How should I override VideoView's onDraw in order for it to have transparent rounded corners?

android, android-videoview

Solution

Transparent rounded corners cannot be done with a `VideoView` or any `SurfaceView`, as according to the documentation:

The surface is Z ordered so that it is behind the window holding its SurfaceView; the SurfaceView punches a hole in its window to allow its surface to be displayed.

With a `TextureView` it seems theoretically possible, as its supposed to behave like a normal view. However I was unable too: Tried Porter Duff modes of both the `TextureView` layer paint and a `ShapeDrawable` in the foreground of the parent `FrameLayout`.

With a `VideoView`, what you can do is make corners of a solid color. Use a 9-patch with transparent content and just the corners of a solid color and set in on an `ImageView` that gets drawn on top.

Edit: Check this example project.

Problem

Clearly using a background shape doesnt work in the case of VideoView Also, there are lots of articles how to override onDraw for ImageView and make its corners round. But how do I do it for a VideoView?
