我们可以在同一个 Android 地图视图中拥有不同类型的标记吗？
看看这个屏幕截图
我想知道如何在同一个 Android 地图视图中添加不同类型的标记？因为我们必须使用 5nt 可绘制对象创建一个覆盖列表，并且以后无法更改此可绘制对象（标记）。
List<Overlay> mapOverlays = mapView.getOverlays();
Drawable drawable = Activity.this.getResources().getDrawable(R.drawable.icon);
MyItemizedOverlay itemizedOverlay = new MyItemizedOverlay(drawable ,Activity.this);
GeoPoint point = new GeoPoint( (int)(location.getLatitude()*1000000),
(int)(location.getLongitude()*1000000));
OverlayItem overlayitem = new OverlayItem(point, "Current Location :","+acTextView.getText());
itemizedOverlay.addOverlay(overlayitem);
mapOverlays.add(itemizedOverlay);
MapController mapController = mapView.getController();
mapController.animateTo(point);
mapController.setZoom(14);
Take a look at this screenshot
I wonder how can we add different kind of marker in the same Android mapview? Because we must create a list of overlays with fivent drawable, and cannot change this drawable (marker) later.
List<Overlay> mapOverlays = mapView.getOverlays();
Drawable drawable = Activity.this.getResources().getDrawable(R.drawable.icon);
MyItemizedOverlay itemizedOverlay = new MyItemizedOverlay(drawable ,Activity.this);
GeoPoint point = new GeoPoint( (int)(location.getLatitude()*1000000),
(int)(location.getLongitude()*1000000));
OverlayItem overlayitem = new OverlayItem(point, "Current Location :","+acTextView.getText());
itemizedOverlay.addOverlay(overlayitem);
mapOverlays.add(itemizedOverlay);
MapController mapController = mapView.getController();
mapController.animateTo(point);
mapController.setZoom(14);

至少您可以定义多个叠加层，每个叠加层都有自己的标记。不？
你也可以重写 ItemizedOveralay.draw
At least you can define more than one overlay, each one with its own marker. No?
And also you can override ItemizedOveralay.draw
