public static void setSupportsChangeAnimations(ViewPager2 viewPager, boolean enable) {

for (int i =0; i < viewPager.getChildCount(); i++) {

View view = viewPager.getChildAt(i);

        if (viewinstanceof RecyclerView) {

RecyclerView.ItemAnimatoranimator = ((RecyclerView) view).getItemAnimator();

            if (animator !=null) {

((SimpleItemAnimator) animator).setSupportsChangeAnimations(enable);

            }

break;

        }
