RecyclerView 自动滚动到最后的最简单办法

@Override
public void getDataListSucc(List dataList) {
    mAdapter.getList().addAll(dataList);
    mAdapter.notifyDataSetChanged();
    getHandler().postDelayed(() -> {
        mLinearLayoutManager.setStackFromEnd(
            mLinearLayoutManager.findLastVisibleItemPosition() - mLinearLayoutManager.findFirstVisibleItemPosition()
            < mAdapter.getItemCount() -1
        );
    },50);
}
