    <p>I have a SQLite Database connection to my application, I have followed a Tutorial and that tutorial show the database in a SimpleCursorAdapter, this does the whole class to this adapter and my buttons can not fit in this class. I would therefore reduce this adapter to to fit with my buttons. Or is there any other better solution? For me the SimpleCursorAdapter Mix all my pictures an button to his adapter, I dont know but i think that the SCadapter makes the whole view into a list view and i dont want that. I have four classes. DBAdapter, Produkter (View) Car is the SimpleCursorAdapter ViewBinder and Bus is the Bitmap get, class</p> <pre><code>enter code here public class DBhelper { public static final String KEY_ID = BaseColumns._ID;

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.
