HelloItemizedOverlay类扩展ItemizedOverlay {private ArrayList mOverlays = new ArrayList();private Context mContext;

    public HelloItemizedOverlay(Drawable defaultMarker, Context context) {
        super(boundCenterBottom(defaultMarker));
        mContext = context;
    }
    public void addOverlay(OverlayItem overlay) {
        mOverlays.add(overlay);
        populate();
    }
    @Override
    protected OverlayItem createItem(int i) {
        return mOverlays.get(i);
    }
    @Override
    public int size() {
        return mOverlays.size();
    }
    @Override
    protected boolean onTap(int index) {
        OverlayItem item = mOverlays.get(index);
        AlertDialog.Builder dialog = new AlertDialog.Builder(mContext);
        dialog.setTitle(item.getTitle());
        dialog.setMessage(item.getSnippet());
        dialog.show();
        return true;
    }
}

GeoPoint    geoPoint = new GeoPoint((int) (latitude * 1E6), (int) (longitude * 1E6));
        mapOverlays = mapView.getOverlays();
        Drawable drawable = this.getResources().getDrawable(R.drawable.pin);
        itemizedOverlay = new HelloItemizedOverlay(drawable, this);
overlayItem = new OverlayItem(geoPoint, "Starting Location", "any text");
                                    itemizedOverlay.addOverlay(overlayItem);
                        mapOverlays.add(itemizedOverlay);
            MapController mapController = mapView.getController();
            mapController.animateTo(geoPoint);

将代码内嵌。您将需要使用类似itemizeoverlay的东西。看
