一、需求分析

在信息高度发达的背景之下，总是无时无刻诞生出许多创新的事物。对于中医而言人脑无法时时刻刻记住许多繁杂的药方。中华自古以来先人积累了很多有用的药方和宝贵的经验，在西药的冲击之下，我们仍然需要去学习中医，并取西医的精华，做到中西合璧。而互联网时代利用安卓相关技术可以制作一款方便的手机app，用以随时记录药方，查询药方，修改药方等。还可以通过摄像头拍摄药草、多媒体应用等让中药软件变得更加具有实用性。

该软件需要实现，其一辅助中医大夫储备药方、药名药理备查。让大夫能腾出精力集中诊断分析，而不必消耗精力去记忆琐碎的细节。其二，基于安卓，便于随时随地方便时录入储备或完善经验方。更加有利于查询。其三，使用通用的中医药数据库不需要上网就可以查询一部分药方。其四，查询功能方便快捷，有友好方便的图形界面等。

图1 功能流程图

通过上述流程图可以看出该软件包括注册登录，播放背景音乐，加减/新增药方，注册新用户，相机记录药材，药方介绍视频播放，管理药方信息，查看药方信息等模块。

2.3 功能模块说明

从需求分析可以找到，该系统分为用户使用的药方基本功能和多媒体相关的功能。

中医大夫助理信息系统包括以下主要功能：

（1）注册登录功能：用户注册，登录；

（2）查看药方功能：用户查找药方，并选择需要药方具体查看；

（3）管理药方：用户可增加药方，修改药方，删除药方；

（4）播放音乐：点击播放可以播放后台音乐，暂停和停止可以停止音乐；

（5）药方介绍视频：有暂停、播放、快进、快退等功能。

（6）相机记录药材：用手机的相机功能记录药材，增加中医大夫助理信息系统的可用性。

（7）补间结合帧动画动态显示：补间动画和帧动画的结合，增加中医大夫主力信息系统的界面友好性。

3.3.2 详细设计

（一）设计表

将E-R图转换为关系模型一般遵循如下原则：

（1）一个实体型转换为一个关系模式。实体的属性就是关系的属性，实体的码就是关系的码。

（2）一个m:n联系转换为一个关系模式。与该联系相连的各实体的码以及联系本身的属性均转换为关系的属性，而关系的码为各实体码的组合。

（3）一个1:n联系可以转换为一个独立的关系模式，也可以与n端对应的关系模式合并。如果转换为一个独立的关系模式，则与该联系相连的各实体的码以及联系本身的属性均转换为关系的属性，而关系的码为n端实体的码。

（4）一个1:1联系可以转换为一个独立的关系模式，也可以与任意一端对应的关系模式合并。

根据上述原则设计的数据表如下：

用户实体：用户（用户ID、用户名、密码）

药物列表实体：药物（药物ID、药物名字、拼音代码、所属类别、别名、药量单位、药效、功效、应用）

辩证分类实体：分类（辩证类别、拼音代码、父类、序号）

方剂药物对应实体：对应（方剂名称、药物名称、药量、序号）

方剂列表实体：方剂（用法及注意、歌诀、功能、拼音代码、别名、所属类别、方剂名称、序号、主治）

（二）设计数据字典

数据字典：中医大夫助手管理信息系统会涉及大量的静态数据，如用户姓名、药材名称、方剂名称、药材别名、拼音代码、辨证类别等等，这些数据，其数据的组织结构基本一致，现为该系统设计四个数据字典：用户字典、药材字典、辩证字典、方剂字典。

                                    表5 药物方剂对应表

创建 SYNDROME_SUBJECT 表的语句

create table SYNDROME_SUBJECT

(

    PK_ID           integer     primary key     autoincrement,

    NAME            text        unique          not null,

    KEY_CODES       text                        not null,                       -- 关键代码(拼音), comma seperated to including alias, etc.

    DESCRIPTION     text,

    PARENT_ID       integer

                    references SYNDROME_SUBJECT(PK_ID) on delete set null

);

创建 RX_RECIPE 表的语句

                    references RX_RECIPE(PK_ID) on delete restrict

);

创建 MEDICINE 表的语句

create table MEDICINE

(

    PK_ID           integer     primary key     autoincrement,

    UNIT            text                        not null

                    check(UNIT in ('克', '毫升', '枚'))         default '克',    -- 药量单位: "克" 或 "毫升" 或 "枚"

    POISON          int                         not null        default 3,      -- 毒性: 是药三分毒

    SYNDROME_ID     integer

                    references SYNDROME_SUBJECT(PK_ID) on delete restrict,

    PROPERTY        text,

    EFFICACY        text,

    INDICATION      text,

    SYNERGIST       text,

    DESCRIPTION     text

);

创建 admin 表的语句

create table equipment(

id integer primary key,

name varchar(20),

)

创建MAP_RX_RECIPE_MEDICINE表的语句

create table MAP_RX_RECIPE_MEDICINE

(    

    RX_RECIPE_ID    integer                     not null

                    references RX_RECIPE(PK_ID) on delete restrict,

    MEDICINE_ID     integer                     not null

                    references MEDICINE(PK_ID) on delete restrict,

    ORDER_NUM       real                        not null,

                    check(IS_OPTIONAL in ('Y', null))           default null,

    constraint      UK_MAP_RX_RECIPE_MEDICINE   unique(RX_RECIPE_ID, MEDICINE_ID)

);

四、系统调试

（1）背景音乐

问题：app启动后可以选择播放背景音乐，使用service无法在视觉上判断背景音乐是否进行播放。播放音乐无法暂停等。

解决方法：同时使用service 和broadcast，当点击菜单选项时，通过广播的方式通知页面发生改变。

 

图15 背景音乐调试

（2）补间动画和帧动画

问题：要完成一个位置和图片内容不断变化的动态显示图，点击按钮可以实现该图片的动态显示

解决方法：结合所给的代码，将补间动画和帧动画进行结合，实现图片一位置不断顺序变化，图片内容也不断变化

 

 

（3）播放视频

问题：播放视频时无法快进、快退等，控制视频播放的时长和快进到自己想要的位置

解决方法：增加MediaController对视频播放进行控制

 

（4）相机功能

问题：相机功能单一，无法调整亮度等设置，拍摄出来的结果不尽人意

解决方法:修改代码，直接调用手机本身照相机功能拍摄。

 

五、界面效果

六、总结

经过这一学期对安卓的学习以及这两周的安卓大作业的完成，让我对安卓编程有了一定的了解，期间也遇到很多虚拟机调试的问题，其中耽误我最多时间的是视频播放，虚拟机是播放不了视频的，需要真机调试。除此之外，大部分时间在数据库那一部分，这一部分很多SQL操作的忘记了，需要一遍遍翻书和查找网上资料进行了解，其中，药方的内容属于网上查找的部分药方，用于调试内容，网上有现成的药方xls文件等。关于帧动画和补间动画的结合也研究了一下，属于一个小扩展。

最后，这次的安卓线上线下教授和自主学习让我受益匪浅，从一个对安卓编程小白到初入门槛，后面的时间我会不断完善我的APP，让它更实用。
