android - How to recall onCreate( ) when onBackPressed( ) and go to previous activity? -

myapp testing multi language change. http://www.androhub.com/android-building-multi-language-supported-app/ after choose radio button, changes language in current activity. when go previous activity, doesn't change language. so, want recall oncreate when click button. or how refresh current activity?

oncreate ()

@override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main3);      txt = (textview) findviewbyid(r.id.txt);     radiogroup = (radiogroup) findviewbyid(r.id.radiogroup);     radioeng = (radiobutton) findviewbyid(r.id.eng);     radiohi = (radiobutton) findviewbyid(r.id.hi);      // initialization     pref = getsharedpreferences("mypref", activity.mode_private);     editor = pref.edit();      radiogroup.setoncheckedchangelistener(new radiogroup.oncheckedchangelistener() {         @override         public void oncheckedchanged(radiogroup radiogroup, @idres int i) {             string lang = "en"; // default language             switch (i) {                 case r.id.eng:                     lang = "en";                     break;                 case r.id.hi:                     lang = "hi";                     break;                 default:                     break;             }             changelocale(lang); // change locale on selection basis         }     });      loadlocale(); } 

changelocale

private void changelocale(string lang) {     if (lang.equalsignorecase(""))         return;     locale mylocale = new locale(lang); // set selected locale     savelocale(lang);   // save selected locale     locale.setdefault(mylocale);    // set new locale default     configuration config = new configuration(); // configuration     config.locale = mylocale;   // set config locale selected locale     getbasecontext().getresources().updateconfiguration(config, getbasecontext().getresources().getdisplaymetrics());   // update config } 

savelocale & loadlocale

private void savelocale(string lang) {     editor.putstring("save", lang);     editor.commit();     if (lang.equals("en")) {         radioeng.setchecked(true);     } else {         radiohi.setchecked(true);     } }  private void loadlocale() {     string lang = pref.getstring("save", "");     if (lang.equals("")) {         radioeng.setchecked(true);     } else {         changelocale(lang);     } } 

give resultcode when current activity, or save configuration, check configuration on activity resume language change
