Android 模拟输入那点事

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。

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。

type，code，value

  000002a4

需要注意的是getevent获取的值是16进制的，sendevent发送的是10进制，需要做一下转换
