在单个地理位置显示多个叠加层..？

Question

点击地图中的放置针时，我在叠加层中显示了一个图像。可能地，两个或更多个图像属于相同的纬度和经度。在这种情况下，我想显示属于那个特定纬度和经度的所有图像..！我怎样才能做到这一点。？

这就是我试过的......！

   for (int i = 0; i < AllData.neardeallist.size(); i++) {
        mapOverlays = mapview.getOverlays();

        drawable = this.getResources().getDrawable(R.drawable.pin);
        itemizedOverlay = new CustomItemizedOverlay<CustomOverlayItem>(
                drawable, mapview);

        point = new GeoPoint((int) (Double.parseDouble(AllData.neardeallist
                .get(i).getLatitude()) * 1E6),
                (int) (Double.parseDouble(AllData.neardeallist
                        .get(i).getLongitude()) * 1E6));
        CustomOverlayItem overlayItem = new CustomOverlayItem(point,
                StringEscapeUtils.unescapeXml(StringEscapeUtils
                        .unescapeHtml4(AllData.neardeallist.get(i)
                                .getDealTitle())),

                StringEscapeUtils.unescapeXml(StringEscapeUtils
                        .unescapeHtml4(AllData.neardeallist.get(i)
                                .getDescription()))
                        + ":"
                        + AllData.neardeallist.get(i).getDealId()
                        + ":" + AllData.neardeallist.get(i).getDealKey(),
                AllData.neardeallist.get(i).getDealImg());

        itemizedOverlay.addOverlay(overlayItem);
        mapOverlays.add(itemizedOverlay);

我的自定义叠加层..！
