java - Set text inside fragment not working after revisiting fragment -

i developing bus time table android app. have 3 fragments. inside first fragment have 2 radio buttons i.e. from malegaon & to malegaon. (malegaon name of place).

if select from malegaon radio button setting text sourceedittext malegaon. , if select to malegaon radio button setting text destinationedittext malegaon.

this condition working fine, when visit fragment first time, if revisit fragment from malegaon radio button selected, sourceedittext blank , destinationedittext has text malegaon.

here snapshot , code first fragment.

after selecting malegaon radio button.

i changing visibility of layout. (source edittext,destination edittext,search button 1 layout)

after revisiting oldstandfragment this.

i checked adding logs everywhere possible. , found after revisiting oldstandfragment, tooldmalegoanradiobutton.setonclicklistner() method getting called.

now want refresh fragment when re-visit or other way solve issue.

you have use sharedpreferences save state of checkbox, try code

    public class stackone extends appcompatactivity {      sharedpreferences prefs;     private radiobutton rbutton1, rbutton2;     private radiogroup rg_containerold;      @override     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.stack_one);          prefs = preferencemanager.getdefaultsharedpreferences(stackone.this);          rbutton1 = (radiobutton) findviewbyid(r.id.fromoldmalegoanradiobutton);         rbutton2 = (radiobutton) findviewbyid(r.id.tooldmalegoanradiobutton);         rg_containerold = (radiogroup) findviewbyid(r.id.rg_containerold);          getselectedradiobutton();          int k = prefs.getint("rb1", 0);         if (k == 1) {             rbutton1.setchecked(true);             sourceedittextfrommalegoanold.settext("");         } else if (k == 2) {             rbutton2.setchecked(true);             sourceedittexttomalegoanold.settext("");         }     }      private void getselectedradiobutton() {          rg_containerold.setoncheckedchangelistener(new radiogroup.oncheckedchangelistener() {             @override             public void oncheckedchanged(radiogroup group, int checkedid) {                  switch (group.getcheckedradiobuttonid()) {                     case r.id.fromoldmalegoanradiobutton:                         prefs.edit().putint("rb1", 1).commit();                         break;                     case r.id.tooldmalegoanradiobutton:                         prefs.edit().putint("rb1", 2).commit();                         break;                 }             }         });     } }
