NestedScrollView's smoothScrollTo() behaves weird

Question

What I am trying to achieve is to scroll to scroll_position_1 when tab1 (and so on) is clicked like this. I don\'t understand what\'s happening at

Answer 1

Looks like there is a bug when programmatically scrolling NestedScrollView within CoordinatorLayout. This solved my problem:

private void scrollToView(final View view) {
    mScroller.scrollBy(0, 1);
    mScroller.smoothScrollTo(0, view.getTop());
}

or for better control:

private void scrollToView(final View view) {
    mScroller.scrollBy(0, 1);
    ObjectAnimator.ofInt(mScroller, "scrollY",  view.getTop()).setDuration(700).start();
}
