orderactivity.java

public class orderactivity extends listactivity {  public arraylist<string> orderlist = new arraylist<string>(); private string[] list; private arrayadapter<string> adapter; private listview lv; private string listitem;  @override   public void oncreate(bundle bundle) {     super.oncreate(bundle);     setcontentview(r.layout.order_screen);      intent = new intent();     listitem = i.getstringextra("sendheader");     // adds received sata arraylist orderlist     orderlist.add(listitem);       // assign lv order_screen's listview component order_list     lv = (listview) findviewbyid(r.id.order_list);      // convert arraylist orderlist array     list = (string[]) orderlist.toarray();      // assign adapter "this" context, layout page order_list_item, , info obtained in list     adapter = new arrayadapter<string>(this, r.layout.order_list_item, list); //r.id.order_food_name);     // set data behing lv adapter     adapter.notifydatasetchanged();     lv.setadapter(adapter);        } 

the problem arraylist declaration gets call each time when u pass intent initialize again , clear last store values don't stored values best way declare arraylist in other class , add received values arraylist , pass adapter.
