RecycleView界面崩溃

Question

我正在做我的项目，当引用/子项的值在RecycleView和CardView中更改时，我需要从FIREBASE中获取数据。我的编码没有错误，但是当我尝试进入该界面时，它崩溃了。如果大家都知道请告诉我什么问题，我将在下面附上我的代码。非常感谢。

MainAlarm.java

//Perform logout action
        var buttonLogout = wait.Until(SeleniumExtras.WaitHelpers.ExpectedConditions.ElementIsVisible(By.XPath(".//div[@class='menu']/div/ul[@class='list']/li[last()]/a")));
        executor.ExecuteScript("arguments[0].click();", buttonLogout);

        //Locate confirm button in modal window
        var buttonConfirm = wait.Until(SeleniumExtras.WaitHelpers.ExpectedConditions.ElementIsVisible(By.XPath(".//button[@class='swal-button swal-button--confirm']")));
        executor.ExecuteScript("arguments[0].click();", buttonConfirm);
