Android FCM通知分组 [英] Android FCM notification grouping

问题描述

我试图为一个聊天应用程序实现FCM通知，并且我想实现类似WhatsApp的通知，通知将按照对话分组。

说当爱丽丝回答与鲍勃的谈话时，鲍勃将收到身体爱丽丝：内容的通知。但是，如果爱丽丝很快回复了对话，鲍勃会得到另一个新的通知，但我只是想将新的回复追加到prev通知上。

我怎么能做到这一点？

解决方案

通知有效载荷中的'tag'：

lockquote

tag可选，字符串

用于替换通知中现有通知的标识符抽屉。
如果未指定，每个请求会创建一个新的通知。
如果已指定，并且具有相同标记的通知已被显示，则新通知会替换通知抽屉中的现有通知。

I was trying to implement FCM notification for a chat app and I want to achieve "WhatsApp-like" notification where the notification will be grouped by conversation.

Say when Alice replied to a conversation with Bob inside, Bob will receive a notification with the body "Alice: the content". But if Alice quickly reply to the conversation again, Bob will get another new notification but I just want to append the new reply onto the prev notification instead.

How can I achieve that?

解决方案

You can use the 'tag' in the notification payload:

tag Optional, string
Identifier used to replace existing notifications in the notification drawer. If not specified, each request creates a new notification. If specified and a notification with the same tag is already being shown, the new notification replaces the existing one in the notification drawer.
