How to dynamically add polylines from an arraylist
问题 I have an places = ArrayList<ArrayList<LatLng>> I am adding LatLng points into the inner ArrayList and then I have a for loop that loops and adds polylines to the map.. except it doesnt do that... How can I add polylines dynamically to the GoogleMap? I checked whether or not places was being populated and it is. Thanks in advance. ArrayList<Polyline> pl = new ArrayList<Polyline>(); for(int i =0; i<places.size(); i++){ pl.add(mMap.addPolyline(new PolylineOptions().addAll(places.get(i)))); Log
