title: Meaning of "No label views point to this text field" warning message
body: <p>What is the meaning of this warning?   </p>
  
  <blockquote>
    <p>No label views point to this text field with an android:labelFor="@
    id/@ id/editText1" attribute</p>
  </blockquote>
  
  <p>Note that the double id (<code>@id/@id</code>) is a problem <strong>with the error message text</strong> and does not reflect the XML content (which is the correct syntax).</p>
