Creates new playlist manager controller instance.

Method Detail

onAction

protected void onAction(ActionsEnum action)

Description copied from class: AbstractController

Called when an action button is pressed. By default invokes main activity. Subclasses can override.

Overrides:

onAction in class AbstractController

Parameters:

action - the action to take

savePlaylistWizard

public void savePlaylistWizard(Context context)

Navigates user through a 'save playlist' wizard.

Parameters:

context - the context.

recomputeListItems

protected void recomputeListItems()

Description copied from class: AbstractListController

Recomputes the model. You don't have to call the ModelHolder.notifyModified() - it is called automatically after the method finishes.

Specified by:

recomputeListItems in class AbstractListController

isReadOnly

public boolean isReadOnly()

Description copied from interface: IGestureListViewListener

Checks if the list view is currently read-only.

Specified by:

isReadOnly in interface IGestureListViewListener

Overrides:

isReadOnly in class AbstractListController

Returns:

true if the view cannot be modified, false otherwise.

itemActivated

public void itemActivated(int index,
                          Object model)

Description copied from interface: IGestureListViewListener

The item was activated, either by clicking on it or using a keyboard.

Parameters:

index - the index of the item.

model - the model for the item.

loadPlaylist

public void loadPlaylist(String name)

Loads playlist with given name. Shows an error message when the playlist failed to be loaded.

Parameters:

name - the name of the playlist.

removeItems

public void removeItems(Interval remove)

Description copied from interface: IGestureListViewListener

Remove these items from the list. The list view sets the highlight automatically to zero interval.

This operation is invoked even when IGestureListViewListener.isReadOnly() returns false as some use cases activates a "Go Back" activity instead of deleting items.

Specified by:

removeItems in interface IGestureListViewListener

Overrides:

removeItems in class AbstractListController

Parameters:

remove - remove these items. The interval is not null however it may be empty.

update

public void update(GesturesListView listView,
                   View itemView,
                   int index,
                   Object model)

Description copied from interface: IGestureListViewListener

An item view is being drawn (or re-drawn) on screen. The implementation should correctly set the view contents, based on the model object. The model object is taken from the GesturesListView.getModel() list. The only exception is the EOP special item. For more information please read here.

Parameters:

listView - the listview containing the view

itemView - the view representing a single item

index - the index in the GesturesListView.getModel() list. May point outside of the model list only when drawing an EOP item.

model - The model object, taken from the GesturesListView.getModel() list. This value may optionally be the MutableListAdapter.EOP_MODEL_MARKER object - in this case the special EndOfPlaylist item must be drawn.

performZoom

protected void performZoom(boolean zoom)

Description copied from class: AbstractController

Zooms, or un-zooms the controller.

Overrides:

performZoom in class AbstractListController

Parameters:

zoom - true zoom the controller in, false zoom the controller out.
