android - Setting Custom Text in DialogFragment -

good morning guys, quite long time i'm trying show custom text in dialogfragment, still got nothing, have multiple tabs inside acitivty extends fragmentactivity , implements tablistener, here how call dialog:

 @override public boolean onoptionsitemselected(menuitem item) {      switch (item.getitemid()) {      case r.id.action_contact:         quickcontactfragment dialog = new quickcontactfragment();         dialog.show(getsupportfragmentmanager(), "quickcontactfragment");         return true;      }      return super.onoptionsitemselected(item); } 

and here dialog body:

 public class quickcontactfragment extends dialogfragment { view view; private pagerslidingtabstrip tabs; private viewpager pager; private contactpageradapter adapter;  public static quickcontactfragment newinstance() {     quickcontactfragment f = new quickcontactfragment();     return f;   }  @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle   savedinstancestate) {        if (getdialog() != null) {         getdialog().getwindow().requestfeature(window.feature_no_title);   getdialog().getwindow().setbackgrounddrawableresource(android.r.color.transparent);       }      view root = inflater.inflate(r.layout.fragment_quick_contact, container,   false);      tabs = (pagerslidingtabstrip) root.findviewbyid(r.id.tabs);     pager = (viewpager) root.findviewbyid(r.id.pager);     adapter = new contactpageradapter();      pager.setadapter(adapter);      tabs.setviewpager(pager);      return root; }   @suppresswarnings("deprecation") @override public void onstart() {       super.onstart();      // change dialog width     if (getdialog() != null) {          int fullwidth = getdialog().getwindow().getattributes().width;          if (build.version.sdk_int >= build.version_codes.honeycomb_mr2) {             display display =   getactivity().getwindowmanager().getdefaultdisplay();             point size = new point();             display.getsize(size);             fullwidth = size.x;         } else {             display display =   getactivity().getwindowmanager().getdefaultdisplay();             fullwidth = display.getwidth();         }          final int padding = (int)    typedvalue.applydimension(typedvalue.complex_unit_dip, 24, getresources()                 .getdisplaymetrics());          int w = fullwidth - padding;         int h = getdialog().getwindow().getattributes().height;          getdialog().getwindow().setlayout(w, h);     } }  public class contactpageradapter extends pageradapter implements icontabprovider {      private final int[] icons = { r.drawable.ic_launcher_gplus,   r.drawable.ic_launcher_gmail,             r.drawable.ic_launcher_gmaps,    r.drawable.ic_launcher_chrome };      public contactpageradapter() {         super();     }   //here implemention      //here shows how many tabs should predict.. can set n=0 , every   time notification comes, set n=n+1, , whenever delete happenes, n=n-1 ;d     @override     public int getcount() {         return icons.length;     }  ////this implemented method icontabprovider.. figure set image   on if   down there,        @override     public int getpageiconresid(int position) {           return icons[position];     }      @override     public object instantiateitem(viewgroup container, int position) {         // looks little bit messy here         textview v = new textview(getactivity());         v.setbackgroundresource(r.color.background_window);         if (position == 2){             v.settext("this page 3 :d");   textview tv =(textview)getactivity().findviewbyid(r.id.quickcontacttext);   tv.settext("have heared it? bieber  pragnent !");         }         else{         v.settext("page " + (position + 1));   }            final int padding = (int)     typedvalue.applydimension(typedvalue.complex_unit_dip, 16, getresources()                 .getdisplaymetrics());         v.setpadding(padding, padding, padding, padding);         v.setgravity(gravity.center);         container.addview(v, 0);         return v;      }       @override     public void destroyitem(viewgroup container, int position, object view) {         container.removeview((view) view);     }      @override     public boolean isviewfromobject(view v, object o) {         return v == ((view) o);     }  } } 

where need set text , page changes, more try , more fraustrated, guys throw here please? way

inside oncreateview of dialogfragment should do:

view v = inflater.inflate(r.layout.hello_world, container, false); view tv = v.findviewbyid(r.id.text); ((textview)tv).settext("this instance of mydialogfragment"); 

check dialogfragment reference
