public final void setActivated(boolean activated)

Sets the row view's activated status. The status will be applied to children through RowPresenter.ViewHolder.syncActivatedStatus(View). Application should only call this function when RowPresenter.getSyncActivatePolicy() is RowPresenter.SYNC_ACTIVATED_CUSTOM; otherwise the value will be overwritten when expanded or selected status changes.

public final void syncActivatedStatus(View view)

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

public void setOnKeyListener(View.OnKeyListener keyListener)

Sets a key listener.

public View.OnKeyListener getOnKeyListener()

Returns the key listener.

public final 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.

public final BaseOnItemViewSelectedListener getOnItemViewSelectedListener()

Returns the listener for item or row selection.

public final void setOnItemViewClickedListener(BaseOnItemViewClickedListener listener)
