You cant use like viewPager.addOnAdapterChangeListener( new TabLayout.TabLayoutOnPageChangeListener(tabLayout)); Because addOnAdapterChangeListener() method expect OnAdapterChangeListener as paramenter. You should use void addOnPageChangeListener (ViewPager.OnPageChangeListener listener) on viewPager instead.It has several callback method, So you can detect the event when page of viewPager is changed.
