我有一个初始的recyclerview，用于查看注释，我可以通过扩大布局从Firebase数据库中检索这些注释。夸张的布局还有另一个recyclerview，用于评论评论。目前，我能够在数据库中成功保存对评论的答复。我的问题是我如何才能在“ Comments inflated layout” recyclerview中检索对评论的答复。回复的recyclerview位于注释的第一个初始放大布局内。
This image recyclerview is for the comments
this is the inflated layout for comments with the recyclerview for replies
this is the supposed inflated layout which should be inflated for the replies
下面是我的代码
