我有两个火对象＆＃34;聊天＆＃34;和＆＃34;消息＆＃34;如下。每个聊天都有消息的列表ID。

我将使用FirebaseRecyclerAdapter为聊天对话显示消息。我的问题是＆＃34; 聊天＆＃34;节点，它只包括列表message_id，内部节点中的真实数据＆＃34;消息＆＃34;。

如何处理此案例以使用FirebaseRecyclerAdapter？（抱歉我的英语不好）

Answer 1

在聊天节点13dc0865-616b-4963-bfdf-6c9b5d2011ef中，您可以访问与其message_ids对应的-KpbG1tnCItaKykzEjaN, -KpbG3cvMwitf_yzdYb6, -KpbG9UhiOBJFR8GPE2x。

现在您可以获取与id对应的消息数据（messages - ＆gt; -KpbG1tnCItaKykzEjaN = your message）。您可以为剩余的消息ID重复此操作。

无法在列表ID的情况下使用FirebaseRecyclerAdapter
