My checkbox does not appear in my CheckedTextView
<p>Here is how I setup my checked text view. How come no check box appeared?</p>

<p>I also added this but it had not effect:
        listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);</p>

<pre><code> &lt;CheckedTextView
 android:id="@+id/ctv_checktext"
 android:layout_width="fill_parent"
 android:paddingLeft="2px"
 android:paddingRight="2px"
 android:paddingTop="2px"
 android:layout_height="wrap_content"
 /&gt;
</code></pre>
