推荐答案

有您的应用程序听我们对 ACTION_SCREEN_OFF 播出。点击此处了解详情

Have your app listen our for the ACTION_SCREEN_OFF broadcast. More information here.

public class ScreenReceiver extends BroadcastReceiver {     

        @Override
        public void onReceive(Context context, Intent intent) {
            if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
                //screen locked                
            } else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
                //screen unlocked   
            }
        }

}

您可能还希望通过为的 ACTION_USER_ preSENT 播出。

You might also want to receive information of when the user gets past the keyguard by registering for the ACTION_USER_PRESENT broadcast.
