Android java.lang.IndexOutOfBoundsException: Invalid index 0, size is 0

Question

I have a ToDo App and I need to sort two ArrayLists - first with Strings(entry name given by the user) and second with Bitmaps(image added by the user as an attachment to the entry). If I'll sort ArrayList with Strings I have to sort an array with Bitmaps too, because Bitmaps have to match the Strings. Sorting of the first arraylist(Strings) works just fine but with the second arraylist(Bitmasp) don't. I'm getting this error:

Answer 1

You can use Maps instead of two different Arraylists for storing strings and bitmaps.

You can have strings as keys and bitmaps as values and iterate the Maps to get the results of a specific index.

I hope this would solve your problem.
