We learned how we can use CoordinatorLayout to handle the motion of its child views. Some views have built-in behaviors that handle how they work inside CoordinatorLayout. You can add custom behaviors to other views too. Then, we moved on to using MotionLayout to create animations by specifying the start constraint, end constraint, and the transition between them. We also looked into modifying the motion path by adding keyframes in the middle of the animation. We learned...
