Fix RuntimeException when unmarshalling data

[kquan]

I noticed a bug when using the SlideExpandableListView. The reproduction of the bug is as follows:

1. In Android OS settings, go under Developer options and enable "Do not keep activities"
2. In Android app, navigate until you get to an activity that uses the SlideExpandableListView
3. (Optional) I enabled the expansion on the list view
4. Jump directly out of the app (i.e., press home key)
5. Open the app again through the launcher or task switch

This will cause an exception similar to the following:

After debugging, I noticed this issue is similar to that described by this SO article:
http://stackoverflow.com/questions/19672772/parcel-unmarshalling-unknown-type-code

It looks like the code in SavedState has the code for writing and reading the parcel reversed. This patch resolves this problem.

I supposed you tested this. So i'll me lazy and merge it

[MrDoLoop]

Can you add new features?
When the last item in the list is expended, is it possiable that smoothly scroll up some distance, in order to let expandable area visible.

Thanks

@MrDoLoop I had a similar requirement but I was able to get around it without editing the library code by adding an OnClickListener on the view and then using a ViewTreeObserver to scroll up the list as needed if the height of the expanded list item exceeds the bottom of the list.

Thanks so much for your attention.
Could you share me some pieces of snippet? I never used ViewTreeObserver
before

Appreciate your attention.
