how to disable fling of a scrollView

I want to disable the fling gesture of a scrollview and it does not seem to be working.. I thought it would be as easy as creating a basic class that extends scrollview and @Overriding the onFling method. but eclipse is giving me an error to remove the @Override:

any ideas how to disable the fling

public class ScrollViewNoFling extends ScrollView {

    /**
     * @param context
     * @param attrs
     * @param defStyle
     */
    public ScrollViewNoFling(Context context) {

        super(context);
        // TODO Auto-generated constructor stub
    }
    public ScrollViewNoFling(Context context, AttributeSet attrs) {

        super(context, attrs);
        // TODO Auto-generated constructor stub
    }
    public ScrollViewNoFling(Context context, AttributeSet attrs, int defStyle) {

        super(context, attrs, defStyle);
        // TODO Auto-generated constructor stub
    }

   @Override
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY)
    {
        return false;
    }

}

I solved same problem with Override fling method. If you override fling method on your ScrollViewNoFling class and not call super.fling on this method, you gonna have not-fling-handled scrollView.

@Override
public void fling (int velocityY)
{
    /*Scroll view is no longer gonna handle scroll velocity.
     * super.fling(velocityY);
    */
}

In addition to using fling() instead of onFling(), you need to pay attention to your return values.

As per the documentation for onFling():

Returns

true if the event is consumed, else false

If you want to catch the event and do nothing, return true. Otherwise, the event will be passed on to some other method/class to attempt to handle it.

I think it should be fling and not onFling. Please refer to the official documentation
