思路: 第一种方案：屏蔽除power外的其他按键，屏蔽状态栏下拉，屏蔽触屏。 代码如下： 需要系统签名： 添加权限:     <uses-permission android:name="android.permission.STATUS_BAR" />     <uses-permission android:name="android.permission.EXPAND_STATUS_BAR" /> package com.example.demo; import android.app.Activity; import android.os.Bundle; import android.view.KeyEvent; import android.view.Menu; import android.util.Log; import android.view.Window; import android.view.WindowManager; import android.app.StatusBarManager; import android.view.MotionEvent; public class MainActivity extends Activity { public static final int FLAG_HOMEKEY_DISPATCHED = 0x80000000; private StatusBarManager mStatusBarManager; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); getWindow().addFlags(FLAG_HOMEKEY_DISPATCHED); //禁止home disableStatusbar();// 禁止状态栏 setContentView(R.layout.activity_main); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. // getMenuInflater().inflate(R.menu.main, menu); return true; } @Override public boolean onTouchEvent(MotionEvent event) { // TODO Auto-generated method stub return true; }     private void disableStatusbar(){         // 第一句是否可以提出去             mStatusBarManager = (StatusBarManager) this.getSystemService(this.STATUS_BAR_SERVICE);         mStatusBarManager.disable(StatusBarManager.DISABLE_EXPAND);     } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { // TODO Auto-generated method stub switch (keyCode) { case KeyEvent.KEYCODE_VOLUME_DOWN: case KeyEvent.KEYCODE_VOLUME_UP: case KeyEvent.KEYCODE_HOME: return true; default: break; } return super.onKeyDown(keyCode, event); } @Override public boolean onKeyLongPress(int keyCode, KeyEvent event) { // TODO Auto-generated method stub switch (keyCode) { case KeyEvent.KEYCODE_VOLUME_DOWN: case KeyEvent.KEYCODE_VOLUME_UP: case KeyEvent.KEYCODE_HOME: return true; default: break; } return super.onKeyLongPress(keyCode, event); } @Override public void onBackPressed() { // TODO Auto-generated method stub // super.onBackPressed(); } } 如此下来，可以模拟除了power外的所有操作。 2： 以上行为，没法屏蔽power，下面方案实现屏蔽power 这里使用了am命令操作. 具体操作：进入cmd 输入adb shell进入终端 am hang 即可。 3：使用apk实现am命令方案: runCommand("am hang");  private boolean runCommand(String command) { java.lang.Process process = null; try { process = Runtime.getRuntime().exec(command); Log.i("lxm", "Runtime"); process.waitFor(); } catch (Exception e) { e.printStackTrace(); Log.i("lxm", "error"); return false; } finally { try { process.destroy(); } catch (Exception e) { } } Log.i("lxm", "finally"); return true; } 需要添加权限:   <uses-permission android:name="android.permission.SET_ACTIVITY_WATCHER" /> 具体代码可以查看activitymanagerserver.java 里面的hang函数。 4:完整apk源码为： AndroidManifest.xml <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"     package="com.example.demo"     android:versionCode="1"     android:versionName="1.0" >     <uses-sdk         android:minSdkVersion="8"         android:targetSdkVersion="18" />     <uses-permission android:name="android.permission.STATUS_BAR" />     <uses-permission android:name="android.permission.EXPAND_STATUS_BAR" />     <uses-permission android:name="android.permission.SET_ACTIVITY_WATCHER" />     <application         android:allowBackup="true"         android:icon="@drawable/ic_launcher"         android:label="@string/hello_world" android:screenOrientation="portrait"         android:theme="@style/AppTheme" >         <activity             android:name="com.example.demo.MainActivity"             android:label="@string/app_name" >             <intent-filter>                 <action android:name="android.intent.action.MAIN" />                 <category android:name="android.intent.category.LAUNCHER" />             </intent-filter>         </activity>     </application> </manifest> MainActivity.java package com.example.demo;

java.lang.Process process = null;            runCommand("am hang");  } private boolean runCommand(String command) { java.lang.Process process = null; try { process = Runtime.getRuntime().exec(command); Log.i("lxm", "Runtime"); process.waitFor(); } catch (Exception e) { e.printStackTrace(); Log.i("lxm", "error"); return false; } finally { try { process.destroy(); } catch (Exception e) { } } Log.i("lxm", "finally"); return true; } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. // getMenuInflater().inflate(R.menu.main, menu); return true;
