【0147】【项目实战】-【百思不得姐】-【4】基于MVP项目架构实现精华

1. 精华Tab的布局分析

【说明】前面的Tab使用的空间；

【说明】精华布局要实现的实例样式如下：

2.精华布局实现

2.1 圆角图片的处理

【说明】此处使用了自定义的控件

3.配置网络请求框架

【说明】系统自带的网络请求已经android放弃，使用okHttp；

【替换网络框架】只需要实现此接口就可以；

4.配置网络请求框架

【分页数据的加载】

5.接口测试

【添加下拉刷新的控件】

【测试】打断点

【取回的json数据进行格式化】

6.UI实现

【绑定代理】

7.下拉刷新组件集成

【布局的添加】

【适配器的代码】
