I Couldn't Reach Change Location Value in Android -

i'm sorry mine simple question i'm newbie topic. have location class android , reach mine location toast message couldn't reach mine location value other class. example;

my location class

import android.app.alertdialog; import android.content.context; import android.location.location; import android.location.locationlistener; import android.location.locationmanager; import android.os.bundle; import android.widget.toast;  public class mylocation{     private locationmanager locationmanager;     locationlistener locationlistener;     private context ourcontext;      public mylocation(context context){          this.ourcontext = context;          locationmanager = (locationmanager) context.getsystemservice(context.location_service);         locationlistener = new mylocationlistener();          boolean gps = locationmanager.isproviderenabled(locationmanager.gps_provider);          if(!gps){             locationmanager.requestlocationupdates(locationmanager.network_provider, 6000, 100, locationlistener);             alertdialog alertdialog = new alertdialog.builder(context).create();             alertdialog.settitle("gps disabled");             alertdialog.setmessage("you can enable gps settings");             alertdialog.seticon(r.drawable.ic_launcher);             alertdialog.show();              } else {             locationmanager.requestlocationupdates(locationmanager.gps_provider, 6000, 100, locationlistener);         }      }      public class mylocationlistener implements locationlistener{          @override         public void onlocationchanged(location location) {             // todo auto-generated method stub             bundle bundle = new bundle();              lat = location.getlatitude();             lon = location.getlongitude();             toast.maketext(ourcontext, lat +" ve "+ lon, toast.length_long).show();              bundle.putstring("lat", lat.tostring());             bundle.putstring("lon", lon.tostring());         }          @override         public void onproviderdisabled(string provider) {             // todo auto-generated method stub          }          @override         public void onproviderenabled(string provider) {             // todo auto-generated method stub          }          @override         public void onstatuschanged(string provider, int status, bundle extras) {             // todo auto-generated method stub          }          public string getlat(){             return lat.tostring();         }          public string getlon(){             return lon.tostring();         }          private double lat;         private double lon;     } 

and call

mylocation mylocation = new mylocation(getactivity()); runnable runnable = new runnable() {              @override             public void run() {                 // todo auto-generated method stub                 while(bundle.getstring("lon") != null){                     tv1.settext("lon : " + bundle.getstring("lon"));                     tv2.settext("lat : " + bundle.getstring("lat"));                 }              }         };          new thread(runnable).start(); 

but every time bundle return null value. can ?

because construct new bundle can retrieve datas saved in activity.

you can implement following :

public class mylocationlistener implements locationlistener{     bundle bundle = new bundle();     public bundle getbundle(){         return bundle;    }          @override         public void onlocationchanged(location location) {             // todo auto-generated method stub              lat = location.getlatitude();             lon = location.getlongitude();             toast.maketext(ourcontext, lat +" ve "+ lon, toast.length_long).show();              bundle.putstring("lat", lat.tostring());             bundle.putstring("lon", lon.tostring());         }       //other method  }  public class mylocation{     private locationmanager locationmanager;     locationlistener locationlistener;     private context ourcontext;      public mylocation(context context){          this.ourcontext = context;          locationmanager = (locationmanager) context.getsystemservice(context.location_service);         locationlistener = new mylocationlistener();          boolean gps = locationmanager.isproviderenabled(locationmanager.gps_provider);          if(!gps){             locationmanager.requestlocationupdates(locationmanager.network_provider, 6000, 100, locationlistener);             alertdialog alertdialog = new alertdialog.builder(context).create();             alertdialog.settitle("gps disabled");             alertdialog.setmessage("you can enable gps settings");             alertdialog.seticon(r.drawable.ic_launcher);             alertdialog.show();              } else {             locationmanager.requestlocationupdates(locationmanager.gps_provider, 6000, 100, locationlistener);         }  public bundle getbundle(){   if(locationlistener != null)       return locationlistener.getbundle();    else         return null; }     } 

then :

    bundle bundle = mylocation.getbundle();     if(bundle != null){         tv1.settext("lon : " + bundle.getstring("lon"));         tv2.settext("lat : " + bundle.getstring("lat")); } 

edit :

change private locationlistener locationlistener;

with private mylocationlistener locationlistener;
