Called attach on a child which is not detached

当你的 adapter 添加了headview，adapter.notifyDataSetChanged()就会报Called attach on a child which is not detached

解决办法是如果你添加了headView,那么notifyItemChanges 的index+1

所以adapter.notifyDataSetChanged()替换成adapter.getAdapter().notifyItemChanged(index + 1)

代码如下

var layoutManager = recyclerView.layoutManager as LinearLayoutManager;
var mLastVisibleItemPosition = layoutManager.findLastVisibleItemPosition();
var mFirstVisibleItemPosition = layoutManager.findFirstVisibleItemPosition();
for(index in mFirstVisibleItemPosition..mLastVisibleItemPosition)
    if(headView!=null) 
        adapter.getAdapter().notifyItemChanged(index + 1);
    else
        adapter.getAdapter().notifyItemChanged(index);
