NestedScrollView

Kotlin |Java

open class NestedScrollView : FrameLayout, NestedScrollingParent3, NestedScrollingChild3, ScrollingView

kotlin.Any
↳	android.view.View
	↳	android.view.ViewGroup
		↳	android.widget.FrameLayout

NestedScrollView is just like android.widget.ScrollView, but it supports acting as both a nested scrolling parent and child on both new and old versions of Android. Nested scrolling is enabled by default.
