OnItemViewSelectedListener

Called when the a row or a new item becomes selected. The concept of current selection is different than focus. Row or item can be selected even they don't have focus. Having the concept of selection will allow developer to switch background to selected item or selected row when user selects rows outside row UI (e.g. headers left of rows).

For a none ListRow case, parameter item is always null. Event is fired when selection changes between rows, regardless if row view has focus or not.

For a ListRow case, parameter item can be null if the list row is empty.

In the case of a grid, the row parameter is always null.
