我需要将2个单选按钮组成一组，然后检索所选按钮的值。
最佳答案
只需使用ToggleGroup
RadioButton radioButton1 = ...
RadioButton radioButton2 = ...
// TODO: add RadioButtons to scene
ToggleGroup toggleGroup = new ToggleGroup();
radioButton1.setToggleGroup(toggleGroup);
radioButton2.setToggleGroup(toggleGroup);
// listen to changes in selected toggle
toggleGroup.selectedToggleProperty().addListener((observable, oldVal, newVal) -> System.out.println(newVal + " was selected"));
您还可以使用以下方法从
ToggleGroup中检索选定的单选按钮:toggleGroup.getSelectedToggle()
万一你想从一个提交按钮或类似的东西的处理程序做到这一点...
