我在如何使这个功能上遇到问题。我现在为这个布局测试了很多代码，但它不会工作。这是我制作的布局：

看起来像这样：
目标名称:(已提供数据）
开始日期:(已提供数据）
结束日期:(已提供数据）
通知选项
时间： showTime [设置] - ＆gt;时间选择器弹出
重复： showRepeat [切换按钮] - ＆gt;选择是否重复一次通知
重复选项： [设置] - ＆gt;弹出选项和选项的警报对话框是在showRepeat TextView
中打印的声音： [切换按钮] - ＆gt;选择通过声音通知

我的问题是当用户完成设置通知时，我无法使其正常工作。通知将根据他/她的选择而有效。我似乎无法找到任何我能够轻易理解的来源。
