Question

Android Google 地图集群图标在缩小时忽略自定义图标。有什么建议如何修复它吗？

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));
}

Answer 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)
}
