How to create Bottom Navigation

Question

I am new to mobile development, I started using Gluon mobile for Netbeans and I'm trying to add a Bottom navigation bar to the default Gluon Mobile App. They describe the class in the JavaDoc http://docs.gluonhq.com/charm/javadoc/4.1.0/com/gluonhq/charm/glisten/control/BottomNavigation.html but I can't seem to make it work. Would someone be able to post a snippet on how and where to do this?

Answer 1

Here is a simple example:

public class GluonApplication 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();

    ToggleButton btn1 = bottomNavigation.createButton("View1", MaterialDesignIcon.DASHBOARD.graphic(), e -> showView("view1"));
    ToggleButton btn2 = bottomNavigation.createButton("View2", MaterialDesignIcon.AC_UNIT.graphic(), e -> showView("view2"));
    ToggleButton 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);
}

}
