北京联合大学毕业设计 I 摘要 Android 是基于 Linux 内核的操作系统,是 Google 公司在 2007 年 11月 5日公布的手机操作系统,早期由 Googl e开发, 后由开放手持设备联盟( Open Handset Alliance ) 开发。2010 年末数据显示,仅正式推出两年的操作系统 Android 已经超越称霸十年的诺基亚( Nokia ) Symbian OS 系统。可见, Android 的发展前景很好, 但是目前 androi d 手机应用软件数量较少,应用软件的需求量较大。本文主要是对 Android 系统上的一款音乐播放器应用程序的设计和实现进行讨论。本音乐播放器是利用 java 语言和 Eclipse 编写工具等针对 android 手机操作系统的手机用户开发的,其集播放、暂停、停止、上一曲、下一曲,歌词同步显示等功能于一体,性能良好,在Android 系统中独立运行。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、歌词开闭状态以及推荐好友等友好性设置。本通过本次课题研究,进一步学****和熟练 androi d 手机应用软件开发,扩展这一领域的知识。关键词: Android 操作系统音乐播放器北京联合大学毕业设计 II Abstract Android is based on inner core of the Linux operating system. The mobile phone operating system was released by Google Corporation in November 5,2007, developed by the Google developers in early periods and by Open Handset Alliance later. At the end of 2010, data show that only two years of the official launch of Android operating system has transended Nokia Symbian OS system, which is dominated in decade. Obviously, Android development is promising, but now the quantity of android mobile phone application software are few and of the demand of application software are big. The paper is mainly to discuss ona music player application design and plishment in the Android system. The music player is written by using java language and the Eclipse tools, for the development of android mobile operating system of mobile phone users. The function is: play, pause, stop, previous song, next song, the lyrics display function, good performance , and it can operate independently in the Android system. The player has access to the file browser on the mobile phone, songs play pattern, the lyrics open and close, and mended friends settings. Through this research, further study and skilled development of android mobile application software, expansion of knowledge in this field.
