Tablayout
不了解Tablayout基本使用的，请戳http://www.jianshu.com/p/6923f29a478e
内容
- 页面设计：
1.最上方是一个自定义toolbar，右端是一个布局切换按钮。
2.接下来是一个Tablayout,有默认、价格、销量、三个成员
3.在下面是一个textView计数器。
4.最后是一个MaterialRefreshLayout+RecyclerView的组合，拥有下拉刷新，上滑加载的功能。
布局代码如下：
- 功能介绍：
1.通过点击tablayout的子控件，fragment从网络端获得不同的数据，重新加载显示。
2.通过点击toolbar右端的切换布局按钮，改变recyclerView的布局设置，进行重新加载显示。 - 代码分析：

1.为区别三种排序方式，定义三种状态进行区分。
2.当点击某个Tab 时，改变排序状态，再让RecyclerView按照状态加载。
3.点击切换布局时，切换布局状态，再让RecyclerView按照状态加载。
