android - Reload the Fragment is not Working -

i have following situation: navigationdrawer creates fragment handle user information. fragment on oncreateview() calls web service , return view. when web services finishes callsback fragment detach , attach itself. when fragment attached second time on oncreateview() should create view user information. in fact happening view not change.

what missing?

thank in advance,

fragment code:

private boolean misrefresh = false;  @override public view oncreateview(layoutinflater inflater, viewgroup container,                          bundle savedinstancestate) {      // gets application context     mcontext = getactivity().getapplicationcontext();      // set environment use database     mglobal = (global) getactivity().getapplicationcontext();     mdaofactory = mglobal.getdaofactory();      mfragment = this;      mfragmentview = inflater.inflate(r.layout.fragment_user_info, container, false);       buildview();      if (misrefresh) {         return mfragmentview;     }else {         return null;     } } 

here buildview() code:

private void buildview() {      metusername = (edittext) mfragmentview.findviewbyid(r.id.username);     metuseremail = (edittext) mfragmentview.findviewbyid(r.id.useremail);     metpassword = (edittext) mfragmentview.findviewbyid(r.id.password);     metpasswordconfirmation = (edittext) mfragmentview.findviewbyid(r.id.passwordconfirmation);     mibsendpassword = (imagebutton) mfragmentview.findviewbyid(r.id.sendpassword);     macusercountry = (autocompletetextview) mfragmentview.findviewbyid(r.id.usercountry);     metuserstate = (edittext) mfragmentview.findviewbyid(r.id.userstate);     metusercity = (edittext) mfragmentview.findviewbyid(r.id.usercity);     metuserphonenumbercountry = (edittext) mfragmentview.findviewbyid(r.id.userphonenumbercountry);     metuserphonenumbercity = (edittext) mfragmentview.findviewbyid(r.id.userphonenumbercity);     metuserphonenumber = (edittext) mfragmentview.findviewbyid(r.id.userphonenumber);     mcbtcaccepted = (checkbox) mfragmentview.findviewbyid(r.id.cbtcaccepted);       // user has not been created     if (mglobal.getuseruid() == 0) {         getuseremail();         getuserlocation();      } else {         if (misrefresh) {             formatview();         } else {             getdataonserver();         }     }  } 

here code web service called:

private void getdataonserver () {      muserdao = mdaofactory.getuserdao(mcontext);      final progressdialog progressdialog = progressdialog.show (getactivity(),             getstring(r.string.msgconnectingserver), getstring(r.string.msggettingdata), true);      //todo retirar o set abaixo     mglobal.setuseruid(1);      muserdao.getuserbyuid(mglobal.getuseruid(), new callback<user>() {         @override         public void success(user user, response response) {             muser = user;             misrefresh = true;             refresh();         }          @override         public void failure(retrofiterror error) {             muser = null;             log.e(getclass().getname(), "retrofit error = " + error);             refresh();         }          private void refresh() {             progressdialog.dismiss();             fragmentmanager fm = getfragmentmanager();             fragmenttransaction ft = fm.begintransaction();             ft.detach(mfragment)                     .attach(mfragment)                     .commit();          }     }); } 

finally onstart()

@override public void onstart() {     super.onstart();      if (misrefresh) {         misrefresh = false;         getfragmentmanager().begintransaction()                 .remove(mfragment)                 .add(r.id.content_frame, mfragment)                 .commit();     }  } 

instead of

fragmentmanager fm = getfragmentmanager(); fragmenttransaction ft = fm.begintransaction(); ft.detach(mfragment).attach(mfragment).commit(); 

do this:

    yourfragment mfragment = getsupportfragmentmanager().findfragmentbytag("your_fragment_tag"); //if using support library      //or    yourfragment mfragment = getfragmentmanager().findfragmentbytag("your_fragment_tag"); //if using support library      fragmentmanager fm = getfragmentmanager();     fragmenttransaction ft = fm.begintransaction();     ft.detach(mfragment);     ft.attach(mfragment).commit();
