You can do like this way: Create one method in adaptor as below.

 public void swapeItem(int fromPosition,int toPosition){
     Collections.swap(arrayList, fromPosition, toPosition);
     notifyItemMoved(fromPosition, toPosition);
 }

now on item click you can use like this way.

swapeItem(9,0); // here 9 is a clicked item position and 0 means at top of the list.
