Android SwipeRefreshLayout 、Recy

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);  
        }  
    });
