There is no button for repeat. All music players have it. This should be fairly easy to do. The current buttons for the timer and volume, taken from the original implementation of the player, are still there but they could be replaced with those of shuffle and repeat. Also, apart from the button, some code behind-the-scenes would be required, this should be fairly easy as well, because Exoplayer contemplates the use of Repeat.
