Try below lines of code on Deleting Row to Update adapter

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

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.

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();
