title: Fragment - replace container, if id is not unique
body: <p>I have a layout that has two views with the same id. If I want to find the view I just call <code>parentView1.findViewById(R.id.content)</code> or <code>parentView2.findViewById(R.id.content)</code> to get the correct view.</p>
  
  <p>If I want to replace a container with a fragment, can I somehow define which one I want to be replaced?</p>
