傳遞lon/lat和返回城市名稱的API

Question

我想在我的android應用程序中使用API​​（首選爲Google地圖，如果支持的話）以傳遞位置的經度/緯度並且API返回城市名稱。

在解決這個，你應該去getAddressLine（x）的

Answer 1

我相信API是速率的限制。即在一個小時內您不能多次訪問該API。Android包含一個Geocoder類，它也具有ReverseGeocoding功能。請看this link。

Answer 2

我相信谷歌並提供你在這裏 http://code.google.com/apis/maps/documentation/geocoding/#ReverseGeocoding

Answer 3

請求什麼Geonames.org是另一回事。下面是一個示例API調用來找到西雅圖附近的名字： http://api.geonames.org/citiesJSON?north=47.65&south=47.55&east=-122.30&west=-122.40&lang=de&username=demo
