OSM中如何获取被点击的ItemizedIconOverlay的index

Question

如何在用户点击图标时获取 ItemizedIconOverlay<OverlayItem> anotherItemizedIconOverlay 的索引位置？例如，当用户 taps/clicks 第一个图标时，它应该得到整数 0

List<GeoPoint> nodes = nodeCoordinates();
ArrayList<OverlayItem> anotherOverlayItemArray = new ArrayList<>();
Drawable newMarker = getResources().getDrawable(R.drawable.marker_node);

for(int i = 0; i < nodes.size(); i++) {
    anotherOverlayItemArray.add(new OverlayItem("Road", "Nodes", nodes.get(i)));
    anotherOverlayItemArray.get(i).setMarker(newMarker);
}

ItemizedIconOverlay<OverlayItem> anotherItemizedIconOverlay
            = new ItemizedIconOverlay<>(
            this, anotherOverlayItemArray, null);
map.getOverlays().add(anotherItemizedIconOverlay);

这里有一个例子 https://github.com/osmdroid/osmdroid/blob/master/OpenStreetMapViewer/src/main/java/org/osmdroid/samplefragments/data/SampleMilitaryIconsItemizedIcons.java

确认，格式问题....

`

itemOverlay = new ItemizedOverlayWithFocus<>(new ArrayList(), 新 ItemizedIconOverlay.OnItemGestureListener() { @覆盖 public boolean onItemSingleTapUp(final int index, final OverlayItem item) { Toast.makeText( 语境， "Item '" + item.getTitle() + "' (index=" + index + ") 单次点击", Toast.LENGTH_LONG).show(); return 真； }

                        @Override
                        public boolean onItemLongPress(final int index, final OverlayItem item) {
                             Toast.makeText(
                                     context,
                                     "Item '" + item.getTitle() + "' (index=" + index
                                             + ") got long pressed", Toast.LENGTH_LONG).show();
                             return false;
                        }
                   }, context);
