Android : Determine Position in Android SQLite Database

I want to be able to find the position of a string in a column. I have an app where the user adds to a list which forms a card and when they swipe the card, it deletes. I'm new to SQLite and I'm having a bad time trying to delete the items I want.

Here's what I have so far:

c2.moveToFirst();
String contentLabel = c2.getString(c2.getColumnIndex("Content"));
db.delete("Lists", "Content = '" + contentLabel + "'", null);

Now the problem with this is that when I swipe the card away, say, on the third card, the first card gets removed and the card that was swiped away moves to the top of the list.
