简要说明：应用程序将根据单词库文件中的单词向用户显示随机图像，用户将必须标识图像的名称（单个单词）。用户可以通过点击通过按钮或者识别图像来“通过”，然后“下一个”按钮将弹出将其引导到下一个图像。 在最后的图像，下一步按钮将“继续”按钮，这将导致用户对游戏的结束画面更换Speech to text result = null error
问题： 每一次，我到达了最后一张照片，并试图回答这个问题时，或者当“继续”按钮出现，我点击它也会导致游戏崩溃。 “不幸的是，石化公司停止”
错误消息指向行：
if (wordBANK.contains(result.get(0).toLowerCase()) && UnSpokenList.get(randomNum).contains(result.get(0).toLowerCase())) {
我看不出有什么问题，这条线，因为它一直在努力罚款前面的图像，直到最后图片。

任何想法？先谢谢你！
你从来没有用'randomNum =（random.nextInt（UnSpokenList第0指数结束了。 size（） - 1）+ 1）;'......是故意的吗？ – Shaishav
是的，第一个元素是“Word Bank：”，它显示微调列表的名称是有意为之。该单词不在主文件库文件中，并且不是要显示的图像。 UnSpokenList.add（0，“Word Bank：”）;它被认为是从1 - 最大尺寸 – Brandon
对于最后一张照片，因为你不需要使用randomNum，所以你忘了改变它。 –
