推荐答案

您可以使用的谷歌的地理编码API 。你实际上寻找的是反向地理编码，但它支持这一点。你可以把它返回的XML，然后解析它的邮寄code（又名压缩code）。实际上应该是很简单的。

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.

要使用该API，只需访问HTTP通过使用正确的纬度和经度：

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

的https://maps.googleapis.com/maps/api/geo$c$c/xml?latlng=37.775,-122.4183333&sensor=true

然后使用XPath，或者你喜欢的XML解析器解析XML（或只是使用JSON）：

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

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);

我还没有实际测试过的code此位（和它显然需要异常处理），但我相信你就可以得到它从这里工作。

I haven't actually tested this bit of code (and it obviously needs exception handling), but I trust you'll be able to get it working from here.

至于获得位置本身，这previous问题概括起来很好：

As for getting the location itself, this previous question sums it up nicely:
