title: EditText hint doesn't show
body: <p>My <code>EditText</code> configured as follows won't show the hint: </p>
  
  <pre><code>&lt;EditText
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"
      android:gravity="right"
      android:hint="The hint..."
      android:scrollHorizontally="true"
      android:singleLine="true" /&gt;
  </code></pre>
  
  <p>It works if I set <code>android:gravity="left"</code> or if I remove <code>android:scrollHorizontally</code> and <code>android:singleLine</code> attributes, which is not desirable. Any suggestions?</p>
