your tab should extend listfragment.
public class tab extends listfragment{ //your existing code... @override public void onactivitycreated(bundle savedinstancestate) { super.oncreate(savedinstancestate); new loadcomments().execute(); } @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { view v =inflater.inflate(r.layout.productlist,container,false); return v; } //your existing code... } i didn't test code should work.
