摘要随着当今社会网络技术的迅猛发展，由于二维码的自动生成和扫描识别是一项比较新兴的信息保管和传达技术，所以基于Android移动设备的二维码生成和扫描技术已成为人们生活的热点并且很好地走进了日常生活中。二维码识别技术之所以使得人们的生活变得更加便捷和智能化，是因为它可以用来促进人们的商业发展，如使用二维码进行扫码支付，二维码的电子凭据。鉴于此，二维码与移动端相结合，肯定会给生命和业务发展带来不一样的体验，因此，学习移动终端和二维码技术的结合是非常有价值的。86509

系统的设计是以Android 平台为开发环境，以 Java编程语言系统的为开发语言，并借助Eclipse和jdk等开发工具完成软件的设计和实现。首先，熟悉二维码的结构以及它的组成部件和各个部件的作用，并搭建好系统开发平台，然后进行了进行系统需求分析，在了解需求分析的基础上，对系统进行了总体设计和详细设计，最后完成了本系统在Android 平台的实现以及运行测试。

系统分为为两个模块，生成二维码系统模块和扫描二维码系统模块。在生成系统模块，在文本框中输入联系人信息，文本信息或者网址信息，点击生成按钮就会地生成相应信息的二维码图片，这时如果想要将该二维码图片保存在手机本地，可点击保存按钮就会把这个二维码图片保存下来到手机本地；在扫描模块，打开系统主界面，首先点击扫描按钮，这时需要调用手机摄像头进行拍照预览，也可以点击打开按钮，就会打开之前保存到本地的二维码图片，图像采取完成后，将进入图像处理分析，最后通过译码还原出二维码所隐藏的信息。如果显示的信息是网址信息，可以点击跳转到webview按钮,这时系统就会调用手机浏览器进行网站跳转。测试结果表明，系统实现了二维码的生成和扫描功能。

Abstract With the rapid development of technology in today's society, since the automatic generation and two-dimensional code scanning recognition is a relatively new information storage and conveying technology, based on the two-dimensional code technology Android mobile devices have become the focus of people's lives and well into our daily lives。 The reason why two-dimensional code recognition technology makes people's lives more convenient and intelligent is it can be used to promote the business development, such as the use of two-dimensional code scan code payments, electronic credentials。 In view of this, the mobile terminal of the two-dimensional code combination will certainly bring a different life experience and business development, therefore, the mobile terminal learning and implement the QR code technology on our lives are very valuable。

Design of the system under Android platform to build environmental conditions to the development of language, with Eclipse, jdk other development platform for software design of the Java programming language。Before doing software design, we need to learn the structure of QR code, familiar with its components,while the system also need to build a good development platform。 System mainly consists two modules, two-dimensional code generation system design and Recognition System。 Overall system first needs analysis, in the understanding of the needs analysis, based on the analysis of the overall design and detailed design of the system, and finally the implementation of the system and run the tests。

System is pided into two modules, system modules generate two-dimensional code and two-dimensional code scanning system modules。 Generating system modules in the text box, enter the contact information, text messages, or URL information, click the Generate button will accordingly generate two-dimensional code image information, then if you want to save the two-dimensional code image in the local phone , you can click the save button will save the two-dimensional code image down to the local phone; in the scanning module, open the system main interface, first click on the scan button, then you need to call a mobile phone camera to take pictures preview, you can click the open button, will open the previously saved to the local two-dimensional code image, the image taken after completion, will enter the image processing and analysis, and finally restore the two-dimensional code by decoding the hidden message, if the display information is the URL, you can click to jump to webview button, then call the phone browser will jump site。 The test results show that the system implements the generation and two-dimensional code scanning capabilities。generation and scanning functions; and finally software a systematic test of your system test run。
