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)

Slow Android emulator

By User
I have a 2.67 GHz Celeron processor, 1.21 GB of RAM on a x86 Windows XP Professional machine. My understanding is that the Android emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I, if possible, fix this problem?
