navigation drawer with pinned (sticky) headers

Question

I have a program showing sticky headers in a ListView. I want to apply this to the navigation drawer. Below is the code for PinnedSectionListActivity.java. How to input this ListView in the Navigation Drawer menu?

import com.hb.examples.pinnedsection.R;

public class PinnedSectionListActivity extends ListActivity implements OnClickListener {

    static class SimpleAdapter extends ArrayAdapter<Item> implements com.hb.examples.PinnedSectionListView.PinnedSectionListAdapter {

        private static final int[] COLORS = new int[] {
            R.color.green_light, R.color.orange_light,
            R.color.blue_light, R.color.red_light };

        public SimpleAdapter(Context context, int resource, int textViewResourceId) {
            super(context, resource, textViewResourceId);
            generateDataset('A', 'Z', false);
        }

        public void generateDataset(char from, char to, boolean clear) {
         
         if (clear) clear();
         
            final int sectionsNumber = to - from + 1;
            prepareSections(sectionsNumber);

            int sectionPosition = 0, listPosition = 0;
            for (char i=0; i<sectionsNumber; i++) {
                Item section = new Item(Item.SECTION, String.valueOf((char)('A' + i)));
                section.sectionPosition = sectionPosition;
                section.listPosition = listPosition++;
                onSectionAdded(section, sectionPosition);
                add(section);

                final int itemsNumber = (int) Math.abs((Math.cos(2f*Math.PI/3f * sectionsNumber / (i+1f)) * 25f));
                for (int j=0;j<itemsNumber;j++) {
                    Item item = new Item(Item.ITEM, section.text.toUpperCase(Locale.ENGLISH) + " - " + j);
