How to get latitude and longitude values of location using it's name

Question

Can any one explain How to get latitude and longitude values of location using location name

"Geocoding" is the magic word. Should be plenty of resources out there to help you get started. — MH., Oct 21 '13 at 08:46

Use the following code to get lat long values from location name by using reverse geocoding getFromLocationName()

Geocoder coder;
double latitude = 0.0;
double longitude = 0.0;

    try {       List<Address> address = coder.getFromLocationName(localionNameString, 5);
                    // if address is found
                    if (address.size() > 0) {
                    Address location = address.get(0);
                    latitude = location.getLatitude();
                    longitude = location.getLongitude();
                        }

                    } catch (Exception e) {
                        e.printStackTrace();
                    }

Hope this works

Its called Geocoding.Assuming the addr is in strAddres, you can use the below logic to get the lat and lon.

Geocoder coder = new Geocoder(this);
List<Address> address;

try {
    address = coder.getFromLocationName(strAddress,5);
    if (address == null) {
        return null;
    }
    Address location = address.get(0);
    location.getLatitude();
    location.getLongitude();

    p1 = new GeoPoint((int) (location.getLatitude() * 1E6),
                      (int) (location.getLongitude() * 1E6));

     return p1;
}

May be my MapHelper helps you -

public class MapHelper {
public static void setAddress(String address, GoogleMap map){
    JSONObject jsonObject =   getLocationInfo(address);
    Double longitute =  getLong(jsonObject);
    Double latitude =  getLat(jsonObject);
    CameraUpdate center = CameraUpdateFactory.newLatLng(new LatLng(latitude, longitute));
    CameraUpdate zoom = CameraUpdateFactory.zoomTo(15);
    map.moveCamera(center);
    map.animateCamera(zoom);
    map.clear();
    map.addMarker(new MarkerOptions().position(new LatLng(latitude, longitute)).title(address));
}

public static JSONObject getLocationInfo(String address) {
    StringBuilder stringBuilder = new StringBuilder();
    try {
        address = address.replaceAll(" ", "%20");
        HttpPost httppost = new HttpPost("http://maps.google.com/maps/api/geocode/json?address=" + address + "&sensor=false");
        HttpClient client = new DefaultHttpClient();
        HttpResponse response;
        stringBuilder = new StringBuilder();
        response = client.execute(httppost);
        HttpEntity entity = response.getEntity();
        InputStream stream = entity.getContent();
        int b;
        while ((b = stream.read()) != -1) {
            stringBuilder.append((char) b);
        }
    } catch (ClientProtocolException e) {
    } catch (IOException e) {
    }

    JSONObject jsonObject = new JSONObject();
    try {
        jsonObject = new JSONObject(stringBuilder.toString());
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return jsonObject;
}

public static Double getLong(JSONObject jsonObject) {
    Double longitute = 0.0;
    try {
        longitute = ((JSONArray) jsonObject.get("results")).getJSONObject(0)
                .getJSONObject("geometry").getJSONObject("location")
                .getDouble("lng");
    } catch (JSONException e) {
    }
    return longitute;
}

public static Double getLat(JSONObject jsonObject) {
    Double latitude = 0.0;
    try {
        latitude = ((JSONArray) jsonObject.get("results")).getJSONObject(0)
                .getJSONObject("geometry").getJSONObject("location")
                .getDouble("lat");

    } catch (JSONException e) {
    }
    return latitude;
}
}

How use:

MapHelper.setAddress("New York", mapFragment.getMap())
