Custom marker in google maps in android with vector asset icon

Android Google Maps-Markers Google Maps-Android-Api-2

Android Problem Overview

How can we achieve a map marker icon with vector asset file, the way google shows it like this, programatically:

Update:

map.addMarker(new MarkerOptions()
    .position(latLng)
    .icon(BitmapDescriptorFactory.fromResource(R.drawable.your_vector_asset))
    .title(title);

this doesnot work when dealing with vector assets. The main reason to ask the question. The error with the above code:

> java.lang.IllegalArgumentException: Failed to decode image. The provided image must be a Bitmap.

You can use this method:

private BitmapDescriptor bitmapDescriptorFromVector(Context context, int vectorResId) {
        Drawable vectorDrawable = ContextCompat.getDrawable(context, vectorResId);
        vectorDrawable.setBounds(0, 0, vectorDrawable.getIntrinsicWidth(), vectorDrawable.getIntrinsicHeight());
        Bitmap bitmap = Bitmap.createBitmap(vectorDrawable.getIntrinsicWidth(), vectorDrawable.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(bitmap);
        vectorDrawable.draw(canvas);
        return BitmapDescriptorFactory.fromBitmap(bitmap);
}

So your code will look like:

map.addMarker(new MarkerOptions()
                .position(latLng)
                .icon(bitmapDescriptorFromVector(getActivity(), R.drawable.your_vector_asset))
                .title(title);

Edit:
In Kotlin it may look like:

private fun bitmapDescriptorFromVector(context: Context, vectorResId: Int): BitmapDescriptor? {
        return ContextCompat.getDrawable(context, vectorResId)?.run {
            setBounds(0, 0, intrinsicWidth, intrinsicHeight)
            val bitmap = Bitmap.createBitmap(intrinsicWidth, intrinsicHeight, Bitmap.Config.ARGB_8888)
            draw(Canvas(bitmap))
            BitmapDescriptorFactory.fromBitmap(bitmap)
        }
    }

Solution 2 - Android

I was looking for exact same requirement, and seeing this question made me happy at first, but same as @Shuddh I wasn't happy with the given answers.

To make my story short, I am using following code for this requirement:

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);
}

and a usage example:

.icon(bitmapDescriptorFromVector(this, R.drawable.ic_car_white_24dp));

Note: you may wish to use different bounding for your vectors, my vectors were 24dp in size and I've used a 48dp png image(blue-part, which can be a vector too) as background.

UPDATE: Adding screenshot as it was requested.

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)
}

Might be a bit late to the game but this works great with Google Maps v2:

public static BitmapDescriptor getBitmapFromVector(@NonNull Context context,
                                                   @DrawableRes int vectorResourceId,
                                                   @ColorInt int tintColor) {

    Drawable vectorDrawable = ResourcesCompat.getDrawable(
            context.getResources(), vectorResourceId, null);
    if (vectorDrawable == null) {
        Log.e(TAG, "Requested vector resource was not found");
        return BitmapDescriptorFactory.defaultMarker();
    }
    Bitmap bitmap = Bitmap.createBitmap(vectorDrawable.getIntrinsicWidth(),
            vectorDrawable.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(bitmap);
    vectorDrawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
    DrawableCompat.setTint(vectorDrawable, tintColor);
    vectorDrawable.draw(canvas);
    return BitmapDescriptorFactory.fromBitmap(bitmap);
}

Initialized as:

locationMarkerIcon = LayoutUtils.getBitmapFromVector(ctx, R.drawable.ic_location_marker,
                ContextCompat.getColor(ctx, R.color.marker_color));

Usage:

googleMap.addMarker(MarkerOptions().icon(getMarkerIcon()).position(latLng));

Note: getMarkerIcon() just returns the initialized non null locationMarkerIcon member variable.

Solution 5 - Android

In Kotlin: I used the below code to show the SVG image on Marker. Here, I used no background color / SVG.

fun getBitmapDescriptorFromVector(context: Context, @DrawableRes vectorDrawableResourceId: Int): BitmapDescriptor? {

    val vectorDrawable = ContextCompat.getDrawable(context, vectorDrawableResourceId)
    val bitmap = Bitmap.createBitmap(vectorDrawable!!.intrinsicWidth, vectorDrawable.intrinsicHeight, Bitmap.Config.ARGB_8888)
    val canvas = Canvas(bitmap)
    vectorDrawable.setBounds(0, 0, canvas.width, canvas.height)
    vectorDrawable.draw(canvas)

    return BitmapDescriptorFactory.fromBitmap(bitmap)
}

Use like this way:

googleMap?.addMarker(MarkerOptions().position(LatLng(it.latitude!!, it.longitude!!))
            .title(it.airLineDetails))?.setIcon(
            getBitmapDescriptorFromVector(requireContext(), R.drawable.ic_flight_blue))

Solution 6 - Android

If someone who is looking for in kotlin here is the method for you :

  private fun  bitmapDescriptorFromVector(vectorResId:Int):BitmapDescriptor {
            var vectorDrawable = ContextCompat.getDrawable(requireContext(), vectorResId);
            vectorDrawable!!.setBounds(0, 0, vectorDrawable.getIntrinsicWidth(), vectorDrawable.getIntrinsicHeight());
            var bitmap = Bitmap.createBitmap(vectorDrawable.getIntrinsicWidth(), vectorDrawable.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
            var canvas =  Canvas(bitmap);
            vectorDrawable.draw(canvas);
            return BitmapDescriptorFactory.fromBitmap(bitmap);
}

above method will convert you vector icon to bitmapdescritor

map.addMarker(new MarkerOptions()
                .position(latLng)
                .icon(bitmapDescriptorFromVector(getActivity(), R.drawable.your_vector_asset))
                .title(title)

and this one for setting marker for your map thanks for Leo Droidcoder from his answer only i have converted it to kotlin

Solution 7 - Android

convert vector resource to bitmap object and use BitmapDescriptorFactory.fromBitmap(bitmap)

   Bitmap bitmap = getBitmapFromVectorDrawable(getContext(),R.drawable.ic_pin);
   BitmapDescriptor descriptor =BitmapDescriptorFactory.fromBitmap(bitmap);
   MarkerOptions markerOptions = new MarkerOptions();
   markerOptions.icon(descriptor);

Bitmap converter:

 public static Bitmap getBitmapFromVectorDrawable(Context context, int drawableId) {
        Drawable drawable =  AppCompatResources.getDrawable(context, drawableId)
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
            drawable = (DrawableCompat.wrap(drawable)).mutate();
        }

        Bitmap bitmap = Bitmap.createBitmap(drawable.getIntrinsicWidth(),
                drawable.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(bitmap);
        drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
        drawable.draw(canvas);

        return bitmap;
    }

Solution 8 - Android

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");
   }
}

ic_map_marker.xml

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;

    }
