polyline

Little background. I have a navigation setup for when you click on a certain navigation item, it creates markers on the map. If you click on a different navigation item, it removes the previous markers and sets up new ones. Well now I am working with polylines and trying to create the same concept here with the polylines , however I am having a difficult time. Here is what I have: // Global variable for array of lines var points= []; Setup my points. line1 = new google.maps.LatLng(line1Start, line1Finish); line2 = new google.maps.LatLng(line2Start, line2Finish); line3 = new google.maps.LatLng

I need to find nearest point from given CLLocationCoordinate2D on array of GMSPolyline . I can convert this to GMSPath if that's better. Is there any ready method (or any repository) for such calculations? I have some problems with implementation. I wonder how to create an algorithm: 1. for all polylines 1.1. find smallest distance between polyline and touch point, save CLLocationCoordinate2D 2. for all distances from point 1.1. 2.1. find the shortest one, it's CLLocationCoordinate2D is our point Now the question is how to achieve point 1.1..? Basing on SOF shortest distance question , I wrote

I am drawing a route between two points in a map. I receive the points this way: StringBuilder urlString = new StringBuilder(); urlString.append("http://maps.googleapis.com/maps/api/directions/json"); urlString.append("?origin=");// from urlString.append(Double.toString(src.latitude)); urlString.append(","); urlString.append(Double.toString(src.longitude)); urlString.append("&destination=");// to urlString.append(Double.toString(dest.latitude)); urlString.append(","); urlString.append(Double.toString(dest.longitude)); urlString.append("&sensor=false&mode="); if (tipo != null) { urlString

If there is a polyline on googlemap and a click is performed on the map, then how can I check whether that click was on polyline or somewhere else? Polyline line = googleMap.addPolyline(new PolylineOptions() .add(new LatLng(51.2, 0.1), new LatLng(51.7, 0.3)) .width(5) .color(Color.RED)); googleMap.setOnMapLongClickListener(new OnMapLongClickListener() { } }); Unfortunately there's no such thing as a polyline click listener so you'll have to listen to clicks on map and check if a click was registered on any of your polylines. You'll also have to save references to the polylines you added to
