第二阶段团队SCRUM

第二阶段冲刺已经完成，学期也进入尾声，下面进行总结。

首先给出任务板。

任务	未完成	已完成	负责人
服务器搭建，准备好开发相关的环境，如数据库等。		√	王兵兵
登录注册功能，实现用户注册信息入库，登录时遍历核实信息。		√	张宏伟
记录笔记功能，实现用户记录的笔记入库，包括是否公开，插入的图片信息。		√	朴远东
查看笔记功能，实现用户浏览自己的笔记，界面上要求实现笔记的删除，对笔记的修改。		√	朴远东+王兵兵
分享大厅界面，实现条件搜索，显示笔记，查看笔记，收藏笔记功能，记得刷新按钮。		√	王兵兵
收藏笔记功能，显示在分享大厅页面中收藏的笔记，实现对笔记的删除和查看操作。		√	王兵兵
“关于我们”写入简易介绍，留下团队邮箱；“意见反馈”添加留言板和提交按钮，信息提交可考虑数据库，或提交到团队邮箱中，核心目的是让开发人员可见。		√	张宏伟
“我的”界面排版，至少完成修改信息界面，实现对用户信息的修改；帮助界面写入APP的使用方法。		半√	王兵兵+张宏伟
其他敲定界面补充。	√
团队任务：UI设计	√
选做：增加功能。	√

本学期完成了大部分任务，但有些功能存在缺陷，还有部分功能未完成，需要在假期进行补充再去申请软件著作权。第二阶段工作上，王兵兵做得比较多，张宏伟补上了一些功能，朴远东则是在功能的基础上进行了完善和填充。藉此进行了第二阶段的团队绩效。

产品的革新功能如下：

增设了打开动画：

注册界面优化，含有验证码，验证码图片可以点击，点击即可更换验证码图片。

增设了底部导航栏：

个人笔记界面完成，并实现了长按删除功能，个人笔记预览和收藏笔记预览可以实现点击图片查看大图的dialog

分享大厅界面完善，含下拉刷新功能，实时更新公开笔记的信息：

我的界面可以更改用户头像，但只能在APP内生效。退出再进后重置

收藏笔记界面，与个人笔记界面类似：

意见反馈界面：

由于完成所用的代码过多。这里只贴出四个fragment代码，对应下面四个板块的功能：
