need help for ParallaxScollListView to apply decor view

[deepikamandapalli]

Am using ParallaxScollListView as parent view and inside many views are rendering based on index position.
index 0> images
index 1> Viewpager
index 2 > viewpager
index 3> recyclerview with NestedScrollView as parent.

finally i need to apply Decor view at bottom of screen or end of recycler view ending. need offset value whether how much user has dragged & has to pull up easily.

i have applied like 3 ways , but no use.

IOverScrollDecor decor = OverScrollDecoratorHelper.setUpOverScroll(recyclerView, OverScrollDecoratorHelper.ORIENTATION_VERTICAL); - tried adding for recyclerview , not helped

final IOverScrollDecor decor = new VerticalOverScrollBounceEffectDecorator(new NestedScrollViewOverScrollDecorAdapter(nestedScrollView )); - tried adding for NestedScrollView

final IOverScrollDecor decor = OverScrollDecoratorHelper.setUpOverScroll(mParallaxScollListView); - tried adding for parallaxScrollView

Any help please...

it worked by removing the NestedScrollView from index3 > of recyclerview

and added like
final IOverScrollDecor decor = new VerticalOverScrollBounceEffectDecorator(new NestedScrollViewOverScrollDecorAdapter(parallaxScrollView));

worked!!
