pulltorefreshlistview wrapper around listview, not extend listview, can't cast directly. can cast return value of findviewbyid pulltorefreshlistview , call getrefreshableview() retrieve underlaying listview. line
lstcategorylist = (listview)view.findviewbyid(r.id.lstcategory);
should
lstcategorylist = ((pulltorefreshlistview)view.findviewbyid(r.id.lstcategory)).getrefreshableview();
android has own swipetorefreshlayout widget. sure want still use pulltorefreshlistview?
