推荐答案

此方法适用于高达2.3，

This solution works upto 2.3,

覆盖下面的方法，在你的活动，

Override the below method in your Activity,

@Override
public void onAttachedToWindow() {
    super.onAttachedToWindow();
    this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);           
}

和现在处理这种关键事件，

And now handle the key event like this,

@Override

public boolean onKeyDown(int keyCode, KeyEvent event) {

   if(keyCode == KeyEvent.KEYCODE_HOME)
    {
     Log.i("Home Button","Clicked");
    }
   if(keyCode==KeyEvent.KEYCODE_BACK)
   {

        finish();
   }
return false;

};
