Now you can set addOnPageChangeListener on View Pager to Observe change in Page position.

Since you wanted to setup a listener and retrieve the position when the page is switched

mViewPager.addOnPageChangeListener(object : OnPageChangeListener {
            override fun onPageScrollStateChanged(state: Int) {}
            override fun onPageScrolled(position: Int, positionOffset: Float, positionOffsetPixels: Int) {}

            override fun onPageSelected(position: Int) {
                pagePosition.setText("" + position + "/" + galleryAdapter!!.count)
            }
        })
