title: Android: Why textView text attribute value is id?
body: <pre><code>&lt;TextView
      android:id="@+id/label"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:text="@+id/label"
      android:textSize="20px" &gt;
  &lt;/TextView&gt;
  </code></pre>
  
  <p>this is part code of ListActivity with custom Layout. So it can dynamically set value. Why android:text="@+id/label" ? Have a any other use?</p>
