Answer 1

终于我找到了!根视图持有者项的布局参数是GridLayoutManager.LayoutParams并且具有getSpanIndex()方法.

RecyclerView.ViewHolder viewHolder = m_RecyclerView.findViewHolderForAdapterPosition(position);
if (viewHolder != null) {
    GridLayoutManager.LayoutParams lp = (GridLayoutManager.LayoutParams) viewHolder.itemView.getLayoutParams();
    int spanIndex = lp.getSpanIndex();
}
