    How can I display empty groups?

    For example, I am listing appointments each day for a week (i.e. Sunday to Saturday); but if there are no events for a particular day, I still want to show that group.

    Hello Tracy,

    Thank you for your question.

    The groups are based on the items that you have, so if you don't have items in a group, such group will not be created. You can workaround this, by creating a Dummy appointment item for each day, this way you will have items for each group that you want to create. The easiest way not to show this item among the actual items would be to set the itemView's visibility to GONE in your adapter's onBindViewHolder when the item to be bound is a dummy item and set it to VISIBLE otherwise. You can also have another item view type for your dummy items if you would prefer.

    I hope this information helps.
