title: Umano Android SlidingUpPanel - animation
body: <p>I am using the following project: <a href="https://github.com/umano/AndroidSlidingUpPanel" rel="noreferrer">https://github.com/umano/AndroidSlidingUpPanel</a></p>
  
  <p>It works very nicely so far, but I have one issue: I want to hide the slidable panel until I press a button, then the panel should be faded in, with an animation; currently the panel is shown when the button is pressed, but without an animation, and I don't know how to implement said animation.</p>
  
  <p>Any ideas would be very much welcome!</p>
