android - 如何从android（kotlin）中的地点ID获取地点详细信息

问题描述

嗨，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) ->{ 错误说 Type mismatch Required: OnSuccessListener found : 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()
        })
    }

解决方案

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",
           "types" : [ "route" ]
        },
        {
           "long_name" : "Williamsburg",
           "short_name" : "Williamsburg",
           "types" : [ "neighborhood", "political" ]
        },
        {
           "long_name" : "Brooklyn",
           "short_name" : "Brooklyn",
           "types" : [ "political", "sublocality", "sublocality_level_1" ]
        },
        {
           "long_name" : "Kings County",
           "short_name" : "Kings County",
           "types" : [ "administrative_area_level_2", "political" ]
        },
        {
           "long_name" : "New York",
           "short_name" : "NY",
           "types" : [ "administrative_area_level_1", "political" ]
        },
        {
           "long_name" : "United States",
           "short_name" : "US",
           "types" : [ "country", "political" ]
        },
        {
           "long_name" : "11211",
           "short_name" : "11211",
           "types" : [ "postal_code" ]
        }
     ],
     "formatted_address" : "277 Bedford Ave, Brooklyn, NY 11211, USA",
     "geometry" : {
        "location" : {
           "lat" : 40.7142205,
           "lng" : -73.9612903
        },
        "location_type" : "ROOFTOP",
        "viewport" : {
           "northeast" : {
              "lat" : 40.71556948029149,
              "lng" : -73.95994131970849
           },
           "southwest" : {
              "lat" : 40.7128715197085,
              "lng" : -73.9626392802915
           }
        }
     },
     "place_id" : "ChIJd8BlQ2BZwokRAFUEcm_qrcA",
     "types" : [ "street_address" ]
  }
],
"status" : "OK"
}

从几何对象获取纬度并在谷歌地图上添加标记。
