setActivated

void setActivated (boolean activated)

Parameters
activated boolean

setOnItemViewClickedListener

void setOnItemViewClickedListener (BaseOnItemViewClickedListener listener)

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(ViewGroup).

Parameters
listener BaseOnItemViewClickedListener

setOnItemViewSelectedListener

void setOnItemViewSelectedListener (BaseOnItemViewSelectedListener listener)

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.

Parameters
listener BaseOnItemViewSelectedListener

setOnKeyListener

void setOnKeyListener (View.OnKeyListener keyListener)

Sets a key listener.

Parameters
keyListener View.OnKeyListener

syncActivatedStatus

void syncActivatedStatus (View view)

Synchronizes the activated status of view to the last value passed through setActivated(boolean). No operation if setActivated(boolean) 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.

Parameters
view View

Hooray!
