RecyclerView下拉刷新时快速上拉崩溃

Question

下拉用的SwipeRefreshLayout

  mSwipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipeRefreshLayout);
        mSwipeRefreshLayout.setColorSchemeResources(android.R.color.holo_blue_bright,
                android.R.color.holo_green_light,
                android.R.color.holo_orange_light,
                android.R.color.holo_red_light);

        adapter = new DangJianRecyclerViewAdapter(this,list);

         manager = new LinearLayoutManager(this,LinearLayoutManager.VERTICAL,false);
        mRecyclerView.setLayoutManager(manager);
        mRecyclerView.setItemAnimator(new DefaultItemAnimator());

        mRecyclerView.setAdapter(adapter);

        mSwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                list.clear();
                pageIndex = 1;
                loadData(pageIndex+"");
            }
        });

        mRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
            @Override
            public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
                super.onScrollStateChanged(recyclerView, newState);
                if(newState == RecyclerView.SCROLL_STATE_IDLE){
                    int lastVisiblePosition = manager.findLastVisibleItemPosition();
                    if(lastVisiblePosition >= manager.getItemCount() - 1){
                        pageIndex +=1;

                        loadData(pageIndex+"");
                    }
                }
            }
        });

正常速度上拉下拉没什么问题，但是下拉时迅速上拉就会报错
