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.)
