By default the cursor pointer points to the position before the first entry (row), so you need to move it to a proper position before you can read data from it. For example move to the first entry:

if(cursor != null && cursor.moveToFirst()) 
    String value = cursor.getString(0);
    ...
}

There are similar methods like moveToNext(), moveToLast() etc, see the reference page for more.
