XML layout not cooperating
<p>I'm having trouble trying to use a list in my activity.  My XML for res/layout/main.xml is as follows:</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    &gt;
&lt;TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"
    /&gt;
&lt;ListView android:id="@+id/ListView01" android:layout_width="wrap_content" android:layout_height="wrap_content"&gt;
&lt;TwoLineListItem android:id="@+id/TwoLineListItem01" android:layout_width="wrap_content" android:layout_height="wrap_content"&gt;
&lt;TextView android:id="@android:id/text1"
        android:layout_marginTop="1dip"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="15sp"
        android:textStyle="bold"
        android:text="@string/text1" /&gt;
&lt;TextView android:id="@android:id/text2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@android:id/text1"
        android:layout_alignLeft="@android:id/text1"
        android:paddingBottom="4dip"
        android:includeFontPadding="false"
        android:textSize="15sp"
        android:textStyle="normal"
        android:text="@string/text2" /&gt;
&lt;/TwoLineListItem&gt;
&lt;/ListView&gt;
&lt;/LinearLayout&gt;
</code></pre>

<p>Once I try to run it, however, my app just "quits unexpectedly".  It's got to be something wrong with the XML, since the activity is just the default <code>setContentView(R.layout.main);</code>  Please tell me what I'm doing wrong.</p>
