title: How to use ColorDrawable with ImageView?
body: <p>I have a layout with an ImageView defined like:</p>
  
  <pre><code>&lt;ImageView
    android:layout_width="45dip"
    android:layout_height="45dip"
    android:scaleType="fitXY" /&gt;
  </code></pre>
  
  <p>now I just want to set the imageview to be a static color, like red or green. I'm trying:</p>
  
  <pre><code>ColorDrawable cd = new ColorDrawable("FF0000");
  cd.setAlpha(255);
  ImageView iv = ...;
  iv.setImageDrawable(cd);
  </code></pre>
  
  <p>the imageview is just empty though, no color. The 45dip space is being used up though. What do I need to do to get the color to be rendered?</p>
  
  <p>Thanks</p>
