    <p>Sorry if this redundant with the ton of questions/answers on inflate, but I could not get a solution to my problem.</p> <p>I have a compound view (LinearLayout) that has a fixed part defined in XML and additional functionalities in code. I want to dynamically add views to it.</p> <p>Here is the XML part (compound.xml):</p> <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/compoundView" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal" &gt; &lt;TextView android:id="@+id/myTextView" android:layout_width="110dp" android:layout_height="wrap_content" android:text="000" /&gt; &lt;/LinearLayout&gt; </code></pre> <p>I have defined in code a LinearLayout to refer to the XML:</p> <pre><code>public class CompoundControlClass extends LinearLayout { public CompoundControlClass (Context context) { super(context); LayoutInflater li; li = (LayoutInflater)getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); li.inflate(R.layout.compound_xml,*ROOT*, *ATTACH*); } public void addAView(){ Button dynBut = new Button(); // buttoin def+layout info stripped for brevity addView(dynBut); } } </code></pre> <p>I tried to programmatically add a view with addAView.</p> <p>If ROOT is null and ATTACH is false, I have the following hierarchy (per HierarchyViewer):</p> <ul> <li>CompoundControlClass>dynBut </li> </ul> <p>The original TextView in the XML is gone.</p> <p>If ROOT is this and ATTACH is true, I have the following hierarchy:</p> <ul> <li>CompoundControlClass>compoundView>myTextView</li> <li>CompoundControlClass>dynBut</li> </ul> <p>I would like to have </p> <ul> <li>CompoundControlClass>myTextView</li> <li>CompoundControlClass>dynBut</li> </ul> <p>where basically the code and XML are only one unique View. What have I grossly missed?</p> <h1>ANSWER BASED on feedback from D Yao ----------------------</h1> <p>The trick is to INCLUDE the compound component in the main layout instead of referencing it directly.</p> <p>activity_main.xml</p> <pre><code>&lt;RelativeLayout 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"&gt; &lt;include layout="@layout/comound" android:id="@+id/compoundView" android:layout_alignParentBottom="true" android:layout_width="fill_parent" android:layout_height="wrap_content"/&gt; &lt;/RelativeLayout&gt; </code></pre> <p>mainActivity.java</p> <pre><code>public class MainActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); CompoundControlClass c = (CompoundControlClass) this.findViewById(R.id.compoundView); c.addAView(this); } } </code></pre> <p>CompoundControlClass.java</p> <pre><code>public class CompoundControlClass extends LinearLayout { public CompoundControlClass(Context context) { super(context); } public CompoundControlClass(Context context, AttributeSet attrs) { super(context, attrs); } public CompoundControlClass(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } public void addAView(Context context){ ImageView iv = new ImageView(context); iv.setImageResource(R.drawable.airhorn); addView(iv); } } </code></pre> <p>compound.xml</p> <pre><code>&lt;com.sounddisplaymodule.CompoundControlClass xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/compoundView" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal" &gt; &lt;TextView android:layout_width="110dp" android:layout_height="wrap_content" android:gravity="right" android:textSize="40sp" android:textStyle="bold" android:text="0:00" /&gt; &lt;/com.sounddisplaymodule.CompoundControlClass&gt; </code></pre>

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.

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