    1. COMake sure that your "CustomAdapter" is able to display a normal array or ArrayList. When this works - you should also be able to display a sorted data set.

    2. COyou dont need to use notifyDataSetChanged() method, when you are setting new adapter to list. Just paste your adapter code and activity code.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
