Android: How to parse JSON file with Gson Library -

i have code parse json file in raw folder. encountering problem method parse_ssid(ssid) not being called , getting @ moment 0 in xml file?!

i getting result ssid variable. since mapping variable in json file, have parse route_number value of it.

this part of method.

if (updatedresults.size() > 0) {     string ssid = deliverbestaccesspoint(updatedresults);     //retrieve data json string , parse it.     int route_number = parse_ssid(ssid); // here getting in xml file 0 , cursor not being jumped "parse_ssid" method.     textwifi.settext(string.valueof(route_number)); } 

parse_ssid method:

private int parse_ssid(string ssid) {             int route_number=0;       inputstream raw =  getresources().openrawresource(r.raw.ssid_number);          reader rd = new bufferedreader(new inputstreamreader(raw));          gson gson = new gson();                      wifijsonlist obj = gson.fromjson(rd, wifijsonlist.class);         // iterate through list         list<wifijson> wifijson = obj.getwifilist();         iterator iterator = wifijson.iterator();         while (iterator.hasnext()) {             wifijson wifielement = (wifijson) iterator.next();             string ssid_name = wifielement.getssid();               if(ssid_name.equals(ssid)){              route_number = wifielement.getroute_number();              }         }            return route_number;      } 

wifijsonlist class:

import java.util.arraylist;  public class wifijsonlist {     private arraylist<wifijson> data;      public arraylist<wifijson> getwifilist() {         return data;     }     public void setwifilist(arraylist<wifijson> wifilist) {         this.data = wifilist;     } } 

wifijson class:

 public class wifijson {         private string ssid;         private int route_number;          public wifijson(string ssid, int route_number) {             this.ssid = ssid;             this.route_number = route_number;          }          public string getssid() {             return ssid;         }          private void setssid(string ssid) {             this.ssid = ssid;         }          public int getroute_number() {             return route_number;         }          private void setroute_number(int route_number) {             this.route_number = route_number;         }          @override         public string tostring() {             return "wifijson [ssid=" + ssid + ", route_number=" + route_number                     + "]";         }       }
