Java “有麻烦”；“如何创建底部导航”；胶子（createButton）

我正在尝试为我的Gluon移动应用程序添加底部导航，所以我四处寻找，发现了以下内容：。我试图在我的代码中实现它，但它不起作用，所以我将它转移到一个空的、单视图的项目中。在那里，经过一些故障排除和导入包之后，我能够识别出具体的错误。如下所示（周围有两个星号的代码是产生错误的代码，以下是错误）：

每行的错误： 找不到符号 符号：方法createButton（字符串，节点，（e）->showV[…]ew2”）） 位置：bottomNavigation类型的变量bottomNavigation

以下是完整的代码：

import javafx.scene.control.Label;
import javafx.scene.control.ToggleButton;
import javafx.scene.image.Image;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class MyFirstApplication extends MobileApplication {

@Override
public void init() {

    addViewFactory(HOME_VIEW, () ->
    {

        StackPane root = new StackPane();
        root.getChildren().add(new Label("test"));

        View view = new View(root) {

            @Override
            protected void updateAppBar(AppBar appBar) {
                appBar.setTitleText("Home");
            }

        };
        view.setBottom(createBottomNavigation());
        return view;
    });

}

private BottomNavigation createBottomNavigation() {
    BottomNavigation bottomNavigation = new BottomNavigation();

    BottomNavigationButton btn1 = bottomNavigation.createButton("View1", MaterialDesignIcon.DASHBOARD.graphic(), e -> showView("view1"));
BottomNavigationButton btn2 = bottomNavigation.createButton("View2", MaterialDesignIcon.AC_UNIT.graphic(), e -> showView("view2"));
BottomNavigationButton btn3 = bottomNavigation.createButton("View3", MaterialDesignIcon.MAP.graphic(), e -> showView("view3"));


    bottomNavigation.getActionItems().addAll(btn1, btn2, btn3);

    return bottomNavigation;
}

private void showView(String viewName) {
    MobileApplication.getInstance().switchView(viewName);
}
}

您应该首先查看JavaDoc。 此方法已被弃用并随后被删除。折旧消息准确地描述了您必须使用的内容

只是重申一下，在查看文档之前，不要开始在互联网上搜索答案

最新的JavaDoc for Glisten框架（移动用户界面）是在

好的，我很抱歉。但是，我仍然不确定如何使用按钮。我确实阅读了BottomNavigationButton的文档，并尝试编写了一个示例，但我不习惯使用JavaDocs，所以我有点困惑。它还说我需要使用toggleButton，我不确定如何使用。如果有示例，请与我分享非常感谢。谢谢！
