Question

我正在制作一个布局，其中我的TabLayout介于某些内容之间，并且应该在滚动时到达顶部时粘贴到顶部（在工具栏下方）。以下是我的布局xml

我也尝试过如上所述的StickyItemView https://github.com/emilsjolander/StickyScrollViewItems/issues/27库，但它不适合我，因为我很难重新定向像TabLayout这样的粘贴视图之间的触摸和动作事件。我将在Tabs下面的ViewPager中使用Recycler视图。如何在TabLayout的滚动粘贴上实现这一点？任何帮助将不胜感激。

Answer 2

因此，如果我理解你要做的是在顶部有一些静态标签，并在它的底部有一些recyclerview？然后，您不需要使用scrollview封装recyclerview，因为recyclerview带有自己的滚动。你能发布你想要实现的目标吗？
