CS3331-1-软件工程大作业，参考《第一行代码 第三版》
- 安卓部分
- 整体框架使用Activity套Fragment，后续考虑换成更流行的Viewpager2加Fragment
- UI采用NestedScrollView嵌套RecycleView实现滑动与列表实现
- UI模仿柠檬的布局，白绿粉蓝配色
- 数据库部分
- item的储存采用原生的关系数据库SQLite加ORM模型Room
- person与其他metadata采用原生的KV数据库SharedPreferences
- 后序将person的储存也换成关系数据库方便进行DA
- 使用Gson实现储存的Json格式与运行时ArrayList转换
- 网络部分(未完成)
- 三层架构，即client-server-database
- 使用Gin框架实现RESTFUL API，做为前端服务器
- 使用Glide实现远端图片的获取，图片的异步加载与本地缓存
- UI设计较为简单，更多重点在后端逻辑部分
- 实现了留言功能，方便双方的交流
- 动态类别修改，分类搜索，简单的模糊搜索(水壶->水杯)
- 密码采用SHA256加密储存，实现记住密码自动登入功能
- Android
- total framework design use Activity together with Fragment, would change to Viewpager2 together with Fragment in future
- UI design uses NestedScrollView nests RecycleView to implement screen scroll and list show
- UI design imitates SJTU lemon design style,use white-green-pink-blue color scheme
- Database
- item storage use native ralational database SQLite with native ORM model Room
- person and other metadata storage use native key-value database SharedPreference
- hope to change person storage model to relational database for the sake of data analysis in future
- use Gson to convert between storage format Json and runtime format ArrayList
- Network(unfinished)
- three-tier architecture,namely client-server-database
- use Gin framework to implement RESTFUL API,work as frontend server
- use Glide to get remote images,asynchronous load and local cache
- UI design is relative simple，attach more importance on backend logic design
- implement comment utility，make communication easier
- dynamic category edit,classified saerch,simple huzzy search
- encrypt password use SHA256 when storage, implement remember password and auto login in utility
