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.

And XML init:

<!--<com.gigamole.infinitecycleviewpager.VerticalInfiniteCycleViewPager--> <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"
  app:icvp_min_page_scale_offset="5dp"
