HarmonyOS开发——我的通讯录
概述：
本次项目是我这个学期鸿蒙应用开发的结课作业。是根据平时所学内容以及自己手机上面的通讯录做出来的demo。
开发工具：
DevEco Studio
APP图标如下：
功能介绍：
1. 具有显示联系人列表、添加联系人信息、删除联系人、修改联系人信息等功能；
2.储存联系人信息时并未使用数据库，而是通过使用配置文件写入输入的数据，并进行读取或修改；
3.还具有修改底部状态栏配色的功能。
实现功能的说明：
1.在编辑时，只有输入姓名，才会出现确认按钮：实现这一操作，只需要检查姓名输入框中的内容是否为空，如果是空，则将该组件隐藏，如果不是空则将该组件设置为可见。
2.实现底部配色主题得切换：将底部得配色归纳成四种Rgb配色，统一得存放在BottomBarColor.java文件中，使其保持static/final，并且编写相应得static函数操作。当用户选择了某个主题配色并点击“应用”按钮后，会调用设置相应得颜色，即可达到切换配色得目的。

总结：
本次项目demo是我根据老师平时上课讲解以及借鉴了网上大佬的文章完成的，这次项目实战算是对自己学习一个学期之后的总结，从中我学到了很多。但是也有很多不足，比如当时希望能做出一个很耐看的界面，后面也只是草草了 事。理想和现实的差距，往往体现在能力的不足和人的惰性身上，也希望以后能够精益求精，对任何事情都能交出完美的答卷。
