Question

在我的应用程序中，我试图访问片段中的自定义适配器，但它不允许我访问自定义适配器的UI，以下是我的代码段代码，任何人都可以告诉我我正在犯的错误。

提前致谢

public class All_Products extends ListFragment {

private TextView txtsortby;

ListView list;
String[] itemname ={
        "$55.00",
        "$55.00",

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> {



        }


    }

如何访问Fragment中的Customadapter？
