推荐答案

You can do it with Google's Geocoding API. What you're actually looking for is reverse-geocoding, but it supports that too. You can have it return XML and then parse it for the postal code (a.k.a zipcode). Should be quite simple actually.

To use the API, simply access it by HTTP with the correct latitude and longitude:

https://maps.googleapis.com/maps/api/geocode/xml?latlng=37.775,-122.4183333&sensor=true

Then parse the XML using XPath, or your favorite XML parser (or just use JSON):

XPath xpath = XPathFactory.newInstance().newXPath();
字符串表达式="//GeocodeResponse/result/address_component [type = \" postal_code \]/long_name/text()";
InputSource inputSource =新的InputSource("https://maps.googleapis.com/maps/api/geocode/xml?latlng=37.775,-122.4183333&sensor=true");
字符串邮政编码=(String)xpath.evaluate(expression，inputSource，XPathConstants.STRING);

XPath xpath = XPathFactory.newInstance().newXPath();
String expression = "//GeocodeResponse/result/address_component[type=\"postal_code\"]/long_name/text()";
InputSource inputSource = new InputSource("https://maps.googleapis.com/maps/api/geocode/xml?latlng=37.775,-122.4183333&sensor=true");
String zipcode = (String) xpath.evaluate(expression, inputSource, XPathConstants.STRING);
