Can not use gravity offset with center gravity properties

[luongvo]

When I using this lib to make badge numbers with https://github.com/ittianyu/BottomNavigationViewEx. I write the code as below to bind the badge view into the navigation item view:

badges.add(new QBadgeView(this)
                .bindTarget(binding.bnvHome.getBottomNavigationItemView(position))
                .setBadgeGravity(Gravity.CENTER)
                .setGravityOffset(8, -6, true)
                .setBadgePadding(0, true)
                .setBadgeTextSize(7, true)
                .setBadgeBackgroundColor(ContextCompat.getColor(this, R.color.badge))
                .setBadgeTextColor(ContextCompat.getColor(this, R.color.badge))
                .stroke(ContextCompat.getColor(this, R.color.badge_text), 2, true)
                .setShowShadow(false));

The problem is I can not use gravity offset with center gravity to display a badge number relative to the navigation icon, instead relative to navigation view frame layout.
