VideoView invisible in Popupwindow?

Question

My target: I am trying to play a video when tapping on one of the item on the screen while still staying on that screen.

So I resort to PopupWindow but somehow VideoView doesn't show up in the popup.

I can display popup just fine but the VideoView doesn't(in fact, it's not invisible but rather freeze that section of the screen). If you look at the second and third screen, you will see that the invisible area isn't exactly rectangular. That's because I am animating the popupwindow.
