String[] strings = getResources().getStringArray(R.array.spinner_options);
HintAdapter<String> hintAdapter = new HintAdapter<String>(this, android.R.layout.simple_spinner_item, strings);
hintAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
mSpinner.setAdapter(hintAdapter);
mSpinner.setSelection(hintAdapter.getCount());

        int count = super.getCount();
        // The last item will be the hint.
        return count > 0 ? count - 1 : count;
