i have do like this,

    final ScrollView mScrollView = (ScrollView) findViewById(R.id.scrollview);
    layoutSponsorBax.setVisibility(View.VISIBLE);

    Timer timer = new Timer();

    TimerTask task = new TimerTask() {
        @Override
        public void run() {
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    ViewGroup relativeL = (ViewGroup) mScrollView
                            .getChildAt(mScrollView.getChildCount() - 1);
                    final int sVH = mScrollView.getBottom()
                            - mScrollView.getTop();

                    View notePad = relativeL.getChildAt(2);
                    final int svHeight = 800;
                    Log.i("svHeight", "svHeight : " + svHeight);
                    final float duration = 2000;
                    ctt = new CountDownTimer((int) duration, 1) {
                        int temp = 0;


                        public void onTick(long millisUntilFinished) {
                            try {
                                Log.i("millisUntilFinished",
                                        "millisUntilFinished : "
                                                + millisUntilFinished);
                                Log.i("Height- Temp", "Temp : " + temp);
                                mScrollView.scrollTo(0, temp);
                                temp = (int) (((svHeight) - (millisUntilFinished / duration)
                                        * (svHeight)));
                            } catch (ArithmeticException e) {
                                e.printStackTrace();
                            } catch (Exception e) {
                                e.printStackTrace();
                            }
                        }

                        public void onFinish() {
                        }
                    }.start();
                }
