android - Radio Button setOnChangeListener not working inside fragment -

i want check whether radio button checked do. inside fragment not working cannot figure out because of why? if 1 can appreciate much!

my fragment:

public class onefragment extends fragment {  radiogroup radiofanstatus; radiobutton radiobuttonon; radiobutton radiobuttonoff; view inflateview; tabdisplay tabdisplay; public onefragment() {     // required empty public constructor }  @override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate); }  @override public view oncreateview(layoutinflater inflater, viewgroup container,                          bundle savedinstancestate) {     // inflate layout fragment    inflateview=inflater.inflate(r.layout.fragment_one, container, false);     radiofanstatus = (radiogroup)inflateview.findviewbyid(r.id.radioonoff);    radiobuttonon=(radiobutton)inflateview.findviewbyid(r.id.radiofanon);    radiobuttonoff=(radiobutton)inflateview.findviewbyid(r.id.radiofanoff);          radiofanstatus.setoncheckedchangelistener(new radiogroup.oncheckedchangelistener()         {          @override         public void oncheckedchanged(radiogroup group, int checkedid) {             toast.maketext(getcontext(),"on",toast.length_short).show();           // log.e("",""+checkedid);             toast.maketext(getcontext(),"on"+checkedid+"",toast.length_short).show();              // checkedid radiobutton selected            if(checkedid ==r.id.radiofanon)            {                toast.maketext(getcontext(),"on"+checkedid+"",toast.length_short).show();                 ((tabdisplay)getactivity()).functionfanon();                  log.e("","on");            }            else  if(checkedid ==r.id.radiofanoff)            {                toast.maketext(getcontext(),"off"+checkedid+"",toast.length_short).show();                ((tabdisplay)getactivity()).functionfanoff();                 log.e("","off");            }            else            {             }         }    });     return inflater.inflate(r.layout.fragment_one, container, false); }  } 

this xml related fragment:

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingbottom="@dimen/activity_vertical_margin" android:paddingleft="@dimen/activity_horizontal_margin" android:paddingright="@dimen/activity_horizontal_margin" android:paddingtop="@dimen/activity_vertical_margin" >  <textview     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:text="change staus"     android:textsize="40dp"     android:layout_centerinparent="true"/>  <radiogroup     android:id="@+id/radioonoff"     android:layout_width="wrap_content"     android:layout_height="wrap_content" >      <radiobutton         android:id="@+id/radiofanon"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="on"         />      <radiobutton         android:id="@+id/radiofanoff"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="off" />   </radiogroup> 

try change

return inflater.inflate(r.layout.fragment_one, container, false); 

to

return inflateview; 

now inflating layout twice.
