Android音乐播放器设计与源码

基于Android系统的音乐播放器设计与实现

摘

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效果及用户体验，因此，也逐步的提高了对系统的要求。本文主要是在Android系统上对音乐播放器应用程序的设计与实现进行讨论，通过这一过程来进一步学习与应用Android平台，这样对个人的未来发展也很有意义。

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开发工具对播放器代码进行编写。同时给出了详细的系统设计过程、部分界面截图及主要的功能流程图，本文还对开发过程中遇到的问题和解决方法进行了详细的讨论，该音乐播放器集下载、播放、暂停、停止等功能于一体，性能良好，在Android系统中能独立运行。MP3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做深究。

实验证明，基于Android平台的软件开发简单，使用方便简洁，必将成为未来几年的发展方向，具有普遍意义。

Abstract

Today's increasingly fast pace of life in society, with the hardware of mobile devices become increasingly sophisticated, people demand more and more mobile devices, high technology from the past to the present pursuit of the pursuit of visual and user experience, therefore, also gradually increased the system requirements. This article is in the Android system, music player application on the design and implementation to discuss the process through which to further study and application of Android, so the future development of personal sense.

Music player of this paper uses Android open-source system technology, the use of Java language and Eclipse development tools for the preparation of the player code. At the same time gives a detailed system design process, some interface screenshots and the major function of flow, the paper also encountered in the process of development problems and solutions were discussed in detail, the music player, set download,play, pause, stop and other functions, good performance, in the Android system can run independently. MP3 is a compressed audio file format, as the player is limited to the application layer of the program, so not to go into the specific compression algorithm.

Experiments show that, based on the Android platform, software development is simple, concise and easy to use, will become the development direction of the next few years, have universal significance.

Keywords： Android, music player, MP3
