1.Android的天氣預(yù)報(bào)的應(yīng)用還是挺多的，基于JSON和WebServ的均可。
首先我們來(lái)介紹基于JSON解析的天氣預(yù)報(bào)的開(kāi)發(fā)
2.這需要尋找到合適的數(shù)據(jù)源。
這里使用的是http://www.weather.com.cn/（中央氣象局）的數(shù)據(jù)信息?？赏ㄟ^(guò) m.weather.com.cn/data/101010100.html或者www.weather.com.cn/data/cityinfo /101010100.html查看到北京的天氣信息。
3.接下來(lái)就是對(duì)JSON數(shù)據(jù)的解析
