NotificationCompat.MediaStyle

public static class NotificationCompat.MediaStyle
extends NotificationCompat.Style

java.lang.Object
   ↳ android.support.v4.app.NotificationCompat.Style
     ↳ android.support.v4.media.app.NotificationCompat.MediaStyle
Known Direct Subclasses


Notification style for media playback notifications. In the expanded form, up to 5 actions specified with #addAction(int, CharSequence, PendingIntent) addAction will be shown as icon-only pushbuttons, suitable for transport controls. The Bitmap given to #setLargeIcon(android.graphics.Bitmap) setLargeIcon() will be treated as album artwork. Unlike the other styles provided here, MediaStyle can also modify the standard-size content view; by providing action indices to setShowActionsInCompactView(int) you can promote up to 3 actions to be displayed in the standard view alongside the usual content. Notifications created with MediaStyle will have their category set to CATEGORY_TRANSPORT unless you set a different category using setCategory(). Finally, if you attach a MediaSession.Token using setMediaSession(MediaSessionCompat.Token), the System UI can identify this as a notification representing an active media session and respond accordingly (by showing album artwork in the lockscreen, for example). To use this style with your Notification, feed it to setStyle(NotificationCompat.Style) like so:

 Notification noti = new NotificationCompat.Builder()
     .setSmallIcon(R.drawable.ic_stat_player)
     .setContentTitle("Track title")
     .setContentText("Artist - Album")
     .setLargeIcon(albumArtBitmap))
     .setStyle(new NotificationCompat.MediaStyle()
         .setMediaSession(mySession))
     .build();

setShowCancelButton

added in version 26.1.0
NotificationCompat.MediaStyle setShowCancelButton (boolean show)

Sets whether a cancel button at the top right should be shown in the notification on platforms before Lollipop.

Prior to Lollipop, there was a bug in the framework which prevented the developer to make a notification dismissable again after having used the same notification as the ongoing notification for a foreground service. When the notification was posted by startForeground(int, Notification), but then the service exited foreground mode via stopForeground(boolean), without removing the notification, the notification stayed ongoing, and thus not dismissable.

This is a common scenario for media notifications, as this is exactly the service lifecycle that happens when playing/pausing media. Thus, a workaround is provided by the support library: Instead of making the notification ongoing depending on the playback state, the support library provides the ability to add an explicit cancel button to the notification.

Note that the notification is enforced to be ongoing if a cancel button is shown to provide a consistent user experience.

Also note that this method is a no-op when running on Lollipop and later.

Parameters
show boolean: whether to show a cancel button

Returns
NotificationCompat.MediaStyle
