Issue with custom alert dialog

Question

I'm using a custom layout for an alert dialog, in which I set a custom background image.

When displayed, it seems that the dialog box is higher than my image background, while I set the layout dimensions to the image dimensions.

How can I set the dialog box dimensions to the dimensions of my background image? How can I remove this white border?

Thanks

enter image description here

dialog layout

            startActivity(i);

    }
};

@CapDroid: 279px X 130px. I set the dimensions of the LinearLayout to these dimensions. — jul

It looks like the dialog reserves this space for its title. See Android: How to create a Dialog without a title.

It seems I can't set a custom background to Alert Dialog.

@jul It the topic I mentioned there are solutions for Dialog class also. See replies with requestWindowFeature(Window.FEATURE_NO_TITLE); code.
