removeFooterView和addFooterView方法不能改变footer样式

调用DefaultTipsHelper中的getHeaderAdapter().removeFooterView方法时出现问题。 DefaultTipsHelper中的showHasMore方法用来显示加载中的样式，我想新增一种样式用来显示“没有更多数据了”比如叫showNoMore，参考DefaultTipsHelper中的实现，showNoMore中的具体实现是：

mFragment.getHeaderAdapter().removeFooterView(mLoadingView);
mFragment.getHeaderAdapter().addFooterView(mNoMoreView); 但是页面仍然显示的是mLoadingView，为什么mNoMoreView显示不出来呢？

另外，调用removeAllFooterView也无效。

错误日志是
