Group notification wont show
问题
以下是翻译好的部分：
我正在使用 FCM 在用户收到新消息时发送通知。
我希望从我的应用程序中创建一个分组通知，以便它显示如下：
（图片已省略）
然而，由于某种原因，我收到的每个新通知都会删除其他通知，因此它始终只显示最新的通知。
我的代码如下：
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private FirebaseAuth auth;
private FirebaseFirestore db;
private static String GROUP_KEY = "NOTIFICATION";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
createNotificationChannel();
notifyThis(remoteMessage.getData().get("title"), remoteMessage.getData().get("body"), remoteMessage.getData().get("var1"), remoteMessage.getData().get("var2"), remoteMessage.getData().get("var3"));
}
private void createNotificationChannel() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
CharSequence name = "ABC";
String description = "ABCDE";
int importance = NotificationManager.IMPORTANCE_DEFAULT;
NotificationChannel channel = new NotificationChannel("191919", name, importance);
channel.setDescription(description);
NotificationManager notificationManager = getSystemService(NotificationManager.class);
notificationManager.createNotificationChannel(channel);
}
}
public void notifyThis(String title, String message, String var1, String var2, String var3) {
Intent intent = new Intent(this, ChatActivity.class);
intent.putExtra("ChatID", var1);
intent.putExtra("ReceiverID", var2);
intent.putExtra("itemID", var3);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, "191919")
.setSmallIcon(R.drawable.ic_launcher_custom_background)
.setContentTitle(title)
.setContentText(message)
.setContentIntent(pendingIntent)
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.setGroup(GROUP_KEY)
.setAutoCancel(true);
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
notificationManager.notify(0, mBuilder.build());
}
}
是否有任何原因导致这种情况？是否有可能是因为 channelId？
另外，我看到我可能需要构建多个通知，但是如何根据用户收到的消息数量来动态生成通知呢？
假设我收到了 2 条通知，然后我又收到了一条消息，但我只构建了 2 条通知，它将如何显示第三条通知？
谢谢。

I am using FCM to send notifications between users when they receive a new message.
I had like to make a group notification from my app so it will show like this:
However, for some reason every new notification that I get, it deletes the other so it always shows only the latest notification.
My code is:
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private FirebaseAuth auth;
private FirebaseFirestore db;
private static String GROUP_KEY = "NOTIFICATION";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
createNotificationChannel();
notifyThis(remoteMessage.getData().get("title"),remoteMessage.getData().get("body"),remoteMessage.getData().get("var1"),remoteMessage.getData().get("var2"),remoteMessage.getData().get("var3"));
}
private void createNotificationChannel() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
CharSequence name = "ABC";
String description = "ABCDE";
int importance = NotificationManager.IMPORTANCE_DEFAULT;
NotificationChannel channel = new NotificationChannel("191919", name, importance);
channel.setDescription(description);
NotificationManager notificationManager = getSystemService(NotificationManager.class);
notificationManager.createNotificationChannel(channel);
}
}
public void notifyThis(String title, String message, String var1, String var2, String var3) {
Intent intent = new Intent(this, ChatActivity.class);
intent.putExtra("ChatID",var1);
intent.putExtra("ReceiverID",var2);
intent.putExtra("itemID",var3);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, "191919")
.setSmallIcon(R.drawable.ic_launcher_custom_background)
.setContentTitle(title)
.setContentText(message)
.setContentIntent(pendingIntent)
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.setGroup(GROUP_KEY)
.setAutoCancel(true);
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
notificationManager.notify(0, mBuilder.build());
}
}
Is there any reason? Any chance that it is because of the channelId?
Also, I saw that I might need to build multiple notifications however how can I make it dynamic based on the amount of messages that the user gets?
Lets set I get 2 notifications and then I get one more message but I built only 2 notifications, how it will show me the third?
Thank you
