Собственно в java в есть AddAction (Детальнее написано здесь )
Notification notification = new Notification.Builder(context)
// Show controls on lock screen even when user hides sensitive content.
.setVisibility(Notification.VISIBILITY_PUBLIC)
.setSmallIcon(R.drawable.NotIcon)
//HERE ARE YOUR BUTTONS
.addAction(R.drawable.ic_prev, "BUTTON 1", myIntentToButtonOneScreen) // #0
.addAction(R.drawable.ic_pause, "BUTTON 2", myIntentToButtonTwoScreen) // #1
.addAction(R.drawable.ic_next, "BUTTON 3", myIntentToButtonThreeScreen) // #2
// Apply the media style template
.setStyle(new Notification.MediaStyle()
.setShowActionsInCompactView(1)
.setMediaSession(mMediaSession.getSessionToken())
.setContentTitle("Example for you")
.setContentText("Example for you")
.setLargeIcon(ButtonExampleIcon)
.build();
Но в TNotification ничего подобного нет
