Answer 1

You can override OnCreate Method:

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = super.onCreateView(inflater, container, savedInstanceState);
        view.setBackgroundColor(getResources().getColor(<COLOR>));
        return view;
    }

Or you can enter the following in styles.xml

<style name="PreferenceTheme" parent="@style/Theme.AppCompat.Light.DarkActionBar">
        <item name="preferenceTheme">@style/PreferenceThemeOverlay</item>
        <item name="android:background">@android:color/white</item>
    </style>

Answer 2

Just extend AppTheme and use colorBackground attribute

<style name="PreferenceTheme" parent="@style/AppTheme">
    <item name="android:colorBackground">@color/colorBackground</item>
</style>
