电子词典的实现（一）
来源：互联网 发布：宏程序编程入门讲解 编辑：程序博客网 时间：2024/05/16 01:15
一．项目功能简介
电子词典具有离线查询和在线查询两种功能，离线查询不用联网就可以查询到单词的释义，不过，只能查询本数据库中的一些单词，查询不到的单词是因为本数据库中没有，所以这一缺点还有待改进；如果想查询离线查不到的单词，可使用在线查询，词典会调用有道词典在线解答，会有更多的释义。此APP还有很多不足之处，还有待改进。
词典数据保存在小型数据库sqlite中，在res的raw文件夹下。
二.运行效果图
APPt图标 APP引导界面 离线 查询界面
查询结果以对话框的形式显示 生词本界面通过listvtew展示 在线查询界面
在线查询调用有道词典界面
三 ．项目源码
