Body
What I did with the SimpleCursorAdapter in my project is temporary set a SimpleCursorAdapter.ViewBinder. The method ViewBinder.setViewValue(...) is called when the list items become visible on the screen. Do the pre-selecting and remove itself. <pre><code> final SimpleCursorAdapter sca = new SimpleCursorAdapter(this, layout, c, from, to); mProjectListView.setAdapter(sca); // Add temporary ViewBinder for pre-selected ListView item // i.e. the current project should be selected final ViewBinder viewBinder = new ViewBinder() { @Override public boolean setViewValue(View view, Cursor cursor, int columnIndex) { String text = cursor.getString(columnIndex); String currentProject = mPreferences.getString(PREF_NAME, sDefName); if (currentProject.equals(text)) { mProjectListView.setItemChecked(cursor.getPosition(), true); // Remove itself sca.setViewBinder(null); } // Let CursorAdapter handle the binding, so return false return false; } }; sca.setViewBinder(viewBinder); </code></pre> Unfortunately the ArrayAdapter doesn't have this listener. So i override ArrayAdapter.getItem(int position) and introduce OnGetItemListener interface. <pre><code>public class CustomArrayAdapter<T> extends ArrayAdapter<T> { public static interface OnGetItemListener<T> { void onGetItem(int position, T item); } private OnGetItemListener<T> mGetItem = mNullGetItem; public void setOnGetItemListener(OnGetItemListener<T> listener) { if (listener != null) { mGetItem = listener; } else { mGetItem = mNullGetItem; } } @Override public T getItem(int position) { T item = super.getItem(position); mGetItem.onGetItem(position, item); return item; } } </code></pre> Using the CustomArrayAdapter: <pre><code> caa.setOnGetItemListener(new CustomArrayAdapter.OnGetItemListener<String>() { @Override public void onGetItem(int position, String item) { if (item.equals(<is it your item?>)) { mProjectListView.setItemChecked(position, true); caa.setOnGetItemListener(null); } } }); </code></pre>

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.
