how to use overscroll functionality for listview?

问题:

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.

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);
                }
            }
        };
    }

According to the android developers visit the following link. http://developer.android.com/reference/android/widget/AbsListView.html#setOverScrollMode(int)

the doc says you have to use following method.

public void setOverScrollMode (int mode)
