英文:
ToggleGroup to toggle between male and female java
问题
我正在尝试创建一个切换按钮，用于更改所选的性别，我试图让它在男性和女性之间切换，但是当我运行它并选择一个组时，它既不选择男性也不选择女性。
ToggleGroup genderToggle = new ToggleGroup();
maleButton.setToggleGroup(genderToggle);
maleButton.setUserData("male");
femaleButton.setToggleGroup(genderToggle);
femaleButton.setUserData("female");
submitButton.setOnAction(new ButtonListener());
genderToggle.selectedToggleProperty().addListener(new ChangeListener<Toggle>()
{
public void changed(ObservableValue<? extends Toggle> ob, Toggle o, Toggle n)
{
RadioButton rb = (RadioButton)genderToggle.getSelectedToggle();
if (rb.getUserData().equals("male"))
{
maleButton.setSelected(true);
femaleButton.setSelected(false);
}
else if (rb.getUserData().equals("female"))
{
maleButton.setSelected(false);
femaleButton.setSelected(true);
}
else
{
maleButton.setSelected(false);
femaleButton.setSelected(false);
}
}
});

ToggleGroup genderToggle = new ToggleGroup();

maleButton.setUserData("male");
femaleButton.setToggleGroup(genderToggle);
femaleButton.setUserData("female");

我认为问题出在您在切换对象上使用了.equals(...)，而应该首先获取用户数据字段，因为这是您设置为性别字符串的字段。例如：
if (genderToggle.getUserData().equals("female"))
{
maleButton.setSelected(false);
femaleButton.setSelected(true);
}
英文:
I think the issue is that you are using .equals(...) on the toggle object, instead first get the user data field, as this is the one you set to the gender string. E.g.:
if (genderToggle.getUserData().equals("female"))
{
maleButton.setSelected(false);
femaleButton.setSelected(true);
}
