    <p>Apparently as stated <a href="https://stackoverflow.com/a/13351391/281545">here</a> it is not possible.</p> <p>What I did was altogether drop the "root layout" (see <code>battery_details.xml</code>). So I create a fragment layout for my MonitorActivity :</p> <pre><code>public class MonitorActivity extends FragmentActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_monitor); } } </code></pre> <p>where the layout is :</p> <pre><code>&lt;!-- activity_monitor.xml --&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:baselineAligned="false" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".MonitorActivity" &gt; &lt;fragment android:name="di.k23b.hw3.fragments.MonitorDetailsFragment" android:id="@+id/monitor_details" android:layout_weight="1" android:layout_width="0dp" android:layout_height="match_parent" /&gt; &lt;fragment android:name="di.k23b.hw3.fragments.MonitorPrefsFragment" android:id="@+id/monitor_preferences" android:layout_weight="2" android:layout_width="0dp" android:layout_height="match_parent" /&gt; &lt;/LinearLayout&gt; </code></pre> <p>and in MonitorDetailsFragment class :</p> <pre><code>public class MonitorDetailsFragment extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { return inflater.inflate(R.layout.battery_details, container, false); // NEVER TRUE ! } } </code></pre> <p>where the <code>battery_details.xml</code> (created in <code>res/layout</code>) :</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/batteryTextHealth" android:layout_width="120dp" android:layout_height="wrap_content" android:ems="10" android:text="BATTERRRYYY" android:textIsSelectable="true" &gt; &lt;/TextView&gt; </code></pre> <p>Works. So maybe you can edit the layout you use the fragments, add the <code>&lt;LinearLayout&gt;</code> there and just put the elements of the <code>&lt;LinearLayout&gt;</code> directly into the layout you use in the <code>OnCreateView</code> - dropping the merge tags</p>

Guidance
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.
