帶自己的佈局的CheckBoxPreference

Question

我有一些PreferenceCheckBoxes的PreferenceScreen。我想更改標題和摘要的textColor和textSize，並勾選和取消選中CheckBox的圖像。所以我使用android:layout來改變這個屬性。

我ChceckBoxPreference：

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

當我使用android:widgetLayout它看起來很奇怪。這是我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>  

冠軍ID @+android:id/title和總結與@+android:id/summary都呈現正確的價值觀。但是，儘管缺省值和編號爲@+android:id/checkbox的複選框無法正常工作。它沒有顯示正確的值，我無法更改保存在首選項中的值。 不使用任何佈局，我可以通過觸摸整個CheckBoxPreference來更改複選框的值。但現在（使用我的佈局），只需觸摸此複選框即可更改複選框的值。 如何以正確的方式爲所有功能製作CheckBoxPreference的佈局？

嘗試以此爲preference_checkbox.xml
