有没有办法将参数传递给fxml文件中的onAction方法？或者,我可以以某种方式获取调用onAction方法的组件的fx：id吗？
我有几个按钮应该做同样的事情,比如5个带有ids button1的按钮 – 按钮5,当按下时,应该打印相应的数字1-5.我不希望有5个与此变量相同的onAction方法.
任何帮助,赞赏,

只调用一个处理程序,actionEvent.source是发起事件的对象.
试试这个：
myButton1.setOnAction(new MyButtonHandler());
myButton2.setOnAction(new MyButtonHandler());
private class MyButtonHandler implements EventHandler<ActionEvent>{
@Override
public void handle(ActionEvent evt) {
if (evt.getSource().equals(myButton1)) {
//do something
} else if (evt.getSource().equals(myButton2)) {
//do something
}
}
}
要么：
myButton1.addEventHandler(ActionEvent.ACTION,new MyButtonHandler());
myButton2.addEventHandler(MouseEvent.CLICKED,new MyButtonHandler());
private class MyButtonHandler implements EventHandler<Event>{
@Override
public void handle(Event evt) {
if (evt.getSource().equals(myButton1)) {
//do something
} else if (evt.getSource().equals(myButton2)) {
//do something
}
}
}
试试这个：
myButton1.setOnAction(new MyButtonHandler());
myButton2.setOnAction(new MyButtonHandler());
private class MyButtonHandler implements EventHandler<ActionEvent>{
@Override
public void handle(ActionEvent evt) {
if (evt.getSource().equals(myButton1)) {
//do something
} else if (evt.getSource().equals(myButton2)) {
//do something
}
}
}

myButton1.addEventHandler(ActionEvent.ACTION,new MyButtonHandler());
myButton2.addEventHandler(MouseEvent.CLICKED,new MyButtonHandler());

@Override
public void handle(Event evt) {
if (evt.getSource().equals(myButton1)) {
//do something
} else if (evt.getSource().equals(myButton2)) {
//do something
}
}
}
