i'm using library in fragment, when run app swipemenulistview not showing contents, here on stack found guys using listview inside oncreateview method, tried didn't work

public class autorizadasfragment extends fragment {      private swipemenulistview listview;     private customarrayadapter adapter;     private list<string> data;      public autorizadasfragment() {     }      @override     public view oncreateview(layoutinflater inflater, viewgroup container,                              bundle savedinstancestate) {          view rootview = inflater.inflate(r.layout.fragment_autorizadas, container, false);           return rootview;     }       @override     public void onactivitycreated(bundle savedinstancestate) {         // todo auto-generated method stub         super.onactivitycreated(savedinstancestate);          data = new arraylist<string>();          data.add("teste 1");         data.add("teste 2");         data.add("teste 3");         data.add("teste 4");         data.add("teste 5");          listview = (swipemenulistview) getactivity().findviewbyid(r.id.list);          adapter = new customarrayadapter(getactivity(), data);         listview.setadapter(adapter);         swipemenucreator creator = new swipemenucreator() {              @override             public void create(swipemenu menu) {                 // create "open" item                 swipemenuitem openitem = new swipemenuitem(                         getactivity());                 // set item background                 openitem.setbackground(new colordrawable(color.rgb(0xc9, 0xc9,                         0xce)));                 // set item width                 openitem.setwidth(90);                 // set item title                 openitem.settitle("open");                 // set item title fontsize                 openitem.settitlesize(18);                 // set item title font color                 openitem.settitlecolor(color.black);                 // add menu                 menu.addmenuitem(openitem);                  // create "delete" item                 swipemenuitem deleteitem = new swipemenuitem(                         getactivity());                 // set item background                 deleteitem.setbackground(new colordrawable(color.rgb(0xf9,                         0x3f, 0x25)));                 // set item width                 deleteitem.setwidth(90);                 // set icon                 deleteitem.seticon(r.drawable.ic_exit);                 // add menu                 menu.addmenuitem(deleteitem);             }         };          listview.setmenucreator(creator);     }       @override     public void oncreateoptionsmenu(menu menu, menuinflater inflater) {         // todo auto-generated method stub         super.oncreateoptionsmenu(menu, inflater);         inflater.inflate(r.menu.menu_main, menu);       } } 

xml:

 <linearlayout         style="@style/formregister"         android:orientation="vertical"         android:weightsum="1"         android:layout_width="fill_parent"         android:layout_height="fill_parent">          <com.baoyz.swipemenulistview.swipemenulistview             android:id="@+id/list"             android:layout_width="fill_parent"             android:layout_height="match_parent"             android:scrollbars="vertical"/> </linearlayout> 

you can hold reference root view adding private attribute e.g.

private view rootview = null; 

and change following line in oncreateview:

view rootview = inflater.inflate(r.layout.fragment_autorizadas, container, false); 

to

rootview = inflater.inflate(r.layout.fragment_autorizadas, container, false); 

then not need use "getactivity().findviewbyid(r.id.list);" (it become "rootview.findviewbyid(r.id.list);")

i proposing because not sure view created in oncreateview added activities root view when onactivitycreated() called.
