监听home键

先禁止Home键，再在onKeyDown里处理按键值，点击Home键的时候就把程序关闭，或者随你XXOO。

 

@Override

 public boolean onKeyDown(int keyCode, KeyEvent event)

{ // TODO Auto-generated method stub

  if(KeyEvent.KEYCODE_HOME==keyCode)

    android.os.Process.killProcess(android.os.Process.myPid());

     return super.onKeyDown(keyCode, event);

  }

 

@Override

 publicvoid onAttachedToWindow()

 { // TODO Auto-generated method stub

    this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);

    super.onAttachedToWindow();

 }

 

 

加权限禁止Home键

<uses-permission android:name="android.permission.DISABLE_KEYGUARD"></uses-permission>
