ViewPager.PageTransformer

public static interface ViewPager.PageTransformer

androidx.viewpager.widget.ViewPager.PageTransformer


A PageTransformer is invoked whenever a visible/attached page is scrolled. This offers an opportunity for the application to apply a custom transformation to the page views using animation properties.

As property animation is only supported as of Android 3.0 and forward, setting a PageTransformer on a ViewPager on earlier platform versions will be ignored.
