1摘要在如今这个生活节奏越来越快的社会，科技也随之发展的越来越智能化。而手机的智能化就是其中体现的一个方面，现在市场上比较主流的手机系统就是Android，苹果和w8。Android是一个开源的系统，它底层是基于Linux的操作系统。本毕业设计的音乐播放器采用了Android开源系统技术，利用Java语言和EclipseJDK编辑工具对音乐播放器进行编写。同时也给出了比较详细的系统设计过程、部分界面图及主要功能运行流程图，本设计还对一些架构的和界面的高度过程中遇到的问题和解决方法进行了详细的讨论，还有一些开发过程中遇到的错误问题进行了举例。该音乐播放器集播放、暂停、停止、上一首、下一首、歌词显示等功能于一体，有良好的性能，炫酷的播放界面。能在Android手机系统中能独立运行。该播放器还拥有对手机文件浏览器的访问功能、歌曲播放模式（单曲循环，单曲循环，顺序循环，顺序播放，随机播放）、以及歌词开闭状态等比较人性化的设置.该音乐播放器的名称是：“旋风播放器“，名字就和它的风格一样。关键词：Linux操作系统；Android；流程图；音乐播放器；开源系统李发万：基于Android的音乐播放器设计与实现AbstractInthisincreasinglyfastpaceoflifesociety,scienceandtechnologyalsowillbethedevelopmentofmoreandmoreintelligent.TheintelligentphonewhichreflectsoneaspectofthemarketisnowmoremainstreamphonesystemisAndroid,AppleandW8.Androidisanopensourcesystem,itistheunderlyingLinux-basedoperatingsystem.ThemusicplayerofthegraduatedesignusestheAndroidopensourcetechnology,theusetheJavalanguageandEclipseJDKofeditingtoolstowritethemusicplayer.Butalsogivesamoredetailedsystemdesignprocess,partoftheinterfacemapandmainfunctionsofaflowchartoftheoperation,thedesignofahighdegreeofprocessarchitectureandinterfaceproblemsencounteredandsolutionsarediscussedindetail,aswellassomedevelopmentprocesserrorsencounteredexamples.Themusicplayerissettoplay,pause,stop,previousone,thenextsong,lyricsdisplayandotherfunctionsinone,goodperformance,coolplayerinterface.Androidmobilephonesystemcanrunindependently.Theplayeralsohasaccesstothephonefilebrowserfunction,songplaybackmode(singlecycle,singlecycle,ordercycle,theorderofplay,randomplay),aswellastheopeningandclosinglyricsstatehumanesetthemusicthenameoftheplayer:whirlwindplayer,thenameanditsstyle.Keywords:Linuxoperatingsystem;Android;flowchart;musicplayer;opensourcesystem3目录摘要...........................................................1Abstract...........................................................2目录...........................................................3引言...........................................................1第一章系统需求分析................................错误!未定义书签。1.1功能需求（用例图分析）.........................................................................................21.1.1播放器的基本控制需求.....................................................................................21.1.2播放友好性需求......................................................................................................41.1.3功能需求(时序图)分析.....................................................................................41.2系统结构图和流程图..................................................................................................51.3播放器系统界面需求....................................................................................................71.4系统性能需求................................................................................................................81.5运行环境需求................................................................................................................8第二章Android数据库设计...........................................92.1数据库及字段属性设计..............................................................................................92.1.1字段设计（表、图）..........................................................................................92.1.2音乐播放器E-R图............................................................................................102.2数据库连接...................................................................................................................112.2.1创建数据库..........................................................................................................112.2.2操作数据库..........................................................................................................132.2.3数据显示...............................................................................................................14第三章Android项目介绍............................................143.1在我们理解Android是什么？...............................................................................143.1.1Android简介.......................................................................................................143.1.2AndroidFeatures特性..................................................................................153.1.3Android基本框架（AndroidArchitecture）.........................................153.1.4Android系统的四大组件..................................................................................193.2搭建Android开发环境..................................................................................................20第四章播放器系统功能详细设计.....................................224.1音乐播放器主界面功能实现....................................................................................224.1.1播放器主界面......................................................................................................224.1.2播放界面音轨的实现........................................................................................294.1.3播放器播放、暂停、停止等功能.................................................................30结论..........................................................32参考文献..............................
