MVP+xRecyclerView+Retrofit+OkHttp+RxJava

1. 如上图，使用 MVP+xRecyclerView+Retrofit+OkHttp+RxJava

接口：APIKEY=‘71e58b5b2f930eaf1f937407acde08fe’

http://api.tianapi.com/nba/?key=APIKEY&num=10

2. 实现思路：

1. 主页面显示一个xRecycleveiw实现分页加载（10分）

2. Retrofit访问网络接口获取数据（10分）

3. xRecycleview 实现多条目展示上面效果（10分）

4. MVP分层（10分）P调M（5分）V实现P(5分)

5. 自定义搜索框（10分）

6. 在构造方法中初始化Fresco并做配置（10分）

7. 配置图片的显示方式为圆形显示（10分）

8. 在适配器显示视图的方法中通过Fresco来显示图片（10分）
