java - Navigating back to a viewpager fragment in a nested fragment -

i have viewpagercontainer fragment loads when app starts. viewpagercontainer fragment adds 2 tabs(tab , tab b) actionbar. tab b has listview of 2 items.

what have done: attached click listener list view item in tab b fragment such when user clicks on item opens fragment (child fragment) inside first fragment i.e under tab b.

where got stuck: i'd go tab b when user presses button. tried implementing adding child fragment backstack, unfortunately not go tab b fragment. kindly me out have done alot of research on including implementing backstack hacks no success.

i using v4 , v7 appcompat libraries.

any me appreciated. in advance.

edited: managed navigate child fragment actionbar tabs. achieved through following code:

//used getchildfragmentmanager() instead of getsupportfragmentmanager() fragmentmanager fm = getchildfragmentmanager();

myfragmentpageradapter fragadapter = new myfragmentpageradapter(fm);

viewpager.setadapter(fragadapter);

however, on navigation number of tabs double , 2 of them clickable , can see content. when click on listitem on second tab again navigate back, 2 more tabs added , goes on , on. how can solve this? here code

tab b fragment: public class findstylist extends listfragment {

string[] selectcat = {         "category a",         "category b" };  private listview listview; string mtime; public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate){ 

arrayadapter myadapter = new arrayadapter(inflater.getcontext(), android.r.layout .simple_list_item_1, selectcat){

        public view getview(int position, view convertview, viewgroup parent){              view view = super.getview(position, convertview, parent);              textview tv = (textview) view.findviewbyid(android.r.id.text1);              tv.settextcolor(color.black);             tv.setgravity(gravity.center);              return view;              //listview = view.getlistview();          }     };      setlistadapter(myadapter); 

return super.oncreateview(inflater, container, savedinstancestate);

} 

public void onviewcreated(view view, bundle savedinstancestate){

     listview = getlistview();             listview.setonitemclicklistener(new onitemclicklistener(){                 public void onitemclick(adapterview<?> parent, view view, int position, long id){                     if(position == 0){                         //best clicked                         toast.maketext(getactivity(), " cata clicked " + position, 5).show();                      }else if(position == 1){                         //nearest clicked                         toast.maketext(getactivity(), "catb clicked " + position, 5).show();                          fragmentnearest fragment = new fragmentnearest();                         getactivity().getsupportfragmentmanager().begintransaction()                         .replace(r.id.maincontent, fragment)                         .addtobackstack(null)                         .commit();                     }                  }             }); } 

}

child fragment of b:

public class fragmentnearest extends listfragment{

string[] selectlocation = {"from current location", "choose location"}; 

private listview listview;

public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate){ 

arrayadapter myadapter = new arrayadapter(inflater.getcontext(), android.r.layout .simple_list_item_1, selectlocation){

        public view getview(int position, view convertview, viewgroup parent){              view view = super.getview(position, convertview, parent);              textview tv = (textview) view.findviewbyid(android.r.id.text1);              tv.settextcolor(color.black);             tv.setgravity(gravity.center);              return view;          }     };      setlistadapter(myadapter);      return super.oncreateview(inflater, container, savedinstancestate);  } 

you should override onbackpressed method in activity class this.

    @override     public void onbackpressed()     {         if (icanbacktofragment)         {             popbackstackorwhateveryouusetoback()         }         else         {             super.onbackpressed();         }     }
