resolved:

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);
