Thank you for your answer.
Yes. I wasn't sure which way is better - using two cursors or using
one cursor with Custom CursorAdapter (and curosr inside custom View in
it).

I already posted the basic pattern two messages back.
As for nested data, you might want to use CursorAdapter (with subclassing)
instead of trying to fit nested queries to SimpleCursorAdapter, which is
more trouble than it's worth.
If you do, you won't need to iterate through the top-level query
Can you give me a link with an example of that?

You can use the pattern for the top level and the nested query both.

I tried to change my code this way. There is still a problem.
I tried to check for empty rows but even then I've got this exception
error.
Maybe the problem is in my way of dealing with those two cursors
(second cursor is in another)
Maybe I'll start from the beggining and you will tell me a bet

A cursor's initial position is -1, right before the first row, so it's quite
enough to do this:
Cursor cursor = . query ...
if (cursor != null) {
... get column indices here
while (cursor.moveToNext()) {
... get data using the indices here ...
}
cursor.close();
}

moveToFirst() will not fail, just return false if empty. Just check
the return value
before proceeding.

You received this message beca
Thanks. But this is strange.
When I add this condition
if(cursor.getCount() > 0) }
...
My ListView is empty. In LogCat everything looks fine.

Hi,
After you get a cursor object from a query, check the count before
doing "moveToFirst()".
if(cursor.getCount() > 0)
{
cursor.moveToFirst();
... processing ...
}
