摘要智能手机作为智能信息化飞速发展的产物,在人们日常生活中扮演着愈加重要角色。2014年第二季度,市场分析机构Strategy Analytics 公布了智能手机操作系统全球分布情况。根据报告显示,在全球的手机系统中 Android占到84.6%的份额,并仍在上升。由此可以看出 Android 智能手机受到了广大群众的欢迎。同时,丰富多样的手机应用也为用户的生活带来了诸多便捷。2014年《中国手机 APP下载TOP100排行榜》显示,生活、工具类APP下载占比最高,其中,工具类上榜应用高达 12款。由此可见,开发一款基于 Android 平台的录音记事本软件具有很大的实用性和市场前景。 本文介绍一款基于 Android 平台的 AudioNote 录音记事本。该软件实现了记事本基本功能,如:信息记录、存储、管理功能。此外,还提供了断点录音、音频与文本同步、拍照记录等功能。在我们听讲座、会议以及课程的过程中,如何更加全面和便捷的记录内容,并高效、精确的找到重点,对用户来说及其重要。AudioNote记事本就是基于此目标进行设计的。用户在使用中单击文字,可使音频精确的跳转到相应的时间点开始播放,不仅可以全面的记录信息,并且可高效的阅览重点内容。 27574 毕业论文关键词 Android 录音记事本 同步 音频 SQLite Title The research and design of the AudioNote record record Abstract Smartphone as a product of the rapid development of intelligent information, in people's daily life plays an increasingly important role. 2014 second quarter, the market research firm Strategy Analytics released the smartphone operating system worldwide distribution. The report shows that the global market share reached 84.6 percent of Android system, and an upward trend, which can be seen the degree of popularity and the popular Android smartphones. At the same time, a variety of Android mobile applications for the user's life brought a lot of convenience. 2014 "China Mobile APP download TOP100 list" shows that life, tools APP download the highest proportion in which tools list up to 12 applications. Thus, the development of an Android-based recording Notepad software has great practical and market prospects. This article describes an Android-based platform AudioNote recordings Notepad. The software implements the notepad basic functions such as: information recording, storage and management capabilities. The software implements the notepad basic functions such as: information recording, storage and management capabilities. In addition, it also provides a breakpoint recording, audio and text sync, camera records and other functions. In the course of our lectures, conferences and courses, and how to be more comprehensive and convenient recording content, and efficient, pinpoint focus, the user is extremely important. AudioNote Notepad is designed based on this target. Users click the text in use, the audio can jump to the exact point in time to play, not only comprehensive record information and reading of the key elements efficiently.
