Given a latitude and longitude, Get the location name

问题

I am developing an application wherein I get the latitude, longitude in my android device and post them to a web server.

and in a web application I show the location details with the help of google maps.

Here I have huge collection of lat long values which i loop it in my jsp and create multiple markers with info windows.

Now the problem is that I need to show the location name of the particular latitude and longitude in the Info Window of google maps.

Can anyone help me with the google maps script or how can i get the location name from the lat long values in my android phone itself, so that I can post that to my web server.

Here i am given a single just pass the latitude and longitude in this function then you got all the information related to this latitude and longitude.

public void getAddress(double lat, double lng) {
    Geocoder geocoder = new Geocoder(HomeActivity.mContext, Locale.getDefault());
    try {
        List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);
        Address obj = addresses.get(0);
        String add = obj.getAddressLine(0);
        add = add + "\n" + obj.getCountryName();
        add = add + "\n" + obj.getCountryCode();
        add = add + "\n" + obj.getAdminArea();
        add = add + "\n" + obj.getPostalCode();
        add = add + "\n" + obj.getSubAdminArea();
        add = add + "\n" + obj.getLocality();
        add = add + "\n" + obj.getSubThoroughfare();

        Log.v("IGA", "Address" + add);
        // Toast.makeText(this, "Address=>" + add,
        // Toast.LENGTH_SHORT).show();

        // TennisAppActivity.showDialog(add);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        Toast.makeText(this, e.getMessage(), Toast.LENGTH_SHORT).show();
    }
}

I hope you got you answer.

I have a very simple answer to my own question posted couple of months back.... Please check this... It worked for me..

Geocoder myLocation = new Geocoder(yourContext, Locale.getDefault());
List<Address> myList = myLocation.getFromLocation(Double.parseDouble(latitude),Double.parseDouble(longitude), 1);
Address address = (Address) myList.get(0);
String addressStr = "";
addressStr += address.getAddressLine(0) + ", ";
addressStr += address.getAddressLine(1) + ", ";
addressStr += address.getAddressLine(2);

Here is the code...

StringBuilder _homeAddress = null;
        try{
            _homeAddress = new StringBuilder();
            Address address = null;
            List<Address> addresses = _coder.getFromLocation(_lat,_lon,1);
            for(int index=0; index<addresses.size(); ++index)
            {
                address = addresses.get(index);
                _homeAddress.append("Name: " + address.getLocality() + "\n");
                _homeAddress.append("Sub-Admin Ares: " + address.getSubAdminArea() + "\n");
                _homeAddress.append("Admin Area: " + address.getAdminArea() + "\n");
                _homeAddress.append("Country: " + address.getCountryName() + "\n");
                _homeAddress.append("Country Code: " + address.getCountryCode() + "\n");
                _homeAddress.append("Latitude: " + address.getLatitude() + "\n");
                _homeAddress.append("Longitude: " + address.getLongitude() + "\n\n");
            }
        }
        catch(Exception e){

        }

Use android.location.geocoder.getFromLocation(double latitude, double longitude, int maxResults)

it will give you a list of addresses.

Its Working for me:

 public void getAddress(double lat, double lng) {
            Geocoder geocoder = new Geocoder(DistaceCalculating.this, Locale.getDefault());
            try {
                List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);
                Address obj = addresses.get(0);
                String   add = obj.getAddressLine(0);
                String  currentAddress = obj.getSubAdminArea() + ","
                        + obj.getAdminArea();
                double   latitude = obj.getLatitude();
                double longitude = obj.getLongitude();
                String currentCity= obj.getSubAdminArea();
                String currentState= obj.getAdminArea();
               add = add + "\n" + obj.getCountryName();
                add = add + "\n" + obj.getCountryCode();
                add = add + "\n" + obj.getAdminArea();
                add = add + "\n" + obj.getPostalCode();
                add = add + "\n" + obj.getSubAdminArea();
                add = add + "\n" + obj.getLocality();
                add = add + "\n" + obj.getSubThoroughfare();


                System.out.println("obj.getCountryName()"+obj.getCountryName());
                System.out.println("obj.getCountryCode()"+obj.getCountryCode());
                System.out.println("obj.getAdminArea()"+obj.getAdminArea());
                System.out.println("obj.getPostalCode()"+obj.getPostalCode());
                System.out.println("obj.getSubAdminArea()"+obj.getSubAdminArea());
                System.out.println("obj.getLocality()"+obj.getLocality());
                System.out.println("obj.getSubThoroughfare()"+obj.getSubThoroughfare());


                Log.v("IGA", "Address" + add);
                // Toast.makeText(this, "Address=>" + add,
                // Toast.LENGTH_SHORT).show();

                // TennisAppActivity.showDialog(add);
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
                Toast.makeText(this, e.getMessage(), Toast.LENGTH_SHORT).show();
            }
        }

Here you Go!

   private String getAddress() {
        GPSTracker   gps = new GPSTracker(ProductList.this);
        Geocoder geocoder = new Geocoder(ProductList.this, Locale.getDefault());
        String address="";
        try {
            List<Address> addresses = geocoder.getFromLocation(gps.getLatitude(), gps.getLongitude(), 1);
            Address obj = addresses.get(0);
            String  add = obj.getAddressLine(0);
//optional
          /*  add = add + "\n" + obj.getCountryName();
            add = add + "\n" + obj.getCountryCode();
            add = add + "\n" + obj.getAdminArea();
            add = add + "\n" + obj.getPostalCode();
            add = add + "\n" + obj.getSubAdminArea();
            add = add + "\n" + obj.getLocality();
            add = add + "\n" + obj.getSubThoroughfare();*/

            Log.e("Location", "Address" + add);
            address=add;

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            Toast.makeText(this, e.getMessage(), Toast.LENGTH_SHORT).show();
        }
        return address;
    }
