中國國家氣象局提供了獲取所在城市天氣預報信息接口。通過這個接口，我們就可以獲取天氣信息了。
關於獲取天氣預報的實例參考android學習手冊，裏面有源碼。android學習手冊包含9個章節，108個例子，源碼文檔隨便看，例子都是可交互，可運行，源碼采用android studio目錄結構，高亮顯示代碼，文檔都采用文檔結構圖顯示，可以快速定位。360手機助手中下載,圖標上有貝殼
中國國家氣象局天氣預報接口總***提供了三個：
/data/sk/101010100.html
/data/cityinfo/101010100.html
/data/101010100.html
註：上面接口2014.3.4日已不再更新。換成這個：/atad/101230201.html。各位看34樓。在此感謝tdwll和黃曉佳cobish。
最詳細的信息來自第三個接口。上面url中的101010100是城市代碼，這裏是北京的城市代碼。只需要改變城市代碼，就可以得到所在城市的天氣信息。筆者在福州，所以選擇的城市代碼是福州101230101。
在瀏覽器上輸入url：/data/101230101.html得到信息，天氣信息是json的數據格式，數據如下：

我們可以解析json數據去得到自己想用的天氣信息。
