Android 模拟输入那点事

行是知之始,知是行之成。这篇文章主要讲述Android 模拟输入那点事相关的知识，希望能为你提供帮助。
因工作原因，需要用到模拟输入这个东东，查阅了一些资料，实现方式有多种，我大概分为两类，命令行类和程序类。
命令行类包括自动化测试组件monkeyrunner，getevent/setevent命令，input命令
程序类包括MotionEvent，AccessibilityService，反射等
本人对这块也是刚刚接触，几种方式不评优劣，仅就工作中用到的知识点做记录，以备后用。
1、命令行开启和关闭应用

adb shell am start -n 包名/入口activity//开启某个应用 adb shell am force-stop 包名//关闭某个应用

2、input命令参数

Usage: input [< source> ] < command> [< arg> ...]The sources are: trackball//滚动球 joystick//操纵杆 touchnavigation//触摸导航 mouse//鼠标 keyboard//键盘 gamepad//手柄 touchpad//触摸板 dpad//模拟手柄 stylus//尖笔 touchscreen//触摸屏The commands and default sources are: text < string> (Default: touchscreen)//输入文字 keyevent [--longpress] < key code number or name> ... (Default: keyboard) //键盘操作 tap < x> < y> (Default: touchscreen)//点击 swipe < x1> < y1> < x2> < y2> [duration(ms)] (Default: touchscreen)//滑动操作 press (Default: trackball) roll < dx> < dy> (Default: trackball)

其中我们常用的就是keyboard和touchscreen，用起来也很简单。
3、keyevent值对应表

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" 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 --> "TAG_LAST_KEYCODE"

4、getevent/sendevent
首先执行getevent -p命令获取android设备上所有的input设备，找到screen设备
执行getevent 设备编号，在屏幕上做操作，记录getevent的结果。
