getView

public android.view.View getView(android.view.View convertView,
                                 android.view.ViewGroup parent)

Create/get a view that represents this content Arguments are optional and may be null (for use with recycler views)

Parameters:

convertView - The existing content view

parent - The parent view

Returns:

Content view or null if not supported

getMenu

public android.widget.PopupMenu getMenu(android.view.View anchor)

Create/get a menu for any actions associated with this content The menu may be used as a container for menu items/actions and not necessarily displayed as-is to the user. Avoid setting click listeners here since they may be ignored in this case. If this handler overrides PopupMenu.OnMenuItemClickListener.onMenuItemClick(android.view.MenuItem) then overriders shouldn't assume the menu item IDs will be consistent due to potential context mismatch issues. Consider checking actions using MenuItem.getTitle()

Parameters:

anchor - View anchor where this menu will be displayed May be null if the caller is using the menu as a container

Returns:

Menu containing a list of actions or null if not supported

getViewState

public MetaDataHolder getViewState()

Allow for retrieval name/value dataset associated with this content view

Returns:

the MetaDataHolder containing the information associated with the current state of the View. The return value is assumed to be mutable by the view at any time but changes are guaranteed when the URIContentListener::onContentChanged is fired. Can be null if not implemented. The view that is returned can be reused by setViewState without issue.

setViewState

public void setViewState(MetaDataHolder metaData)

Allow for setting of the name/value dataset associated with this content view

Parameters:

metaData - the metaData used to populate the view. The view is only populated when this method is called. Subsequent changes to this holder will have no effect on the visual content of the view unless the setViewState is called again. The view can be recycled from the view returned from getViewState();

isActionSupported

public boolean isActionSupported(java.lang.Class<?> action)

Check if an action with a given class is supported by this handler Besides the "instance of" check, this call may return false if a handler only supports a given action under other conditions i.e. visibility toggle is only supported if content exists on map

Parameters:

action - Action class

Returns:

True if supported
