Android_小账本小结

 登录界面：支持登录、注册以及游客登录，单纯的小账本的话其实用不到这些个登录，单纯为了巩固学习知识。

 

尚未部署到服务器，账号等数据暂时保存在本地数据库中。

 

 

 

 

游客登陆：游客登录会直接跳到主页中，不影响使用。

 

注册和登录时会弹出自定义view的dialog，这时可能会有黑影，这个和默认的主题有关。参考我的这篇博客：https://www.cnblogs.com/XiaoGao128/p/12283918.html

注册：注册时会判断数据库中是否存在此账号，注册完成后直接跳转到主界面。

 

 

登录有记住密码和自动登录两个选项。这两个选项通过SharedPreferences实现。具体参考我的这篇博客https://www.cnblogs.com/XiaoGao128/p/12268652.html

其中，三个主页面放在一个viewPager中。

InOutFragment（收支页面，记录收支信息）

收支页面分为两个大项十一个小项

其具体布局如下：

 

 

其他十一个小项默认隐藏，在点击相应按钮后相应小项会显示出来：

  

 

 

 

 

 

点击小项后会从下方弹出一个输入框，它相当于一个小型计算器，具体参考我的这两篇博客：

https://www.cnblogs.com/XiaoGao128/p/12263125.html

https://www.cnblogs.com/XiaoGao128/p/12245459.html

 

 

其中点击时间按钮可弹出一个DatePicker设置日期，设置完成后将时间、收支、类型、金额等存储到SQLite中。

 

因为viewPager会复用缓存的Fragment的view，所以数据更新比较麻烦，为了能够在输入完成之后滑到CordFragment时能够正确的显示，我在划过去时new了一个adapter，这样会导致一定的资源浪费，但暂时还没找到相对好的解决方法。

CordFragment（记录页面，即记录信息）

 

这里用到的是recycleView放进了这个Fragment中，所以数据更新很令我头痛。

在初始化界面时从SQLite读取数据传到recycleView中显示。

recycleView里放的是TextView，可以实现跑马灯式的循环以解决一行显示不下，两行不好看的问题。

 

点击TextView后会弹出详细信息界面，在这个界面中可删除此条记录。

删除这里同样有数据更新的问题，我直接跳到了另一个activity又跳回来，以实现删除时数据的动态更新。

SociatyFragment（社区页面，大家在社区中讨论省钱心得等等，尚未开发）

 

MyFragment（我的信息页面，它是一个侧滑菜单）

相关实现方法在我的这篇博客中https://www.cnblogs.com/XiaoGao128/p/12260383.html

它在初始化时同样会从数据库中读取用户昵称

点击退出登录会重新跳回登陆界面。

游客登录会显示请先登录。
