RecyclerView 滑动时不加载图片，空闲时恢复图片加载

 mRecycleView.addOnScrollListener(new RecyclerView.OnScrollListener() {
            @Override
            public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
                if (newState == RecyclerView.SCROLL_STATE_IDLE) {
                    if (getActivity() != null){
                        Glide.with(getActivity()).resumeRequests();//恢复Glide加载图片
                    }
                }else {
                    if (getActivity() != null){
                        Glide.with(getActivity()).pauseRequests();//禁止Glide加载图片
                    }
                }
            }
        });
