title: Public class multiple extends and implements
body: <p>So... I use this public class right now and it works fine (MainActivity.java) For my tabs in my app. But I want to do something with the tabs and need to use buttons and textViews and other stuff.
  But I cant because I need to use two extends and two implements for them both to work.</p>
  
  <pre><code>public class MainActivity extends ActionBarActivity implements TabListener 
  </code></pre>
  
  <p>How it should look/work, how it need to look and work</p>
  
  <pre><code>public class MainActivity extends ActionBarActivity, Activity implements TabListener, OnClickListener
  </code></pre>
  
  <p>Any fix or knowledge in how to fix this? (I use Android Eclipse)</p>
