problems with map overlay items

I have quite some trouble to get the markers to show up for some
reasons.

This is what i have done:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

 
public void addOverlayBusinessItems()
 
    {
 
        Drawable defaultMarker = getResources().getDrawable
 
(R.drawable.pin);
 
        defaultMarker.setBounds(0, 0, defaultMarker.getIntrinsicWidth(),
 
defaultMarker.getIntrinsicHeight());
 
        myMapView.getOverlays().add(new MyItemizedOverlay
 
(defaultMarker));
 
        myMapView.postInvalidate();
 
    }
 
 class MyItemizedOverlay extends ItemizedOverlay<OverlayItem>
 
    {
 
        //create a list of overlay items from the JSON response we get
 
from Yelp
 
        private List<OverlayItem> mItemList = new ArrayList<OverlayItem>
 
()
 
        public MyItemizedOverlay(Drawable defaultMarker)
 
        {
 
                super(defaultMarker);
 
                GeoPoint gp = new GeoPoint(5309691, 8851933);
 
                mItemList.add(gp, "test", "first marker");
 
                populate();
 
        }
 
        @Override
 
        protected OverlayItem createItem(int index)
 
        {
 
                return mItemList.get(index);
 
        }
 
        @Override
 
        public int size()
 
        {
 
                return mItemList.size();
 
        }
 
    }
 
Parsed in 0.035 seconds,  using GeSHi 1.0.8.4

yet nothing shows up on the my mapview. Are there more that i need to
do?

you need to write draw function for that.

Did you already get it working?

If not, try replacing
' mItemList.add(gp, "test", "first marker") '
with
' mItemList.add(new OverlayItem(gp, "test", "first marker")) '
