复选框中的自定义复选框首选项 - 摘要打开和摘要

Question

我想稍微更改一下默认复选框首选项布局。我使用其他类似问题的答案，但仍然有一件事不起作用。

我有：

<CheckBoxPreference
 android:key="@string/pref_acceptableads"
 android:summaryOff="@string/pref_acceptableads_summary_off"
 android:summaryOn="@string/pref_acceptableads_summary_on"
 android:title="@string/pref_acceptableads_title"
 android:widgetLayout="@layout/checkbox_layout" />

和：

<!-- Layout for a Preference in a PreferenceActivity. The Preference is able

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"
android:orientation="horizontal" >
<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" />
<CheckBox
        android:id="@+id/checkbox"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#FFFFFF"/>        
</LinearLayout>

不幸的是，以这种方式，我的摘要和摘要不起作用。没有任何反应，但复选框中的"勾号"出现。当我使用图像而不是复选框时，它工作正常 - 单击图像会导致摘要更改。为什么它不适用于复选框？我应该怎么做才能恢复默认行为？

有必要添加行：

android:focusable="false"
android:clickable="false"

到自定义布局 XML 文件中的复选框项。
