    1. COHI. SimpleAdapter is called "Simple" because it is really simple. Actually you can extend it and "invent" something but it is not good idea. Please use CursorAdapter http://developer.android.com/reference/android/widget/CursorAdapter.html for your needs.

    3. CONo it is. CursorAdapter is basic approach for your task. It is much better from architecture and performance point of view. Give it a try. Currently you are inventing a "hook, how to use SimpleAdapter for the purpose it is not appropriate for".

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
