Constructor Detail

StaticPlaylistController

public StaticPlaylistController(int mainViewId,
                                int listviewId,
                                Activity activity,
                                List<TrackMetadataBean> tracks,
                                boolean addActivated)

Creates new controller.

Parameters:

mainViewId - the view whose visibility is controlled.

listviewId - the list view id

activity - the parent activity.

tracks - initial track list.

addActivated - if true then the activated items are added at the end of the playlist.

Method Detail

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.

getPlaylistSize

protected int getPlaylistSize()

Description copied from class: AbstractPlaylistController

Returns the underlying playlist size.

Specified by:

getPlaylistSize in class AbstractPlaylistController

Returns:

the playlist size.

getTrack

protected TrackMetadataBean getTrack(int index)

Description copied from class: AbstractPlaylistController

Retrieves a track from given position.

Specified by:

getTrack in class AbstractPlaylistController

Parameters:

index - the index

Returns:

the track instance, never null.

isCurrentlyPlayedTrack

protected boolean isCurrentlyPlayedTrack(int index)

Description copied from class: AbstractPlaylistController

Checks if the track at given index is currently being played.

Specified by:

isCurrentlyPlayedTrack in class AbstractPlaylistController

Parameters:

index - the track index

Returns:

true if it is being played, false otherwise.

removeItems

public void removeItems(Interval remove)

Description copied from class: AbstractPlaylistController

The contract: when overriding this method, be sure to call this super method after you are done deleting items. The adapter must be invalidated, to prevent drawing old data.

Specified by:

removeItems in interface IGestureListViewListener

Overrides:

removeItems in class AbstractPlaylistController

Parameters:

remove - the interval to remove

moveItems

public Interval moveItems(Interval highlight,
                          int index)

Description copied from interface: IGestureListViewListener

Move selected items up or down. The listener must update the items and return the new highlight. This operation is always considered as a short-running and thus always executed directly in handler's event thread.

The list view will be redrawn automatically when the method returns.

This operation is invoked only when IGestureListViewListener.isReadOnly() returns false.

Specified by:

moveItems in interface IGestureListViewListener

Overrides:

moveItems in class AbstractListController

Parameters:

highlight - move these items

index - drop the items before item with this index.

Returns:

new interval which contains all moved tracks.

moveItemsByOne

public Interval moveItemsByOne(Interval highlight,
                               boolean down)

Description copied from interface: IGestureListViewListener

Move selected items up or down. The listener must update the items and return the new highlight. This operation is always considered as a short-running and thus always executed directly in handler's event thread.

The list view will be redrawn automatically when the method returns.

This operation is invoked only when IGestureListViewListener.isReadOnly() returns false.

Specified by:

moveItemsByOne in interface IGestureListViewListener

Overrides:

moveItemsByOne in class AbstractListController

Parameters:

highlight - move these items

down - down if true then move the highlighted interval down, otherwise move it up.

Returns:

new interval which contains all moved tracks.

getTracks

public List<TrackMetadataBean> getTracks()

Returns an unmodifiable view on the track list.

Returns:

list of tracks.

getHint

public String getHint(Interval highlight)

Description copied from interface: IGestureListViewListener

Returns a very short and simple string representation of the selected contents.

This method is only invoked when IGestureListViewListener.canComputeItems() returns true.

Specified by:

getHint in interface IGestureListViewListener

Specified by:

getHint in class AbstractPlaylistController

Parameters:

highlight - the highlighted items.

Returns:

short description of selected contents. May be null if no hint should be shown.

getQueueNumber

protected int getQueueNumber(int index)

Description copied from class: AbstractPlaylistController

Returns queue status of given track.

Specified by:

getQueueNumber in class AbstractPlaylistController

Parameters:

index - the track index

Returns:

queue number or 0 if the track is not queued.

setResults

public void setResults(List<TrackMetadataBean> tracks,
                       String query,
                       SearchType type)

Shows given search result on the list view.

Parameters:

tracks - the model to show.

query - the query

type - hint on the type of data in the model.

setTracks

public void setTracks(List<TrackMetadataBean> tracks)

Sets new track list.

Parameters:

tracks -

stateChanged

public void stateChanged(AppState state)

Description copied from interface: IApplicationListener

The application state was changed.
