adapter list

public class  orderlistadapter extends baseadapter {         layoutinflater minflater;         public orderlistadapter() {             minflater = layoutinflater.from(listfragmentactivity.this);         }         @override         public int getcount() {             return orderlist.size();         }         @override         public object getitem(int position) {             return null;         }         @override         public long getitemid(int position) {             return position;         }         @override         public view getview(final int position, view convertview, viewgroup parent) {             if (convertview == null) {                 convertview = minflater.inflate(r.layout.listproduct1, null);             }              final textview _id = (textview) convertview.findviewbyid(r.id.proid);             _id.settext("" + orderlist.get(position).get_id());             final string proid = _id.gettext().tostring();              final textview productcode = (textview) convertview.findviewbyid(r.id.productcode);             productcode.settext("" + orderlist.get(position).getproductcode());              final textview description = (textview) convertview.findviewbyid(r.id.description);             description.settext("" + orderlist.get(position).getdescription());              final textview price = (textview) convertview.findviewbyid(r.id.price);         price.settext("" + string.format("%.2f",orderlist.get(position).getprice()));         final double price= double.valueof(price.gettext().tostring());          final textview qty = (textview) convertview.findviewbyid(r.id.qty);         qty.settext("" + orderlist.get(position).getqty());          final textview condimentdescription=(textview)convertview.findviewbyid(r.id.condimentdescription);         condimentdescription.settext("" + orderlist.get(position).getcondimentdescription());          notifydatasetchanged();         return convertview;     } }

every time should create new object of orderlist in do-while loop . remove top of function .
