Issue #5 is not fixed

Issue #5 is marked as fixed but as of Android 4.0 the behavior is back.

I have the latest version of the Wheel but running on a real device (Samsung 
Galaxy SII) with Android 4.0.4 the Wheel scrolls inside a ScrollView but it is 
VERY unresponsive. I need to make sure to click precisely in the center of the 
wheel hold my position for a moment and slowly scroll. With the same wheel 
outside of the ScrollView it functions flawlessly.

My layout:

--------------main layout
LinearLayout
 ScrollView
  LinearLayout
-----------------compound control layout
   LinearLayout
    WheelView
    WheelView
    WheelView

Not sure if it matters but the direct parent of the wheel is not the ScrollView 
so the call to getParent().requestDisallowInterceptTouchEvent(true) might not 
be working properly. The WheelView is inside a compound control and I believe 
the parent LinearLayout is being merged into the next parent so the end result 
overall is only 2 LinearLayouts not 3 (I could be mistaken about that). 

I tried to put a while loop in its place that recursively went through all 
parent checking for ScrollViews and making the appropriate call as needed but 
this didn't work either.

I found a solution to this. In WheelView.java on line 611 change the switch 
statement to the following:

switch (event.getAction()) {
    case MotionEvent.ACTION_DOWN: //added to fix problem
    case MotionEvent.ACTION_MOVE:
        if (getParent() != null) {
            getParent().requestDisallowInterceptTouchEvent(true);
    }
    break;

    case MotionEvent.ACTION_UP:
        if (getParent() != null) { //added to fix problem, this may be uneeded
            getParent().requestDisallowInterceptTouchEvent(false);
        }

    if (!isScrollingPerformed) {
        int distance = (int) event.getY() - getHeight() / 2;
        if (distance > 0) {
            distance += getItemHeight() / 2;
        } else {
                distance -= getItemHeight() / 2;
        }
        int items = distance / getItemHeight();
        if (items != 0 && isValidItemIndex(currentItem + items)) {
                notifyClickListenersAboutClick(currentItem + items);
            }
    }
    break;
}
