How to change selected item position to top in Recyclerview?

Question

I have recyclerview in that I want to change item's position dynamically to top after selecting the item of recyclerview.

Please suggest best way to achieve the above problem?

Answer 1

You need to swap selected item with top item in list, then notify your adapter about position change. A sample code would look like:

Collections.swap(orderItems.getItems(), position, 0);
                notifyItemMoved(position, 0);

Hope it helps!

Answer 2

Try this

String Item = List.get(position); 
List.remove(position);  // remove item from the list
List.add(0,removedItem); // add at 0 index of your list
notifyDataSetChanged();
linearLayoutManager.scrollToPositionWithOffset(0, 20); // scroll recyclerview to top 

OR

recyclerview.getLayoutManager().scrollToPosition(0)  // scroll recyclerview to top 

OR

recyclerview.smoothScrollToPosition(0);  // scroll recyclerview to top
