i基于android平台的校园二手物品交易系统设计与实现摘要如今,大学校园每年的大学毕业季,存在大量的书籍、衣服、书桌、衣架等各类闲置物品亟待进行实时交易,研究如何有效实现将这些闲置的物品及时进行合理处理进而有效减少对资源的浪费,以及我们所践行的绿色环保消费的理念具有较大的经济和对社会的应用意义。伴随着互联网信息技术的飞速发展以及电商的逐步完善,android二手物品交易平台和手机app中的市场占有率已经远远超过了92%;虽然目前赶集网、58同城等实时交易平台已经成功实现了二手物品实时交易,但其二手物品交易过程中的交易人员信息安全性、物品的质量等却一直得不到有效保障,处于社会弱势群体的校园大学生往往会感到投诉无门。针对以上的问题,本文精心设计并开发和实现了基于赶集网android实时交易平台的校园大学生二手物品实时交易系统。本系统采用java作为开发语言,采用c/s架构,客户端androidstudio adt sdk sqlite jdk,服务器端使用tomcat myeclipse mysql来实现。搭建了一个主要针对在校大学生二手交易市场的平台。关键词:android;二手物品;校园购物;javaiidesignandrealizationofandroid-basedplatformoncampussecond-handtradingnowadays,theconceptofsustainableutilizationofresourcesandgreenconsumptionhasbeendeeplyrootedinpeople'shearts.therearealargenumberofbooks,clothes,desks,clotheshangersandotheritemsthatneedtobetradedinthegraduationseasonoftheuniversitycampuseveryyear.itisofgreateconomicandsocialsignificancetorealizethereasonabledisposalofidlegoodsandthusreducethewasteofresources,aswellastopracticetheconceptofgreenconsumption.withtherapiddevelopmentofsmartphonesandtheinternetindustry,androidplatformhasalreadytakenover92%ofthemarketshareofcollegestudents'smartphones.althoughthesecond-handgoodstradinghasbeenrealizedonplatformssuchasganjinetworkand58city,thesecurityofpersonnelinformationandthequalityofgoodsinthetradingprocessarenotguaranteed,andstudentsfromdisadvantagedgroupsoftenhavenowaytocomplain.inviewoftheaboveproblems,thispaperdesignsandimplementsacampususedgoodstradingsystembasedonandroidplatform.theclientofthisusedgoodstradingsystemadoptsc/sarchitecture,theclientadoptsandroidstudio adt sdk sqlite jdk,andtheserverusestomcat mysql myeclipsetoimplement.thissystemusesjavaasthedevelopmentlanguageandbuildsaplatformmainlyaimedatthesecondarytradingmarketofcollegestudents.keywords:android;second-handgoods;campusshopping;javaiii目录1绪论.........................................................................................................................................11.1论文的背景及意义......................................................................................................11.2国内外研究现状..........................................................................................................11.3研究内容和研究方法.................................................................................................22系统相关技术.........................................................................................................................32.1客户端技术介绍..........................................................................................................32.2服务器端技术介绍...................................................................................................... 4 2.2.1 eclipse 的介绍 ...................................................................................................... 4 2.2.2 myeclipse ............................................................................................................... 4 2.3 关键技术介绍 ............................................................................................................. 5 3 系统需求分析 ......................................................................................................................... 7 3.1 需求分析 ...................................................................................................................... 7 3.1.1 需求分析 ............................................................................................................... 7 3.1.2 模块划分 ............................................................................................................... 8 3.1.3 功能需求 ............................................................................................................... 8 3.1.4 用例图 ................................................................................................................... 8 3.2 系统任务的可行性分析 ........................................................................................... 9 4 系统架构设计 ........................................................................................................................11 4.1 app 架构 ...................................................................................................................11 4.1.1 app 结构图 ...........................................................................................................11 4.1.2 功能结构图 ......................................................................................................... 12 4.1.3 总体流程图 ......................................................................................................... 13 4.2 数据库设计 ............................................................................................................. 17 4.2.1 数据库e-r 设计 .................................................................................................... 17
