Disabling rows in ListPreference

Question

I am creating a settings menu for a free version of my app. I have a ListPreference displaying many different options. However, only some of these options are to be made available in the free version (I would like all options to be visible - but disabled, so the user knows what they are missing!).

I'm struggling to disable certain rows of my ListPreference. Does anybody know how this can be achieved?

Solved it.

I made a custom class extending ListPreference. I then used a custom ArrayAdapter and used methods areAllItemsEnabled() and isEnabled(int position).

public class CustomListPreference extends ListPreference {

    public CustomListPreference (Context context, AttributeSet attrs) {
        super(context, attrs);
    }


    protected void onPrepareDialogBuilder(Builder builder) {
        ListAdapter listAdapter = new CustomArrayAdapter(getContext(), R.layout.listitem, getEntries(), resourceIds, index);

        builder.setAdapter(listAdapter, this);
        super.onPrepareDialogBuilder(builder);
    }
}

and

public class CustomArrayAdapter extends ArrayAdapter<CharSequence> {

public CustomArrayAdapter(Context context, int textViewResourceId,
        CharSequence[] objects, int[] ids, int i) {
    super(context, textViewResourceId, objects);

}

   public boolean areAllItemsEnabled() {
        return false;
    }

    public boolean isEnabled(int position) {
        if(position >= 2)
            return false;
        else
            return true;
    }

public View getView(int position, View convertView, ViewGroup parent) {
             ...
    return row;
}
