如何使用地理编码 latlng 地址安卓获取地点 ID

Question

我正在使用MapclickListener点击地图获取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以及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"
}

在你得到你的json之后，你的下一步将是调用-

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",
"short_name" : "5",
"types" : [ "floor" ]

但是：你也可以使用谷歌地理编码库，你应该在其中添加大量代码和谷歌客户端初始化。
