findViewById not recognised in ListFragment [duplicate]

Answer 1

That method is not defined in the Fragment class which is where I assume you're calling it. You have to use it on the View that the Fragment is showing. This is the same view that you return in onCreateView() and you can retrieve it by getView(). Thus, TextView txtMyTextBox = (TextView)getView().findViewById(R.id.my_text_box) should work.

Answer 2

When you use fragments, you should override the onCreateView method.

Here is an exemple :

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
    {
        View v = inflater.inflate(R.layout.YOUR_FRAGMENT_LAYOUT, null);

        TextView txtMyTextBox = (TextView)v.findViewById(R.id.my_text_box)

        return v;
    }
