I don't want to contain my menus in the xml files. I will receive the information about menu items and order from backend side. I want to create them dynamically and set into the BottomNavigationView in the onCreate() method. Can I do this?

推荐答案

默认情况下，BottomNavigationView以一个空菜单开头.您可以使用 getMenu() 方法来获取Menu实例，然后按照上面的响应添加菜单项.例如，

By default, BottomNavigationView starts with an empty menu. You can use the getMenu() method to get the Menu instance, then add menu items as in the response above. For example,

BottomNavigationView bottomNavigation = findViewById(R.id.bottom_navigation);
Menu menu = bottomNavigation.getMenu();
menu.add(Menu.NONE, MENU_ITEM_ID_ONE, Menu.NONE, getString(R.string.str_menu_one))
    .setIcon(R.drawable.ic_action_one);
