Android 膨胀第二个布局时出现问题

我正在尝试在我的活动中设置第二个充气布局，一个是充气以设置时间选择器发出的警报，另一个是充气以设置数量选择器。到目前为止，第二个按钮不会响应，或者，根据另一组代码（显示的代码），我得到一个运行时错误。谁能告诉我我做错了什么

请编辑您的代码，使其更具可读性，并且只包含相关部分。另外，我不认为你可以在活动中夸大第二个布局。是的，这有点像弗兰肯斯坦，但我还在学习。如果有什么区别的话，布局不会在一个未命中的同时膨胀，而在另一个未命中的时候膨胀？好吧，首先，你应该重新设计这个活动。在一次单击事件处理程序中包含这么多代码是不好的。这让人很难理解。其次，您得到的错误是什么？
