CursorIndexOutOfBoundsException problem:Index 4 requested, with a size of 4

Question

I want to display for each maker an AlertDialog that has some description, for that, i\'m using this code:

protected boolean onTap(int index) {
            db =          


        

Answer 1

Array indexing starts with 0, not 1. your fourth element is stored at index 3.

When i put cur.moveToPosition(index); under String description = cur.getString(cur.getColumnIndexOrThrow("description")); i have Index -1 requested, with a size of 4 otherwise, like above code Index 4 requested, with a size of 4

When the row set is first returned the cursor will be at positon -1, which is before the first row.
