Add the new items display top of position in Recycler View

Question

If I add new Item to wishlist RecyclerView can added only at last row, but i want to display at top of 0th position in RecyclerView. I tried to display first position of RecyclerView, but Its doesn't workout well.

Code

 data.add(new CartitemModel(prodcutname, product_alias, MRPPRICE, SALES, OFFER, imagone, productid));
 wishadapter = new WishlistAdapter(data, wishlist_Items.this);
 recyleitems.setAdapter(wishadapter);
 wishadapter.notifyItemInserted(0);

You have a list of items. When you want to add another item to the top use

  data.add(0,new CartitemModel(prodcutname, product_alias, MRPPRICE, SALES, OFFER, imagone, productid));
  wishadapter.notifyItemInserted(0);

This will work as now you are adding the item to top of list.

did I use wishadapter.notifydatasetchaged() – Nivethitha May 25 '16 at 06:48
It's added the second position – Nivethitha May 25 '16 at 06:52
Unless you are inverting your recycer Layout manager this wont happen. – Ragesh Ramesh May 25 '16 at 07:09
But, I have doubt if I attached the adapter in volley It may cause null pointer exception – Nivethitha May 25 '16 at 08:43
Why are you creating new adapter after volley completes? Create it before hand with empty data. Then you can just add the new items to data and call wishadapter.notifyDataSetChanged(); – Ragesh Ramesh May 25 '16 at 12:35
