Android query can't store class variable from json object callback -


i can't write class variable ajax-json callback. show right info inside callback when aquery callback finish, set null. why? code:

public void asyncjson() {

    string url = "myurl";     aq.ajax(url, jsonobject.class, new ajaxcallback<jsonobject>() {         @override         public void callback(string url, jsonobject json, ajaxstatus status         {              if (json != null) {                 jsontostring(json);             } else {                 toast.maketext(aq.getcontext(), "error:" + status.getcode(), toast.length_long).show();             }         }     });  private void jsontostring(jsonobject data) {     jsonarray array = null;     try {         array = data.getjsonarray("listresp");         (int = 0; < array.length(); i++) {             jsonobject json_data = array.getjsonobject(i);              c.setdate_creation(json_data.getstring("date_creation"));             c.setname_user(json_data.getstring("name_user"));              list.add(c);//linkedlist         }     } catch (jsonexception e) {         toast.maketext(getapplicationcontext(), e.getmessage(), toast.length_long).show();     } }
