基于Android平台的手机音乐播放器的设计与实现

学号：常州大学毕业设计（论文）（2012届）题目基于Android平台的手机音乐播放器的设计与实现学生学院专业班级校内指导教师专业技术职务校外指导老师专业技术职务二○一二年六月I基于Android平台的手机音乐播放器的设计与实现摘要当今社会的生活节奏越来越快，随着硬件移动设备的越来越先进，人们对移动设备的要求也越来越高，从以前的追求技术到现在的追求视觉，因此，也逐步的提高了对系统的要求，本文主要是对Android系统上一款音乐播放器应用程序的设计与实现进行讨论。Android是一个开源的系统，它底层是基于Linux的操作系统，本论文的音乐播放器采用了Android开源系统技术，利用Java语言和Eclipse编辑工具对播放器进行编写。同时给出了详细的系统设计过程、部分界面图及主要功能运行流程图。本文还对高度过程中遇到的问题和解决方法进行了详细的讨论，该音乐播放器集播放、暂停、停止、上一首、下一首、音量调节、歌词显示等功能于一体，性能良好，在Android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、以及歌词开闭状态的友好设置.MP3的全名是MPEGAudioLayer-3,是一种声音文件的压缩格式,由于本播放器只限于应用层程序的探讨，所以对具体的压缩算法不作深究。关键词：Android;开源系统;音乐播放器IIDesignandImplementationofMobilePhoneMusicPlayerBasedontheAndroidPlatformAbstract：Thepaceoflifeintoday'ssocietyisquickerandquicker,withmoreadvancedhardwaremobiledevicesformobiledevices,whichisrequiredmoreandmorehighfromthepreviouspursuittopursuethevisualtechnology,therefore,thepeoplealsograduallyimprovethesystemrequirements,thepapermainlyistotakeonamusicplayerfromsystemdesignandrealizationoftheapplication.Androidisanopensourcesystem,itisbasedontheLinuxoperatingsystem,themusicplayerofthepaperadopttheAndroidopen-sourcesystemtechnologyandtakeadvantageoftheJavalanguageandeditingtoolstoEclipseplayers.Simultaneously,itgivesthedetaileddesignprocess,thepartofthesystemandthemainfunctionsofoperationinterfacediagramofheight,thepaperhasdetaileddiscussionsaboutproblemsandsolvingmethodsinflowprocess,themusicplayercoversepisode,pause,stop,up,next,volumeadjustmentandlyricsdisplayfunctionsetc,becauseofgoodperformance,itcanoperateindependentlyintheAndroidsystem.Thisplayerhasaccesstothefilebrowserphonefunctions,songsandplayedpattern,openandcloseconditionoffriendlywords.ThefullnameofMP3isMPEGAudioLayer-3andakindofsoundfilescompressedformat.Becausetheplayersisonlylimitedtotheexplorationofappliedprogram,itdoesn’tstudythespecificcompressionalgorithm.KeyWords：Android;Opensourcesystem;musicplayerIII摘要.............................................................................................................................................I术语表...................................................................................................................................V1概述........................................................................................................................................11.1课题的背景和意义......................................................................................................11.2课题的研究历史和发展现状......................................................................................11.3课题研究的主要内容..................................................................................................21.4方案的原理、特点与选择依据.................................................................................32系统需求分析........................................................................................................................32.1可行性分析..................................................................................................................32.1.1经济可行性分析..............................................................................................32.1.2技术可行性分析..............................................................................................32.1.3社会可行性分析..............................................................................................32.2系统需求分析..............................................................................................................42.2.1功能需求...........................................................................................................42.2.2界面需求...........................................................................................................42.2.3性能需求...........................................................................................................42.2.4可靠性要求......................................................................................................42.2.5运行环境需求...................................................................................................43总体设计................................................................................................................................53.1系统结构设计和流程设计.........................................................................................53.1.1音乐播放器的系统流程设计...........................................................................53.1.2系统功能设计和系统功能结构设计...............................................................63.2Android数据库设计....................................................................................................73.2.1字段设计..........................................................................................................83.2.2SQLiteDatabase数据库....................................................................................94Android项目.........................................................................................................................104.1Android简介..............................................................................................................104.1.1A
