我的数组包含的元素多于此处发布的元素。我只显示2个帖子，但是有10个showGreen变量，10个其他线程，10个“ TextViews”和10个isGreenBackgroundShouldAppear函数。如您所见，当答案正确时，TextView1或TextView2在ACTION_DOWN上变为绿色，并在image_view中设置随机图像，从而准备下一个问题。问题是，如果我使用10个线程分别每500ms为每个TextView设置答案的值，那么如果用户过快按下正确答案TextView，它将被视为错误答案（红色）。如果我将500ms设置为300ms或更短，有时showGreen永远不会正确更新。您可能知道我的问题的解决方案吗？
