android地图实用程序中的DefaultClusterRenderer在v12.1中被破坏了吗

Question

当试图覆盖DefaultClusterRenderer中的任何函数时，它将不会在v1.2.1中编译。在v1.0 中一切似乎都很好

在这里，我想为clustericon设置颜色，并覆盖DefaultClusterRendereronBeforeClusterItemRendered以根据值设置颜色。

以下代码在v1.2.1中失败，在v1.1.0 中完全可以

package no.rogo.emptyfuel.utilities.cluster
import android.content.Context
import android.graphics.Color
import android.util.Log
import com.bumptech.glide.load.resource.bitmap.BitmapDrawableEncoder
import com.google.android.gms.maps.GoogleMap
import com.google.android.gms.maps.model.BitmapDescriptorFactory
import com.google.android.gms.maps.model.Marker
import com.google.android.gms.maps.model.MarkerOptions
import com.google.maps.android.clustering.Cluster
import com.google.maps.android.clustering.ClusterManager
import com.google.maps.android.clustering.view.DefaultClusterRenderer
import com.google.maps.android.ui.IconGenerator
import no.rogo.emptyfuel.R

class CustomClusterRenderer(
context: Context,
map: GoogleMap,
clusterManager: ClusterManager<ClusterStation?>?
) : DefaultClusterRenderer<ClusterStation?>(context,map,clusterManager)
{
private val TAG by lazy { this::class.java.simpleName }
private val clusterIconGenerator = IconGenerator(context.applicationContext)
override fun onBeforeClusterItemRendered(
item: ClusterStation?,
markerOptions: MarkerOptions?
) {
var markerHue = when(item?.statusLevel)
{
StatusLevel.SINCE_NEW -> BitmapDescriptorFactory.HUE_GREEN
StatusLevel.SINCE_FAIR -> BitmapDescriptorFactory.HUE_YELLOW
StatusLevel.SINCE_OLD -> BitmapDescriptorFactory.HUE_RED
StatusLevel.SINCE_OLDER -> BitmapDescriptorFactory.HUE_BLUE
StatusLevel.NOT_SET -> BitmapDescriptorFactory.HUE_CYAN
StatusLevel.NOT_AVAILABLE -> BitmapDescriptorFactory.HUE_AZURE
StatusLevel.HIDDEN -> BitmapDescriptorFactory.HUE_ROSE
StatusLevel.UNCERTAIN -> BitmapDescriptorFactory.HUE_ORANGE
StatusLevel.UNKNOWN -> BitmapDescriptorFactory.HUE_MAGENTA
else -> BitmapDescriptorFactory.HUE_VIOLET
}

//Color.colorToHSV(markerColor,markerHue)
//Log.i(TAG,"map3: markerHue = ${markerHue[0]}")
val markerDescriptor = BitmapDescriptorFactory.defaultMarker(markerHue)
markerOptions?.icon(markerDescriptor)
super.onBeforeClusterItemRendered(item, markerOptions)
}
override fun onClusterItemRendered(clusterItem: ClusterStation?, marker: Marker?) {
super.onClusterItemRendered(clusterItem, marker)
}
override fun onBeforeClusterRendered(
cluster: Cluster<ClusterStation?>?,
markerOptions: MarkerOptions?
) {
super.onBeforeClusterRendered(cluster, markerOptions)
}

}

有人知道发生了什么变化，以及如何修复吗？

我找到了问题的解决方案(https://github.com/googlemaps/android-maps-utils/pull/687)他们将参数更改为nulsafe，因此在更改时：

override fun onBeforeClusterItemRendered(
item: ClusterStation?,
markerOptions: MarkerOptions?
)

至

override fun onBeforeClusterItemRendered(
item: ClusterStation, 
markerOptions: MarkerOptions
)

修正了。这实际上是一个kotlin问题。。。
