Bluetooth Management System Based on User Interface Design

Abstract
With the popularization of education the number of college students is increasing Different from the management of junior and senior high schools universities prefer autonomous learning In addition the class mobility of the popular selection and scoring system in colleges is enhanced so college students have more freedom in course selection and class concept is weakened Although there is plenty of time to do the projects they like so as to shine in the projects they like in this case the school management becomes more difficult Some students are so indulgent that they get bored of classes so they skip classes and substitute for each other And some teachers downplay the management further condoning this kind of behavior In traditional attendance methods such as oral roll call it is difficult to detect these behaviors effectively when there are too many students Therefore in order to eliminate this kind of behavior bluetooth based attendance system is widely usedAlthough this design is called a bluetoothbased attendance system bluetooth is only responsible for checkin connection information interaction other data interaction as long as the app and the server to complete This paper mainly describes the working principle in the design and the content of each module The design of the database and server side of the interaction and as the core let the students＇ bluetooth name changed to their student number let the device to search and locate so as to determine the status of students Mysql is a serverside database mainly used to handle login registration send and receive notification sqlite is a local database mainly used to store the bluetooth communication checkin and leave data Students who are absent from school are specially marked and their attendance is displayed The information is then packaged and sent to the relevant management This method can improve student attendance and the quality of teaching And it＇s more modern than a verbal roll callKeywords DatabaseBluetooth Managerment SystemClinetside System

1 前言
现代化信息理时代 教育工作者蓝牙考勤系统进行签学生进行请假进更安排学计划老师端仅通考勤检查学生勤状况发布群消息仅节省工成提高效率设计基蓝牙考勤系统基app服务端交互蓝牙间连接课题针户界面设计意做出互动性强界面[1]

11设计目意义应达技术求
目前考勤签采占时间长效率口头签样易造成课堂学生学时间减少时间花考勤造良教学环境设计易完成先进高效蓝牙考勤系统Android设计致性高受众广易手界面切换迅速字体颜色分布着舒适界面选择色调作APP题色操作达简单舒适范畴合理传达视觉元素达信息户说目然

12设计国外发展概况存问题
年着学生数量增考勤务变越越兼巨拖延时间长教师节必点名样引起学生侥幸心理学生学发展疑种巨影响改变机制点名时间幅度减少效率变高户界面设计缺环考勤利否会影响积极性（户体验）优化户感受量户感受傻瓜式体验企业学追求效率时间金钱种基础蓝牙考勤系统越越普国国外久口头点名类效率低方式终淘汰[4]
国外app设计更加性化户体验作终目标造许爱释手appapp载率高居见趣十分减压许元素组成譬俏皮文字适宜画面完美组合成app次视觉手法引发鸣
户体验户app直观感受夸张说良互动确确影响户积极性引发系列相关连锁问题设计安卓台点名app媒介找符合众视觉需求界面样式舒适简洁出发
受限某限制国设计操作系统验性国外定差距手机户界面没国外性化缺少良性互动缺少实性应该想方设法增加客户粘
13设计应解决问题
造户喜欢户界面根户惯设计界面阅读惯信息语言否恰数齐排列屏幕类图标摆放适宜减少app中广告植入广告植入户享受范围app应该简单减少复杂操作页数拉app客户距离应该针该app专群添加该群熟悉元素
21关Android Studio
211介绍
Android StudioGoogle家技术公司推出Android需合适工作环境工具开发应调试集成工具
212环境搭建
载安装Android Studio（选择安装Virtual Device）设定Custom喜设置安装路径出现中文Android Studio默认语言中没中文根喜选择存第次安装会动配置gradle

提示界面：提示界面转瞬逝通常fragment加载界面TextView显示正加载Progressbar进度条分显示网络延迟正加载正玩命加载界面提示户现情况没更提示户浏览界面已头出现错误出错界面面加猫表情拉开发者户距离
6接口设计
界面接口设计指机交互形式然控件做精美界面仅仅界面已法户进行互动Android频繁监听机制户填写完基信点击注册钮时候开始服务器发送登录请求实屏幕面户交互时见动作
流程：开始先事件源注册监听器般组件然户外部动作触发然触发事件源事件事件源受影响会生成应事件时事件监听器会事件参数记录数进行数分析分析事件处理方法事件源事件事件监听器
方法：
1 直接匿名部类通常次复性高设计监听方法
2 部类处该类中进行复直接访问界面组件
3外部类种形式较少见创建JAVA文件通常会导致代码够简洁
4 Activity作事件监听器
5 直接绑定标签layout布局文件中应Activity中定义事件处理方法 相应组件触发事件组件

7考勤签设计原理
老师学生间传递信息蓝牙媒介服务端利Servlet处置服务器响应程序轻量级框架进行HTTP请求响应响应教师端学生端发起服务端进行处理返回学生教师端蓝牙作设备独址中模块种载体
8总结工作展
文针设计考勤签系统交互界面设计优点足进行总结
优点：必功健全操作方便Android系统较灵活UI界面互动良教师发布通知查考勤情况学生进行互动
缺点：然手机端操作方便电脑端开服务器户界面较拥挤接口项目限学生时连接存丢失情况
展：拓展更功签排名学生发弹幕增加学生学生学生老师间良性互动蓝牙考勤系统普关系定越越高app已广社会着技术更新换代机交互形式必然更加户感身受
