滚动 recyclerview 执行此论坛中发布的所有内容时无法隐藏工具栏

Question

如标题所示，我无法在滚动回收站视图时隐藏工具栏。我有两个选项卡，里面都有一个 fragmet，里面都有一个 recyclerview

这是我的 XML 代码。每个 recyclerview 都有行 app:layout_behavior="@string/appbar_scrolling_view_behavior" 并且收费栏有标志 app:layout_scrollFlags="scroll|enterAlways|snap"

啊！如果您查看 AppBarLayout，它被包裹在 LinearLayout 中。但是 AppBarLayout 应该永远是 CoordinatorLayout 的直系子代。如果仍然不起作用，请尝试将 RecyclerView 包裹在 NestedScrollView.
