26 --> "KEYCODE_POWER" 27 --> "KEYCODE_CAMERA" 28 --> "KEYCODE_CLEAR" 29 --> "KEYCODE_A" 30 --> "KEYCODE_B" 31 --> "KEYCODE_C" 32 --> "KEYCODE_D" 33 --> "KEYCODE_E" 34 --> "KEYCODE_F" 35 --> "KEYCODE_G" 36 --> "KEYCODE_H" 37 --> "KEYCODE_I" 38 --> "KEYCODE_J" 39 --> "KEYCODE_K" 40 --> "KEYCODE_L" 41 --> "KEYCODE_M" 42 --> "KEYCODE_N" 43 --> "KEYCODE_O" 44 --> "KEYCODE_P" 45 --> "KEYCODE_Q" 46 --> "KEYCODE_R" 47 --> "KEYCODE_S" 48 --> "KEYCODE_T" 49 --> "KEYCODE_U" 50 --> "KEYCODE_V" 51 --> "KEYCODE_W" 52 --> "KEYCODE_X" 53 --> "KEYCODE_Y" 54 --> "KEYCODE_Z" 55 --> "KEYCODE_COMMA" 56 --> "KEYCODE_PERIOD" 57 --> "KEYCODE_ALT_LEFT" 58 --> "KEYCODE_ALT_RIGHT" 59 --> "KEYCODE_SHIFT_LEFT" 60 --> "KEYCODE_SHIFT_RIGHT" 61 --> "KEYCODE_TAB" 62 --> "KEYCODE_SPACE" 63 --> "KEYCODE_SYM" 64 --> "KEYCODE_EXPLORER" 65 --> "KEYCODE_ENVELOPE" 66 --> "KEYCODE_ENTER" 67 --> "KEYCODE_DEL" 68 --> "KEYCODE_GRAVE" 69 --> "KEYCODE_MINUS" 70 --> "KEYCODE_EQUALS" 71 --> "KEYCODE_LEFT_BRACKET" 72 --> "KEYCODE_RIGHT_BRACKET" 73 --> "KEYCODE_BACKSLASH" 74 --> "KEYCODE_SEMICOLON" 75 --> "KEYCODE_APOSTROPHE" 76 --> "KEYCODE_SLASH" 77 --> "KEYCODE_AT" 78 --> "KEYCODE_NUM" 79 --> "KEYCODE_HEADSETHOOK" 80 --> "KEYCODE_FOCUS" 81 --> "KEYCODE_PLUS" 82 --> "KEYCODE_MENU" 83 --> "KEYCODE_NOTIFICATION" 84 --> "KEYCODE_SEARCH" 85 --> "KEYCODE_MEDIA_PLAY_PAUSE"86 --> "KEYCODE_MEDIA_STOP"87 --> "KEYCODE_MEDIA_NEXT"88 --> "KEYCODE_MEDIA_PREVIOUS"89 --> "KEYCODE_MEDIA_REWIND"90 --> "KEYCODE_MEDIA_FAST_FORWARD"91 --> "KEYCODE_MUTE"92 --> "KEYCODE_PAGE_UP"93 --> "KEYCODE_PAGE_DOWN"94 --> "KEYCODE_PICTSYMBOLS"...122 --> "KEYCODE_MOVE_HOME"123 --> "KEYCODE_MOVE_END"

最新的可以参考官方文档：https://developer.android.com/reference/android/view/KeyEvent.html

模拟触摸

通过 tap可以模拟触摸事件，参数是<x, y>

adb shell input tap 500 1450

滑动则可以通过swipe模拟，参数是<x1 y1 x2 y2 time>

adb shell input swipe 100 500 100 1450 100

巧妙使用swipe也可以模拟长按事件：

adb shell input swipe 100 500 100 500 250
