isOpen / openItem / closeItem / setMode are not working

im using a recycler view, here is adapter:

```
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view;
if (viewType == TYPE_ITEM) {
view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item, parent, false);
view.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
List list = Adapter.this.getOpenItems();
return false;
}
});
return new MemberListViewHolder(view);
} else {
view = LayoutInflater.from(parent.getContext()).inflate(R.layout.header, parent, false);
return new HeaderViewHolder(view);
}
}
```

i put a header view in recycler, isOpen / openItem / closeItem / setMode are not working.
