How do I create marginless button bar in Android

Question

I want my application to have button bar at the bottom, that is similar to this one (Motorola Defy+):

bottom button bar

How can this be achieved? I've tried ButtonBar style with regular buttons in it, but they always have margin in this case.

Here I see zero marging and padding for the bar and zero marging and non-zero padding for buttons — Gangnus, Jan 21 '12 at 21:52

By code:

Make the bar LinearLayout horizontal. Let´s say its name in code will be bbll.

LinearLayout.LayoutParams params = bbll.LayoutParams();
params.leftMargin=0;
params.rightMargin=0;
... or params.setMargins(0, 0, 0, 0);
bbll.setLayoutParams(params);

By layout simply set each margin to 0. That's all. If you have done it and it won't work, put the code here, please.

But you should set bbll.setPadding(0,0,0,0) , too. Or you'll see empty space between the bar (that is invisible) and the buttons. aqs has a good thought.
