【问题描述】：

android Google Map Cluster 图标在缩小时忽略自定义图标。有什么建议可以解决吗？

override fun onBeforeClusterRendered(cluster: Cluster<T>, markerOptions: MarkerOptions) 
    mClusterIconGenerator.setBackground(context?.let  ContextCompat.getDrawable(it, R.drawable.map_cluster_item) )
    mClusterIconGenerator.setTextAppearance(R.style.WhiteTextAppearance)
    val icon = mClusterIconGenerator.makeIcon(cluster.size.toString())
    markerOptions.icon(BitmapDescriptorFactory.fromBitmap(icon));

【参考方案1】：

修复了覆盖getDescriptorForCluster

private val mClusterIconGenerator = IconGenerator(context).apply 
    setBackground(context?.let  ContextCompat.getDrawable(it, R.drawable.map_cluster_item) )
    setTextAppearance(R.style.WhiteTextAppearance)

override fun onBeforeClusterRendered(cluster: Cluster<T>, markerOptions: MarkerOptions) 
    val icon = mClusterIconGenerator.makeIcon(cluster.size.toString())
    markerOptions.icon(BitmapDescriptorFactory.fromBitmap(icon));

override fun getDescriptorForCluster(cluster: Cluster<T>): BitmapDescriptor 
    val icon = mClusterIconGenerator.makeIcon(cluster.size.toString())
    return BitmapDescriptorFactory.fromBitmap(icon)
