Android监听设备亮灭屏广播（动态广播代码）

MainActivity中

public class MainActivity extends Activity {private WakeAndLockReceiver wakeAndLockReceiver;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);//注册亮屏和息屏的BroadcastReceiverwakeAndLockReceiver = new WakeAndLockReceiver();IntentFilter intentFilter = new IntentFilter();intentFilter.addAction(Intent.ACTION_SCREEN_ON);intentFilter.addAction(Intent.ACTION_SCREEN_OFF);registerReceiver(wakeAndLockReceiver,intentFilter);}//  继承BroadcastReceiver，实现onReceive()：接收到广播后的处理逻辑class WakeAndLockReceiver extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) {if (intent == null) return;String action = intent.getAction();//actionif (Intent.ACTION_SCREEN_ON.equals(action)) {Log.d("wpz", "onReceive: wake");} else if (Intent.ACTION_SCREEN_OFF.equals(action)) {Log.d("wpz", "onReceive: Lock");} else {return;}}}@Overrideprotected void onDestroy() {super.onDestroy();//取消注册unregisterReceiver(wakeAndLockReceiver);}
}

AndroidManifest.xml中

<!--声明权限-->
<uses-permission android:name="android.permission.WAKE_LOCK" />

结果
