带自己的布局的CheckBoxPreference

Question

我有一些PreferenceCheckBoxes的PreferenceScreen。我想更改标题和摘要的textColor和textSize，并勾选和取消选中CheckBox的图像。所以我使用android:layout来改变这个属性。

我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>  

冠军ID @+android:id/title和总结与@+android:id/summary都呈现正确的价值观。但是，尽管缺省值和编号为@+android:id/checkbox的复选框无法正常工作。它没有显示正确的值，我无法更改保存在首选项中的值。 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），只需触摸此复选框即可更改复选框的值。 如何以正确的方式为所有功能制作CheckBoxPreference的布局？

尝试以此为preference_checkbox.xml
