Android 模擬輸入那點事

因工作原因，需要用到模擬輸入這個東東，查閱了一些資料，實現方式有多種，我大概分為兩類，命令行類和程序類。

命令行類包括自動化測試組件monkeyrunner，getevent/setevent命令，input命令

程序類包括MotionEvent，AccessibilityService，反射等

本人對這塊也是剛剛接觸，幾種方式不評優劣，僅就工作中用到的知識點做記錄，以備后用。

1、命令行開啟和關閉應用

adb shell am start -n 包名/入口activity   //開啟某個應用
adb shell am force-stop 包名               //關閉某個應用

2、input命令參數

Usage: input [<source>] <command> [<arg>...]The sources are:trackball                    //滾動球joystick                     //操縱桿touchnavigation              //觸摸導航 mouse                        //鼠標keyboard                     //鍵盤gamepad                      //手柄touchpad                     //觸摸板dpad                         //模擬手柄stylus                       //尖筆touchscreen                  //觸摸屏

The commands and default sources are:text <string> (Default: touchscreen)  //輸入文字keyevent [--longpress] <key code number or name> ... (Default: keyboard) //鍵盤操作tap <x> <y> (Default: touchscreen)   //點擊swipe <x1> <y1> <x2> <y2> [duration(ms)] (Default: touchscreen)  //滑動操作press (Default: trackball)roll <dx> <dy> (Default: trackball)

其中我們常用的就是keyboard和touchscreen，用起來也很簡單。

3、keyevent值對應表

0 -->  "KEYCODE_UNKNOWN"
1 -->  "KEYCODE_MENU"
2 -->  "KEYCODE_SOFT_RIGHT"
3 -->  "KEYCODE_HOME"

84 -->  "KEYCODE_SEARCH" 85 -->  "TAG_LAST_KEYCODE"

4、getevent/sendevent

首先執行getevent -p命令獲取android設備上所有的input設備，找到screen設備

執行getevent 設備編號，在屏幕上做操作，記錄getevent的結果。

type，code，value0003 0036 000002a4

需要注意的是getevent獲取的值是16進制的，sendevent發送的是10進制，需要做一下轉換
