如何在android中使用openstreetmap获取纬度和经度的地址

Question

在我的应用程序中,我使用osm地图.我有经纬度.使用这种方法

proj = mapView.getProjection();
        loc = (GeoPoint) proj.fromPixels((int) e.getX(), (int) e.getY());
        String longitude = Double
                .toString(((double) loc.getLongitudeE6()) / 1000000);
        String latitude = Double
                .toString(((double) loc.getLatitudeE6()) / 1000000);
        Toast toast = Toast.makeText(getApplicationContext(), "Longitude: "
                + longitude + " Latitude: " + latitude, Toast.LENGTH_SHORT);
        toast.show();

所以从这里我将如何查询从osm数据库获取城市名称.请帮我.如何将其转换为人类可理解的形式.这是我正在使用的代码.链接

Answer 1

尝试使用此代码获取地址.

Geocoder geocoder;
List<Address> addresses;
geocoder = new Geocoder(this, Locale.getDefault());
addresses = geocoder.getFromLocation(latitude, longitude, 1);

String address = addresses.get(0).getAddressLine(0);
String city = addresses.get(0).getAddressLine(1);
String country = addresses.get(0).getAddressLine(2);

用于openstreammap

    final String requestString = "http://nominatim.openstreetmap.org/reverse?format=json&lat=" +
            Double.toString(lat) + "&lon=" + Double.toString(lon) + "&zoom=18&addressdetails=1";        

RequestBuilder builder = new RequestBuilder(RequestBuilder.GET, URL.encode(requestString));
try {
    @SuppressWarnings("unused")
    Request request = builder.sendRequest(null, new RequestCallback() {
        @Override
        public void onResponseReceived(Request request, Response response) {
            if (response.getStatusCode() == 200) {
                String city = "";
                try {
                    JSONValue json = JSONParser.parseStrict(response);
                    JSONObject address = json.isObject().get("address").isObject();
                    final String quotes = "^\"|\"$";

                    if (address.get("city") != null) {
                        city = address.get("city").toString().replaceAll(quotes, "");
                    } else if (address.get("village") != null) {
                        city = address.get("village").toString().replaceAll(quotes, "");
                    }
                } catch (Exception e) {
                }            
            }
        }
    });
} catch (Exception e) {
}
