ListActivity with Cursor

Does anyone know of a simple example that uses the CursorAdapter? Here's what I'm doing now and it's crashing with a RuntimeException. I'm sure it something simple I'm missing given that I'm a newbie and can't find any simple examples of a ListView that uses a Cursor.

Thanks,

...

public final class MyListActivity extends ListActivity { private class MyCursorAdapter extends CursorAdapter { public MyCursorAdapter(Context context, Cursor cursor) { super(context, cursor); // CRASH ...

protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    myDB_ = new MyDB(this);
    myDB_.open();

    Cursor cursor = myDB_.read();
    startManagingCursor(cursor);

    MyCursorAdapter adapter = new MyCursorAdapter(this, cursor);

...

You can use setViewBinder on a SimpleCursorAdapter to map values to views not supported by the SimpleCursorAdapter itself. You can see an example of using setViewBinder to bind data from the content provider to a CheckBox here: CheckBox checked state in a ListView

You could use setViewBinder to bind your images to your imageButtons. That way, you don't have to create your own ListAdapter.

The Notepad tutorial in the Android developer resources uses a CursorAdapter with ListView. You can find the relevant part of the tutorial here: http://developer.android.com/resources/tutorials/notepad/notepad-ex1.html
