Remove BottomNavigationView labels

Would you want to this style ?

If so, I recommend you try BottomNavigationViewEx.

I hope I am not too late to the party here.

But as of Design Support Library 28.0.0-alpha1 you can use the property

app:labelVisibilityMode="unlabeled"

you can use other values "auto", "labeled" and "selected" as well.
