如何从经纬度获取街道地址

Question

I am writing a program that gets the complete location from google maps, I managed to get latitude and longitude, but when it comes to address, I did everything as mentioned in different websites but I get an empty List.

Here is the code :

This is the function that saves the address in a list

public List<Address> getAddress() {
    try {
        Geocoder geocoder;
        List<Address> addresses;
        double latitude, longitude;
        latitude = Double.parseDouble(lat);
        longitude =  Double.parseDouble(lng);
        System.out.println(latitude + " / " + longitude);
        geocoder = new Geocoder(this);
        if (latitude != 0 || longitude != 0) {
            addresses = geocoder.getFromLocation(latitude ,
                    longitude, 2);
            return addresses;
        } else {
            Toast.makeText(this, "latitude and longitude are null",
                    Toast.LENGTH_LONG).show();
            return null;
        }
    } catch (Exception e) {
        e.printStackTrace();
        return null;
    }
}

And here is the function that calls it :

@Override
public void onLocationChanged(Location location) {

    lng = location.getLongitude() + "";
    lat = location.getLatitude() + "";

    try
    {
        getAddress();
    }
    catch (Exception e)
    {
        System.out.println("Can't Call getAddress()");
    }

    gotoLocation(location);

}

This is the given error each time the onLocationChanged() is called

Answer 1

Try this code

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

 addresses = geocoder.getFromLocation(latitude, longitude, 1); // Here 1     represent max location result to returned, by documents it recommended 1 to 5
 String address = addresses.get(0).getAddressLine(0); // If any additional address line present than only, check with max available address lines by getMaxAddressLineIndex()

String city = addresses.get(0).getLocality();
String state = addresses.get(0).getAdminArea();
String country = addresses.get(0).getCountryName();
String postalCode = addresses.get(0).getPostalCode();
String knownName = addresses.get(0).getFeatureName();

Answer 2

Here is the class which is working for me.

public class SubscriberDetails extends Activity implements GooglePlayServicesClient.ConnectionCallbacks,
GooglePlayServicesClient.OnConnectionFailedListener,OnEditorActionListener{

    private String finalAddress = "";

    //GPS 
    private boolean statusOfGPS = false;

    //GPS listener
    public static   Double _latitudeValue = null;
    public static   Double _longitudeValue = null;

    GPSTracker gps;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.subscriber_detail);


        gps = new GPSTracker(this);

        _latitudeValue = gps.getLatitude();
        _longitudeValue = gps.getLongitude();


        (new GetAddressTask(this)).execute();

    }



    /*
     * Following is a subclass of AsyncTask which has been used to get
     * address corresponding to the given latitude & longitude.
     */
    private class GetAddressTask extends AsyncTask<Location, Void, String>{
        Context mContext;
        public GetAddressTask(Context context) {
            super();
            mContext = context;
        }

        /*
         * When the task finishes, onPostExecute() displays the address. 
         */
        @Override
        protected void onPostExecute(String address) {

        }
        @Override
        protected String doInBackground(Location... params) {

            try {
                //current location
                Geocoder geoCoder = new Geocoder(SubscriberDetails.this, Locale.getDefault());
                StringBuilder builder = new StringBuilder();

                List<Address> address = geoCoder.getFromLocation(_latitudeValue,
                        _longitudeValue, 1);
                int maxLines = address.get(0).getMaxAddressLineIndex();
                for (int i=0; i<maxLines; i++) {
                    String addressStr = address.get(0).getAddressLine(i);
                    builder.append(addressStr);
                    builder.append(" ");
                }

                finalAddress = builder.toString(); //This is the complete address.
                System.out.println("Address = " +finalAddress);
            } catch (IOException e) {

            }
            catch (NullPointerException e) {

            }

            System.out.println("Current Locations = " + finalAddress);
            return finalAddress;


        }
    }// AsyncTask class



    @Override
    public void onConnectionFailed(ConnectionResult connectionResult) {
        // Display the error code on failure

        System.out.println("Connection Failure : " + connectionResult.getErrorCode());
    }

    @Override
    public void onConnected(Bundle arg0) {

        System.out.println("Connected");
    }

    @Override
    public void onDisconnected() {
        System.out.println("Disconnected. Please re-connect.");
    }

}

And GPSTracker Class:

public class GPSTracker extends Service implements LocationListener {

    private final Context mContext;

    // flag for GPS status
    boolean isGPSEnabled = false;

    // flag for network status
    boolean isNetworkEnabled = false;

    // flag for GPS status
    boolean canGetLocation = false;

    //flag for WIFi
    boolean isWifiEnabled = false;

    Location location; // location
    double latitude; // latitude
    double longitude; // longitude

    // The minimum distance to change Updates in meters
    private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 10; // 10 meters

    // The minimum time between updates in milliseconds
    private static final long MIN_TIME_BW_UPDATES = 1000 * 60 * 1; // 1 minute

    // Declaring a Location Manager
    protected LocationManager locationManager;

    public GPSTracker(Context context) {
        this.mContext = context;
        getLocation();
    }

    public Location getLocation() {
        try {
            locationManager = (LocationManager) mContext
                    .getSystemService(LOCATION_SERVICE);

            // getting GPS status
            isGPSEnabled = locationManager
                    .isProviderEnabled(LocationManager.GPS_PROVIDER);

            // getting network status
            isNetworkEnabled = locationManager
                    .isProviderEnabled(LocationManager.NETWORK_PROVIDER);

            isWifiEnabled = locationManager.isProviderEnabled(LocationManager.PASSIVE_PROVIDER);


            if (!isGPSEnabled && !isNetworkEnabled&&!isWifiEnabled) {
                // no network provider is enabled
            } else {
                this.canGetLocation = true;
                if (isNetworkEnabled) {
                    locationManager.requestLocationUpdates(
                            LocationManager.NETWORK_PROVIDER,
                            MIN_TIME_BW_UPDATES,
                            MIN_DISTANCE_CHANGE_FOR_UPDATES, this);

                    if (locationManager != null) {
                        location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
                        if (location != null) {
                            latitude = location.getLatitude();
                            longitude = location.getLongitude();
