How to remove unneccesary View behind DatePickerDialog?

Question

I implemented this example from here. There in that example you can see he is running with a dialog style like this old style for DatePickerDialog without border

When I use this, I can clearly see an additional view behind that dialog: date picker dialog with border

How can I remove that additional view behind MY date picker dialog?

Answer 1

Try:

dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
