Get location name from fetched coordinates

问题

What i have: currently my app is only telling me the coordinates of my current location.

What i want: Get location name from coordinates fetched by gps, so that i could know where exactly i am. (Name of location)

回答1:

Here is complete code from fetching long - lat to getting address:

LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
String provider = locationManager.getBestProvider(new Criteria(), true);

Location locations = locationManager.getLastKnownLocation(provider);
List<String>  providerList = locationManager.getAllProviders();
if(null!=locations && null!=providerList && providerList.size()>0){                 
double longitude = locations.getLongitude();
double latitude = locations.getLatitude();
Geocoder geocoder = new Geocoder(getApplicationContext(), Locale.getDefault());                 
try {
    List<Address> listAddresses = geocoder.getFromLocation(latitude, longitude, 1);
    if(null!=listAddresses&&listAddresses.size()>0){
        String _Location = listAddresses.get(0).getAddressLine(0);
    }
} catch (IOException e) {
    e.printStackTrace();
}

}

You can us the GeoCoder which is available in android.location.Geocoder package. The JavaDocs gives u full explaination. The possible sample for u.

 List<Address> list = geoCoder.getFromLocation(location
                .getLatitude(), location.getLongitude(), 1);
        if (list != null & list.size() > 0) {
            Address address = list.get(0);
            result = address.getLocality();
            return result;

The result will return the name of the location.

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);
        GUIStatics.currentAddress = obj.getSubAdminArea() + ","
                + obj.getAdminArea();
        GUIStatics.latitude = obj.getLatitude();
        GUIStatics.longitude = obj.getLongitude();
        GUIStatics.currentCity= obj.getSubAdminArea();
        GUIStatics.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();

        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 get the solution to your answer.
