广播接收器未接收意图（RemoteViews/PendingIntent）

                boolean isPlugged;

                unregisterReceiver(mBatInfoReceiver);

//Starting Notification Service
        notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        remoteViews = new RemoteViews(getPackageName(),R.layout.notification_bar);

    //for getting battery percentage (shows notification)
        this.registerReceiver(this.mBatInfoReceiver, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
    
              

通知广播接收机：

public class Notification_Receiver extends BroadcastReceiver {

String notification_flashlight, notification_sos, notification_delete;

@Override
public void onReceive(Context context, Intent intent) {

    notification_flashlight = intent.getExtras().getString("notification_flashlight");
    notification_sos = intent.getExtras().getString("notification_sos");
    notification_delete = intent.getExtras().getString("notification_delete");

    if (notification_flashlight != null) {

        Toast.makeText(context, "Flashlight", Toast.LENGTH_SHORT).show();
    }

    else if (notification_sos != null) {

        Toast.makeText(context, "SOS", Toast.LENGTH_SHORT).show();
    }

    else if (notification_delete != null) {

        Toast.makeText(context, "Delete", Toast.LENGTH_SHORT).show();
       
    }
}

谁能帮帮我吗？我不知道我做错了什么

我张贴答案，这样它也会帮助其他人。我对广播接收器使用了隐式意图，这是Android奥利奥不建议的。所以，我必须使用明确的意图，然后它开始运作良好。

manifest.xml：

<receiver android:name="com.appedia.flashlight.torch.Notification_Receiver" />

MainActivity.java：

public void NotificationItemsClickIntent()
{
    Intent notification_intent = new Intent(this, MainActivity.class);
    pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, notification_intent, 0);

    Intent notification_deleted_intent = new Intent(this, Notification_Receiver.class);
    notification_deleted_intent.putExtra("notification_delete", "notification_delete");
    delete_pending_intent = PendingIntent.getBroadcast(this, 1, notification_deleted_intent, PendingIntent.FLAG_UPDATE_CURRENT);

    /* Pending Intent for Notification Flashlight Button */
    //Intent with flashlight button for triggering Broadcast Receiver when clicked from notification bar
    Intent notification_flashlight_intent = new Intent(this, Notification_Receiver.class);
    notification_flashlight_intent.putExtra("notification_flashlight", "Flashlight");
    PendingIntent notification_flashlight_button = PendingIntent.getBroadcast(this,2,notification_flashlight_intent,PendingIntent.FLAG_UPDATE_CURRENT);
    remoteViews.setOnClickPendingIntent(R.id.notification_flashlight_button, notification_flashlight_button);

    /* Pending Intent for Notification SOS Button */
    //Intent with sos button for triggering Broadcast Receiver when clicked from notification bar
    Intent notification_sos_intent = new Intent(this, Notification_Receiver.class);
    notification_sos_intent.putExtra("notification_sos", "SOS");
    PendingIntent notification_sos_button = PendingIntent.getBroadcast(this,3,notification_sos_intent,PendingIntent.FLAG_UPDATE_CURRENT);
    remoteViews.setOnClickPendingIntent(R.id.notification_sos_button, notification_sos_button);
}
