How to implement Material Design Choreographing surface animations : <p>I wonder how to implement the Choreographing surface animations (like <a href="https://material.google.com/motion/choreography.html#choreography-creation">https://material.google.com/motion/choreography.html#choreography-creation</a> in Choreographic surface section).</p>

<p>I actually used both Alpha animation and Translate animation but it seems like it is not exactly what we can see on the material design site.</p>

<p>Did someone have a good example of how to do this ?</p>
