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。

李发万：基于Android的音乐播放器设计与实现
Abstract
In this increasingly fast pace of life society, science and technology also will be the development of more and more intelligent. The intelligent phone which reflects one aspect of the market is now more mainstream phone system is Android, Apple and W8. Android is an open source system, it is the underlying Linux-based operating system.
The music player of the graduate design uses the Android open source technology, the use the Java language and EclipseJDK of editing tools to write the music player. But also gives a more detailed system design process, part of the interface map and main functions of a flowchart of the operation, the design of a high degree of process architecture and interface problems encountered and solutions are discussed in detail, as well as some development process errors encountered examples. The music player is set to play, pause, stop, previous one, the next song, lyrics display and other functions in one, good performance, cool player interface. Android mobile phone system can run independently. The player also has access to the phone file browser function, song playback mode (single cycle, single cycle, order cycle, the order of play, random play), as well as the opening and closing lyrics state humane set the music the name of the player: \
