HamburgerMenuDrawable by

Recently I came accross some articles on Dribble which were showing some animated menu buttons, commonly called Burger buttons. An example of this is illustrated on this page: https://dribbble.com/shots/1654493-Hamburger-Icon-in-Framer?list=users&offset=1

After a bit of search and help of Flavien Laurent and his project TickPlusDrawable (https://github.com/flavienlaurent/tickplusdrawable), I found a simple solution involving subclassing the Drawable class. Then we just have to play with AnimatorSet and ObjectAnimator to animate the lines and make a cross and a hamburger appear successively.
