               setLocale("en");

               return true;

           case R.id.action_gujarati:

               setLocale("gu");

               return true;

           case R.id.action_hindi:

               setLocale("hi");

               return true;

           case R.id.action_kannada:

           case R.id.action_urdu:

               setLocale("ur");

               return true;

       }

       return super.onOptionsItemSelected(item);

    }

public void setLocale(String lang) {

       Locale myLocale = new Locale(lang);

       Resources res = getResources();

       DisplayMetrics dm = res.getDisplayMetrics();

       Configuration conf = res.getConfiguration();

       conf.locale = myLocale;

       res.updateConfiguration(conf, dm);

       Intent refresh = new Intent(this, MainActivity.class);

       startActivity(refresh);

       finish();

    }

setLocale Method will set user selected language to your application
