提前致谢

public class All_Products extends ListFragment {

private TextView txtsortby;

ListView list;
String[] itemname ={
        ".00",
        ".00",
        ".00",
        ".00"

};

Integer[] imgid={
        R.drawable.productfirst,
        R.drawable.productsecond,
        R.drawable.productfirst,
        R.drawable.productsecond

};

String[] itemprice={"BIG 50ml EDP","BIG 50ml EDP","BIG 50ml EDP","BIG 50ml EDP","BIG 50ml EDP","BIG 50ml EDP","BIG 50ml EDP","BIG 50ml EDP"};

public All_Products() {
}


@Override

                         Bundle savedInstanceState) {

    txtsortby=(TextView)rootView.findViewById(R.id.txt_sortby_allproducts);

    CustomListAdapter adapter=new CustomListAdapter(getActivity(), itemname, imgid,itemprice);

这样做：-

 public class All_Products extends ListFragment {
   //Watever variables u are using

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

       //vies defining here
        return rootView;
    }
       //CHANGE HERE

     class CustomListAdapter extends ArrayAdapter<String> {



        }


    }
