仅在 1 个通知中显示 Firebase 通知

Question

我只想在一个通知中显示 firbase 通知，但每次我通过控制台发送推送通知或我的 Web 服务时都会在不同的通知中自动创建。 即使我不在我的代码中使用通知生成器，并且 android 本身会自动创建通知， 最终我想以收件箱样式创建通知，并在它们下面显示所有消息或标题， 感谢您的回复和帮助!!

enter code here@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    Log.e(MyApplication.LOG_TAG, "remote Message:" + remoteMessage.toString());
    Log.e(MyApplication.LOG_TAG, "remote Message->(Data):" + remoteMessage.getData().toString());
    Log.i(MyApplication.LOG_TAG, "FROM:" + remoteMessage.getFrom());
    Log.i(MyApplication.LOG_TAG, "MessageID:" + remoteMessage.getMessageId());
    Log.i(MyApplication.LOG_TAG, "MessageType:" + remoteMessage.getMessageType());
    Log.i(MyApplication.LOG_TAG, "To:" + remoteMessage.getTo());
    Log.i(MyApplication.LOG_TAG, "SentTime:" + remoteMessage.getSentTime());
    Log.i(MyApplication.LOG_TAG, "Ttl:" + remoteMessage.getTtl());
    Log.i(MyApplication.LOG_TAG, "CollapseKey:" + remoteMessage.getCollapseKey());
    if (remoteMessage.getNotification() != null) {
        fcm.setTag(remoteMessage.getNotification().getTag());
        fcm.setTitle(remoteMessage.getNotification().getTitle());
        fcm.setBody(remoteMessage.getNotification().getBody());
        fcm.setBodyLocalizationKey(remoteMessage.getNotification().getBodyLocalizationKey());
        fcm.setClickAction(remoteMessage.getNotification().getClickAction());
        fcm.setColor(remoteMessage.getNotification().getColor());
        fcm.setIcon(remoteMessage.getNotification().getIcon());

        }

        inboxStyle.addLine(messages.get(i));
    }

您可以将tag用于notification有效负载：

用于替换通知抽屉中的现有通知的标识符。

如果未指定，则每个请求都会创建一个新通知。

如果已指定并且已显示具有相同标记的通知，则新通知将替换通知抽屉中的现有通知。

但请注意，当您从 Firebase 控制台发送消息时，您将无法设置tag的值。

或者您可以自己捆绑通知。
