BaseOnItemViewSelectedListener

fun onItemSelected(
    itemViewHolder: Presenter.ViewHolder!,
    item: Any!,
    rowViewHolder: RowPresenter.ViewHolder!,
    row: T!
): Unit

Called when a row or a new item becomes selected.

For a non ListRow case, parameter item may be null. Event is fired when selection changes between rows, regardless if row view has focus or not.

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

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

• Row has focus: event is fired when focus changes between children of the row.
• No row has focus: the event is fired with the currently selected row and last focused item in the row.
