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

问题 I have been researching and trying to make sense. My question: are the encoded polylines that Google gives in its directions api same as the leg geometry encoded polylines of Open Trip Planner? 回答1: Late answer, but yes, Open Trip Planner returns google Encoded Polyline format.

问题 I have a sample google map here where I can draw a polyline and drag the marker to redraw the polyline. When I'm dragging the marker, I'm using Path.setMap(null) to redraw the Polyline as, google.maps.event.addListener(marker, 'dragend', function(event) { var newLatLng = event.latLng; var index = Latlngs.map(function(element) { return element[0]; }).indexOf(marker.id); if (index !== -1) { Latlngs[index] = [marker.id, newLatLng]; } console.log(Latlngs); var changedLine=[]; for (var i = 0; i <

问题 I am getting setOnPolylineClickListener by following method. mMap.setOnPolylineClickListener(new GoogleMap.OnPolylineClickListener() { @Override public void onPolylineClick(Polyline polyline) { } But this returns whole Polyline I want Latitude and Longitude of click position like we get by MapClickListener how to achieve this ? mMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() { @Override public void onMapClick(final LatLng point) { }); I have tried using PolyUtil with following

问题 I have a bounds to a place and created a polygon of that place. How can I generate a random point inside the bounds of that polygon? 回答1: One way of doing it. This will calculate the bounds of the polygon, then guess a random point inside that bounds, if the point is contained by the polygon, it will put a marker there. // calculate the bounds of the polygon var bounds = new google.maps.LatLngBounds(); for (var i=0; i < polygon.getPath().getLength(); i++) { bounds.extend(polygon.getPath()

问题 I am using SVG path notation to create markers along with a polyline using Google Maps API v3. Sometimes, after adding a few markers, they just stop showing from the map. If I pan the map, even just 1px, they show again. SVG markers stop showing after adding a few SVG markers show again after pan This happens in FF, Safari, Chrome and iPhone browsers. Here is my code for the polyline: var lineSymbol = { path: g.SymbolPath.FORWARD_OPEN_ARROW, scale:1.5 }; polyOptions = { strokeColor: '#0026b3'
