//      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);
