No controls in emulator?
<p>I'm trying to run a very simple Android demo using the eclipse ADT.  The app compiles &amp; the emulator opens but no controls show up.  I have a title for the app, but the button &amp; text field do not display.  Any ideas?  I don't see any errors in the console.</p>

<pre><code> &lt;?xml version="1.0" encoding="utf-8"?&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:orientation="horizontal"&gt;
    &lt;EditText android:id="@+id/edit_message"
        android:layout_weight="1"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:hint="@string/edit_message" /&gt;
    &lt;Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/button_send" 
        android:onClick="sendMessage"/&gt;
&lt;/LinearLayout&gt;
</code></pre>
