CollectionView布局监听问题

请问，我现在使用CollectionView来进行布局，创建形如ListView的列表；但是我想根据列表中宽度最大的item的宽度来作为CollectionView的宽度，我该怎么做，设置了onLayout方法貌似没执行？
local tableView = CollectionView(tableViewData)
tableView:onLayout(function()
tableView:onLayout.adjustSize()--此处没调用
end)

Start with the CollectionView and onLayout usage shown in the issue, then reproduce the ListView-like layout with tableViewData. Trace whether the onLayout callback runs and how the largest item width is expected to affect the CollectionView; done means the callback behavior and required width adjustment are documented or verified.
