First of all your getView method doesn't implemented correctly see this

second, your TextView id that defiend in rowlist_layout.xml is textView1 not textView,correct that

third put breakpoint in your getView method and check if your arrays have values or not?

and if you still stuck, see this and do step by step

Try editing your onCreateView like this:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment

    View rootView = inflater.inflate(R.layout.fragment_display_lists, container, false);

    ListAdapter adapter = new ListAdapter(getActivity(),itemname, imgid);
    list = (ListView) rootView.findViewById (R.id.list);
    list.setAdapter(adapter);
    list.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                                int position, long id) {
            // TODO Auto-generated method stub
            String Slecteditem= itemname[position];
            Toast.makeText(getActivity().getApplicationContext(), Slecteditem, Toast.LENGTH_SHORT).show();

        }
    });
    return rootView;
}

and delete the Listview Stuff from your onCreate
