Is it possible to easily center the content of the view below AppBarLayout, inside CoordinatorLayout?

try custom behaviour .

class ViewBelowAppBarBehavior @JvmOverloads constructor(
        context: Context? = null, attrs: AttributeSet? = null) : CoordinatorLayout.Behavior<View>(context, attrs) {

    override fun layoutDependsOn(parent: CoordinatorLayout?, child: View?, dependency: View?) = dependency is AppBarLayout

    override fun onDependentViewChanged(parent: CoordinatorLayout?, child: View?, dependency: View?): Boolean {
        val appBar = dependency as AppBarLayout
        // т.к. y - отрицательное число
        val currentAppBarHeight = appBar.height + appBar.y 
        val parentHeight = parent?.height ?: 0
        val placeHolderHeight = (parentHeight - currentAppBarHeight).toInt()
        child?.layoutParams?.height = placeHolderHeight
        child?.requestLayout()
        return false
    }
}
