scrollTo, scrollBy, smoothScrollTo, smoothScrollTo don't work.

solved:

LinearLayout ll = (LinearLayout) findViewById(R.id.ll);

        final HorizontalScrollView hsv = (HorizontalScrollView) findViewById(R.id.hsv);
        OnGlobalLayoutListener listener = new OnGlobalLayoutListener() {

            @Override
            public void onGlobalLayout() {
                hsv.scrollTo(100, 0);
            }
        };
        ll.getViewTreeObserver().addOnGlobalLayoutListener(listener);
