Android Question Google_Maps Marker Rotate

[prajinpraveen]

Hello, i am trying to create a marker with custom image and would like the image to rotate according to the direction/bearing of the street (eg Uber). please guide

this code snipplet rotates a marker. How you will get the bearing of the street? will you use OSM for that?

    Dim GoogleMapsExtras1 As GoogleMapsExtras
    Dim AndroidResources1 As AndroidResources
    Dim BitmapDescriptor1 As BitmapDescriptor
    Dim BitmapDescriptorFactory1 As BitmapDescriptorFactory
    Dim Icon As Bitmap
    Dim Mydrawable1 As BitmapDrawable
    Dim Markeropts As MarkerOptions

    Markeropts.Initialize
    Markeropts.Position2(48,9).Snippet("").Title("").Visible(True)
    Mydrawable1=AndroidResources1.GetApplicationDrawable("icon1")
    Icon=Mydrawable1.Bitmap
    BitmapDescriptor1=BitmapDescriptorFactory1.FromBitmap(Icon)
    Markeropts.Icon(BitmapDescriptor1)
    Markeropts.Rotate(45)  'Rotate the marker
    Dim Marker1 As Marker=GoogleMapsExtras1.AddMarker(gmap, Markeropts)

Thank you for the reply. Would it be possible to get the angle/bearing of the street so that we can rotate the marker accordingly. So everytime the street's direction changes, marker is rotated . Not sure if I am making my question clear. See screenshot in the first post

1) if you have 2 adresses in the street e.g. Chambers Street no 6 / Chambers Street no 8 you can geocode the adresses (with googlegeocode api) and then calculate the bearing of the 2 points...
2) you have the vector data of the streets (OpenStreetMap), then you can calculate the bearing from the vector data

Thank you, I will try your suggestions

used location class, and worked like a charm


Dim LocationFrom As Location
Dim LocationTo as Location

LocationTo.Initialize2(routeto.Latitude,routeto.Longitude)
LocationFrom.Initialize2(routebegin.Latitude,routebegin.Longitude)
rotateangle =LocationFrom.BearingTo(LocationTo)
