这是任玉刚android艺术探索的源码，分享给大家，方便大家学习使用，让大家共同交流，共同进步，一起努力。。。

Android 完美实现从缩略图到大图片原图无疑切换，其实这个功能是动画效果的图片缩放，将一张图片从缩略图状态显示到原图状态，原图一般都是比较的，本实例将两者之前的切换无缝衔接，两个层完美切换。 　　在打开的示例中，轻触图片缩略图后，图片在屏幕上逐渐被放大显示，就好比现在很多手机图库里的查看方式那样，很自然。

说明：  smack是一套很好的开源即时通讯api,是基于Xmpp协议的实现，而在Android,则提供了一个asmack的jar包，其功能以及用法跟smack一致。(Smack is a good open source instant messaging api, based on the implementation of Xmpp protocol, while Android provides an asmack jar package, which functions and uses the same as smack.)

android英语字典是手机中经常使用的应用。因此，在本文将结合Android来讨论如何实现一个Android版的英文词典。实现英文词典的方法很多。在本文使用了SQLite数据库来保存英文单词信息。系统通过SQLite数据库中保存的单词信息来查找到与指定英文对应的中文信息。(Android Dictionary of English is often used in mobile phone applications. Therefore, in this paper will be combined with Android to discuss how to implement a Android version of the English dictionary. A lot of ways to realize the English dictionary. In this paper, we use the SQLite to save the English word information. The system through the SQLite to save the word information to find the corresponding Chinese information with the specified english.)
