Geoprer.getFromLocationName(cityName,maxResults)

像这样使用它：

List<Address> addressList = geoCoder.getFromLocationName(cityName, 1);Address address = addressList.get(0);if(address.hasLatitude() && address.hasLongitude()){    double selectedLat = address.getLatitude();    double selectedLng = address.getLongitude();}
