You need to provide a full reference to the class, including the package.

For instance,

<org.example.myapp.ExtendedWebView
    android:id="@+id/webview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
 />

If you did want them in the same class file, you could make it static and reference it in XML via: `` – Tom Leese Dec 30 '12 at 23:34

Solved for me by using this in my XML:

 <view
    class="com.example.MainActivity$MyWebView"
    android:id="@+id/web_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>
