title: Change Android Cluster attractiveness on google map api
body: <p>Can we <strong>change the attractiveness of a cluster</strong> so that more markers are attracted to it?</p>
  <p>My code : (A simple class extend that i use in my map fragment)</p>
  <pre><code>class MyClusterManagerRenderer(
     context : Context,
     map : GoogleMap,
     mClusterManager: ClusterManager&lt;ClusterItem&gt;
  ) : DefaultClusterRenderer&lt;ClusterItem&gt;(context, map, mClusterManager) {
  
     private val mContext = context
  
     override fun onBeforeClusterItemRendered(item: ClusterItem?, markerOptions: MarkerOptions?) {
        super.onBeforeClusterItemRendered(item, markerOptions)
  
        val iconFactory = IconGenerator(mContext)
        iconFactory.setColor(ContextCompat.getColor(mContext, R.color.color))
        iconFactory.setTextAppearance(R.style.googleMarkerText)
  
        markerOptions
           ?.icon(BitmapDescriptorFactory.fromBitmap(iconFactory.makeIcon(item!!.title)))
           ?.anchor(iconFactory.anchorU, iconFactory.anchorV)
     }
  
     override fun getColor(clusterSize: Int): Int { return ContextCompat.getColor(mContext, R.color.color) }
  
     override fun getMinClusterSize(): Int { return 3 }
  }
