PageTransformer
interface 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.
