try adding a create method like this
This code reads a List of POI which come from a database
public WhatAroundMeOverlay( WhatAroundMe whatAroundMe,Drawable
defaultMarker,List<POI> listPOI ) {
super(defaultMarker);
this.whatAroundMe = whatAroundMe;
this.listPOI = listPOI;
Iterator<POI> iterator = listPOI.iterator();
while(iterator.hasNext()) {
POI location = iterator.next();
latitudeDouble = Double.valueOf(location.latitude) * 1E6;
longitudedouble = Double.valueOf(location.longitude) * 1E6;
geoPoint = new
GeoPoint(latitudeDouble.intValue(),longitudedouble.intValue());
mItemList.add(new OverlayItem(geoPoint , location.line0,
location.category));
}
populate();
}
@Override
protected OverlayItem createItem(int i) {
return mItemList.get(i);
}
