I believe one of the main goals of GPLv3 was to prevent people exploiting loopholes they'd found in earlier versions, so I don't think this will be a possibility.
If this is a show-stopper for you, it might be worth contacting Jeff to see if you can license code on different terms - Applying GPL to code doesn't stop it being made available by the author/copyright hold under a different license.
That said, doesn't ExpandableListAdapter and ExpandableListView do almost the same job, if you override the expand/collapse behaviour?
Hope this helps,
