音乐播放器软件设计报告

音乐播放器软件设计报告

数据库设计：

歌曲类型表：类型编号、类型名称

歌曲信息表：歌曲编号、歌曲名、歌手、文件位置、类型编号

播放器界面：

（一）主界面

（三）添加歌曲界面

（五）界面变换

功能描述：

1.播放：单击播放列表中的歌曲进行播放，在播放的时候也可以选择播放的模式（顺序

播放、随机播放、单曲播放）同时界面还将显示【当前歌曲信息】歌曲名、歌

手、专辑。

2. 停止：在歌曲列表上方有个小按钮，在歌曲正在播放时，显示的是可停止的按钮，点击则可停止当前播放的歌曲。

3.换歌：在歌曲列表上方有个小按钮，当歌曲正在播放时，可以进行前一曲后一曲的变

换。

4.搜歌词歌曲：在侧界面中有【搜歌词】，选择此项，然后选择歌词服务器联网的方式，并

添加【歌手名】【歌曲名】（二者至少选择一项）即可继续搜索歌词歌曲

5 添加歌曲：在播放列表的下方，有【添加】按钮，点击后即可选择想要添加歌曲

6. 删除歌曲：在播放列表的下方，有【删除】按钮，选择要删除的歌曲，点击【删除】即

可正确的删除歌曲

7 换肤：点击换肤，则会弹出一个小框，在此可以进行界面变换

注：在搜索歌词的时候，歌曲服务器类型不能为空，否则将无法进行搜索

代码解析

1.主界面可进行的各项操作：ListView

2.添加歌词歌曲信息：WinControl

3.播放音乐时可进行的各项操作（如搜索歌词）：MainDlg

在此主要写了音乐播放器所能进行的主要操作的代码解析，其余类函数及其方法的作用见源代码中的注释
