将项目粘贴到 recyclerview 的顶部

Question

I have already read many question on SO and Google regarding Sticky headers in a recyclerview. However, most of them sticks the complete list item on top. I just want to stick part of my list item to top of recyclerview until the complete item is scrolled. I have gone through some libraries such as this one but still not able to figure out how to get it done. Any help is appreciated.

I want to stick the content which is highlighted in the red box until the complete list item (marked in green) is scrolled.

So you want to stick just a part of your list item link this?

Check out this library

Combine with this RecyclerView Adapter library:

Try this!!

This will make the selected(item position) item to stick on top view

recyclerView.setAdapter(adapter);
recyclerView.scrollToPosition(item_posotion);
adapter.notifyDataSetChanged();
