//      final VerticalInfiniteCycleViewPager infiniteCycleViewPager =
//                (VerticalInfiniteCycleViewPager) view.findViewById(R.id.vicvp);
        final HorizontalInfiniteCycleViewPager infiniteCycleViewPager =
                (HorizontalInfiniteCycleViewPager) view.findViewById(R.id.hicvp);
        infiniteCycleViewPager.setAdapter(...);
        infiniteCycleViewPager.setScrollDuration(500);
        infiniteCycleViewPager.setInterpolator(...);
        infiniteCycleViewPager.setMediumScaled(true);
        infiniteCycleViewPager.setMaxPageScale(0.8F);
        infiniteCycleViewPager.setMinPageScale(0.5F);
        infiniteCycleViewPager.setCenterPageScaleOffset(30.0F);
        infiniteCycleViewPager.setMinPageScaleOffset(5.0F);

// false - negative
infiniteCycleViewPager.startAutoScroll(...);
infiniteCycleViewPager.stopAutoScroll();
