如何从 android(kotlin) 中的地点 ID 获取地点详细信息

Question

您好，我想使用 placeID 获取地点详细信息，并使用 kotlin 在 android 地图活动中添加标记。我已经用 latlng 完成了，但没有用 placeID 。可以请任何帮助。 我的代码带有 latlng 。

override fun onMapReady(googleMap: GoogleMap) {
        mMap = googleMap

        val mdis= LatLng(1.301440, 103.847980)

        mMap.addMarker(MarkerOptions().position(mdis).title("MDIS").icon(BitmapDescriptorFactory.fromResource(R.drawable.icon)))
        mMap.moveCamera(CameraUpdateFactory.newLatLng(mdis))
        mMap.animateCamera(CameraUpdateFactory.zoomIn())
        mMap.animateCamera(CameraUpdateFactory.zoomTo(15F),2000,null)
        mMap.uiSettings.isZoomControlsEnabled=true
        if (ActivityCompat.checkSelfPermission(this,
                Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
            mMap.isMyLocationEnabled = true
        }
        else {//condition for Marshmello and above
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                requestPermissions(arrayOf(Manifest.permission.ACCESS_FINE_LOCATION), MY_PERMISSION_FINE_LOCATION)
            }
        }
        mMap.setOnMarkerClickListener(this)
    }

试过了，在 placesClient.fetchPlace(request).addOnSuccessListener(response) 处出现错误 ->{ 错误说需要类型不匹配：OnSuccessListener 找到：FetchplaceResponse

这是我更新的代码：

 override fun onMapReady(googleMap: GoogleMap) {
        mMap = googleMap

        var mdisplaceId = "ChIJRwCirzca2jERhd68E52R_2Q"
        //val placesClient = Places.createClient(this)

        var placeFields : List<Place.Field>
        placeFields = Arrays.asList(Place.Field.ID , Place.Field.NAME)

       var  request :  FetchPlaceRequest
        request = FetchPlaceRequest.newInstance(mdisplaceId, placeFields)

        lateinit var response : FetchPlaceResponse
        lateinit var placesClient : PlacesClient
            placesClient.fetchPlace(request).addOnSuccessListener(response) ->{  //error at this line near response 
            var place : Place
             place = response.getPlace()
        })
    }

使用地理编码 api，

https://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&key=YOUR_API_KEY

这将返回以下 json 响应，

{
"results" : [
  {
     "address_components" : [
        {
           "long_name" : "277",
           "short_name" : "277",
           "types" : [ "street_number" ]
        },
        {
           "long_name" : "Bedford Avenue",
           "short_name" : "Bedford Ave",

        {

     ],
     "formatted_address" : "277 Bedford Ave, Brooklyn, NY 11211, USA",
     "geometry" : {

从几何对象获取经纬度并在谷歌地图上添加标记。
