Set Image from drawable as marker in Google Map version 2

Question

I am using this part of code to add a marker in a MapFragment in Google Map Version 2.

MarkerOptions op = new MarkerOptions();
op.position(point         


        

Answer 1

This is how you can set a Drawable as a Marker.

BitmapDescriptor icon = BitmapDescriptorFactory.fromResource(R.drawable.current_position_tennis_ball)

MarkerOptions markerOptions = new MarkerOptions().position(latLng)
         .title("Current Location")
         .snippet("Thinking of finding some thing...")
         .icon(icon);

mMarker = googleMap.addMarker(markerOptions);

VectorDrawables and XML based Drawables do not work with this.

@Lukas Novak answer is not showing anything because you also have to set the bounds on Drawable.
This works for any drawable. Here is a fully working example:

public void drawMarker() {
    Drawable circleDrawable = getResources().getDrawable(R.drawable.circle_shape);
    BitmapDescriptor markerIcon = getMarkerIconFromDrawable(circleDrawable);

    googleMap.addMarker(new MarkerOptions()
            .position(new LatLng(41.906991, 12.453360))
            .title("My Marker")
            .icon(markerIcon)
    );
}

private BitmapDescriptor getMarkerIconFromDrawable(Drawable drawable) {
    Canvas canvas = new Canvas();
    Bitmap bitmap = Bitmap.createBitmap(drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
    canvas.setBitmap(bitmap);
    drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());
    drawable.draw(canvas);
    return BitmapDescriptorFactory.fromBitmap(bitmap);
}

circle_shape.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval">
    <size android:width="20dp" android:height="20dp"/>
    <solid android:color="#ff00ff"/>
</shape>

If you have Drawable created programatically (so you have no resource for it), you can use this:

Drawable d = ... // programatically create drawable
Canvas canvas = new Canvas();
Bitmap bitmap = Bitmap.createBitmap(d.getIntrinsicWidth(), d.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
canvas.setBitmap(bitmap);
d.draw(canvas);
BitmapDescriptor bd = BitmapDescriptorFactory.fromBitmap(bitmap);

Then you have BitmapDescriptor, which you can pass into MarkerOptions.

Basically use bitmap insted of drawable. If you do have a drawable, convert it to bitmap.
Here is a code example in kotlin.

private fun placeNewMarker(whereToPlaceYourMarker: LatLng){

    val pickupMarkerDrawable = resources.getDrawable(R.drawable.your_marker_drawable,null)


    _pickupMarker =   mMap?.addMarker(MarkerOptions()
            .position(whereToPlaceYourMarker)
            .draggable(true)
            .title("My Marker")
            .icon(BitmapDescriptorFactory.fromBitmap(pickupMarkerDrawable.toBitmap(pickupMarkerDrawable.intrinsicWidth, pickupMarkerDrawable.intrinsicHeight, null))))
