title: ImageView - have height match width?
body: <p>I have an imageview. I want its width to be fill_parent. I want its height to be whatever the width ends up being. For example:</p>
  
  <pre><code>&lt;ImageView
    android:layout_width="fill_parent"
    android:layout_height="whatever the width ends up being" /&gt;
  </code></pre>
  
  <p>Is something like that possible in a layout file without having to create my own view class?</p>
  
  <p>Thanks</p>
