Question

I am trying to use a cursorAapter to bindview two strings to a textView. However I seem to be getting a Resources not found exception. I don’t understand why as they are both 2 string types and I am making an entry at the beginning of the program so there will be something to display.

Answer 1

I guerss this line is the problem:

 text_modulecode.setText(c.getColumnIndex(database.KEY_MODULECODE));

the columnIndex is most likely an int, which is interpreted as a resourceId. Thats why it is searching for resource ID 1 (the column index). Use

....setText(String.valueOf(c.getColumnIndex(database.KEY_MODULECODE)));

to make sure you use the method that takes a String.
