Kotlin |Java

public final class BandPredicate.NonDraggableArea extends BandPredicate

java.lang.Object
↳	androidx.recyclerview.selection.BandPredicate
	↳	androidx.recyclerview.selection.BandPredicate.NonDraggableArea

A BandPredicate that allows initiation of band selection in any area that is not draggable as determined by consulting inDragRegion. By default empty areas (those with a position that maps to NO_POSITION are considered non-draggable.

Use this implementation in order to permit band selection in otherwise empty areas of a View. This is useful especially in list layouts where there is no empty space surrounding the list items, and individual list items may contain extra white space (like in a list of varying length words).
