Not able to acomplish Sticky header

I did all the steps according to the wiki and the demo but the headers are not sticking at all. The sections are fine but the header scrolls out of the page @davideas What else I should try?

Obs:

• ‘eu.davidea:flexible-adapter:5.0.0-b8’

• Using the same fragment_recycler_view.xml

• HeaderItem extends AbstractHeaderItem<HeaderItem.HeaderViewHolder>

• Item extends AbstractFlexibleItem<Item.ItemViewHolder> implements ISectionable<Item.ItemViewHolder, HeaderItem>

    adapter = new FlexibleAdapter<>(items);
    recycler.setLayoutManager(new SmoothScrollLinearLayoutManager(getContext()));
    adapter.setDisplayHeadersAtStartUp(true);
    adapter.enableStickyHeaders();
    recycler.setAdapter(adapter);
    recycler.setHasFixedSize(true);
    recycler.setItemAnimator(new DefaultItemAnimator());

@davideas Found it! I was implementing this method wrong. Now it works!

@Override
  public boolean equals(Object inObject) {
    if (inObject instanceof HeaderItem) {
      HeaderItem inItem = (HeaderItem) inObject;
      return this.getId().equals(inItem.getId());
    }
    return false;
  }

@leodeleon22, I see now that, you enable the headers before setting the Adapter. Move the assignment after. The layout needs the RV attached (means not null) before inflating the sticky container.

Be aware that I’m going to change this configuration, in the next pre-release.
