Custom Android preferences background

Question

I'm currently trying to set custom background for preference screen. I've created PreferenceActivity

public class SettingsActivity extends PreferenceActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    addPreferencesFromResource(R.xml.preferences);
    PreferenceManager.setDefaultValues(this, R.xml.preferences, false);
}
}

Here are my Preference layout

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" 
    >
    <CheckBoxPreference 
        android:key="pref_Autoplay"
        android:title="@string/pref_Autoplay"
        android:summary="@string/pref_Autoplay_summ"
        android:defaultValue="false"/>
    <ListPreference 
        android:entryValues="@array/pref_Voice_values" 
        android:entries="@array/pref_Voice_entries" 
        android:key="pref_Voice" 
        android:summary="Choose male or female reader" 
        android:title="Readers voice" 
        android:defaultValue="female"/>


</PreferenceScreen>

As I read here to change background I need to create my own theme with style. Here it is:

<style name="PrefsTheme" parent="@android:style/Theme.Black.NoTitleBar">
        <item name="android:windowBackground">@drawable/prefs_bg</item>
        <item name="android:textColor">@color/prefs_bg</item>
        <item name="android:listViewStyle">@style/listViewPrefs</item>
    </style>

    <style name="listViewPrefs" parent="@android:style/Widget.ListView">
        <item name="android:background">@color/prefs_bg</item>
        <item name="android:cacheColorHint">@color/prefs_bg</item>
        <item name="android:textColor">@color/prefs_bg</item>
    </style>

All I need is to set some image background for preferences list. My image is @drawable/prefs_bg. When I set windowBackground to image and background to some color, preferences list background uses color instead of picture. But when I set background to @drawable/prefs_bg preferences list background appears with my picture and Radio Button dialog for my ListPreference item is also using image background.

Please help, how can I set image background for preferences list without affecting background of radio button dialog of some of the preferences item?

Ok. I've found how to solve my problem. It was my fault. To set Preference background only need

<item name="android:windowBackground">@drawable/prefs_bg</item>

This one was unnecessary:

<item name="android:background">@color/prefs_bg</item>
<item name="android:cacheColorHint">@color/prefs_bg</item>
