Question

首先，让我告诉您到目前为止我做了什么。我经历了很多搜索，包括

firebase_messaging not customizing notification when an app is not in the foreground

此外，我已经引用了GitHub和许多文章，但是这些文章都不对我有用，这就是我发布此问题的原因，所以请不要将此内容标记为重复。

当应用程序运行时，它可以正常工作，但是当应用程序在后台时，它会显示系统通知。

我们是否需要添加custom_notification_layout引用以显示清单？（是否有meta tag或其他内容？）

这是MyFireBaseMessagingService.java类

public class MyFireBaseMessagingServiceTmp extends FirebaseMessagingService {

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        JSONObject jsonObject = new JSONObject(remoteMessage.getData());
        String title = jsonObject.optString("title");
        String message = jsonObject.optString("message");

        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        if (Build.VERSION.SDK_INT >= 26) {
            NotificationChannel channel = new NotificationChannel("my_notifications", "My notifications", NotificationManager.IMPORTANCE_DEFAULT);
            notificationManager.createNotificationChannel(channel);
        }
        RemoteViews remoteViews;
        if (title == "BIG BANG") {
            remoteViews = new RemoteViews(getPackageName(), R.layout.layout_remainder_with_buttons);
        } else {
            remoteViews = new RemoteViews(getPackageName(), R.layout.layout_remainder_no_buttons);
        }
        remoteViews.setTextViewText(R.id.txtTitle, title);
        remoteViews.setTextViewText(R.id.txtMsg, message);

        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, "my_notifications");
        notificationBuilder.setAutoCancel(true);
        notificationBuilder.setCustomBigContentView(remoteViews);
        {
            Intent intentGotIt = new Intent("ACTION_GOT_IT");
            PendingIntent pendingIntentGotIt = PendingIntent.getBroadcast(this, 0, intentGotIt, PendingIntent.FLAG_ONE_SHOT);
            remoteViews.setOnClickPendingIntent(R.id.btnGotIt, pendingIntentGotIt);
        }
        {
            Intent intentSnooze = new Intent("ACTION_SNOOZE");
            PendingIntent pendingIntentSnooze = PendingIntent.getBroadcast(this, 0, intentSnooze, PendingIntent.FLAG_ONE_SHOT);
            remoteViews.setOnClickPendingIntent(R.id.btnSnooze, pendingIntentSnooze);
        }
        notificationBuilder.setSmallIcon(R.mipmap.ic_launcher);
        notificationBuilder.setPriority(Notification.PRIORITY_HIGH);
        notificationBuilder.setAutoCancel(true);
        Bitmap icon = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
        notificationBuilder.setLargeIcon(icon);
        Notification notification = notificationBuilder.build();
        notification.sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        notification.vibrate = new long[]{0, 400, 200, 400};
        notificationManager.notify(1000, notification);
    }
}

Answer 1

从ServerSide

请确保“您正在NOT发送” notification” 中的” notification payload” 字段如果要发送？，然后请从服务器请求中删除notification字段，并仅发送数据。

因为您的应用在后台运行时，Android会NOT执行onMessageReceived，系统将接管该通知并显示“正常通知”。

因此，在通知有效载荷中仅发送“ data”。另外，在您的通知有效内容中添加{"priority": "high"}。

以下是服务器响应的示例

{
  "to": "your_fcm_token",
  "priority": "high",
  "data":{
    "title": "Your title",
    "msg": "your msg",
    "other_info": "etc"
  }
}

希望这会有所帮助：）

当App不在前台或未运行时，Remoteview会显示系统通知，而不是“自定义通知”
