这一讲我们就主要实现一下码农天气的首页：



这个页面有城市名，当天的天气的logo，当前温度，当前天气，湿度，风力，以及未来5天的天气的预报数据，这些数据是从哪里得到的呢？
这个问题我找了很长时间，终于功夫不负有心人，让我在彩虹天气的strings.xml里面找到了：
<?xml version="1.0" encoding="utf-8"?>

<resources>

<string name="app_name">彩虹天气</string>

<string name="loading_msg">正在努力加载天气信息 …</string>

<string name="widget_clock">彩虹天气-时钟2x1</string>

<string name="widget_today_weather_big">彩虹天气-当天4x1</string>

<string name="widget_4_weathers">彩虹天气-三天4x1</string>

<string name="widget_today_select">彩虹天气-自选2x1</string>

<string name="widget_4x2_weathers">彩虹时钟+天气4x2</string>

<string name="widget_weather_clock">彩虹时钟+天气4x1</string>

<string name="forecast_url">http://m.weather.com.cn/data/%s.html</string>

<string name="current_url">http://www.weather.com.cn/data/sk/%s.html</string>

</resources>

复制代码

这个是我反解的彩虹天气的资源文件，最后2行就是我们要使用的请求天气数据的接口。真是踏破铁鞋无觅处，得来全不费工夫！
对于第1个接口，返回信息比较全面，也是以json格式提供。请求北京的天气数据：http://m.weather.com.cn/data/101010100.html，返回的格式如下（注意：//是我添加的注释）：

有些小伙伴可能就会问了，那个101010100这串数据是哪来的呢？其实这个就是中国天气网自己定义的北京的城市代码，我上网搜了一下，网上还是有很多好人的（或者像我一样无聊的人），他们已经把全国所有城市的代码都给扒了下来：

大家看了这堆代码也不要害怕，这些代码我已经按照省和城市的分类做了一个数据库，最后一讲的时候会随代码一起上传，以后大家只管调用就好了。
彩虹天气的资源文件里还有一个接口：http://www.weather.com.cn/data/sk/%s.html
这个是干吗用的呢？把%s换成北京市的城市代码，请求后的数据：
{"weatherinfo":{"city":"北京","cityid":"101010100",
// 当前温度
"temp":"6",
// 风向
"WD":"西风",
// 风力
"WS":"1级",
// 湿度
"SD":"15%","WSE":"1","time":"17:10","isRadar":"1","Radar":"JC_RADAR_AZ9010_JB"}}
有了这些数据，加上彩虹天气的布局文件（反解一下彩虹天气就能得到了，如果有小伙伴还不会反解，google一下吧，很简单的），大家应该就可以很轻松的做完彩虹天气的首页-预报和首页-指数的功能啦！
不过彩虹天气的指数有个小问题：



他的指数我换了2部手机，都看不清楚上面写的是什么，不知道小伙伴们能不能看到呢？
这一讲最后再给大家推荐一个开源的项目：http://loopj.com/android-async-http/，各位小伙伴在做网络编程的时候可以考虑一下这个library项目，我的大部分项目都是用的这个开源项目来请求网络数据的，据说Instagram和Pinterest也是用的这个开源项目，虽然具体没有考证过，但是从我个人的经验来看，这个项目还是比较好用的。
这一次就写到这，接口和布局文件我都告诉各位小伙伴了，希望大家也自己动手写写吧。下一次我们会分析一下中间的这个趋势是怎么做的：
