Init

Check out in code init:

//      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);
        infiniteCycleViewPager.setOnInfiniteCyclePageTransformListener(...);

If you want to get item position just call this method:

infiniteCycleViewPager.getRealItem();

To update your ViewPager after some adapter update or else, you can call this method:

infiniteCycleViewPager.notifyDataSetChanged();

If you want to start auto scroll or stop call this methods:

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

Other methods check out in sample.

<com.gigamole.infinitecycleviewpager.HorizontalInfiniteCycleViewPager
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:icvp_interpolator="..."
    app:icvp_center_page_scale_offset="30dp"
    app:icvp_max_page_scale="0.8"
    app:icvp_medium_scaled="true"
    app:icvp_min_page_scale="0.5"
