How to croll this... ScrollView

Question

I try to force scroll ScrollView to some point. I use Handler to ensure that data in scroll view already loaded and it is huge.

Handler handler1 = new Handler();
  handler1.postDelayed(new Runnable() {
    @Override
    public void run() {
       scrollView.smoothScrollTo(0, 1500);
    }
}, 1500);

But why any of smoothScrollTo or scrollTo do nothing?
