我希望能够在单击每个按钮时更改图像。
答案 0 :(得分:2)
fx:id=imageViewer
应更改为fx:id=imgView
作为类中的字段名称,它对于fxml中的所有fx:id
也应相同,它们应与类中的字段名称匹配
答案 1 :(得分:-1)
我的代码也不起作用。`如果(buttonText.contains(“ Raise”)){
youramountbetmoney.setText(“ raise”);
字符串图片=“ cards52(” + x +“)。jpg”;
yourcard1.setImage(new Image(FXMLDocumentController.class.getResourceAsStream(“ holdemtexas / image / cards52(1).jpg”)));;
// ImageView yourcard1 = new ImageView();
// Image image1 = new Image(FXMLDocumentController.class.getResourceAsStream(“ cards52(1).jpg”)));
//yourcard1.setImage(image1);
}
`
