How do I change the icons for the cluster objects in java google maps

Question

I'm stuck with a little problem in the Clustering library for google maps in Android studio. The problem is that I only have the default icons for the cluster objects, like these icons.

I would like to give the markers a custom icon, but I cant find anything about it on internet. And I find it too unclear on the library page.

Thanks in advance!

I found a solution! Here it is:

@Override
protected void onBeforeClusterRendered(Cluster<MyItem> cluster, MarkerOptions markerOptions)
{

    final Drawable clusterIcon = ContextCompat.getDrawable(MainActivity.context,R.drawable.[your_icon]);

    mClusterIconGenerator.setBackground(clusterIcon);

    //modify padding for one or two digit numbers
    if (cluster.getSize() < 10) {
        mClusterIconGenerator.setContentPadding(40, 20, 0, 0);
    }
    else 
    {
        mClusterIconGenerator.setContentPadding(30, 20, 0, 0);
    }

    Bitmap icon = mClusterIconGenerator.makeIcon(String.valueOf(cluster.getSize()));
    markerOptions.icon(BitmapDescriptorFactory.fromBitmap(icon));

}

This worked for me.
