Android Question Google maps animated marker

MoraviaVenus · Aug 19, 2017

Dear all,

in my app, which uses library GoogleMaps (2.00), I would like to use my custom marker, which is animated. Using custom marker can be done via command:

B4X:

...
gMap = MainMapFragment.GetMap
bmp.Initialize(File.DirAssets, "custom_marker.png")
Dim m3 As Marker = gMap.AddMarker3(48.207740, 16.366051, "Hofburg Palace", bmp)
...

..., but I want to make the marker alive, e.g. the marker will breathe (will grow and shrink). You can imagine it as an animated GIF.

Please, is it possible to have animated marker in Google map?

Thank you.

As far as i know you can not animate a marker.

Have a look there, maybe you can find some information - https://stackoverflow.com/questions...maps-v2-animate-marker-size?noredirect=1&lq=1.
It is Java, though.
Also on https://stackoverflow.com/questions/14864664/animating-markers-on-google-maps-v2 they are saying that marker has Marker.setIcon function added as of rev.7 of API v2. I don't think it its in B4A. Maybe this would work?

You can use gmap.AddMarker3 to use a specific Icon. But you can not change the Icon of this marker.

Did you have a look at the link I posted? https://stackoverflow.com/questions...maps-v2-animate-marker-size?noredirect=1&lq=1. I think that's what Java function Marker.setIcon does. Isn't it what they are doing with the animator function, if you look at the java code there?

You can use this code to change the marker icon:

B4X:

Sub MarkerSetIcon(marker As Marker, bmp As Bitmap)
   Dim jo As JavaObject = marker
   Dim bitmapdescriptor As JavaObject
   bitmapdescriptor.InitializeStatic("com.google.android.gms.maps.model.BitmapDescriptorFactory")
   jo.RunMethod("setIcon", Array(bitmapdescriptor.RunMethod("fromBitmap", Array(bmp))))
End Sub
