android - How to add an id to an arraylist -

i have simple structure of app, downloads mysql data , displays list view. code snippet shows i'm doing.

public class myactivity extends activity implements adapterview.onitemclicklistener {     private static final string tag = "centractivity";      listview listview;     arraylist<string> randomcentr;      @override     public void oncreate(bundle savedinstancestate)     {         super.oncreate(savedinstancestate);         setcontentview(r.layout.main);          parsejson();          arrayadapter adapter = new arrayadapter<string>(this, android.r.layout.simple_list_item_1, randomtorgcentr);         listview = (listview) findviewbyid(r.id.list);         listview.setadapter(adapter);         listview.setchoicemode(listview.choice_mode_none);         listview.setonitemclicklistener(this);     }      private arraylist<string> parsejson() {         randomcentr = new arraylist<string>();          jsonarray centr = null;          //url         string url = "";          jsonparser jsonparser = new jsonparser();          jsonobject jsonobject = jsonparser.getjsonfromurl(url);         log.i(tag, jsonobject.tostring());         try {             torgcentr = jsonobject.getjsonarray("callback");             log.i(tag, torgcentr.tostring());             (int i=0; i<torgcentr.length(); i++) {                 jsonobject o = torgcentr.getjsonobject(i);                 string id = o.getstring("id");                 string name = o.getstring("name");                 randomcentr.add(i, name);                 log.i(tag, randomtorgcentr.get(i));             }         } catch (jsonexception e) {             e.printstacktrace();         }         return randomtorgcentr;     }      @override     public void onitemclick(adapterview<?> parent, view view, int position, long id) {         log.i(tag, randomcentr.get(position));     } } 

everything displaying, have problem. have tables connected 1 id. have name attribute of table in list. so, how specify each element it's id json file, make new request, based on element's id , display detailed data of element??

i suggest create model data , extend baseadapter , create collections of models mapped it. option create simple map , have index key , id value. recommend go first option.
