与服务警报对话框警报管理

Question

IM开发1个应用中，我使用报警管理器显示我的代码below.actually问题是，存储在SQLite数据库（任务，日期和时间为1级的任务，即时通讯成功创建警报由用户设定），但我不是设置多个报警在此。而我的下一个问题是，我想显示警报对话框时，报警器已通过服务 .IM已经在时间运用音乐和振动解雇警报被解雇，并且也会生成通知，但问题在于锄头在我的服务中停止播放音乐。

一般我的问题

是

我想停止对notificatoin音乐已经被用户cancled，到那时，我想播放音乐。 我想设置警报对话框，当发出警报时

thanx提前...任何建议是欣赏..！ 我的代码显示如下..

如果你的音乐是在服务使用stopSelf();或使用

if(music.isPlaying()){ 
music.stop(); 
music.release(); 
} 

这应该停止播放音乐。
