ArrayIndexOutOfBoundsException while Scrolling

akohout commented 10 years ago

Hey,

first of: cool library!

But I'm facing one problem: When I open the view that contains the EnhancedListView and I start scrolling it simply crashes with an ArrayIndexOutOfBoundsException.

The according stack trace:

To my app:

I placed the EnhancedListView in my fragment layout
during the fragment's onViewCreated method I get a reference to the EnhancedListView, place an onItemClickListener, a DismissCallback, enable the swipe, and set the swipe direction
since the data is coming via an asynchronous network request, I set the adapter for the ListView in a callback method

Do you have any idea what's going on there? Do you need more code? :)

I receive the same exception when swiping a ListView entry:

I hope you know what's going on there..

I doubt I do :(

Looking at the stack trace, the only part of this libraries code is the plain call to super.onTouchEvent, and AbsListView crashes then somehow. Looking at this, it doesn't seem to be a bug in the library (though you never know, you only wish :D).

Could you perhaps replace the EnhancedListView in your layout with a ListView and comment out the methods, that don't exists on the ListView and see if it still crashes if you touch something?

akohout commented 10 years ago

Oh sh**, you're right ... doing it with a simple ListView also let the app break. I really hoped it was your library :D

Thanks for your advice and sorry for reporting a non-existing exception!

timroes commented 10 years ago

No problem. If you want an wild guess what you might be doing wrong:

Are you using getViewTypeCount() and getItemViewType() and returned an integer from getItemViewType equal or larger than you returned from getViewTypeCount() (or perhaps a negative number)?

akohout commented 10 years ago

Haha, yeah - you’re right with your wild guess :-) Awesome, thanks!

I had the same trouble when used multiple view types for the ListView. The trick is that view types must start from 0. And not forget to ovverride getViewTypeCount method.
