title: Easy way of implemetning layers in fragments?
body: <p>The Activity class had a method called <code>addContentView()</code> that could be used to easily add an additional view layer.  I'd like to create my own <code>BaseFragment</code> class that has a method similar to <code>addContentView()</code>.  Is there an easy way to accomplish this with minimal code?  It'd be nice if I could rely on <code>Fragment.getView()</code> always being a <code>NoSaveStateFrameLayout</code> since I could just use that, but I'm guessing this could possibly change with different implementations of Android.</p>
  
  <p>I know I could just create a custom layout with a <code>FrameLayout</code> as the root but ideally I'd like the solution to be a re-usable framework, not specific to a specific <code>Fragment</code> class.</p>
