基于Android系统的多媒体播放器的开发
——功能实现

摘要
在这个经济飞速发展的时代,移动设备也日益完善,我们大家都已经有了在手机上听音乐看电影的习惯,在中国大陆,谷歌发布的Android手机因其手机系统的优越性,得以迅速推广,随着Android智能手机的普及,各种基于Android的应用软件也如雨后春笋般出现了。本文主要是对Android系统上的一款多媒体播放器应用程序的设计与实现进行阐述。Android是一个开源的系统,它的底层是基于Linux操作系统的,本论文的多媒体播放器采用了Android开源系统技术,利用Java语言和Eclipse开发工具来实现这款播放器。同时给出了详细的系统设计设计过程、部分界面截图以及主要功能运行流程图,文中还对开发过程中遇到的问题及解决方案进行了讨论。该多媒体播放器集音频、视频播放于一体,音频播放部分实现了播放、暂停、上一首、下一首、音量调节、歌词同步显示、播放模式选择等功能。性能良好,用户交互友好,在Android系统中能独立运行;视频播放部分实现了一般控制功能以外,还支持不同视频画面比例的切换等功能。针对Android应用程序的开发,是适应时代要求的,对比时下硬件的发展速度,应用软件的研发还有很长的路要走。

Abstract
In this economic rapid development of The Times, mobile equipment is increasingly perfect, we all have to listen to music on their movie habit, in mainland China, Google's Android mobile phones released because of its mobile phone system, the superiority of the rapid promotion, along with Android smartphone popularization, based on the application of various Android software as have sprung up. This paper is mainly to the Android system on a multimedia player application design and implementation in this paper. Android is an open source system, which is based on the bottom of the Linux operating system, this paper used the media player the Android open source system technology, use Java language and Eclipse development tool to achieve this type of player. And presents the detailed design of the system design process, part of the interface screenshots and main function operation flow diagram, the paper also to development in the process of problems and solutions are discussed. The multimedia player set audio, video broadcast at anic whole, audio part realize the play, pause, up, down, the sound volume, lyrics synchronous display and play mode selection etc. Function. Performance is good, the user interaction friendly, in the Android system can operate independently; Video broadcast realized the general control function of outside, also support the different video images of th
