如何在重新启动后立即启动锁定屏幕活动？

Question

我想在设备重新启动后与启动通知（如消息、Viber通知、Whatsapp等）并排启动锁定屏幕活动。如何做到这一点？？.我已经制作了一个广播接收器，它接收引导完成操作，然后启动一个服务，该服务再次用intent.action_screen_off和intent.action_screen_on意图过滤器注册相同的接收器，该接收器启动锁定屏幕活动。以下是我的代码：

AndroidManifest.xml

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" ></uses-permission>

<receiver>
       <intent-filter android:priority="2147483647">
            <action android:name="android.intent.action.BOOT_COMPLETED" />
       </intent-filter>
</receiver>

当然我在舱单上声明了服务。

这是我的广播接收器类

public class LockScreenBroadCastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
  Log.d("BroadCastReceiver", "ReceivedIntent");

  if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {

  Intent myIntent = new Intent(context, LockScreenActivity.class);
  myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
  myIntent.addFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT);

  if (!LockScreenActivity.isActivityRunning) {
    context.startActivity(myIntent);
  }else{
    Log.d("BroadCasrReceiver","LockScreenActivity is running");
  }

  }else if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
  Log.v("LockScreenBroadReceiver","boot completed");
  Intent startServiceIntent = new Intent(context,LockScreenService.class);             
  context.startService(startServiceIntent);
 }
}
}

和服务类：

LockScreenBroadCastReceiver broadCastReciever;
public static boolean isRunning;

@Override
public IBinder onBind(Intent intent) {
    return null;
}

@Override
public void onCreate() {
    super.onCreate();
    isRunning = true;
    registerReceiver();
}

@Override
public void onDestroy() {
    super.onDestroy();
    isRunning = false;
    unregisterReceiver(broadCastReciever);
    Log.d("LockScreenReceiver", "ReceiverUnregistered");
    sendBroadcast(new Intent("RestartLockScreenService"));
}

private void registerReceiver(){
    IntentFilter intentFilter = new IntentFilter(Intent.ACTION_SCREEN_OFF);
    intentFilter.addAction(Intent.ACTION_SCREEN_ON);
    broadCastReciever = new LockScreenBroadCastReceiver();
    registerReceiver(broadCastReciever,intentFilter);
    Log.d("LockScreenReceiver", "ReceiverRegistered");
 }
}

您可以像这样在manifist中使用Bootcplate的intentFilter instace：

<action android:name="android.intent.action.USER_PRESENT" />
