CheckBoxPreference具有自己的布局

Question

我有PreferenceScreen和一些PreferenceCheckBoxes.我想更改textColor和textSize的标题和摘要以及CheckBox的图像选中和取消选中.所以我android:layout用来改变这个属性.

我的ChceckBoxPreference:

<CheckBoxPreference
    android:layout="@layout/preference_checkbox"
    android:key="temp"
    android:title="@string/title"
    android:summary="@string/summary"
    android:defaultValue="true" 
/>

当我使用android:widgetLayout它看起来很奇怪.这是我的preference_checkbox.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="10dp"
>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent"
    android:layout_alignParentLeft="true"
    android:layout_marginLeft="10dp"
>
<TextView 
    android:id="@+android:id/title"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:textColor="@color/gray"
    android:textSize="20sp"     
    />
<TextView 
    android:id="@+android:id/summary"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:textColor="@color/gray"
    android:textSize="14sp"
    />
</LinearLayout>
<CheckBox
    android:id="@+android:id/checkbox"
    android:layout_width="wrap_content" 
    android:layout_height="fill_parent" 
    android:layout_alignParentRight="true"
    android:layout_marginRight="10dp"
/>  
</RelativeLayout>     

带有id @+android:id/title和摘要的标题@+android:id/summary显示正确的值.但是,尽管默认值和id的复选框@+android:id/checkbox无法正常工作.它没有显示正确的值,我无法更改首选项中保留的值.不使用任何布局,我可以通过触摸整个CheckBoxPreference来更改复选框的值.但现在(使用我的布局)我只能通过触摸此复选框来更改复选框的值.如何以正确的方式为所有功能制作CheckBoxPreference的布局？
