如何使用地理编码latlng地址android获取地点ID

Question

我正在使用 MapclickListener onclick of map getting latlng 我正在对它们进行地理编码 我想要来自该地理编码地址的地点 ID 和使用该地址的地点详细信息。

mMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() {
   @Override
        public void onMapClick(LatLng latLng) {
            mMap.clear();
            mMap.addMarker(new MarkerOptions()
            .position(latLng));
            Geocoder geocoder = new Geocoder(context, Locale.ENGLISH);
            try {
              List<Address> addressList = geocoder.getFromLocation(latLng.latitude,latLng.longitude,1);

             // Get geocode address 
             // ***https://maps.googleapis.com/maps/api/geocode/json?address=Address&key=GOOGLE_KEY***
             // Get place_id using this address
             // Get place details using the place_id

            } catch (IOException e) {
                e.printStackTrace();
            }
            mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(latLng, DEFAULT_ZOOM));
        }
    });

Answer 1

您必须进行两次 API 调用

首先是 -

https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.8670522,151.1957362&radius=500&types=food&name=cruise&key=YOUR_API_KEY

在这里你会得到 JSON：

{
  "html_attributions" : [],
  "results" : [
    {
      "geometry" : {
        "location" : {
          "lat" : -33.870775,
          "lng" : 151.199025
        }
      },
      ...
      "place_id" : "ChIJrTLr-GyuEmsRBfy61i59si0",
      ...
    }
  ],
  "status" : "OK"
}

获得 json 后，下一步就是调用 -

https://maps.googleapis.com/maps/api/geocode/json?place_id=ChIJrTLr-GyuEmsRBfy61i59si0&key=YOUR_API_KEY

你会得到这样的 json：

{
   "html_attributions" : [],
   "result" : {
      "address_components" : [
         {
            "long_name" : "5",

但是：您也可以使用 google geocode lib，您应该在其中添加大量代码和 google 客户端初始化。
