用于传递 lon/lat 并返回城市名称的 API答案

【问题标题】：API to pass lon/lat and return city name用于传递 lon/lat 并返回城市名称的 API
【发布时间】：2011-07-17 00:57:33
【问题描述】：

我想在我的 android 应用程序中使用 API（如果支持的话，最好是谷歌地图）来传递位置的经度/纬度，并且 API 返回城市名称。

在解决这个问题时，您应该使用 getAddressLine(x)

【解决方案1】：

我认为 API 是有速率限制的。即你不能在一个小时内多次访问 API。Android 包含一个 Geocoder 类，它也执行 ReverseGeocoding。看看this link。

谢谢，我想这就是我需要的。我现在要测试一下。
我测试过，但是不能用它来获取城市。你知道怎么做吗？
你需要在manifest中拥有internet权限。 Geocoder geocoder = new Geocoder(this, Locale.getDefault()); List<Address> addresses = geocoder.getFromLocation(lat, lng, 1); addresses.get(0).getLocality(); Locality 应该给你城市。
感谢瓦伦！我已经拥有互联网许可。但它给了我空值。
可能纬度/经度无效。您可以在桌面浏览器的谷歌地图上输入纬度/经度，并确认有纬度/经度值的结果。

【解决方案2】：

我相信 google 确实提供了您在此处所要求的内容 http://code.google.com/apis/maps/documentation/geocoding/#ReverseGeocoding

Geonames.org 是另一个。这是一个用于查找西雅图附近名称的示例 API 调用： http://api.geonames.org/citiesJSON?north=47.65&south=47.55&east=-122.30&west=-122.40&lang=de&username=demo
