回答1:

You can try using LatLngBounds and LatLngBounds.contains()

private LatLngBounds NewDelhi = new LatLngBounds(your special area SE LatLng , NE LatLng );

if(NewDelhi.contains(your location LatLng)) 
//Do something 

回答2:

Get city name from Location:

Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(myLocation.getLatitude(), myLocation.getLongitude(), 1);
String cityName = addresses.get(0).getAddressLine(0);
//String stateName = addresses.get(0).getAddressLine(1);
//String countryName = addresses.get(0).getAddressLine(2);
