android dialog transparent

Question

I want to get rid of the border in my dialog box and make it look absolutly transparent, as if the image is on the top of screen.

Answer 1

To give a translucent effect, say 50% opacity, use:

Drawable d = new ColorDrawable(Color.BLACK);
d.setAlpha(130);
mDialog.getWindow().setBackgroundDrawable(d);

'130' can be changed (0-255) to acheive desired opacity.
