Я пытаюсь заставить это работать: я в основном хочу два Recyclerviews в одном ViewPager. Я следовал этому уроку:http://android-java-development.blogspot.de/2012/05/system.html, но это не похоже на работу. Похоже, пейджер просмотра пуст, а вид переработчика не отображается.

Вот мой код компоновки:

<android.support.v4.widget.SwipeRefreshLayout
        android:id="@+id/pager_refresh_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingTop="@dimen/tab_height">

        <android.support.v4.view.ViewPager
            android:id="@+id/pager"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@color/accent"/>
    </android.support.v4.widget.SwipeRefreshLayout>

И мой PageAdapter:

public class NewsPagerAdapter extends PagerAdapter {
    private Context context;
    private Vector<RecyclerView> recyclerViewList;
    private String[] titles;

    public NewsPagerAdapter(Context context, int titlesId) {
        this.context = context;
        this.recyclerViewList = new Vector<>();

        setTitles(titlesId);
    }

    public void add(RecyclerView recyclerView) {
        recyclerViewList.add(recyclerView);
    }

    public RecyclerView.Adapter getAdapterForViewAtIndex(int index) {
        return recyclerViewList.get(index).getAdapter();
    }

    @Override
    public Object instantiateItem(ViewGroup container, int position) {
        container.addView(recyclerViewList.get(position),
                new RecyclerView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 100)
        );
        return container;
    }

    @Override
    public int getCount() {
        return recyclerViewList.size();
    }

    @Override
    public boolean isViewFromObject(View view, Object object) {
        return view.equals(object);
    }

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        container.removeView((View) object);
    }

    @Override
    public CharSequence getPageTitle(int position) {
        return titles[position];
    }

    public void setTitles(int titles) {
        this.titles = context.getResources().getStringArray(titles);
    }
}

И мой метод onCreatView:

GridLayoutManager layoutManager1 = new GridLayoutManager(getActivity(), getResources().getInteger(R.integer.news_column_count));

GridLayoutManager layoutManager2 = new GridLayoutManager(getActivity(), getResources().getInteger(R.integer.news_column_count));

RecyclerView listView1 = new RecyclerView(getActivity());
RecyclerView listView2 = new RecyclerView(getActivity());
listView1.setLayoutManager(layoutManager1);
listView2.setLayoutManager(layoutManager2);

NewsAdapter adapter1 = new NewsAdapter(getActivity(), null);
NewsAdapter adapter2 = new NewsAdapter(getActivity(), null);
adapter1.setOnItemClickListener(this);
adapter2.setOnItemClickListener(this);

listView1.setAdapter(adapter1);
listView2.setAdapter(adapter2);

newsPagerAdapter.add(listView1);
newsPagerAdapter.add(listView2);

newsViewPager.setAdapter(newsPagerAdapter);

Здесь я передаю курсор объект к адаптеру:

@Override
    public void onLoadFinished(Loader<Cursor> loader, Cursor data) {
        ((NewsAdapter) newsPagerAdapter.getAdapterForViewAtIndex(0)).swapCursor(data);
    }
