We are currently working on a project for Android, doing some augmented reality stuff. For this project, we need to make the video played in VideoView transparent. Starting with version 3.0, the setAlpha () method must exist for the VideoView class. But if you change the alpha value using this method, nothing will happen to the view.
Maybe it’s also relevant ... the videoView is placed at the top of the GlSurfaceView, which itself will fit on top of the Surfaceview showing the camera image.
Maybe someone got an idea why setAlpha is not working?
