FlowLayoutManager数据不满屏的暂时解决办法

@OverRide
public int scrollVerticallyBy(int dy, RecyclerView.Recycler recycler, RecyclerView.State state)
{
//位移0、没有子View 当然不移动
if (dy == 0 || getChildCount() == 0)
{
return 0;
}
//以下是边界判断
if (getItemCount() == getChildCount()
&& getDecoratedTop(getChildAt(0)) >= 0
&& (getHeight() - getPaddingBottom()) >= getDecoratedBottom(getChildAt(getChildCount() - 1)))
{
return 0;
}
//.....//
