NullPointerException when I set Visibility Gone

Question

I want to hide a TextView in a Fragment, but when I use textview.setVisibility(View.GONE);, I get NullPointerException, where is the problem? I have already initialized the textview, so I don't understand why I get this error.

This is a part of my code:

 @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.lista_activity, container, false);
        ListView scarsdaleweek;
        TextView spuntino;
        TextView merenda;
        TextView recordspuntino;
        TextView recordmerenda;
        Button btnscarsdale;
        scarsdaleweek = (ListView) rootView.findViewById(R.id.listaweek);
            d= new Database(getActivity());
            String scelta=d.checkScelta();
            final Cursor c = d.week(scelta);
            CursorLoader(c);
            if(scelta.equals("scarsdale")||scelta.equals("atkins")){



            String from[] = {
                    Codice.DATI_ID,
                    Codice.COLAZIONE,
                    Codice.PRANZO,
                    Codice.CENA,                
                    };

            int to[] = {
                    R.id.record_id,
                    R.id.record_colazione,
                    R.id.record_pranzo,
                    R.id.record_cena,
                    };
            @SuppressWarnings("deprecation")
            SimpleCursorAdapter sca = new SimpleCursorAdapter(rootView.getContext(),
                    R.layout.singolo_elemento_week,
                    c, from, to);
            scarsdaleweek = (ListView) rootView.findViewById(R.id.listaweek);
            scarsdaleweek.setAdapter(sca);
            spuntino =(TextView)rootView.findViewById(R.id.text_spuntino);
            merenda =(TextView)rootView.findViewById(R.id.text_merenda);
            recordspuntino =(TextView)rootView.findViewById(R.id.record_spuntino);
            recordmerenda =(TextView)rootView.findViewById(R.id.record_merenda);

            spuntino.setVisibility(View.GONE);
            merenda.setVisibility(View.GONE);
            recordspuntino.setVisibility(View.GONE);
            recordmerenda.setVisibility(View.GONE);
            }

EDIT-- I solved my problem, I was trying to access a textview in another view, I created an adapter and it works :)

public class CustomFontExampleAdapterLista extends SimpleCursorAdapter 
{

 Database d;
    @SuppressWarnings("deprecation")
    public CustomFontExampleAdapterLista(final Context context, final int layout, final Cursor c, final String[] from,
                final int[] to) {
            super(context, layout, c, from, to);

    }

    @Override
    public void bindView(final View view, final Context context, final Cursor cursor) {
        super.bindView(view, context, cursor);

        final TextView spuntino =(TextView)view.findViewById(R.id.text_spuntino);
        spuntino.setVisibility(View.GONE);  
        final TextView merenda =(TextView)view.findViewById(R.id.text_merenda);
        merenda.setVisibility(View.GONE);  

    }

}
