hi,
I want to perform onClick event on Headers Items, so how can i do it, with this library.

尝试着把HeaderRecyclerView的头布局改成listview或者gridview或者其他滚动控件，无法友好加载头部

supclass get item view type from RecyclerView.ViewHolder is not correct,not equals i provider in getContentViewType(int dataListIndex) method.i think should use other method to separate content view item type from header view type and footer view type without modification content item view type.

我english很差，你将就着看

Hi,

Is there any links where i can look up for examples?

你好 :) 最近在参考这个 RecyclerViewUtils 改进自己的 RecyclerView 工具集，但发现 BaseWrapperRecyclerAdapter 中用了比较多的 notifyDataSetChanged()，动画蛮不自然的，尤其是 这里 以及其中提到的 #3 。

后来发现 这里 的 Load more view 的 view holder 不应该是 UnRecyclableViewHolder；换成 return new RecyclerView.ViewHolder(mLoadMoreFooterView) {}; 应该就可以了。

如果这个 ViewHolder 不能 recycle 的话，hideLoadMoreView() 再 showLoadMoreView() 就会出现 #3 提到的问题。

这样很多地方的 notifyDataSetChanged() 都能用细粒度的 notify 方法替代掉吧，感觉效果会好一些？

这个项目很久没有更新了，不知道这段时间有没有更好的优化呢？
发现几处需要优化的地方：
1.拖住不放会出现列表抖动的情况；
2.建议上拉和下拉进度条分开，上下各一个；
3.回弹效果和拉的不够顺畅；

有时间可否一起优化下

就是 既能展开，又能下滑的时候 保持头部

在index那个条目中滑动会闪烁，目测是子条目滑到最顶端会暂时覆盖头部条目

public void addAll(List list, boolean notifyDataChange) {
if (list == null || list.isEmpty()) {
return;
}
mItemList.addAll(list); //(1)
if(notifyDataChange) {
try {
notifyItemRangeInserted(mHeaderSize + getBasicItemCount(), list.size());//(2)
} catch (Exception e) {
Log.w(TAG, "notifyItemRangeInserted failure");
e.printStackTrace();
notifyDataSetChanged();
}
notifyDataSetChanged();
}
}

in addAll method, after notifyItemRangeInserted method ,call notifyDataSetChanged is redundant.

由于英文环境下values-en的优先级比values高，资源覆盖顺序会出现如下问题：
RecyclerViewUtils/library/src/main/res/values-en/strings.xml 优先级最高
MyApp/src/main/res/values/strings.xml 优先级次之
RecyclerViewUtils/library/src/main/res/values/strings.xml 优先级最低
结果就是我的app_name变成RALMDemo了。

解决方法也有：就是我自己再定义一个values-en/strings.xml，或者不用app_name这个字串。

不过我想作为一个公用的库，app_name这种常用字符串还是不要占用了吧:)

你好，我在使用你的demo过程中遇到一个问题：在使用RefreshRecycleView 只加载了两页的数据，后面的数据不加载了，不知道什么原因造成的。

请求的数据回调：
@OverRide
public void getMsg(List messages) {

    if(currentpage ==1){
        simpleAdapter.clear();
    }

    simpleAdapter.appendToList(messages);
    simpleAdapter.notifyDataSetChanged();

    mWrapperRecyclerView.refreshComplete();
}
@Override
public void onRefresh() {
    currentpage = 1;
     msgIPresenter.getData(currentpage);
    simpleAdapter.hideFooterView();
    mWrapperRecyclerView.getRecyclerView().scrollToPosition(0);
}

@Override
public void onLoadMore(final int pagination, int pageSize) {

    mWrapperRecyclerView.postDelayed(new Runnable() {
        @Override
        public void run() {
            currentpage++;

//开始请求数据
msgIPresenter.getData(pagination);

            simpleAdapter.showLoadMoreView();
            simpleAdapter.hideFooterView();
        }
    },1000);

}

原因：EndlessRecyclerOnScrollListener的checkCanBePulledDown方法仅对firstCompletelyVisibleItemPosition做了判断，当该值小于等于0，则判断为可拉出下拉刷新控件
public boolean checkCanBePulledDown() {
int firstPos = mLinearLayoutManager.findFirstCompletelyVisibleItemPosition();
return firstPos <= 0;
}
这样当item或header的高度超过一屏时，完全可见的item不存在，于是出现没有滚至顶部时就拉出下拉刷新的BUG。

解决方法如下
在WrapperRecyclerView中：
return mEndlessRecyclerOnScrollListener.checkCanBePulledDown();

替换为：
if(getChildCount() == 0) return true;
int firstVisiblePosition = linearLayoutManager.findFirstVisibleItemPosition();
if(firstVisiblePosition != 0) return false;
View firstVisibleView = linearLayoutManager.findViewByPosition(firstVisiblePosition);
int top = firstVisibleView.getTop();
return top >= 0;

大哥，能做个加载超时的功能吗，有些时候没有网络时，会一直在加载状态。顺便问下大哥做android多久了，我还是小弟呢。

i hope u have worked on girdlayoutmanager and staglayoutmanager

1. We are passing list within the constructor of simple expandable adapter. Everything seems fine.
2. On click event of item view, we are adding data to the existing list and calling notifyDataSetChanged(); but it seems the adapter is not getting that and hence, not updating the existing list!

From this case I have done it before that will able to support interval view generator appearing in between content views. referencing from here. is that possible to support that in ur library?

Is it possible to create header id is String ?

added header view in the grid layout manager. it has problem when it scrolling upward after the refresh is pulled. constantly appears. repeating the header view.

可能是我没用对,也可能确有bug

目前暂时解决办法是在EndlessRecyclerOnScrollListener中的onScrollStateChanged()方法中进行判断;
如果距上次触发onScrollStateChanged()时间不到1秒就直接return.
不知道有没有更好的解决办法
我用的不是最新版,由于我目前是直接改了EndlessRecyclerOnScrollListener, 并没有直接换最新.
不知道最新版还有没有这个问题

// 找到了解决办法
//另外,
//有时候划动到底部已经没有更多数据,但footer仍然是loading状态, 需要稍微下拉再上划才变成end状态
