复选框preference有自己的布局 [英] CheckBoxPreference with own layout

问题描述

我有preferenceScreen一些preferenceCheckBoxes。我想改变文字颜色和TEXTSIZE的标题和摘要以及对CheckBox图像检查和uncheckes。所以我使用机器人：布局来改变这种属性。

I have PreferenceScreen with some PreferenceCheckBoxes. I want to change the textColor and textSize for title and summary and the images for the CheckBox checked and uncheckes. So I am using android:layout to change this attributes.

我的ChceckBox preference：

My ChceckBoxPreference:

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

当我使用安卓widgetLayout 这看起来很奇怪。这是我的preference_checkbox.xml：

When I use android:widgetLayout it looks strange. And this is my 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>     

名称与编号 @ +安卓ID /标题及摘要与 @ +安卓ID /摘要是显示出正确的价值观。然而，尽管默认值和id 的复选框@ +安卓ID /复选框工作不正常。它没有显示正确的值，我不能更改保存在preferences值。 不使用任何布局，我可以在整个复选框preference通过触摸改变复选框的值。但现在（我的布局）我只能通过触摸在此复选框改变复选框的值。 我怎样才能使布局复选框preference以正确的方式与所有的功能？

Title with id @+android:id/title and summary with @+android:id/summary are showing correct values. However the checkbox despite of default value and id @+android:id/checkbox is not working properly. It isn't showing correct value and I can't change the value kept in preferences. Without using any layout, I can change value of checkbox by touch at the whole CheckBoxPreference. But now (with my layout) I can change value of checkbox only by touch on this checkbox. How can I make layout for CheckBoxPreference in properly way with all the functionalities?

试试这个为preference_checkbox.xml

Try this as preference_checkbox.xml
