scrum项目冲刺_day05

今天仔细想了一下，这个项目确实没有什么有技术含量的知识，只是Android的一些基础，建民老师说如果能做出点新意也行，不过我们大概也没有精力去推广，提前接触一些大赛的题目也挺好，还可以学到更多更深层次的知识，所以现在

打算用几天时间把这个app做完，我估算了一下，到下周二应该可以大体做完。

基本完成了主页，剩下一些小bug，明天修复然后把社区大体做完。

肝！

1、主界面（已完成）
2、商品展示界面（已完成）
3、商品详情界面（已完成）
4、 添加商品界面（已完成）
5、从数据库读取相关类别商品信息并传入商品展示界面（已完成）
6、从数据库读取相关商品的评论传入商品详情界面（已完成）
7、添加相关商品的评论到数据库（已完成）
8、添加商品信息到数据库（已完成）
9、关键词搜索（已完成）
10、动态加载商品

社区相关：
1、社区主界面（明日待办）
2、帖子详情，包括点赞评论回复的实现（明日待办）
3、发帖界面（明日待办）
4、将贴子信息传输至数据库（明日待办）
5、从数据库读取帖子信息并展示（明日待办）
6、从数据库读取帖子的相关评论及回复（明日待办）

今天和昨天的代码
