/*
* InitListView method is to initiate the LoopStaggeredGridView component. There are 4 parameters:
* itemTotalCount: the total item count in the scrollview, this parameter should be >=0.
* layoutParam: this class is very sample, and you need new a GridViewLayoutParam instance and set the values you want.
* onGetItemByItemIndex: when an item is getting in the scrollrect viewport, this Action will be called with the item’ index as a parameter, to let you create the item and update its content.
* LoopStaggeredGridViewItem is the return value of onGetItemByItemIndex
* Every created item has a LoopStaggeredGridViewItem component auto attached
