Answer 1

我遇到了同样的问题,终于找到了答案.我正在使用最新的SceneBuilder来生成FXML.完成后,我使用'View/Show Sample Controller Skeleton',它很好地列出了所需的@FXML字段和动作例程.我的ListView购买#purchaseLVClicked在Builder的代码选项卡中有一个例程设置.不幸的是,建议的处理程序例程是:

    @FXML
    void purchaseLVClicked(ActionEvent event) {
    // Do something
    }

看到问题？这不是例程的名称 - 它匹配---但是应该代替的参数 .当我解决这个问题时,问题就消失了.没有仔细检查它们,道德就不相信"建议".(MouseEvent me)(ActionEvent event)
