How to split Geocoder response into pieces

Question

I want to do reverse geocoding. I have lat long and want API to return me the name of location.

For this I coded as below:

    Double l1 = 34.010920600000000000;
    Double l2 = 71.480397199999970000;
    BigDecimal lat =  new BigDecimal(l1, MathContext.DECIMAL64);;
    BigDecimal lng =  new BigDecimal(l2, MathContext.DECIMAL64);;

    LatLng location = new LatLng(lat, lng);

    //GeocoderRequest geocoderRequest = new GeocoderRequestBuilder().setAddress("Paris, France").setLanguage("en").getGeocoderRequest();
    GeocoderRequest geocoderRequest = new GeocoderRequestBuilder().setLocation(location).setLanguage("en").getGeocoderRequest();

    try {
        GeocodeResponse geocoderResponse = geocoder.geocode(geocoderRequest);
        System.out.println(geocoderResponse);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

Above code OK and but returns a detailed response as

   GeocodeResponse{status=OK, results=[GeocoderResult{types=[route], formattedAddress='Unnamed Road, University of Peshawar, Peshawar, Pakistan', addressComponents=[GeocoderAddressComponent{longName='Unnamed Road', shortName='Unnamed Road', types=[route]}, GeocoderAddressComponent{longName='University of Peshawar', shortName='University of

Instead of above long response, I only need short location name i.e. "University of Peshawar"

How would I do that?

Answer 1

There's a list of "results" contained in the response. You can get at them by

List<GeocoderResult> results = geocoderResponse.getResults();
for( GeocoderResult geores: results ){
    if( geores.getTypes().contains( "sublocality" ) ){
        System.out.println( "Address: " + geores.getFormattedAddress() );
    }
}

This prints

Address: University Campus, Peshawar, Pakistan
