java问答应用程序在最后一个问题中未显示对话框

Question

因此，当在测验中问最后一个问题时，如果正确与否，它不会显示对话框。在结果屏幕上，最后一个问题始终被认为是“正确的”

编辑：发布完整代码。我试着再次理解它，但我不知道该怎么做，这可能是我唯一剩下的问题，除了插入图像（这是另一个问题，现在我想完成这个）

编辑：我试着像这样修复if语句：

      if (button.getText().equals(currentQuestion.getAnswer())) {
            correctDialog();
        } else {
            incorrectDialog();
            coinValue--;

        }




        if (qid < list.size() - 1) {

            disableButton();


        } else

            {

            gameWon();
        }

它现在可以工作了，最后一个答案现在也可以注册，如果正确或错误，但是对话框会闪烁一秒钟并自动转到结果屏幕
