↳	android.support.v4.media.TransportController

Known Direct Subclasses

TransportMediator

Class Overview

Base interface to controlling a media transport. This is the interface for implementing things like on-screen controls: it allows them to request changes in playback, retrieve the current playback state, and monitor for changes to the playback state.

Public Methods
abstract int	getBufferPercentage() Retrieve amount, in percentage (0-100), that the media stream has been buffered on to the local device.
abstract long	getCurrentPosition() Retrieve the current playback location in the media stream, in milliseconds.
abstract long	getDuration() Retrieve the total duration of the media stream, in milliseconds.
abstract int	getTransportControlFlags() Retrieve the flags for the media transport control buttons that this transport supports.
abstract boolean	isPlaying() Return whether the player is currently playing its stream.
abstract void	pausePlaying() Request that the player pause its playback and stay at its current position.
abstract void	registerStateListener(TransportStateListener listener) Start listening to changes in playback state.
abstract void	seekTo(long pos) Move to a new location in the media stream.
abstract void	startPlaying() Request that the player start its playback at its current position.
abstract void	stopPlaying() Request that the player stop its playback; it may clear its state in whatever way is appropriate.
abstract void	unregisterStateListener(TransportStateListener listener) Stop listening to changes in playback state.

Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Public Methods

public abstract int getBufferPercentage ()

Retrieve amount, in percentage (0-100), that the media stream has been buffered on to the local device. Return 100 if the stream is always local.

public abstract long getCurrentPosition ()

Retrieve the current playback location in the media stream, in milliseconds.

public abstract long getDuration ()

Retrieve the total duration of the media stream, in milliseconds.

public abstract int getTransportControlFlags ()

Retrieve the flags for the media transport control buttons that this transport supports. Result is a combination of the following flags: FLAG_KEY_MEDIA_PREVIOUS, FLAG_KEY_MEDIA_REWIND, FLAG_KEY_MEDIA_PLAY, FLAG_KEY_MEDIA_PLAY_PAUSE, FLAG_KEY_MEDIA_PAUSE, FLAG_KEY_MEDIA_STOP, FLAG_KEY_MEDIA_FAST_FORWARD, FLAG_KEY_MEDIA_NEXT

public abstract boolean isPlaying ()

Return whether the player is currently playing its stream.

public abstract void pausePlaying ()

Request that the player pause its playback and stay at its current position.

public abstract void registerStateListener (TransportStateListener listener)

Start listening to changes in playback state.

public abstract void seekTo (long pos)

Move to a new location in the media stream.

Parameters

pos	Position to move to, in milliseconds.

public abstract void startPlaying ()

Request that the player start its playback at its current position.

public abstract void stopPlaying ()

Request that the player stop its playback; it may clear its state in whatever way is appropriate.

public abstract void unregisterStateListener (TransportStateListener listener)

Stop listening to changes in playback state.
