Android's new Overscroll functionality introduced in Gingerbread and discovered some more interesting things. The functionality to make a a view scroll beyond its limits and then bounce back (almost exactly like iOS) is sort of built into the framework, but just hidden.

Solution

  • You can try this it give. you the solution for your problem.

    scrollView = (ScrollView) findViewById(R.id.scr);
        contentView = (ViewGroup) findViewById(R.id.r2);
        scrollView.setOnTouchListener(new ScrollPager(scrollView, contentView));
        scrollView.post(new Runnable() {
            public void run() {
                scrollView.scrollTo(0, contentView.getPaddingTop());
            }
        });
    

    for this you need the scroolerPager Class. get it here,

      public class ScrollPager implements OnTouchListener
    public ScrollPager(ScrollView aScrollView, ViewGroup aContentView)
        {
            mScrollView = aScrollView;
            mContentView = aContentView;
            scroller = new Scroller(mScrollView.getContext(), new OvershootInterpolator());
            task = new Runnable()
            {
                public void run()
                {
                    scroller.computeScrollOffset();
                    mScrollView.scrollTo(0, scroller.getCurrY());
    
                    if (!scroller.isFinished())
                    {
                        mScrollView.post(this);
                    }
                }
            };
        }
