Question

所以我试图在Android上创建FCM抬头通知（通过后端调用）。显示通知的代码如下（我在通知时发送数据，因此它将始终调用onMessageReceived）

 intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(),
            new Random().nextInt(), intent,
            PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){
        NotificationChannel channelId = new NotificationChannel("channel01", "name",
            NotificationManager.IMPORTANCE_HIGH);
        channelId.setDescription("test push notif");
        // Register channel with system
        notificationManager.createNotificationChannel(channelId);
    }

    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notificationBuilder =
            new NotificationCompat.Builder(this, "channel01")
                    .setSmallIcon(R.mipmap.ic_collection)
                    .setContentTitle(data.get("title"))
                    .setContentText(data.get("message"))
                    .setAutoCancel(true)
                    .setSound(defaultSoundUri)
                    .setOnlyAlertOnce(true)
                    .setFullScreenIntent(pendingIntent, true)
                    .setDefaults(Notification.DEFAULT_ALL)
                    .setPriority(NotificationCompat.PRIORITY_HIGH);


    notificationManager.notify(99 /* ID of notification */, notificationBuilder.build());

这是我发送的数据

"to":"token-id",
"content_available": true,
"priority": "high",
"data": {
    "title":"title",
  "message": "message body",
  "notificationKey":"1",
  "priority": "high",
  "sound": "default"
}

我的测试设备是Android Pie，因此我需要创建频道以使用Heads-Up。但是，抬头永远不会隐藏，它始终会显示出来，直到单击它或打开系统托盘为止。我希望平视显示像其他任何平视通知一样，在5秒钟内隐藏到系统托盘中。我已经尝试过这些

.setOngoing(true)
.setCategory(Notification.CATEGORY_CALL)

但没有任何区别，除非单击，否则Heads Up通知仍会无限显示。大约5秒钟后，如何隐藏平视提示？

Android FCM抬头通知永远不会隐藏在系统任务栏中
