关于在安卓实现签到点名系统的研究

现在在我们的日常生活当中经常出现签到点名,在座的大学生想必印象深刻,然而随着大数据时代的来临,随着手机移动时代的来临,越来越多的科技融入我们的生活,生活越发的便利,其中最为明显的想必就包含上课签到点名就使用手机进行了。于是我搜索了相关资料,研究了一下如何在手机上实现点名系统。

首先是数据库部分:

超级管理员表创建语句如下:
create table t_admin(
    id int primary key auto_increment comment '主键',
    username varchar(100) comment '超级管理员账号',
    password varchar(100) comment '超级管理员密码'
) comment '超级管理员';
insert into t_admin(username,password) values('admin','123456');
建议表创建语句如下:
create table t_contact(
    id int primary key auto_increment comment '主键',
    customerId int comment '用户',
    phone varchar(100) comment '联系方式',
    content varchar(100) comment '内容',
    insertDate datetime comment '日期'
) comment '建议';
客户表创建语句如下:
create table t_customer(
    id int primary key auto_increment comment '主键',
    username varchar(100) comment '账号',
    password varchar(100) comment '密码',
    name varchar(100) comment '姓名',
    sex varchar(100) comment '性别',
    address varchar(100) comment '地址',
    mobile varchar(100) comment '手机'
) comment '客户';

公告表创建语句如下:
create table t_gg(
    id int primary key auto_increment comment '主键',
    title varchar(100) comment '标题',
    pic varchar(100) comment '图片',
    content varchar(100) comment '内容',
    showDate varchar(100) comment '日期'
) comment '公告';
课程表创建语句如下:
create table t_kc(
    id int primary key auto_increment comment '主键',
    teacherId int comment '老师',
    kcName varchar(100) comment '课程名称',
    pic varchar(100) comment '图片',
    content varchar(100) comment '课程内容'
) comment '课程';
课程签到表创建语句如下:
create table t_kcqd(
    id int primary key auto_increment comment '主键',
    customerId int comment '用户',
    kcId int comment '课程',
    insertDate datetime comment '日期',
    jwd varchar(100) comment '经纬度'
) comment '课程签到';
用户选择课程表创建语句如下:
create table t_kcxz(
    id int primary key auto_increment comment '主键',
    customerId int comment '用户',
    kcId int comment '课程'
) comment '用户选择课程';
信息交流表创建语句如下:
create table t_message(
    id int primary key auto_increment comment '主键',
    customerId int comment '用户',
    messageContent varchar(100) comment '内容',
    types int comment '',
    insertDate datetime comment '时间'
) comment '信息交流';
老师表创建语句如下:
create table t_teacher(
    id int primary key auto_increment comment '主键',
    username varchar(100) comment '账号',
    password varchar(100) comment '密码',
    teacherName varchar(100) comment '姓名',
    age varchar(100) comment '年龄',
    sex varchar(100) comment '性别',
    phone varchar(100) comment '电话',
    pic varchar(100) comment '头像'
) comment '老师';
