    <p>The issue of many fragments in one activity has been covered here before, but I cannot seem to find a solution for my positioning problem.</p> <p>I want a horizontal scroll bar on top of the screen and under it a custom ListFragment. The code I am posting below puts up the scroll bar and then the ListFragment overwrites it. When I try to modify the hosting FrameLayout to have two FrameLayouts I get runtime errors. </p> <p>Simply, How can I position the listFragment under the scrollbar?</p> <pre><code> public class GoogleNewsMainActivity extends FragmentActivity{ public static Context c; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); c=this; setContentView(R.layout.activity_fragment); /* FragmentManager fm = getSupportFragmentManager(); Fragment fragment = fm.findFragmentById(R.id.fragmentContainer); if (fragment == null) { Scroll_Menu_Fragment scrollFragment = new Scroll_Menu_Fragment(); fm.beginTransaction() .add(R.id.fragmentContainer, scrollFragment) .commit(); GoogleNewsMainFragment f = new GoogleNewsMainFragment(); fm.beginTransaction() .add(R.id.fragmentContainer, f) .commit(); } */ } } </code></pre> <p>Here is the scroll bar fragment:</p> <pre><code> public class Scroll_Menu_Fragment extends Fragment { @Override public void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // TODO Auto-generated method stub return inflater.inflate(R.layout.scrollbar_fragment, container, false); } @Override public void onPause() { // TODO Auto-generated method stub super.onPause(); } } </code></pre> <p>This is the ListFragment</p> <pre><code> public class GoogleNewsMainFragment extends ListFragment implements LoaderCallbacks&lt;Cursor&gt; { private static final String COLUMN_ID = "id"; public final static String NEWSFROMSERVICE = "NEWSFROMSERVICE"; static ImageView thumbnail; static String mSectionSelected; private NewsCursor mCursor; private ListView lv; private NewsCursorAdapter adapter; public static final String ID = "id"; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setRetainInstance(true); setHasOptionsMenu(true); mSectionSelected = ""; // until they select one getLoaderManager().initLoader(0, null, this); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View v = inflater.inflate(R.layout.fragment_google_news_main, container, false); getActivity().setTitle(R.string.news_list_title); return v; } </code></pre> <p>And finally the hosting layout</p> <pre><code> &lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/fragmentContainer" android:baselineAligned="false" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" &gt; &lt;fragment android:id="@+id/scrollFragment" android:layout_width="fill_parent" android:layout_weight="10" android:layout_height="wrap_content" android:layout_marginTop="10dp" class="com.gilchrist.android.googlenews.Scroll_Menu_Fragment" &gt;&lt;/fragment&gt; &lt;fragment android:id="@+id/listFragment" android:layout_width="fill_parent" android:layout_weight="90" android:layout_height="wrap_content" android:layout_marginTop="10dp" class="com.gilchrist.android.googlenews.GoogleNewsMainFragment" &gt;&lt;/fragment&gt; &lt;/LinearLayout&gt; </code></pre>

    2. COI changed the code that was originally posted and put the fragments in the activity layout - as suggested by someone in the comment above. the idea is to have the scrollview along the top of the screen and the remainder of the screen taken up by a listFragment. Same problem as I had when I tried to do this in runtime. The scroll bar appears at the top of the screen and then the listfragment takes up the entire screen and overwrites the scrollbar. How do you position the two fragments one above the other???

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
