I\'m trying to do something I do with activities, but within a fragment. What I do is using activities:

If I understand correctly, you don't want to the fragment to reload on each rotation. Instead you want to relayout the views and update them with information you already have.

public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    // Get a layout inflater (inflater from getActivity() or getSupportActivity() works as well)
    LayoutInflater inflater = (LayoutInflater) getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View newView = inflater.inflate(R.layout.frg.myFragment, null);
    // This just inflates the view but doesn't add it to any thing.
    // You need to add it to the root view of the fragment
    ViewGroup rootView = (ViewGroup) getView();
    // Remove all the existing views from the root view.
    // This is also a good place to recycle any resources you won't need anymore
    rootView.removeAllViews();
    rootView.addView(newView);
    // Viola, you have the new view setup
}

According to the documentation (getView()), getView() returns the same view that you returned from your onCreateView() but it does not. It actually return the parent of the view you returned in onCreateView() which is exactly what you need. getView() will return an instance of NoSaveStateFrameLayout, which is used specifically for Fragments as its root view.

Hope this helps.
