基于Android的手机音乐播放器的设计与实现 摘 要 在我们的信息科技大时代背景下手机已经成为人们生活中的必需品，本课题是在安卓的平台下进行手机音乐播放器的设计以及实现。现在的音频格式越渐多了起来，比如我们常见的音频WMA和MP3，为了能够播放这些格式的音频可扩展性是十分重要的一个特性，Android平台是一个开放性的平台，代码是开放给大众使用的，为播放器各种功能的添加和实现提供了很大的便利，也能更好的定义手机功能。 文中会对播放器功能进行需求分析，确保用户对该播放器的理解和使用，实现播放器具有的一系列功能。具体的功能有：音乐的播放、暂停、进度条的控制、歌曲时间的显示、下一首歌曲、上一首歌曲、歌曲的循环，歌曲专辑列表，艺术家列表以及歌词的显示，主要采用了Intent来进行各个界面的切换和广播机制来控制歌曲进度以及自动检测一首歌曲完成后自动进入下一曲的播放，并且对多个按钮进行监听来同步用户对播放器的操作，歌词主要采用了画布的效果使其动态显示，最后对所做的系统进行各个功能的测试和验证。? 【关键词】 Android平台；手机音乐播放器；扩展性 The Design And Implementation Of Mobile Phone Music Player Based On Android Abstract Mobile phone has become a necessity in peoples life in the background of our information technology. This topic is the design and implementation of mobile music player on the platform of Android.Now the audio format is getting more and more, for example, our common audio WMA and MP3, in order to be able to play these formats of audio scalability is a very important feature, android platform is an open platform, the code is open to the public to use, to provide a great convenience for the player to add and achieve a variety of functions, and it also can better define the mobile phone function. In this paper, the function of the player needs analysis, to ensure that users understand and use the player, at the same time the player has to achieve a series of functions. Specific functions include: the music play, pause, the progress bar control, songs of time display,?next song, previous song, song cycles, song album list, the list of artists and display of lyrics, Mainly with the intent to each interface switching and broadcast mechanisms to control the progress of the song and automatically detect automatically the next song , after the completion of intercepting and multiple button synchronous users to the operation of the player,?the lyrics mainly adopts the canvas effect makes the dynamic display,?finally made to the system to test and validate each function.
