How can we achieve a map marker icon with vector asset file, the way google shows it like this, programatically:
Update:
m
Here is the code for kotlin lovers ;)
private fun bitMapFromVector(vectorResID:Int):BitmapDescriptor {
val vectorDrawable=ContextCompat.getDrawable(context!!,vectorResID)
vectorDrawable!!.setBounds(0,0,vectorDrawable!!.intrinsicWidth,vectorDrawable.intrinsicHeight)
val bitmap=Bitmap.createBitmap(vectorDrawable.intrinsicWidth,vectorDrawable.intrinsicHeight,Bitmap.Config.ARGB_8888)
val canvas=Canvas(bitmap)
vectorDrawable.draw(canvas)
return BitmapDescriptorFactory.fromBitmap(bitmap)
}
Try this
MarkerOptions op = new MarkerOptions();
op.position(src_latlng);
Marker origin_marker = googleMap.addMarker(op);
Bitmap bitmap = getBitmap(this,R.drawable.ic_map_marker);
origin_marker.setIcon(BitmapDescriptorFactory.fromBitmap(bitmap));
getBitmap
public Bitmap getBitmap(Context context, int drawableId) {
Drawable drawable = ContextCompat.getDrawable(context, drawableId);
if (drawable instanceof BitmapDrawable) {
return BitmapFactory.decodeResource(context.getResources(), drawableId);
} else if (drawable instanceof VectorDrawable) {
return getBitmap((VectorDrawable) drawable);
} else {
throw new IllegalArgumentException("unsupported drawable type");
}
}

For a Kotlin user.Please check below code.As I ddid in Fragment class.
class MapPinFragment : Fragment() {
private lateinit var googleMap1: GoogleMap
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
}
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?): View? {
return inflater.inflate(R.layout.fragment_map_pin, container, false)
}
override fun onActivityCreated(savedInstanceState: Bundle?) {
super.onActivityCreated(savedInstanceState)
mapView.onCreate(savedInstanceState)
mapView.onResume()
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
mapView.getMapAsync { googleMap ->
googleMap1 = googleMap as GoogleMap
addCustomMarker()
}
}
private fun addCustomMarker() {
Log.d("addCustomMarker", "addCustomMarker()")
if (googleMap1 == null) {
return
}
// adding a marker on map with image from drawable
googleMap1.addMarker(
MarkerOptions()
.position(LatLng(23.0225 , 72.5714))
.icon(BitmapDescriptorFactory.fromBitmap(getMarkerBitmapFromView()))
)
}
override fun onDestroy() {
super.onDestroy()
if (mapView != null)
mapView.onDestroy()
}
override fun onLowMemory() {
super.onLowMemory()
mapView.onLowMemory()
}
private fun getMarkerBitmapFromView(): Bitmap? {
val customMarkerView: View? = layoutInflater.inflate(R.layout.view_custom_marker, null)
// val markerImageView: ImageView =
// customMarkerView.findViewById<View>(R.id.profile_image) as ImageView
customMarkerView?.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED );
customMarkerView?.layout(0, 0, customMarkerView.measuredWidth, customMarkerView.measuredHeight);
customMarkerView?.buildDrawingCache();
val returnedBitmap = Bitmap.createBitmap(
customMarkerView!!.measuredWidth, customMarkerView.measuredHeight,
Bitmap.Config.ARGB_8888
)
val canvas = Canvas(returnedBitmap)
canvas.drawColor(Color.WHITE, PorterDuff.Mode.SRC_IN)
val drawable = customMarkerView.background
drawable?.draw(canvas);
customMarkerView.draw(canvas);
return returnedBitmap;
}
}
