Android Question Remove panel animation inside the scrollview

Hi everybody,

I have the attached layout. In this layout I have scrollview which holds type A panels which they also hold type B panels. Number of panels are varies.

What I need is to remove type B panel with an animation like fade first and scroll up all the panels below. Of course if all the type B panels removed from the type A panel I want to animate the removal of that panel too.

So what is the proper and easy way to achieve this remove panel animation.

Thanks in advance.
