Android--锁屏开盘广播

好像静态注册不了，所以动态注册

		MyReceiver myReceiver= new MyReceiver();
        IntentFilter filter = new IntentFilter();
        //添加action
        filter.addAction("android.intent.action.SCREEN_OFF");
        filter.addAction("android.intent.action.SCREEN_ON");
        //注册广播接收者
        registerReceiver(myReceiver,filter);
