我对JavaFX和检查图形的能力有疑问。因此在我的程序中，当用户单击按钮时，我为其按钮设置了图形。
我需要找出的是在“ temp.getText（）。equals（” O“）”和“ temp.getText（）。equals（” X“）”中必须包含的内容它在检查按钮的图像名称而不是查找文本。
我想让游戏说“ X.jpg”（反之亦然）是否在按钮内，然后调用此错误屏幕弹出窗口

据我所知，您不想将文本设置为按钮，而是要根据其具有的图形（X或O）检查按钮是什么。
如果这是问题，我建议您根据所持图像/图形的类型来设置/更新按钮的属性，例如
button.getProperties().put("TYPE","X"); // For X button
button.getProperties().put("TYPE","O"); // For O button
您可以直接检查类型，而不用访问图形。喜欢..
if(space1.getProperties().get("TYPE").equals("X") && space2.getProperties().get("TYPE").equals("X") && ...){
...
}
或者，您可以利用Node的setUserData（）方法，该方法仅在内部使用上述逻辑。如果与userData一起使用，您的代码也将不再那么冗长。
button.setUserData("X");
if(space1.getUserData().equals("X") && space2.getUserData().equals("X") && ...){
...
}

无法将文件名信息保留在'/opt/cloudera/parcels/CDH-6.0.1-1.cdh6.0.1.p0.590678/lib/hadoop-0.20-mapreduce/sbin/Linux/task-controller'或ImageView中。当然，您始终可以从这两个类中的任意一个扩展并将文件名存储为字段，但是您可能不需要它。
您还可以保留两个Image实例的引用，并检查引用。
Image这里最有趣的是，您要做的只是检查“平铺”是否已填充。实际上，最简单的方法是进行Image imageX = new Image(getClass().getResource("X.jpg").toString());
Image imageO = new Image(getClass().getResource("O.png").toString());
public void playTile(ActionEvent e)
{
// Other stuff
Image currentImage = tempImageView.getImage();
if (currentImage == imageX || currentImage == imageO) // Checking for reference
{
// Your logic
}
else
{
// Your logic
}
}
。
