前言
很多项目中进行会出现，一个状态对应一种现实样式。是统一在一个界面处理，还是分开n多页面处理呢，
这篇给出了一点个人建议，及是实现方案。
效果图
方案一： 一个activity 全部进行控制。所有的状态。完全靠堆代码。（不推荐）
方案二 一个activity 中包含BaseFragment 然后 subfragment中实现不同状态。（推荐）
方案3
…
…
方案一：
优点：
代码量少，处理简单ui问题。完全可以写到一个activity中。
缺点：
后期维护，绝对是噩梦，7,8种状态，来回变换，各种逻辑穿插。导致类膨胀。
方案二：
优点：
结构简单，单个类代码量少，清晰。便于维护，扩展性高，符合单一职责
缺点：
前期工作量相对大于方案一
2.方案二 uml类图：
抽取基类就是为了复用。 能复用的尽量放入基类，统一入口。
基类职责：
1.N多subFragment 公用一套 xml。（如果使用N个布局对应N个subfragment，重复工作量太大。）初始化root布局
2.特殊布局，分发给subFragment去处理，公共区域更新由基类完成。
3.统一处理一些逻辑。这里是处理状态对应文案，以及文案颜色等
4.作为工厂类，生成对应样式的subFragment
subFragmnet 职责：
1.更新ui
2.隐藏不需要的xml 组件。默认展示所有xml组件。
Activity ：
1.作为BaseFragment容器，当然这是常识，fragment无法单独用来展示ui，必须依附于Activity。
2. 作为Mvp模式中的view，网络请求成功会先走到Activity中，然后通过baseFramgnet，分发数据到具体subFragment中。（fragmen同样可以作为View，这里为了统一处理，较小难度。用Activity做为View）
Eg：mvp模式不在这里介绍。有需要了解的自行前往google 官方sample地址查看。
说道这里觉得少了点：
贴代码：
