In this I have toolbar and below that I have scrollview and inside that scrollview I have many layouts...
我想固定在ViewPager上方(底部)的TabLayout.当我向下滚动时，tabLayout被固定，并且显示了视图寻呼机(看起来类似于tabLayout被固定在工具栏下方).
I want to pin TabLayout which is above the ViewPager (at the bottom). When I scroll down the tabLayout is pinned and the view pager shown(looks something Like tabLayout is pinned below the toolbar).
