title: Fragment transaction animation: slide in and slide out
body: <p>I've check some tutorials for animate transaction between fragments. I've used this method for animation and it works:</p>
  <pre><code>fragmentTransaction.setCustomAnimations(android.R.anim.slide_in_left,
                  android.R.anim.slide_out_right);
  </code></pre>
  <p>But I want to invert this animation: old fragment slide out to the left, and new fragment slide in to the right, but no value of <code>R.anim</code> file seems to be useful for my scope.</p>
  <p>How can I do it?</p>
