1、AndroidManifest.xml?加入权限

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

2、重写onAttachedToWindow方法

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

3、重写onKeyDown方法
?
@Override
public?boolean?onKeyDown(int?keyCode,?KeyEvent?event)?{
????
???? //?Home键监听
???? if(keyCode?==?KeyEvent.KEYCODE_HOME)?{
???? System.out.println("监听到了Home键....");
???? }
return?super.onKeyDown(keyCode,?event);
}
