setActivated
fun setActivated(activated: Boolean): Unit
Sets the row view's activated status. The status will be applied to children through syncActivatedStatus. Application should only call this function when getSyncActivatePolicy is SYNC_ACTIVATED_CUSTOM; otherwise the value will be overwritten when expanded or selected status changes.
setOnItemViewClickedListener
fun setOnItemViewClickedListener(listener: BaseOnItemViewClickedListener!): Unit
Sets the listener for item click event. RowPresenter does nothing but subclass of RowPresenter may fire item click event if it has the concept of item. OnItemViewClickedListener will override View.OnClickListener that item presenter sets during onCreateViewHolder.
setOnItemViewSelectedListener
fun setOnItemViewSelectedListener(listener: BaseOnItemViewSelectedListener!): Unit
Sets the listener for item or row selection. RowPresenter fires row selection event with null item. A subclass of RowPresenter e.g. ListRowPresenter may fire a selection event with selected item.
setOnKeyListener
fun setOnKeyListener(keyListener: View.OnKeyListener!): Unit
Sets a key listener.
syncActivatedStatus
fun syncActivatedStatus(view: View!): Unit
Synchronizes the activated status of view to the last value passed through setActivated. No operation if setActivated is never called. Normally application does not need to call this method, ListRowPresenter automatically calls this method when a child is attached to list row. However if application writes its own custom RowPresenter, it should call this method when attaches a child to the row view.
