关于RecyclerAdapter的setListener方法可能有错

[l0n9er]

              if (mOnItemClickListener != null) {
                    int position = getPosition(viewHolder);
                    mOnItemClickListener.onItemClick(parent, v, mDatas.get(position), position);
                }
`

position是从0开始， int position = getPosition(viewHolder);应该要减一 否则会报IndexOutOfBoundsException越界错误
