title: Stacked ActionBar tab bar not filling parent
body: <p>I'm creating Action Bar navigation tabs, but when the Action Bar is stacked the tabs are not getting the whole width space. I have a foto to illustrate it.</p>

  <p>Is possible, in this case, giving to each tab 50% of the screen width?</p>
  
  <p>Thank you</p>
  
  <p>I'm editing to say that it's not a Sherlock Action Bar. And I'm working in a Samsung Galaxy Note 10.1 and in a Nexus 7. And now, testing it in the Nexus, I noticed that it's behaviour is different. Another screenshot:</p>
