"How to Create Bottom Navigation" Gluon (createButton) 有问题

Question

我正在尝试向我的 Gluon Mobile 应用程序添加底部导航，所以我环顾四周发现了这个：。我试图将它实现到我的代码中，但没有用，所以我将它转移到一个空的单视图项目中。在那里，我能够在 一些故障排除和导入包后 确定特定错误。如下（带两个星号的代码是产生错误的代码，以下是错误）：

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"));

每行错误： 找不到标志 符号：方法 createButton(String,Node,(e)->showV[...]ew2")) 位置：BottomNavigation

类型的变量 bottomNavigation

完整代码如下：

package com.myfirstapplication;

import com.gluonhq.charm.glisten.application.MobileApplication;
import com.gluonhq.charm.glisten.control.AppBar;
import com.gluonhq.charm.glisten.control.BottomNavigation;
import com.gluonhq.charm.glisten.mvc.View;
import com.gluonhq.charm.glisten.visual.MaterialDesignIcon;
import com.gluonhq.charm.glisten.visual.Swatch;
import javafx.scene.Scene;
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);
}
}

您应该始终首先查看 JavaDoc。查看 CreateButton method 的文档。 此方法已弃用并随后被删除。折旧消息准确描述了您必须使用的东西。

重申一下，在查看文档之前不要开始在互联网上搜索答案。好的起点是 https://docs.gluonhq.com/ Glisten 框架（移动 UI）的最新 JavaDoc 在 https://docs.gluonhq.com/charm/javadoc/6.0.6/com.gluonhq.charm.glisten/module-summary.html
