Does it support changing the background color of BulrView?

Hello, I want to change the background color of BulrView to black with transparency. However, it seems that there is no method provided externally for such modification.

I'm not sure what exactly you're trying to achieve.
The "background" of the BlurView is the blurred snapshot, so whatever background you set is going to be covered by the blur, unless the blur is disabled.
If the disabled blur is the case you want to handle, you can set the background the same way you set it for any other View.
If you're talking about overlay (foreground) color, you can use setOverlayColor

Hello, if I want to add a gradient background to BlurView, which is not a simple Color, but a ShapeDrawable or LayListDrawable, what should I do

You may try setting it as foreground or extending/wrapping BlurView and setting this drawable there
