在http://blog.csdn.net/ericahdu 的帮助下，实现了模拟按键，在此，首先表示感谢：）在源码下写程序可以摆脱SDK的限制，毕竟SDK开放的API有限，比如我们实现模拟按键时，需要用到IWindowManager这个类，但是SDK中是不提供这个类的首先下载编译源码，然后在源码的frameworks/base/cmds下新建一个文件夹作为你新扩展模块的一个目录。比如叫做autotest，在autotest下创建一个java文件，比如AutoTest.java。编写你的程序代码，在此你可以使用IWindowManager类，在此，我模拟了按键key,长按键keypress，点触笔touch，点触笔长按touchpress，以及移动move等，代码如下：import android.view.MotionEvent;import android.view.KeyEvent;import android.view.IWindowManager;import android.os.ServiceManager;import android.os.SystemClock;import android.os.RemoteException;import android.util.Log;public class AutoTest {public static void main(String args[])throws Exception{String[] mArgs = args;try{String opt = mArgs[0];if(opt.equals("touch")){float x = Float.valueOf(mArgs[1]);float y = Float.valueOf(mArgs[2]);MotionEvent e = MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_DOWN, x, y, 0);sendPointerSync(e);e = MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_UP, x, y, 0);sendPointerSync(e);}else if(opt.equals("move")){float x = Float.valueOf(mArgs[1]);float y = Float.valueOf(mArgs[2]);float x2 = Float.valueOf(mArgs[3]);float y2 = Float.valueOf(mArgs[4]);MotionEvent e = MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_DOWN, x, y, 0);sendPointerSync(e);e = MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_MOVE, x, y, 0);sendPointerSync(e);e = MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_MOVE, x, y, 0);sendPointerSync(e);e = MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_MOVE, x2, y2, 0);sendPointerSync(e);e = MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_MOVE, x2, y2, 0);sendPointerSync(e);e = MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_UP, x2, y2, 0);sendPointerSync(e);}else if(opt.equals("key")){int keycode = Integer.valueOf(mArgs[1]);KeyEvent k = new KeyEvent(KeyEvent.ACTION_DOWN,keycode);sendKeySync(k);k = new KeyEvent(KeyEvent.ACTION_UP,keycode);sendKeySync(k);}else if(opt.equals("wait")){int millsecond = Integer.valueOf(mArgs[1]);Thread.sleep(millsecond);}else if(opt.equals("keypress")){int keycode = Integer.valueOf(mArgs[1]);int millsecond = Integer.valueOf(mArgs[2]);KeyEvent k = new KeyEvent(KeyEvent.ACTION_DOWN,keycode);sendKeySync(k);Thread.sleep(millsecond);k = new KeyEvent(KeyEvent.ACTION_UP,keycode);sendKeySync(k);                       }else if(opt.equals("touchpress")){float x = Float.valueOf(mArgs[1]);float y = Float.valueOf(mArgs[2]);int millsecond = Integer.valueOf(mArgs[3]);MotionEvent e = MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_DOWN, x, y, 0);sendPointerSync(e);Thread.sleep(millsecond);e = MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_UP, x, y, 0);sendPointerSync(e);}else System.err.println("** Error: Unknown option: " + opt);}catch (RuntimeException ex){}Thread.sleep(2000);       }private static void sendPointerSync(MotionEvent event) {try {(IWindowManager.Stub.asInterface(ServiceManager.getService("window"))).injectPointerEvent(event, true);} catch (RemoteException e) {}}private static void sendKeySync(KeyEvent event) {try {(IWindowManager.Stub.asInterface(ServiceManager.getService("window"))).injectKeyEvent(event, true);} catch (RemoteException e) {}}}在与java文件同级创建Android.mk文件，内容如下：# Copyright 2008 The Android Open Source Project#LOCAL_PATH:= $(call my-dir)include $(CLEAR_VARS)LOCAL_SRC_FILES := $(call all-subdir-java-files)LOCAL_MODULE := autotestinclude $(BUILD_JAVA_LIBRARY)在终端命令行下进入autotest文件夹，输入mm命令，如果报错，则返回Android源码主目录，输入如下命令：. build/envsetup.sh此时再返回你的工程目录输入mm就可以了，编译生成一个.jar文件，位于源码的/out/target/product/generic/system/framework下将编译好的.jar文件放在设备的/system/framework下，新建一个文件，名称为autotest，内容如下：# Script to start "monkey" on the device, which has a very rudimentary# shell.#base=/systemexport CLASSPATH=$base/framework/autotest.jarexec app_process $base/bin AutoTest $*将autotest文件放在/system/bin下，用chmod修改文件属性（777）这样你可以在shell下调用你的.jar文件了比如输入 shell autotest key 24，向系统注入了调节音量的按键事件。
