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。
