title: Android EditText.setError() yields invisible error text
body: <p>I have a very simple EditText, as follows:</p>
  
  <pre><code>&lt;EditText
       android:id="@+id/myedit"
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"
       android:singleLine="true"
       android:maxLength="32"/&gt;
  </code></pre>
  
  <p>In some validation code, I use Android's <code>EditText.setError()</code> to show any validation errors. This works fine in OS 2.x but not on an OS 3.x device (Xoom) -- on the Xoom you can see the outline of the error popup but you cannot see the error text.  </p>
  
  <p>I'm guessing that the text is there, but it is invisible. How do I make it visible? I don't see an <code>android:textColor</code> that would relate to error text.</p>
  
  <p>Also, if the text is indeed invisible, then any ideas why 2.x behaves differently to 3.x -- seems like this would cause backward-compatibility problems.</p>
  
  <p>Thanks.</p>
