安卓开发实战-记账本APP（四）

今天实现的内容有：添加账本信息，个人头像的切换，密码的修改，退出登录。

添加账本信息有三个功能：

①记一笔支出项目

②记一笔收入项目

③清空所有项目


在此期间遇到的困难有：Activity与Fragment之间数值的传递问题，我利用Bundle对象来进行传值，但是布局文件中fragment里的name=“Account_Fragment”，这里暂时没有想到如何传值。

因此暂时将name="Find_Message"这个还未改变的一个fragment，当再次点击Account图标时，就可以传进去参数。

未解决的事：

①记完账本后，按日期排序一直不对

②初始Fragment没办法传参

明天要做的事：

先将上述问题解决，在设置长按项目进行单独删除。

统计总的收入与支出的对比

找到合适的图标进行替换

学习hellochart，将数据以饼状图展示。

 

今日成果：



 



 点击更换头像：会有几个头像供选择



 

 当点击后自动跳回个人信息界面：



 

 其次是更换密码：需要输入原密码与新密码



 

 再者就是记账的页面：有支出，收入，删除所有，支出的会显示红色，收入的会显示绿色



 

 当点击收入时，会弹出一个框来进行记账



 

 同理，当点击支出时，也会弹出一个框



 

 当点击删除所有时，会将所有账目全部删除。
