title: styling tabs using styles.xml
body: <p>I have a row of 5 tabs at the bottom of my app.  The problem is the text is cut off on some of them. I want to be able to have the text in each tab stack on top of each other instead of following along horizontally aswell as move the text into the center of the tab instead of sitting at the bottom.</p>
  
  <p>I have created a styles.xml file and have altered the text size but I am not sure how to add the requirments I stated above to it.  Can anyone help?</p>
  
  <p>Thanks</p>
