    <p>This type of behavior is too dynamic to define in XML, but it's easy enough to accomplish with a custom container view. I'm making a couple of assumptions about your application, primarily that the root layout of the Activity only has two children (the <code>ListView</code> and the footer view). Based on that, the following is a custom <code>LinearLayout</code> which will give you what you need:</p> <pre><code>public class ComboLinearLayout extends LinearLayout { public ComboLinearLayout(Context context) { super(context); } public ComboLinearLayout(Context context, AttributeSet attrs) { super(context, attrs); } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { //We're cheating a bit here, letting the framework measure us first super.onMeasure(widthMeasureSpec, heightMeasureSpec); //Impose a maximum height on the first child View child = getChildAt(0); int newHeightSpec = MeasureSpec.makeMeasureSpec(getMeasuredHeight() / 2, MeasureSpec.EXACTLY); if (child.getMeasuredHeight() &gt; (getMeasuredHeight() / 2)) { measureChild(child, widthMeasureSpec, newHeightSpec); } //Optional, make the second child always half our height child = getChildAt(1); measureChild(child, widthMeasureSpec, newHeightSpec); } } </code></pre> <p>Then you can apply this in your Activity layout like so:</p> <pre><code>&lt;com.example.myapplication.ComboLinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"&gt; &lt;ListView android:id="@+id/list" android:layout_width="match_parent" android:layout_height="wrap_content"/&gt; &lt;TextView android:layout_width="match_parent" android:layout_height="match_parent" android:text="Hi Mom!" android:background="#0A0"/&gt; &lt;/com.example.myapplication.ComboLinearLayout&gt; </code></pre> <p>The net effect of the container code is that it fixes the measured height of the <code>ListView</code> to exactly half the container height if and only if it measures itself larger than that. Otherwise, it allows the <code>ListView</code> to be smaller.</p> <p>There's a secondary trick I added in case you needed it, which is an optional block of code that forces the footer view to always be half the screen height. If you are setting the footer view to a fixed height in XML, you can probably remove that second section from <code>onMeasure()</code>. If you use that code, it will work best if the footer view is set to <code>match_parent</code> in XML.</p>

    1. COWow! Thank you for this brilliant effort. I'll accept your answer soon, I want to wait a bit if someone else wants to pitch in.

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.
