android-maps-utils 中的 DefaultClusterRenderer 在 v1.2.1 中是否損壞？

Question

當試圖覆蓋 DefaultClusterRenderer 中的任何函數時，它不會在 v1.2.1 中編譯。 v1.1.0 中一切正常

在這里，我想將 colors 設置為 clustericons，並覆蓋DefaultClusterRenderer onBeforeClusterItemRendered以根據值設置 colors。

以下代碼在 v1.2.1 中失敗，在 v1.1.0 中完全沒問題

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

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)
    }


}

有誰知道發生了什么變化，以及如何解決？

我找到了問題的解決方案，在這個拉（ https://github.com/googlemaps/android-maps-utils/pull/687 ）中，他們將參數更改為 nullsafe，所以在更改時：

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

至

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

解決它。 它實際上是一個 kotlin 問題......
