There is no need to call your Activity to referesh listview you can use

notifyDataSetChanged()

remove the item and set notifyDataSetChanged()

yourList.remove([INDEX]);
arrayAdapter.notifyDataSetChanged();

If you are removing a single item from the view, you need to call

yourAdapter.notifyItemChanged(position) //Just pass the position to this. This also has a default animation. Try this in your adapter class instead of refreshing the layout.

Try below lines of code on Deleting Row to Update adapter

 arrayList.remove(position);
 mAdapter.notifyItemRemoved(position);
