You can also use ViewPager.SimpleOnPageChangeListener instead of ViewPager.OnPageChangeListener and override only those methods you want to use.

viewPager.addOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {

    // optional 
    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { }

    // optional 
    @Override
    public void onPageSelected(int position) { }

    // optional 
    @Override
    public void onPageScrollStateChanged(int state) { }
});

Hope this help :)

Edit: As per android APIs, setOnPageChangeListener (ViewPager.OnPageChangeListener listener) is deprecated. Please check this url:- Android ViewPager API
