B4J Question Google Maps - Geodesic Polyline?

RichardN · Jan 17, 2018

In B4A you can describe a polyline object and draw a great-circle track instead of a rhumb line...

B4X:

'In B4A.....

Dim pl As Polyline = Gmap.AddPolyline
pl.Geodesic = True
pl.points = List.......

'However in B4J

gmap.AddPolyline(Waypoints,1,fx.Colors.blue)

I can't find any exposure of a Geodesic property in the B4J inplementation of Google Maps.

How is it done?

You can use this sub to set the geodesic property:

B4X:

Sub SetGeodesic(shape As JavaObject)
   shape.GetFieldJO("jsObject").RunMethod("eval", Array($"
       this.setOptions({
          geodesic: true
        });
   "$))
End Sub

B4X:

Dim p As MapPolygon = gmap.AddPolygon(points, 1, fx.Colors.Red, fx.Colors.Transparent, 0)
   SetGeodesic(p)
