lol外围下注|本篇文章将共享两个VIEW组件,一个天气组件和一个日期组件,这两个组件本来是一个AppWidget后来,我看著冷笑话,将他们盖住一个VIEW的组件,可以像用于WindowsPhone7的用户控件一样扯放在你想的项目中。本篇将展示这两个组件的撰写过程,工程文件如下:    包名讲解:  com.terry.weather  程序的入口包在  com.yaomei.adapter  天气预报组件用于到的数据源  com.yaomei.model  天气预报用于到的模型包在  com.yaomei.util  提供天气信息的工具包  com.yaomei.widget  天气预报组件、日期组件的存放在方位  从包名可以显现出,撰写一个天气预报所必须的代码量比撰写一个日期VIEW所必须的代码量要非常少,那么我们再行把天气预报的一些构建思路跟大家讲讲。  首先,本实例用于的天气预报是一个可以自己国际化的天气组件VIEW,可以看右图,将所必须的URL都放进ANDROID自己的国际化文件夹里面,比如中文的话就这样写出:  《stringname=googleWeatherApi》  《![CDATA[.yaomei.widget;
