How can I refresh a fragment list from an action bar button with RSS Feed information?
<p>I'm doing my first app, a RSS Feed application, for learning the multiple technologies associated, like xml, parsing, connecting to the internet, getting the information, processing it, etc.</p>

<p>I've decided to use the newest Android elements, such as the Action Bar and Fragments. So I've done an action bar with a few options, like Refresh (which refreshes the RSS list), Preferences, About and Exit. The main issue is with the Refresh.</p>

<p>I'm pressing Refresh and the option creates an object which will get the XML, which should return the information for the newsList Fragment. But I can't pass the information to the fragment, but I also can't Toast the xml information to the screen, so I cannot test if I'm getting everything correctly.</p>

<p>My programming background is not in Java, I'm used to Web Developing (PHP) and scripting (Shell) so I guess I'm missing some basic stuff, which I apologize in advance.</p>

<p>Can anybody at least give me some hints, in order for me to know what to search and get back in the right path?</p>

<p>Thanks a lot!</p>
