Android eclipse xml formatting issue

Hello i have a xml file which doesent seem to work, i am trying to reach it with a listpreference.

Here is the listpreference code:

<PreferenceCategory android:name="@string/yo_category">

<ListPreference
    android:title="YOYO"
    android:key="YOYOYO"
    android:summary="YODOBO"
    android:entries="@+arrays/yoyo"
    android:entryValues="@+arrays/yoyoValues"
></ListPreference>

</PreferenceCategory>  

And here is the xml file:

<string-array name="yoyo">
    <item>1 yoyo</item>
    <item>2 yoyos</item>
    <item>3 yoyos</item>
</string-array>
<string-array name="yoyoValues">
    <item>1</item>
    <item>2</item>
    <item>3</item>
</string-array>

And i cannot seem to find the issue here, i get no errors in eclipse but when i try to run it i cant see the items in the listpreference.

Thanks for any help!
