get Lat Lang from a place_id returned by autocomplete place api

Question

I am searching the place in my apps using the google autocomplete place api and now I want to get latitude and longitude of the place that i have searched. How to get latitude a

Answer 1

Each place returned in the place-autocomplete response has an Id and a reference string as explained here.

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

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.

Answer 2

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:

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).

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

Answer 3

I got very simple solution to this problem thanks answer by Muhammad Yasir.

    List<Place.Field> placeFields = Arrays.asList(Place.Field.LAT_LNG, Place.Field.ADDRESS_COMPONENTS);
    autocompleteFragment.setPlaceFields(placeFields);

    autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
        @Override
        public void onPlaceSelected(Place place) {
            LatLng latLng = place.getLatLng(); // This will have required latitude and longitude
         }
   }

You can specify any field you want as in the list like name, address etc.

Note: This answer is for android java but I think there will be similar approach in other languages like javascript.

Answer 4

Places.GeoDataApi.getPlaceById(mGoogleApiClient, placeId)
  .setResultCallback(new ResultCallback < PlaceBuffer > () {
    @Override
    public void onResult(PlaceBuffer places) {
      if (places.getStatus().isSuccess() && places.getCount() > 0) {
        final Place myPlace = places.get(0);
        Log.i(TAG, "Place found: " + myPlace.getName());
        LatLng latlangObj = myPlace.getLatLng();
        Log.v("latitude:", "" + latlangObj.latitude);
        Log.v("longitude:", "" + latlangObj.longitude);
      } else {
        Log.e(TAG, "Place not found");
      }
      places.release();
    }
  });

Use this method for getting lat and lang from placeid.

Answer 5

The following code snippet which uses Google Places API for android worked for me

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();
  }
});

Answer 6

do provide Place.Field.LAT_LNG to get the latitude and longitude for the place.

 autocompleteFragment.setPlaceFields(Arrays.asList(Place.Field.ID, 
 Place.Field.NAME,Place.Field.LAT_LNG));

then get LatLng

LatLng destinationLatLng = place.getLatLng();

and can see through toast

 destlat = destinationLatLng.latitude;
 destLon = destinationLatLng.longitude;
 Toast.makeText(getApplicationContext(), "" + destlat + ',' + destLon, Toast.LENGTH_LONG).show();
