我有一个使用标记在Google地图中标记的地点的列表。我想选择一个标记,以使其以不同的颜色突出显示。当我单击同一标记或任何其他标记时,我要删除在第一个标记中所做的选择,并将其设置回默认颜色。
这是我的onClusterItemClick方法
override fun onClusterItemClick(p0: Station?): Boolean {
dragView.visibility = View.VISIBLE
viewModel.loadStation(p0?.id!!)
val marker = renderer.getMarker(p0)
//save previous merker here
marker?.setIcon(BitmapDescriptorFactory.fromResource(R.drawable.ic_map_pin_selected))
return true
}
这是我的Station Renderer
/**
* Class to design the pin point into the map
*/
inner class StationRenderer(context: Context, map: GoogleMap,
clusterManager: ClusterManager<Station>) : DefaultClusterRenderer<Station>(context, map, clusterManager) {
override fun onBeforeClusterRendered(cluster: Cluster<Station>?, markerOptions: MarkerOptions?) {
markerOptions?.icon(BitmapDescriptorFactory.fromBitmap(createStoreMarker(cluster?.size.toString())))
}
override fun onBeforeClusterItemRendered(item: Station?, markerOptions: MarkerOptions?) {
markerOptions?.icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_map_pin))
}
private fun createStoreMarker(stationsCount:String): Bitmap {
val markerLayout = layoutInflater.inflate(R.layout.marker_item, null)
val markerImage = markerLayout.findViewById(R.id.marker_image) as ImageView
val markerRating = markerLayout.findViewById(R.id.marker_text) as TextView
markerImage.setImageResource(R.drawable.ic_map_pin)
markerRating.text = stationsCount
markerLayout.measure(View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED), View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED))
markerLayout.layout(0, 0, markerLayout.getMeasuredWidth(), markerLayout.getMeasuredHeight())
val bitmap = Bitmap.createBitmap(markerLayout.getMeasuredWidth(), markerLayout.getMeasuredHeight(), Bitmap.Config.ARGB_8888)
val canvas = Canvas(bitmap)
markerLayout.draw(canvas)
return bitmap
}
override fun shouldRenderAsCluster(cluster: Cluster<Station>?): Boolean {
return cluster?.size !!> 1
}
}

在googleMaps中,这些不是被选中或取消选中的东西,也不是专门用于but
的{{1}}监听器,您可以使用此监听器并添加一些逻辑来实现该目标。
onMarkerClick();
