Class NestedScrollView

  • All Implemented Interfaces:
    android.graphics.drawable.Drawable.Callback, android.view.accessibility.AccessibilityEventSource, android.view.KeyEvent.Callback, android.view.ViewManager, android.view.ViewParent, androidx.core.view.NestedScrollingChild, androidx.core.view.NestedScrollingChild2, androidx.core.view.NestedScrollingParent, androidx.core.view.ScrollingView
    public class NestedScrollView
extends android.widget.FrameLayout
implements androidx.core.view.NestedScrollingParent, androidx.core.view.NestedScrollingChild2, androidx.core.view.ScrollingView
    NestedScrollView is just like 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.
