Sticky Headers not working on 5.0.0-SNAPSHOT about flexibleadapter

Thanks this fixed it. Completely overlooked the equals method.

Hello @jonathanyee, I think the mistake is in the Override of the equals method, it is not correctly implemented, the cast to String is never done because the o is an instance of RecentContactHeaderItem, so you should do something like this if you want to check the title:

@Override
public boolean equals(Object o) {
    if (o instanceof RecentContactHeaderItem) {
        RecentContactHeaderItem  oo = (RecentContactHeaderItem ) o;
        return oo.title.equals(this.title);
    }
    return false;
}

Pay attention to the null values.
Same mistake for RecentContactItem.

Have a look at this page Writing a correct equals method to implement your own equals method.

I've put it mandatory to implement, because in most cases we identify the items with our "id", otherwise the basic implementation is return o == this, you can also use it.

I'm working on expandable sections that are also a Header. However I've committed already something in dev yesterday evening, But I did not yet created a new snapshot, I'll do it very soon. The adapter needed a tiny modification internally.
