Android SwipeRefreshLayout 、RecyclerView冲突下拉冲突的解决方案

SwipeRefreshLayout和RecyclerView一起使用的时候，有时出现RecyclerView没有滑动到顶部，手指向下滑动时，触发了SwipeRefreshLayout的刷新事件，造成了冲突。

首先来看一个http://blog.csdn.net/zhangweiwtmdbf/article/details/41206369博客分享的一个解决方法，如下：

mLayoutManager = new LinearLayoutManager(getActivity());
			//mPicListView是RecyclerView对象
			mPicListView.setLayoutManager(mLayoutManager);
			mPicListView.setOnScrollListener(new OnScrollListener() {
				@Override
				public void onScrollStateChanged(RecyclerView recyclerView,
						int newState) {
					super.onScrollStateChanged(recyclerView, newState);
					//加载更多
					if (!isLoading
							&& hasMore
							&& mAdapter.getItemCount() == (mLayoutManager
									.findLastVisibleItemPosition() + 1)
							&& newState == RecyclerView.SCROLL_STATE_IDLE) {
						isLoading = true;
						requestServerArticleMore();
					}
				}

				@Override
				public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
					super.onScrolled(recyclerView, dx, dy);
					//解决RecyclerView和SwipeRefreshLayout共用存在的bug
					mRefreshLayout.setEnabled(mLayoutManager
							.findFirstCompletelyVisibleItemPosition() == 0);
				}
			});

这个我试了下，也能解决，但与单个item不会超过屏幕高度的情况下，上面的解决方法是可行的，反之就不行了。

找了好久，又找到了更好的解决办法：

recyclerView.setOnScrollListener(new RecyclerView.OnScrollListener(){
        @Override
        public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
            int topRowVerticalPosition =
                    (recyclerView == null || recyclerView.getChildCount() == 0) ? 0 : recyclerView.getChildAt(0).getTop();
            swipeRefreshLayout.setEnabled(topRowVerticalPosition >= 0);

        }

        @Override
        public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
            super.onScrollStateChanged(recyclerView, newState);
        }
    });

圆满解决问题。
