当用户点击图标时，如何获取ItemizedIconOverlay<OverlayItem> anotherItemizedIconOverlay的索引位置？例如，当用户点击/单击第一个图标时，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);

itemOverlay = new ItemizedOverlayWithFocus＆lt;＆gt;（new ArrayList（）， new ItemizedIconOverlay.OnItemGestureListener（）{ @覆盖 public boolean onItemSingleTapUp（final int index，final OverlayItem item）{ Toast.makeText（背景下，＆＃34;项目＆＃39;＆＃34; + item.getTitle（）+＆＃34;＆＃39; （index =＆＃34; + index +＆＃34;）单击“＃34;，Toast.LENGTH_LONG）。show（）; 返回true; }

                        @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);
