this guess not parsing packid while re initializing list after deleting 1 item.
if(person.getstring("responsecode").equals("1")) { jsonarray itemslist=person.optjsonarray("itemlist"); if(itemslist==null) { toast.maketext(buynowactivity.this, "your shopping cart empty", toast.length_short).show(); } else { (int j = 0; j < itemslist.length(); j++) { jsonobject cartitems = itemslist.getjsonobject(j); cartmodel cvm = new cartmodel(); cvm.setcart_product_name(cartitems.getstring("prodnarration")); cvm.setcart_product_price(cartitems.getstring("finalprice")); cvm.setcart_product_id(cartitems.getstring("productid")); cvm.setcart_product_img(cartitems.getstring("packlink")); cvm.setcart_product_qty(cartitems.getstring("qty")); cvm.setcart_product_packdiscount(cartitems.getstring("packdiscdesc")); // here add code parsing packid cartlist.add(cvm); } toast.maketext(buynowactivity.this, "product removed successfully", toast.length_short).show(); } } try adding parsing code have added comment.
hope you.
