Get the new position while scrolling

[drhootch]

Great library guys, only it lacks the possibility to get the new position while being scrolled. setOnWheelChangeListener is not enough, for it triggers only when switching between states. A useful listener would be a ChangingListener with onChanged method:

public interface OnWheelChangeListener {
    public void onChanged(View wheel, int oldPosition, int newPosition) ;
}

Hello again, i came back to this library after a while and i see that setOnWheelChangeListener now contains three methods: onWheelScrollStateChanged(int state), onWheelSelected(int position) and finally the one i'm interested wit : onWheelScrolled(int offset), but still not enough; the offset parameter alone is practically useless, however i was able to add this lines to the library:

//changed the OnWheelChangeListener interface to look like this:
void onWheelScrolled(int offset, int position)

//and in the WheelPicker.java added this lines to onDraw method:
protected void onDraw(Canvas canvas) {
//get the position using the new mScrollOffsetY
        int position = (-mScrollOffsetY / mItemHeight + mSelectedItemPosition) % mData.size();
        position = position < 0 ? position + mData.size() : position;

//call the onWheelScrolled with both mScrollOffsetY for offset, and the new position
        if (null != mOnWheelChangeListener)
            mOnWheelChangeListener.onWheelScrolled(mScrollOffsetY, position);
.
.
.
}

Can you please add this to the library? @AigeStudio Thank you.

I think this might solve an issue I'm having where you can tap the scroll wheel while its in the middle of scrolling through a range and it gets caught in the middle between two selections. It would be nice to be able to snap to the nearest etc.
