ABSTRACT
摘 要
在今天的市场经济下,为了满足用户的各种需求,行业及服务越来越细分化。
同样,在 Android 平台下,手机音乐播放器的用户使用习惯并不完全相同,针对
用户不同的应用需求,应该开发出不同的应用。
对比分析了现有手机音乐播放器,确定了功能简单实用、界面简洁的应用需
求。本应用实现了播放上下首歌曲、暂停、播放、拖动进度条、滑动菜单栏、对
话框以及其它功能。本应用主要实现四个界面,分别为列表界面、底边控制栏界
面、侧边菜单栏界面、播放界面。
本文在对比分析了现有的各种开发语言和平台后,决定采用 Java、XML 等语
言和 Android 平台进行开发该款应用。在开发过程中,使用到 Android 的四大组
件和 Intent,ContentProvider 等等技术。
在本文中,首先对比现有的音乐播放器,然后得出本应用研究的背景和意义。
然后对应用的需求分析、设计实现、测试、结论等方面进行论述。
关键词: 音乐播放器 系统 安卓 Java

ABSTRACT
ABSTRACT
In today's market economy, in order to meet the various needs of users, industries
and service more and more segmented. Similarly, in the Android platform, mobile music
player user habits are not the same for users of different application requirements,
should develop different applications.
Comparative analysis of the current mobile music,identified simple and practical
functions ,succinct interface’s requirement. This application implements the up and
down play songs, pause, play, drag the progress bar, slide menu, dialog box, and other
functions. Four interfaces are implemented, namely list interface, the bottom control
interface, the side menu interface, player interface.
Based on the comparative analysis of the existing range of development languages
and platforms, we decided to use Java, XML and other languages and Android platform
to develop an app. During development, use four Android components and Intent,
ContentProvider and other technologies.
In this article, the first contrast existing music player, then draw the background
and significance of this applied research. Then focusing on the needs analysis, design,
implementation, testing, and other aspects of the conclusions discussed.
Keywords: Music Player System Android Java
