The following code snippet which uses Google Places API for android worked for me
以下使用 Google Places API for android 的代码片段对我有用
Places.GeoDataApi.getPlaceById(mGoogleApiClient, placeId)
.setResultCallback(new ResultCallback<PlaceBuffer>() {
@Override
public void onResult(PlaceBuffer places) {
if (places.getStatus().isSuccess()) {
final Place myPlace = places.get(0);
LatLng queriedLocation = myPlace.getLatLng();
Log.v("Latitude is", "" + queriedLocation.latitude);
Log.v("Longitude is", "" + queriedLocation.longitude);
}
places.release();
}
});

Google Place Detailsis the answer.
Google 地方详情就是答案。
From the place_idyou got, query Place Details something like https://maps.googleapis.com/maps/api/place/details/json?placeid={placeid}&key={key}and you can get the latand lngfrom result.geometry.locationJSON.
从place_id你得到的，查询 Place Details 之类的https://maps.googleapis.com/maps/api/place/details/json?placeid={placeid}&key={key}，你可以从JSON 中获取lat和。lngresult.geometry.location

Each place returned in the place-autocomplete response has an Id and a reference string as explained here.
在这个地方，自动完成响应返回的每个地方都有一个ID和解释参考串这里。
Use either (preferably Id since reference is deprecated) to query Places API for the full information about that place (including lat/lng): https://developers.google.com/places/documentation/details#PlaceDetailsRequests
使用任一（最好是 Id，因为参考已弃用）查询 Places API 以获取有关该地点的完整信息（包括 lat/lng）：https: //developers.google.com/places/documentation/details#PlaceDetailsRequests
Regarding shyam's comment - Geocoding will work only if you got a full address in the autocomplete response which is not always the case. Also Geocoding gives a list of possible results since the place description you get in the autocomplete response is not unique. Depending on your needs, geocoding might be enough.
关于 shyam 的评论 - 只有在自动完成响应中获得完整地址时，地理编码才会起作用，但情况并非总是如此。此外，地理编码提供了可能结果的列表，因为您在自动完成响应中获得的地点描述不是唯一的。根据您的需要，地理编码可能就足够了。

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == Constant.REQUEST_LOCATION_CODE) {
Place place = PlaceAutocomplete.getPlace(this, data);
if (place != null) {
LatLng latLng = place.getLatLng();
mStringLatitude = String.valueOf(latLng.latitude);
mStringLongitude = String.valueOf(latLng.longitude);
EditTextAddress.setText(place.getAddress());
}
}
}
With the code above, you can get the LatLngas well as the String address. Use the LatLng wherever you want.
使用上面的代码，您可以获得LatLng以及字符串地址。随时随地使用 LatLng。

Based on the latest version of AutoComplete documentation
基于最新版本的 AutoComplete 文档
Option 1: Embed an AutocompleteSupportFragment
选项 1：嵌入 AutocompleteSupportFragment
AutocompleteSupportFragment autocompleteFragment = (AutocompleteSupportFragment)
getSupportFragmentManager().findFragmentById(R.id.autocomplete_fragment);
autocompleteFragment
.setPlaceFields(Arrays.asList(Place.Field.ID,
Place.Field.NAME,Place.Field.LAT_LNG,Place.Field.ADDRESS));
Option 2: Use an intent to launch the autocomplete activity
选项 2：使用意图启动自动完成活动
List<Place.Field> fields = Arrays.asList(Place.Field.ID, Place.Field.NAME,Place.Field.LAT_LNG,Place.Field.ADDRESS);
// Start the autocomplete intent.
Intent intent = new Autocomplete.IntentBuilder(
AutocompleteActivityMode.FULLSCREEN, fields)
.build(this);
startActivityForResult(intent, AUTOCOMPLETE_REQUEST_CODE);
whichever fields you are interested in, you have to mention as mentioned above.
无论您对哪个领域感兴趣，都必须如上所述提及。
You'll get result as below:
你会得到如下结果：
onPlaceSelected:
{
"a":"#90, 1st Floor, Balaji Complex, Kuvempu Main Road, Kempapura, Hebbal
Kempapura, Bengaluru, Karnataka 560024, India",
"b":[],
"c":"ChIJzxEsY4QXrjsRQiF5LWRnVoc",
"d":{"latitude":13.0498176,"longitude":77.600347},
"e":"CRAWLINK Networks Pvt. Ltd."
}
Note: The result displayed is by parsing the Place object to json
注：显示的结果是将Place对象解析为json

add these line under function
在函数下添加这些行
autocomplete.addListener('place_changed', function() {});
var place = autocomplete.getPlace();
autocomplete.setFields(['place_id', 'geometry', 'name', 'formatted_address']);
var lng = place.geometry.location.lng();
var lat = place.geometry.location.lat();
var latlng = {lat , lng};
console.log(latlng);

do provide Place.Field.LAT_LNG to get the latitude and longitude for the place.
请提供 Place.Field.LAT_LNG 以获取该地点的纬度和经度。
autocompleteFragment.setPlaceFields(Arrays.asList(Place.Field.ID,
Place.Field.NAME,Place.Field.LAT_LNG));
then get LatLng
然后得到 LatLng
LatLng destinationLatLng = place.getLatLng();
and can see through toast
并且可以看透吐司
destlat = destinationLatLng.latitude;
destLon = destinationLatLng.longitude;
Toast.makeText(getApplicationContext(), "" + destlat + ',' + destLon, Toast.LENGTH_LONG).show();

Geocoding is a very indirect solution, and like the second responder said, if you do "Apple Store" it may not return the full address. Instead:
地理编码是一种非常间接的解决方案，就像第二个响应者所说的那样，如果您执行“Apple Store”，它可能不会返回完整地址。反而：
Place_ID contains everything you need. I am assuming you know how to get the place_id from the Places API (they have a full example if not).
Place_ID 包含您需要的一切。我假设您知道如何从 Places API 获取 place_id（如果没有，他们有一个完整的示例）。
Then pull a second request for the place details (including latitude and longitude under the geometry section) using the place_id following this documentation: https://developers.google.com/places/documentation/details?utm_source=welovemapsdevelopers&utm_campaign=mdr-devdocs
然后使用以下文档的 place_id 拉取对地点详细信息（包括几何部分下的纬度和经度）的第二个请求：https: //developers.google.com/places/documentation/details?utm_source =welovemapsdevelopers&utm_campaign =mdr-devdocs

Ref :- https://developers.google.com/places/android/place-details#get-placeThe above link gives a place object which will have lat and long . The place object is deirved from placeid that one gets from place autocomplete.
参考：- https://developers.google.com/places/android/place-details#get-place上面的链接给出了一个地方对象，它将具有 lat 和 long 。地点对象源自人们从地点自动完成获得的地点 ID。
