Vertical movements are not consumed about android-viewflow HOT 3 OPEN

Theoretically, I guess you could extend ScrollView and make sure vertical movements are consumed first when you hit a certain threshold value. It has been suggested that android-viewflow provides such wrapper class but unfortunately it doesn't yet.

I think extending ScrollView is not something I want to do. I don't need it to use a standard android gallery inside a scrollview. I had a look at the Gallery source code and I found the following in the onScroll method of the gallery widget:

    /*
     * Now's a good time to tell our parent to stop intercepting our events!
     * The user has moved more than the slop amount, since GestureDetector
     * ensures this before calling this method. Also, if a parent is more
     * interested in this touch's events than we are, it would have
     * intercepted them by now (for example, we can assume when a Gallery is
     * in the ListView, a vertical scroll would not end up in this method
     * since a ListView would have intercepted it by now).
     */
    mParent.requestDisallowInterceptTouchEvent(true);

I think this line prevents the scrollview from reacting on vertical touch events once the scroll has started. I looked through your code but I couldn't find a good spot to insert this line and test if it works. I would like to improve your gallery to incorporate this feature but I couldn't come up with a good way to retrieve the parent view and I didn't know when a scroll starts and when one scroll ends.

Could you pull the intercepttouch branch and try it out? Not sure I did it right, but requestDisallowInterceptTouchEvent seems like a good solution.
