MarginPageTransformer


public final class MarginPageTransformer implements ViewPager2.PageTransformer


Adds space between pages via the ViewPager2.PageTransformer API.

Internally relies on setTranslationX and setTranslationY.

Note: translations on pages are not reset when this adapter is changed for another one, so you might want to set them manually to 0 when dynamically switching to another transformer, or when switching ViewPager2 orientation.
