public View getViewByPosition(RecyclerView recyclerView, int position, int viewId) {
        if (recyclerView == null) {
            return null;
        }
        BaseViewHolder viewHolder = (BaseViewHolder) recyclerView.findViewHolderForLayoutPosition(position);
        return viewHolder.getView(viewId);
    }
get the specific view by position,e.g. getViewByPosition(2, R.id.textView)
