VideoView invisible in Popupwindow?

Question

My goal: I try to play the video when I click on one of the elements on the screen, remaining on this screen.

So I resort to PopupWindow, but somehow the VideoView does not appear in the popup.

I can display the popup just fine, but VideoView does not (in fact, it is not invisible, but rather freezes this section of the screen). If you look at the second and third screens, you will see that the invisible area is not exactly rectangular. This is because I revitalize popupwindow.

I checked VideoView itself inside another action and it plays great. I tested this with Nexus One and Galaxy S, both display the same result.

A quick search on StackOverflow reveals this question: Android video, listen to the sound, but there is no video that leads to Android does not play .mp4 video and both do not work for me.

In addition, as you can see on the third screen, MediaController does not exactly attach to a video or popupwindow, except for Activity.

Here are the screens
