安卓通讯录实训报告

安卓实训设计报告安卓通讯录设计题目：安卓通讯录班级：姓名：学号：指导老师：日期： 2012年6月7日容要求一、题目分析，功能要求。

1.1 实验目的熟悉Android软件开发的基本架构利用Eclipse和ADT插件设计通讯录1.2 功能本手机通讯录工具主要实现五大功能：联系人的查询：字段查询，分组查询，字母排序查询；增加、删除联系人以及修改联系人信息；导入、导出联系人；发送联系人信息；设置。

二、实验设计2.1 UI设计我们用一个ListView来显示整个通讯录，其中用TextView显示每一记录，他们的xml文件分别为：main.xml(通讯录主界面)，addres.xml(添加联系人界面)，list_item.xml(浏览联系人界面)，find.xml(查找联系人界面)。

2.2功能的设计为了在主界面中浏览联系人的信息，并且创建主要菜单栏，我们设计了MainActivity类，主要用于显示联系人信息和菜单栏，通过菜单栏，实现通讯录的相关功能。

AddressBook类主要是为了实现联系人的添加功能，并且实现信息的保存后跳转到主界面。

Findactivity类主要是为了实现联系人的查找功能，输入联系人的，点击查找按钮，显示所查联系人的相关信息。

三、实验程序四、实验效果图五、总结通过设计该通讯录，主要学习了UI设计、数据库的综合操作、动态菜单的使用以及各种权限的注册。

通过本次设计，使我对Android平台的数据库操作有了更进一步的理解，同时也对Android系统有了更深入的了解。
