Question

I want to do nothing more than change the font Typeface and size of my spinner text.

I have made some initial attempts. Nothing is crashing, but my spinner is blank. (I also have yet to implement the custom Typeface, I am just trying to get the spinner to work first.

In code:

protected SpinnerSortAdapter sAdapter;
    protected Spinner sort;
    protected String[] strings;

        sort = (Spinner) getActivity().findViewById(R.id.spinner2);
        strings = getActivity().getResources().getStringArray(R.array.sorting_items);
        SpinnerSortAdapter sAdapter = new SpinnerSortAdapter(getActivity(),
                android.R.layout.simple_spinner_item, strings);
        sAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        sort.setAdapter(sAdapter);
        sort.setOnItemSelectedListener(new MyOnItemSelectedListener());

Adapter:

public class SpinnerSortAdapter extends ArrayAdapter<String> {
public SpinnerSortAdapter(Context context, int textViewResourceId,
        String[] strings) {
    super(context, textViewResourceId, strings);
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View view = super.getView(position, convertView, parent);
    if (view instanceof TextView) {
        ((TextView) view).setTextSize(5);
    }
    return view;
}

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

}enter code here

You’re not initializing the adapter correctly. Your version of ArrayAdapter that takes two ints, one pointing to a layout file for the row and an int representing the id of a TextView widget from that layout file. This adapter will be empty. Your code should be like this:

String[] items = getResources().getStringArray(R.array.sorting_items);
SpinnerSortAdapter adapter = new SpinnerSortAdapter(getActivity(), android.R.layout.simple_spinner_item, items);

Also the adapter would be changed to:

 public class SpinnerSortAdapter extends ArrayAdapter<String> {

    public SpinnerSortAdapter(Context context, int textViewResourceId,
            String[] strings) {
        super(context, textViewResourceId, strings);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View view = super.getView(position, convertView, parent);
        if (view instanceof TextView) {
            ((TextView) view).setTextSize(5);
        }
        return view;
    }

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