本文着重书写了自定义View以及相关技术的展示，本文使用MVP**进行数据整理和书写（由于学习不是很到位可能有写疏漏）以及基类的抽取使得Activity界面更加整洁大方。本文参考简阅已经搭好简略的框架，易懂易学，初学者的同学可以学习一下。

重要的事情说三遍：主界面的界面是会动的哦！主界面的界面是会动的哦！！主界面的界面是会动的哦！！！海浪是真的在涌动，天空是真的在下雨哦（有一部分是不动的，但是不影响整体动画效果的学习）

欢迎界面重点是自定义View 右上角的倒计时器（相关对象：CountDownView）

主界面上的Viewpager和PagerTitleStrip都是自定义的对象用于实现渐变切换（参考于轻天气的切换模式）有兴趣的同学可以深入研究一下

界面上提供简易的切换当前天气模式，以及自定义View的样式展示，有相关使用地方的同学可以研究一下自定义控件

选择城市界面上也是仿照联系人列表进行自定义展示

添加通知栏提供学习，通知栏界面随城市不同而转变，生命周期直到App进程完全删除 

 最后希望 大家会喜欢Healer天气，里面用的知识点一部分都是采集于github上的大牛，学海无涯，互相学习互相帮助。希望我的Healer天气可以帮到你

最后的最后 下载的童鞋希望多多star and fork；

卡顿

卡顿！
放在悬浮窗上运行，特别卡顿，切换view基本就无响应了！

运行报错

刷新天气有时候应用报错网络异常或者Attempt to invoke virtual method 'java.lang.string com.sjzx.mojij_weather.bean.weather.ShowApiWeatherNormallnner.getCityName()' on a null objject reference
