android - ListView Item Selected State not working

So I have a ListView and I want to change the color of each items background and text. This ListView is inside a ListFragment. My code inflates the layout in the onCreateView and inflates the layout of each item in the newView.

The android:state_pressed="true" is working fine, whenever I press in one item the background changes to that color. But when selecting an item neither the bg color or text color changes, even though I've defined an item with android:state_selected="true" in the selector.

Edit: I'm using SDK level 11 (Android 3.0) and a Motorola Xoom.

The list fragment layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical">
    <ListView
        android:id="@android:id/list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"/>
</LinearLayout>

The list item layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:padding="25dp"
    android:background="@drawable/list_item_bg_selector">
    <TextView android:id="@+id/form_title"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textSize="@dimen/text_size_xlarge"
        android:textStyle="bold"
        android:textColor="@drawable/list_item_text_selector" />
    <TextView android:id="@+id/form_subtitle"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textSize="@dimen/text_size_medium"
        android:textStyle="normal"
        android:layout_marginTop="5dp"
        android:textColor="@drawable/list_item_text_selector" />
</LinearLayout>

The background selector:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item 
        android:state_pressed="true"
        android:drawable="@color/white" />
    <item
        android:state_selected="true"
        android:drawable="@drawable/list_item_bg_selected" />
    <item 
        android:drawable="@color/list_bg" />
</selector>

The text selector:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:state_selected="true"
        android:drawable="@color/white" />
    <item 
        android:drawable="@color/list_text_blue" />
</selector>

The answer is to use the android:state_activated="true" state, instead of the "selected" state. More on this here: ListFragment Item Selected Background
