RSS entry content not showing

[ghost]

After I updated the node names for my RSS feed, I get the entries in list view.
But selecting one entry only shows an empty details page.

Checking the sources, I found that the item_id is passed to a new ArticleDetailFragment activity

detailIntent.putExtra(ArticleDetailFragment.ARG_ITEM_ID, id);

which creates a new fragment setting the item_id as String

arguments.putString(ArticleDetailFragment.ARG_ITEM_ID,getIntent().getStringExtra(ArticleDetailFragment.ARG_ITEM_ID));

but the fragment only sets displayedArticle if the Article.KEY is set and I can't find where it handles the item_id.
Am I wrong? Solution for this?

I did the following:
In ArticleListActivity:

        //load article details to main panel
        Bundle arguments = new Bundle();
        arguments.putSerializable (Article.KEY, selected);

        if (mTwoPane) {
            ArticleDetailFragment fragment = new ArticleDetailFragment();

            fragment.setArguments(arguments);

            getSupportFragmentManager().beginTransaction()
                    .replace(R.id.article_detail_container, fragment)
                    .commit();

        } else {
            Intent detailIntent = new Intent(this, ArticleDetailActivity.class);

            detailIntent.putExtra("arguments", arguments);

            startActivity(detailIntent);
        }

in ArticleDetailActivity:

        if (savedInstanceState == null) {
            Bundle arguments = getIntent().getBundleExtra("arguments");
            ArticleDetailFragment fragment = new ArticleDetailFragment();

            fragment.setArguments(arguments);

            getSupportFragmentManager().beginTransaction()
                    .add(R.id.article_detail_container, fragment)
                    .commit();
        }

Dear eRGoon,
your code create another issue in ArticleDetailFragment pointing out a NullPointerException on line:

ArticleListFragment fragment = (ArticleListFragment) getActivity().getSupportFragmentManager().findFragmentById(R.id.article_list);

Any idea to solve this?

Hi BeDave,

are you sure about this? I cannot find such line in ArticleDetailFragment.

[davidedesio]

Yep, i'm pretty sure about this.
Search for "onOptionsItemSelected(MenuItem item)" method and look in
"else if (id == R.id.actionbar_markunread)" statement.
It controls the behavior of mark as unread button in article detail
view.

Indeed, the fragment cannot be found. If I just get the fragment it already returns null.

ArticleListFragment fragment = (ArticleListFragment) getActivity().getSupportFragmentManager().findFragmentById(R.id.article_list);

However, it only does so when running in a one pane layout. If you are on a tablet, it doesn't happen when you mark it as unread. Unfortunately, I've not been able to fix it, so my solution is removing the menu item on one-pane layouts using this:
In ArticleListActivity:

    private static boolean mTwoPane; // change to static

    public static boolean isTwoPane() {
        return mTwoPane;
    }

In ArticleDetailFragment:

    @Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        inflater.inflate(R.menu.detailmenu, menu);
        if (!ArticleListActivity.isTwoPane()) { // add this
            menu.removeItem(R.id.actionbar_markunread);
        }
    }

    // if you want extra security

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        int id = item.getItemId();
        if (id == R.id.actionbar_saveoffline) {
            Toast.makeText(getActivity().getApplicationContext(),
                    R.string.saved_for_offline, Toast.LENGTH_LONG).show();
            return true;
        } else if (id == R.id.actionbar_markunread) {
            db.openToWrite();
            db.markAsUnread(displayedArticle.getGuid());
            db.close();
            displayedArticle.setRead(false);
            try {
                ArticleListAdapter adapter = (ArticleListAdapter) ((ArticleListFragment) getActivity()
                        .getSupportFragmentManager().findFragmentById(
                                R.id.article_list)).getListAdapter();
                adapter.notifyDataSetChanged();
            } catch (NullPointerException e) {
            }
            return true;
        } else {
            return super.onOptionsItemSelected(item);
        }
    }
