title: How to update the ListView of a Fragment from another Fragment?
body: <p>How can I communicate a <code>listview</code> of a <code>ListFragment</code> after an event of a <code>Fragment</code> inside another <code>Fragment</code>?</p>
  
  <p>In the <code>ListFragment</code> (fragment A) I have a method to refresh the <code>ListView</code>. But also, I need to refresh it after a click of a <code>Button</code> inside a <code>Fragment</code>, wich is child of another <code>Fragment</code> (fragment b)</p>
  
  <p>Its like <code>Fragment</code> A (listFragment) | <code>Fragment</code> B (detailview) 
                                      (fragment C - child fragment of B)</p>
  
  <p>How can I do it?</p>
