共享相同布局的多个片段

如何解决共享相同布局的多个片段

所以我正在编写一个优惠券应用程序，我想将优惠券分为几类（服装、家庭..）我创建了一个优惠券片段，并在其中使用 tablayout 和 viewpager 添加了多个片段，这些片段假设代表类别。所以这里是我想对所有这些都使用相同的 recyclerview 并且一些与特定类别无关的产品不会出现我想通过使用 setvisibilty 来做到这一点fragment 和 recyclerview 本身以及第二个以便使用 viewpager 添加片段。 如何在所有这些视图中使用相同的 recyclerview 并使用适配器管理它们中的每一个？

这是我的代码，如果有人能提供帮助，我会很高兴
