// 数据发生了改变，那调用这个方法，传入改变对象的位置。
public final void notifyItemChanged(int position);

不是，我的意思是，DEMO里的数据好像是一次性拿到所有，然后去做分页，但是如果是一开始从网络上拿数据的时候就做分页处理呢，这个也是和Demo上的处理方式一样么？

恩是的一样的。

那addData()这个方法里传的值就是网络数据请求的所有数据么？

                                }
                            }

                        }, 1);
                    }
                });
            }
            swipeRefreshLayout.setRefreshing(false);
        }

        @Override
        public void onError(Context context, String errorCode, String title, String message) {
            super.onError(context, errorCode, title, message);
        }
    });
}

@Override
public void onRefresh() {
    homePagePlanAdapter.setEnableLoadMore(false);
    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            homePagePlanAdapter.setNewData(homePagePlanList);
            isErr = false;
            mCurrentCounter = PAGE_SIZE;
            swipeRefreshLayout.setRefreshing(false);
            homePagePlanAdapter.setEnableLoadMore(true);
        }
    }, 1);
}

} 这是我写的分页加载网络数据的方法，但是有问题，我是按照Demo的写法写的，所以麻烦帮我看下在自动加载那里出了什么问题啊

从新开个issues，并且附上版本号，代码使用代码块包裹，还有xml布局代码。谢谢这样便于我们更快定位问题。
