        linearLayoutManager = new LinearLayoutManager(ContextHolder.getContext());
        linearLayoutManager.setStackFromEnd(true);
        recyclerView.setLayoutManager(linearLayoutManager);
        recyclerView.scrollToPosition(adapter.getItemCount() - 1);
			
			

调用下面函数

			
recyclerView.smoothScrollToPosition(adapter.getItemCount() - 1);			
			
			

其他用法

			
//                        linearLayoutManager.scrollToPositionWithOffset(adapter.getItemCount() - 1, Integer.MIN_VALUE);
//                        linearLayoutManager.scrollToPosition(adapter.getItemCount() - 1);
