title: ListView Selector not working with ListViewItem's background set
body: <p>I have a <code>ListView</code> that has a selector set with just a solid color.  </p>
  
  <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"&gt;
  &lt;LinearLayout
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"
      android:layout_alignParentTop="true"
      android:id="@+id/assignmentSelectedItem" /&gt;
  &lt;ListView
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"
      android:id="@+id/assignmentsListView"
      android:layout_marginLeft="2dp"
      android:layout_marginRight="2dp"
      android:listSelector="@drawable/assignment_list_selector" /&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>assignment_list_selector.xml -</p>
  
  <pre><code>&lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;
   &lt;item android:state_pressed="true"
      android:drawable="@android:color/white" /&gt;
   &lt;item android:drawable="@android:color/transparent"/&gt;
  &lt;/selector&gt;
  </code></pre>
  
  <p>In the <code>ListView.Adapter</code> for my list, I have items that have their view's background set to a specific color.  My question would be is that why the selector is not working at all in displaying a selected color for my list view?  If so, any suggestion of a work around with allowing me to still set the view's background color.</p>
