android - On clicking button the selected RadioButton state in RadioGroup should saved in SharedPreferences using Fragments -

fragment activity contains radiogroup having 5 radiobuttons , button.radiobutton5 have edittext it.

public void oncreate(bundle savedinstancestate) {      radio1 = preferencemanager.getdefaultsharedpreferences(getactivity()).getboolean("radio1", false);     radio2 = preferencemanager.getdefaultsharedpreferences(getactivity()).getboolean("radio2", false);     radio3 = preferencemanager.getdefaultsharedpreferences(getactivity()).getboolean("radio3", false);     radio4 = preferencemanager.getdefaultsharedpreferences(getactivity()).getboolean("radio4", false);     radio5 = preferencemanager.getdefaultsharedpreferences(getactivity()).getboolean("radio5", false);     str_rbtext = preferencemanager.getdefaultsharedpreferences(getactivity()).getstring("selected_rb_msg", "nomi");     msgtosend = preferencemanager.getdefaultsharedpreferences(getactivity()).getstring("msgtosend", "");     super.oncreate(savedinstancestate); }  @override public view oncreateview(layoutinflater inflater, viewgroup container,                          bundle savedinstancestate) {     // inflate layout fragment     viewroot =  inflater.inflate(r.layout.fragment_messages, container, false);      radiogroup = (radiogroup) viewroot.findviewbyid(r.id.radio_grp);     rb1 = (radiobutton) viewroot.findviewbyid(r.id.rb_msg1);     rb2 = (radiobutton) viewroot.findviewbyid(r.id.rb_msg2);     rb3 = (radiobutton) viewroot.findviewbyid(r.id.rb_msg3);     rb4 = (radiobutton) viewroot.findviewbyid(r.id.rb_msg4);     rb5 = (radiobutton) viewroot.findviewbyid(r.id.rb_custommsg);     edittext = (edittext) viewroot.findviewbyid(r.id.et_custommsg);      if(radio1){         rb1.setchecked(true);     }     else if(radio2){         rb2.setchecked(true);     }     else if(radio3){         rb3.setchecked(true);     }     else if(radio4){         rb4.setchecked(true);     }     else if(radio5){         rb5.setchecked(true);         edittext.setvisibility(view.visible);         edittext.sethint(preferencemanager.getdefaultsharedpreferences(getactivity()).ge tstring("selected_rb_msg", ""));     }      function();     return viewroot; } public void function(){      sharedpreferences sp =  preferencemanager.getdefaultsharedpreferences(getactivity());     final sharedpreferences.editor editor = sp.edit();     if(rb1.ischecked() && !rb5.ischecked() && !rb2.ischecked() &&  !rb3.ischecked() && !rb4.ischecked()){         edittext.setvisibility(view.invisible);     }  radiogroup.setoncheckedchangelistener(new  radiogroup.oncheckedchangelistener() {     @override     public void oncheckedchanged(radiogroup group, int checkedid) {         if (checkedid == r.id.rb_msg1){             str_rbtext = rb1.gettext().tostring();             edittext.setvisibility(view.invisible);             edittext.settext("");             //editor.putboolean("radio1", true).apply();         } else if (checkedid == r.id.rb_msg2){             str_rbtext = rb2.gettext().tostring();             edittext.setvisibility(view.invisible);             edittext.settext("");             //editor.putboolean("radio2", true).apply();         } else if (checkedid == r.id.rb_msg3){             str_rbtext = rb3.gettext().tostring();             edittext.setvisibility(view.invisible);             edittext.settext("");             //editor.putboolean("radio3", true).apply();         } else if (checkedid == r.id.rb_msg4){             str_rbtext = rb4.gettext().tostring();             edittext.setvisibility(view.invisible);             edittext.settext("");             //editor.putboolean("radio4", true).apply();         } else if (checkedid == r.id.rb_custommsg){                 edittext.setvisibility(view.visible);                 edittext.sethint("enter custom message");                 str_rbtext = edittext.geteditabletext().tostring().trim();         }     }); 

onclicking button selected radio button state should save in sharedpreferences , load on starting activity

button btnset = (button) viewroot.findviewbyid(r.id.btn_set_msgfrag);     btnset.setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view v) {             log.e("selectedradiobutton",str_rbtext);              int id = radiogroup.getcheckedradiobuttonid();             if(id == r.id.rb_msg1){                 editor.putboolean("radio1", true).apply();             }else if(id == r.id.rb_msg2){                 editor.putboolean("radio2", true).apply();             }else if(id == r.id.rb_msg3){                 editor.putboolean("radio3", true).apply();             }else if(id == r.id.rb_msg4){                 editor.putboolean("radio4", true).apply();             }else if(id == r.id.rb_custommsg){                 editor.putboolean("radio5", true).apply();             }         }     }); } } 

radiobutton state not stored correctly. state of 1st radiobutton true on getting when calling activity.

when putting 1 state of selected radiobutton put false in other radiobuttons.

radiogroup.setoncheckedchangelistener(new radiogroup.oncheckedchangelistener() {         @override         public void oncheckedchanged(radiogroup group, int checkedid) {             if (checkedid == r.id.rb_msg1){                 str_rbtext = rb1.gettext().tostring();                 edittext.setvisibility(view.invisible);                 edittext.settext("");                 editor.putboolean("radio1", true).apply();                 editor.putboolean("radio2", false).apply();                 editor.putboolean("radio3", false).apply();                 editor.putboolean("radio4", false).apply();                 editor.putboolean("radio5", false).apply();             } else if (checkedid == r.id.rb_msg2){                 str_rbtext = rb2.gettext().tostring();                 edittext.setvisibility(view.invisible);                 edittext.settext("");                 editor.putboolean("radio2", true).apply();                 editor.putboolean("radio1", false).apply();                 editor.putboolean("radio3", false).apply();                 editor.putboolean("radio4", false).apply();                 editor.putboolean("radio5", false).apply();             } else if (checkedid == r.id.rb_msg3){                 str_rbtext = rb3.gettext().tostring();                 edittext.setvisibility(view.invisible);                 edittext.settext("");                 editor.putboolean("radio3", true).apply();                 editor.putboolean("radio1", false).apply();                 editor.putboolean("radio2", false).apply();                 editor.putboolean("radio4", false).apply();                 editor.putboolean("radio5", false).apply();             } else if (checkedid == r.id.rb_msg4){                 str_rbtext = rb4.gettext().tostring();                 edittext.setvisibility(view.invisible);                 edittext.settext("");                 editor.putboolean("radio4", true).apply();                 editor.putboolean("radio1", false).apply();                 editor.putboolean("radio2", false).apply();                 editor.putboolean("radio3", false).apply();                 editor.putboolean("radio5", false).apply();             } else if (checkedid == r.id.rb_custommsg){                 edittext.setvisibility(view.visible);                 edittext.sethint("enter custom message");                 //if(edittext.length() == 0){                 //  toast.maketext(getcontext(), "visible", toast.length_short).show();                 //}                 str_rbtext = edittext.geteditabletext().tostring().trim();                 editor.putboolean("radio5", true).apply();                 editor.putboolean("radio1", false).apply();                 editor.putboolean("radio2", false).apply();                 editor.putboolean("radio3", false).apply();                 editor.putboolean("radio4", false).apply();                 //edittext.setbackgrounddrawable(null);  //to remove underline of edittext             }             editor.putstring("msg2send", str_rbtext).apply();         }     });
