RecyclerView 视频
例：
.......
1.项目框架模式：MVP（得分点）；注意：分包分层，避免内存泄漏；
2.图片加载：Fresco图片加载框架；
3.网络加载框架：retrofit；使用Retrofit+RxJava+okHttp实现网络加载；
5.列表数据展示使用RecyclerView；
1、MVP分包明确，避免内存泄漏，必须对P成V层抽取基类，否则无分；
2、访问网络接口使用retrofit+Rxjava，必须封装retrofit单例工具类，否则无分；
3、图片展示使用Fresco图片加载框架，视频展示自由选择播放器；
4、使用RecyclerView实现图一图二所示的视频模块和图片模块，
5、左右滑动可以相互切换当前模块；
6、给RecyclerView添加分割线
7、数据必须解析正确，必须使用retrofit和Rxjava；
8、图片模块可能包含GIF，使用is_gif 字段判断
9、最终效果和图一图二保持一致，视频能够正确播放
