Android监听屏幕状态的广播

一、实现屏幕状态的广播

实现代码如下所示：

public class ScreenBroadcastReceiver extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) {String action = intent.getAction();Logger.e("广播Action = " + action);if (action.equals(Intent.ACTION_SCREEN_OFF)) {Logger.e("锁屏");} else if (action.equals(Intent.ACTION_SCREEN_ON)) {Logger.e("解锁");}else if(action.equals(Intent.ACTION_USER_PRESENT)){Logger.e("开屏");}}
}

二、注册屏幕状态的广播

代码如下所示：

ScreenBroadcastReceiver screenBroadcastReceiver = new ScreenBroadcastReceiver();
IntentFilter filter = new IntentFilter();
filter.addAction(Intent.ACTION_SCREEN_OFF);
filter.addAction(Intent.ACTION_SCREEN_ON);
filter.addAction(Intent.ACTION_USER_PRESENT);
getApplicationContext().registerReceiver(screenBroadcastReceiver, filter);
