Body
I changed my onCreate() in my ItemListFragment to: <pre><code>@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Log.d("debug","Hallo in ItemListFragment"); //show ActionBar setHasOptionsMenu(true); //get reference to activity myApp = getActivity().getApplication(); //check if intent from ItemListActivity is null Bundle be = getActivity().getIntent().getExtras(); if (be == null){ //if null read local feed feed = ReadFeed(fileName); Log.d("debug", "Lese Feed lokal :"+feed); }else{ //else get extras from the intent feed = (RSSFeed) getActivity().getIntent().getExtras().get("feed"); Log.d("debug", "Intent von ItemListActivity an ItemListFragment vorhanden"); } } </code></pre> and added this function: <pre><code>/** * Method to read the feed from the file **/ private RSSFeed ReadFeed(String fName) { FileInputStream fIn = null; ObjectInputStream isr = null; RSSFeed _feed = null; File feedFile = getActivity().getBaseContext().getFileStreamPath(fileName); if (!feedFile.exists()) return null; try { fIn = getActivity().openFileInput(fName); isr = new ObjectInputStream(fIn); _feed = (RSSFeed) isr.readObject(); } catch (Exception e) { e.printStackTrace(); } finally { try { fIn.close(); } catch (IOException e) { e.printStackTrace(); } } return _feed; } </code></pre> Of course I use a similar write method in my Main Activity where I parse my XML feed the first time. In the ItemDetailFragment I removed every code for ActionBar navigation and works fine now!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
