Setup menus for navbar

ArrayList<BottomMenu> menu = ArrayList();
menu.add(new BottomMenu(0L, getString(R.string.lbl_menu_profile), R.drawable.ic_person_grey, "a_cup_of_coffee.json"));
menu.add(new BottomMenu(1L, getString(R.string.lbl_menu_pet), R.drawable.ic_pets_grey, "a_cup_of_coffee.json"));
menu.add(new BottomMenu(2L, getString(R.string.lbl_menu_Food), R.drawable.ic_restaurant_menu_grey, null));

BottomMenu constructor parameters:

  • id: Long, id for your button
  • fragment: Fragment, fragment for this button
  • label: String, label for this button. This will be shown below button icon
  • icon: drawable res, image resource for this button
  • (optional) lottie_animation: String, a String of json file name for Lottie Animation.

Add menus to navbar

LottieBottomNavbar bottom_navbar = findViewById(R.id.bottom_navbar)
bottom_navbar.setFragmentManager(getSupportFragmentManager())
bottom_navbar.setMenu(menu)
bottom_navbar.setSelected(1)
bottom_navbar.setMenuClickListener(this)

Handle on tab clicked to change fragment

  • Implement IBottomClickListener in the activity
  • And Override menuClicked() to handle fragment transaction
@Override
    public void menuClicked(int position, long id) {
        FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
        switch (position) {
            case 1: {
                transaction.replace(R.id.fragmentContainer, profileFragment);
                break;
            }
            case 2: {
                transaction.replace(R.id.fragmentContainer, petFragment);
                break;
            }
            case 3: {
                transaction.replace(R.id.fragmentContainer, foodFragment);
                break;
            }
        }
