Draw routes with directions (polylines with arrow icons)

[kingfisherphuoc]

Platform: Android
Mapbox SDK version: 4.1.0 final

Steps to trigger behavior

1. Get routes via routing api
2. Draw routes as:
   
   
PolylineOptions polylineOptions = new PolylineOptions()
.add(points)
.color(routeColor)
.alpha(0.8f)
.width(routeWidth);
mapboxMap.addPolyline(polylineOptions);


Expected feature

Is there any way to draw route (line) with direction in each line? As an arrow Icon?

You’d have to draw the arrow as a separate marker.

@kingfisherphuoc: at this time we are not thinking about exposing this as an API (@1ec5 please correct me if I'm wrong on this). Were you able to resolve this using markers as @1ec5 suggested?

Also, it’s worth noting that, once #837 lands in a future release, it’ll be possible to add the route line using GeoJSON; you’d add the arrows as a symbol layer with symbol-placement: line and icon-image.
