根据以下评论，我更改了layout。它工作正常，但当我转到recyclerview中的项目底部并尝试向上滚动时，它只会上升到recyclerview的开头。我必须再次滚动才能转到header。

我认为你做错了。不需要在RecyclerView项目中添加TabLayout。
你的代码应该是这样的
<android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.AppBarLayout>
<android.support.design.widget.CollapsingToolbarLayout>
<YourHeaderLayout />
<android.support.design.widget.TabLayout />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<RecyclerView />
<!-- OR -->
<ViewPager />
</android.support.design.widget.CoordinatorLayout>
此处如果您显示RecyclerView，则需要在按Tab键上更改LayoutManager。或者您可以在RecyclerView中放置两个ViewPager列表和网格。
