Android开发实验---通讯录

实验报告通讯录姓名：学号：课程名称：移动应用开发所在学院：信息科学与工程学院专业班级：计算机任课教师：主要功能分析：1、增加、删除、编联系人点击通信录界面中的增加按钮，入增加联系人面。

输入联系人的基本信息，并可根据用户需求增加个性化信息如头像、姓名、手机号码、办室电话、家庭电话、职务职称、单位名称、地址、邮政编码、Email、其他联系方式、备注这些信息，击确认返回主界面。

点击通信录中一个已存在的联系人，进入联系人编辑界面，可修改系人的资料或进行删除联系人操作，完成后退回到主界面。

对列表中联系人的标记，点mnu键弹出功能界面上的删除按键也可进行删除。

还可以在菜单上选择删除全部联系人清空通讯录。

在删除联系人的过程中，系统将提示用户是否继续操作，若放弃操作，则系人信息将继续保存。

2、查找联系人用户点击menu键打开底部菜单框，底部菜单框为查询系人提供入口，进入通讯录的缺省页面为联系人列表，在列表中看到所有联系人的姓名、电话息排列，用户点击查找按键输入联系人基本信息，，通讯录显所有符合查询条件的联系人列表，用户选择一个联系人进入联系人基本信息页面进行其他操作；查询完成，用户按返回键返回主界面。

3、通功能用户在通录选择联系人进入联系详细信息界面，这时点击menu键打开通信功能框，选择打电话、发信息的功能进行操作。

4、菜单能通过对menu按的点击，显示底部菜框，包含有增加查找、除、菜单、返回功能，菜单按键则包含显示所有、删除所有等实用功能。

增加联系人：这个功能由ContactAdder类完成，具体实现不是比较麻烦，保存动作由ContentResolver类解决，但实现方式有所不同，可分为一次性批量增加与挨个增加。

由于界面设置繁琐，代码页过多，所以挑出其中的一部分进行说明首先是DB数据库建库过程：package com.xample.hivian.my_contact_manager.models.db;import android.content.ContentValues;import android.database.Cursor;import
