群集管理器，无法将自定义图标分配给标记选项

Question

我正在使用Google Maps Utils对标记进行分组。现在我想自定义群集图标，为此我正在使用此代码

class ClusteredMarkerRender(context: Context, map: GoogleMap, clusterManager: ClusterManager<ClusteredMarker>)
    : DefaultClusterRenderer<ClusteredMarker>(context, map, clusterManager) {
    override fun onBeforeClusterRendered(cluster: Cluster<ClusteredMarker>?, markerOptions: MarkerOptions?) {
        super.onBeforeClusterRendered(cluster, markerOptions)
        markerOptions!!.icon = BitmapDescriptorFactory.fromResource(R.id.cluster_icon)
    }
    override fun shouldRenderAsCluster(cluster: Cluster<ClusteredMarker>?): Boolean {
        return cluster!!.size > 1
    }
}

但在markerOptions!!.icon安卓工作室说val cannot be reassigned.如何将自定义图标分配给markerOptions实例？

Answer 1

正如asm0dey所说，分配图标的正确方法是

markerOptions!!.icon(BitmapDescriptorFactory.fromResource(R.id.cluster_icon))
