====================效果一，修改getChildDrawingOrder方法=================================

// 重载视图显示顺序让左到中间显示，再到右到中间显示
protected int getChildDrawingOrder(int childCount, int i)
{
    // long t = getSelectedItemId();
    // int h = getSelectedItemPosition();
    // if (i < childCount / 2)
    // {
    // return i;
    // }
    // return childCount - i - 1 + childCount / 2;
                                                                                                                                                                        
    // Reset the last position variable everytime we are starting a new
    // drawing loop
    if (i == 0)
        lastPosition = 0;
                                                                                                                                                                        
    int centerPosition = getSelectedItemPosition() - getFirstVisiblePosition();
                                                                                                                                                                        
    if (i == childCount - 1)
    {
        return centerPosition;
    }
    else if (i >= centerPosition)
    {
        lastPosition++;
        return childCount - lastPosition;
    }
    else
    {
        return i;
