我正在尝试在推送聊天工具回收器视图中查看所有已加入的房间，但它似乎不起作用。我滚动后它只加载一个房间。当我打开活动时，它显示为空白。此外，当我点击房间时，意图并没有启动，它只是停留在回收站视图上。它应该去选定的聊天室。
通过调试，我可以看到我正在连接到可访问的房间（其中有 7 个）但是似乎只有其中一个被添加到适配器/回收器视图中但是我找不到它的不足之处. 我对 kotlin 比较陌生，这可能会增加这个问题。
这是我正在遵循的教程，我认为开箱即用相对较好，但似乎有一些障碍。
任何和所有的帮助表示赞赏。

应在 Recyclerview 中显示的房间
1)
2)
这是我滚动任何方向后的样子
3)
