title: Changing android actionbar background not working
body: <pre><code>ActionBar actionBar = getSupportActionBar();
  actionBar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#330000ff")));
  actionBar.setStackedBackgroundDrawable(new ColorDrawable(Color.parseColor("#550000ff")));
  </code></pre>
  
  <p>I'm trying to change my actionbar and the tab backgrounds, using the code above, the actionbar background changes perfectly but the tab backgrounds doesn't change at all, I'd like to know if this is due to the fact that I use supportActionBar or not, if anyone has a solution, Thanks!</p>
