Remove BottomNavigationView labels

Question

Google released new support library v25 with BottomNavigationView

is there any way to remove items labels ?

Answer 1

I wanted to remove both the shift animation and the labels and none of the solutions here worked well for me, so here's the one I built based on everything I learned here:

public void removeLabels(@IdRes int... menuItemIds) {
    getViewTreeObserver().addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {
        @Override public boolean onPreDraw() {
            getViewTreeObserver().removeOnPreDrawListener(this);

            // this only needs to be calculated once for an unchecked item, it'll be the same value for all items
            ViewGroup uncheckedItem = findFirstUncheckedItem(menuItemIds);
            View icon = uncheckedItem.getChildAt(0);
            int iconTopMargin = ((LayoutParams) uncheckedItem.getChildAt(0).getLayoutParams()).topMargin;
            int desiredTopMargin = (uncheckedItem.getHeight() - uncheckedItem.getChildAt(0).getHeight()) / 2;
            int itemTopPadding = desiredTopMargin - iconTopMargin;

            for (int id : menuItemIds) {
                ViewGroup item = findViewById(id);
                // remove the label
                item.removeViewAt(1);
                // and then center the icon
                item.setPadding(item.getPaddingLeft(), itemTopPadding, item.getPaddingRight(),
                        item.getPaddingBottom());
            }

            return true;
        }
    });
}

@SuppressLint("RestrictedApi")
private ViewGroup findFirstUncheckedItem(@IdRes int... menuItemIds) {
    BottomNavigationItemView item = findViewById(menuItemIds[0]);
    int i = 1;
    while (item.getItemData().isChecked()) {
        item = findViewById(menuItemIds[i++]);
    }
    return item;
}

Just add this method to your custom BottomNavigationView and call it passing the ids of the menu items.
