I want to implement list view like facebook comments that able to load previous comments on top. Here screenshoot of facebook comments.

enter image description here

So, on facebook app, when I clicked button "Load previous comments" it append data on the first position of the list without changing listView state/position.

In my project I use RecylcerView with loadmore button on the header. On the header, I put "Load Previous button". When the button is clicked, it put new data into the list.

 for (int i = 0; i <= 10; i++) {
     list.add(0, "New data on top");
 }

After new data appended to list, I tried calling notifyDataSetChanged to make change happen, and call smoothScrollToPosition on my recycler view to make it scrolled into the first position before new data added. 

 adapter.notifyDataSetChanged();
 recyclerView.smoothScrollToPosition(10);

But the problem is it scrolling up. So I wanna make RecylerView stay on the last position before new data added just like facebook comment.

Can anybody suggest me how to implement this?

There is the Swipe to refresh layout you might want to use for this. Note however that there is no button but an spinner image that is dismissed automatically.

EDIT: Just realized that this does not answer the question. You might want to check out this post that is a possible duplicate.
