Answer 1

Try this,

  BitmapDescriptor icon = BitmapDescriptorFactory.fromResource(R.drawable.location);
            LatLng bangalore = new LatLng(12.9716, 77.5946);

 MarkerOptions markerOptions = new MarkerOptions().position(bangalore)
          .title("Current Location")
            .snippet("hello").icon(icon);


 mMap.addMarker(markerOptions);

Answer 2

It's very simple :

new MarkerOptions().icon(BitmapDescriptorFactory.fromResource(R.drawable.icon))

In case you want the icon from a bitmap

new MarkerOptions().icon(BitmapDescriptorFactory.fromBitmap(bitmap));

Answer 3

// latitude and longitude
double latitude = 17.385044;
double longitude = 78.486671;

// create marker
MarkerOptions marker = new MarkerOptions().position(new LatLng(latitude, longitude)).title("Hello Maps");

// Changing marker icon
marker.setIcon(BitmapDescriptorFactory.fromResource(R.drawable.my_marker_icon)));

// adding marker
googleMap.addMarker(marker);

Use .icon() Add like this

Marker marker = map.addMarker(new MarkerOptions().position(currentLocation)
.icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_place_holder)));

Please note don't use vector Images, if you want to use vector use below code

private BitmapDescriptor bitmapDescriptorFromVector(Context context, @DrawableRes  int vectorDrawableResourceId) {
    Drawable background = ContextCompat.getDrawable(context, R.drawable.ic_map_pin_filled_blue_48dp);
    background.setBounds(0, 0, background.getIntrinsicWidth(), background.getIntrinsicHeight());
    Drawable vectorDrawable = ContextCompat.getDrawable(context, vectorDrawableResourceId);
    vectorDrawable.setBounds(40, 20, vectorDrawable.getIntrinsicWidth() + 40, vectorDrawable.getIntrinsicHeight() + 20);
    Bitmap bitmap = Bitmap.createBitmap(background.getIntrinsicWidth(), background.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(bitmap);
    background.draw(canvas);
    vectorDrawable.draw(canvas);
    return BitmapDescriptorFactory.fromBitmap(bitmap);
}

Answer 5

In the newer versions of GoogleMaps for Android you can't call .setIcon() on a MarkerOptions object. Instead you have to add the marker options to the map which will give you a Marker on which you can then change the icon.

In Kotlin the code would look like this:

val markerOptions = MarkerOptions()
markerOptions.position(LatLng(40.419900, -111.880767))
val marker: Marker?  = googleMap?.addMarker(markerOptions)
val bitmapDescriptor = BitmapDescriptorFactory.fromResource(R.drawable.marker_customer_symbol)
marker?.setIcon(bitmapDescriptor)

For Xamarin C# users:

tappedMarker.Remove();
MarkerOptions markerOptions = new MarkerOptions();
markerOptions.SetTitle(tappedMarker.Title);
markerOptions.SetPosition(tappedMarker.Position);

markerOptions.SetIcon(BitmapDescriptorFactory.DefaultMarker(BitmapDescriptorFactory.HueGreen));
tappedMarker = googleMap.AddMarker(markerOptions);
