Java onClickListener正在崩溃应用程序，onOptionsItemSelected未按预期触发

我正在尝试创建一个带有嵌入式数据库的基本评级应用程序。但不幸的是，每当我试图为reportSomeoneButton编写onClickListener时，应用程序就会崩溃，或者事件没有被正确调用，而按钮什么也不做

预期的操作是，让某人单击ReportSomeOne按钮，这将创建一个警报对话框，请求用户输入。用户输入注释，然后信息存储在数据库中并填充下表

我已经为此挣扎了好几个小时了。教程并没有提到我要找的东西，关于stackoverflow的其他问题对学习不同的东西很有帮助，但我似乎无法理解这一点。我对Android Studio的开发非常陌生，所以任何形式的帮助都将不胜感激，无论是一个完美的解决方案还是为我的研究指明正确的方向，都将不胜感激

不管怎么说，我的情况如下：
