Android Button With No Padding

I am trying to use the open source antennapod application as a reference for building my android application. I am using ActionBarSherlock and want to create a button at the botto

Solution 1:

<Button
        android:id="@+id/butConfirm"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Search"
        android:background="@null"/>

This should do the trick!
