MODE_SINGLE_ITEM_TEMP - The same as the default behavior.
MODE_SINGLE_ITEM_PERMANENT - Single item is selected and the selection remains.
MODE_MULTIPLE_ITEMS- Multiple items can be selected.
There is also a helper method that selects an item and makes it visible.
Usage:

Implement the ItemClick event:
If using lazy loading then also call from VisibleRangeChanged (at the end):
Depends on B4XCollections, xCustomListView and XUI libraries.
