如何在启用开关时更改SwitchPreference文本颜色？

<style name="SwitchPreferenceStyle" parent="@android:style/Preference">
    <item name="android:widgetLayout">@layout/custom_switch_preference</item>
</style>

<SwitchPreference
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+android:id/switchWidget"
    android:layout="@layout/preference_widget_switch"
    android:widgetLayout="@layout/preference_widget_switch"
    android:switchTextAppearance="@style/SwitchPreferenceTextAppearance"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:gravity="center_vertical"
    android:paddingStart="?android:attr/switchPreferencePaddingStart"
    android:paddingEnd="?android:attr/switchPreferencePaddingEnd"
    android:background="?android:attr/selectableItemBackground"
    android:clickable="true"
    android:focusable="true"
    android:clipToPadding="false"
    android:textColor="@color/switch_preference_text_color" />

<color name="switch_preference_text_color">#FF0000</color>

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
    <SwitchPreference
        android:key="switch_preference"
        android:title="Switch Preference"
        android:summary="This is a switch preference"
        android:defaultValue="false"
        android:switchPreferenceStyle="@style/SwitchPreferenceStyle" />
</PreferenceScreen>
