由于zenob说，这可以通过自定义布局来解决。在框架中定义preference布局被用在应用程序

As zenob said this can be solved by a custom layout. Preference layout defined in the framework is used in the application:

custom_ preferece_layout.xml

custom_preferece_layout.xml

<?xml version="1.0" encoding="utf-8"?>

<!-- Layout for a Preference in a PreferenceActivity. The Preference is able 
    to place a specific widget for its particular type in the "widget_frame" 
    layout. -->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" android:layout_height="wrap_content"
    android:minHeight="?android:attr/listPreferredItemHeight"
    android:gravity="center_vertical" android:paddingRight="?android:attr/scrollbarSize">

    <RelativeLayout android:layout_width="wrap_content"
        android:layout_height="wrap_content" android:layout_marginLeft="15dip"
        android:layout_marginRight="6dip" android:layout_marginTop="6dip"
        android:layout_marginBottom="6dip" android:layout_weight="1">

        <TextView android:id="@+android:id/title"
            android:layout_width="wrap_content" android:layout_height="wrap_content"
            android:singleLine="true" android:textAppearance="?android:attr/textAppearanceLarge"
            android:ellipsize="marquee" android:fadingEdge="horizontal"
            android:textColor="#FF0000" />

        <TextView android:id="@+android:id/summary"
            android:layout_width="wrap_content" android:layout_height="wrap_content"
            android:layout_below="@android:id/title" android:layout_alignLeft="@android:id/title"
            android:textAppearance="?android:attr/textAppearanceSmall"
            android:maxLines="4" />

    </RelativeLayout>

    <!-- Preference should place its actual preference widget here. -->
    <LinearLayout android:id="@+android:id/widget_frame"
        android:layout_width="wrap_content" android:layout_height="match_parent"
        android:gravity="center_vertical" android:orientation="vertical" />

</LinearLayout>

文字颜色属性被定义为在上述布局标题TextView的。使用此布局的复选框preference在preference XML。

textColor attribute is defined for title TextView in the above layout. Use this layout with the checkbox preference in preference xml.

我的preference.xml

mypreference.xml

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
    <CheckBoxPreference android:key="testcheckbox"
    android:title="Checkbox Title"
    android:summary="Checkbox Summary..."
    android:layout="@layout/custom_preference_layout"></CheckBoxPreference>
</PreferenceScreen>

复选框preference冠军将在自定义布局定义的颜色。

Checkbox preference title will have the color defined in the custom layout.
