You will have to set android:layout_marginRight="0dip" and you will have to remove the padding with android:paddingRight="0dip" for the other button this has to be changed to the left values. I guess you forgot that every android element has generally a padding added to it by default. This is generally a good idea, but if you want to remove it, this is the way.
