问题 I am using polygons on map and I want to have a text on them. Is there any possible way to do this? I tried to put simple text on map point but didn't make it. private void addPolygon(Region reg) { PolylineOptions polylineOptions = new PolylineOptions(); ArrayList<LatLng> coordList=reg.getAllPoints(); coordList.add(coordList.get(0)); int regColor = reg.getColor(); String regName = reg.getName(); //want to put a name on region polylineOptions.addAll(coordList); polylineOptions .width(5) .color

问题 I need to draw shapes just like those you would create with custom maps on Google Maps, using Android's MapView. In other words, if I draw a shape on the map, when I zoom out it should shrink, covering the same area of the map regardless of the zoom level. Example following the Android Reference: @Override public boolean draw(Canvas canvas, MapView mapView, boolean shadow, long when) { super.draw(canvas, mapView, shadow); //---translate the GeoPoint to screen pixels--- Point screenPts = new
