Here is the way, that how can you achieve it.

        LocationManager locationManager = (LocationManager) context
                    .getSystemService(Context.LOCATION_SERVICE);
        LocationListener locationListener = new LocationListener() {
            @Override
        public void onStatusChanged(String provider, int status,
                Bundle extras) {
        }

        @Override
        public void onProviderEnabled(String provider) {
        }

        @Override
        public void onProviderDisabled(String provider) {
        }

        @Override
        public void onLocationChanged(Location location) {
            Double l1 = location.getLatitude();
            Double l2 = location.getLongitude();
            address = GetAddress(l1, l2);               
        }
    };
    locationManager.requestLocationUpdates(
            LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);  

private String GetAddress(Double lat, Double lon) {
    Geocoder geocoder = new Geocoder(context, Locale.ENGLISH);
    String ret = "";
    List<Address> addresses = null;
    try {
        addresses = geocoder.getFromLocation(lat, lon, 1);
        if (!addresses.equals(null)) {
            Address returnedAddress = addresses.get(0);
            StringBuilder strReturnedAddress = new StringBuilder("\n");
            for (int i = 0; i < returnedAddress.getMaxAddressLineIndex(); i++) {
                strReturnedAddress
                        .append(returnedAddress.getAddressLine(i)).append(
                                "\n");
            }
            ret = "Around: " + strReturnedAddress.toString();
        } else {
            ret = "No Address returned!";
        }
    } catch (IOException e) {
        e.printStackTrace();
        ret = "Location: https://maps.google.co.in/maps?hl=en&q=" + lat
                + "," + lon;
    } catch (NullPointerException e) {
        e.printStackTrace();
        ret = lat + "," + lon;
    }
    return ret;
}

And also add these permissions in AndroidManifest:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

First get your current location Lattitude & Longitude, then get Lattitude & Longitude of each locations you have and find out distance of each place from your current location using distanceTo method of Location class and after that find out least distance from your list.
