}

使用，在onCreate()中设置

@Overridepublic void onCreate() {super.onCreate();mScreenListener = new ScreenReceiverUtil(this);//锁屏广播监听器mScreenListener.setScreenReceiverListener(mScreenListenerer);}private ScreenReceiverUtil.SreenStateListener mScreenListenerer = new ScreenReceiverUtil.SreenStateListener() {@Overridepublic void onSreenOn() {Log_Ma.e(TAG, "开屏 -------------------");}@Overridepublic void onSreenOff() {Log_Ma.e(TAG, "锁屏 ");}@Overridepublic void onUserPresent() {Log_Ma.e(TAG, "解锁 ");}@Overridepublic void pressHome() {Log_Ma.e(TAG, "------------------------------------------------按下home键----------");}@Overridepublic void pressMultitask() {Log_Ma.e(TAG, "------------------------------------------------按下多任务键----------");}};

同时要记得，在onDestroy()中销毁注册信息

mScreenListener.stopScreenReceiverListener();
