How to get street name from coordinates?

问题

I have the longitude and latitude into two separate EditText I want that when I press a button the street name appears in another EditText.

I tried with the Public Address getAddressForLocation method, but I have not gotten it to work..

Code

public Address getAddressForLocation(Context context, Location location) throws IOException {

        if (location == null) {
            return null;
        }
        double latitude = location.getLatitude();
        double longitude = location.getLongitude();
        int maxResults = 1;

        Geocoder gc = new Geocoder(context, Locale.getDefault());
        List<Address> addresses = gc.getFromLocation(latitude, longitude, maxResults);

        for (int i = 0; i < addresses.getMaxAddressLineIndex(); i++) {
            Log.d("=Adress=",addresses.getAddressLine(i));
        }
    }

How to get Street name from coordinates?

UPDATE (SOLUTION)

Geocoder geocoder = new Geocoder(this, Locale.getDefault());

            try {
                List<Address> addresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1);

                if (addresses != null) {
                    Address returnedAddress = addresses.get(0);
                    StringBuilder strReturnedAddress = new StringBuilder();
                    for (int i = 0; i < returnedAddress.getMaxAddressLineIndex(); i++) {
                        strReturnedAddress.append(returnedAddress.getAddressLine(i)).append("");
                    }
                    et_lugar.setText(strReturnedAddress.toString());
                }
                else {
                    et_lugar.setText("No Address returned!");
                }
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
                et_lugar.setText("Canont get Address!");
            }

Thanks

The docs mention the getThoroughfare() method, which may be null. I'd try that first. If null, then I'd try to get something useful from getAddressLine(). It's possible you cannot get a street name for all cases.

first of all, does your phone support location? you need to post the error as well so we know whats the real problem

assuming your phone supports locations, try using the getAdressLine() :

    List<Address> addresses = gc.getFromLocation(latitude, longitude, 1);
    Log.d("=Adress=",addresses.get(0).getAddressLine(0));

the catch here is getting what you want from the list that has the address class structure
