Android应用程序通过设置默认值崩溃

我尝试这样做：

PreferenceManager.setDefaultValues(this, R.xml.defaults, false);

这

SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this); 
PreferenceManager.setDefaultValues(this, R.xml.defaults, false);

但它总是崩溃。

这里我RES/XML/defaults.xml中

<?xml version="1.0" encoding="utf-8"?> 
<resources> 
    <string name="programTitles">["x", "a", "b", "c", "d", "e"]</string> 
    <string name="programSubs">["", "as", "bs", "cs", "ds", "es"]</string> 
</resources>

的logcat：

对我来说，这似乎是 “资源” 是一个错误的标签或类似的东西。这是吗？我需要哪个标签？

哪里是你的logcat然后???? – 2014-10-09 10:57:53

字符串资源是一个数组？ – RvdK 2014-10-09 10:59:45

' [“x”，“a”，“b”，“c”，“d”，“e”]这是**不是**字符串数组。 – 2014-10-09 11:01:17

从资源删除<resources>标签/ XML/defaults.xml中

该文件应该是这样的：

<?xml version="1.0" encoding="utf-8"?>

<PreferenceCategory 
    android:title="PreferenceCategory A"> 

    <CheckBoxPreference 
     android:key="checkbox_preference" 
     android:title="title_checkbox_preference" 
     android:summary="summary_checkbox_preference" /> 

</PreferenceCategory> 

<PreferenceCategory 
    android:title="PreferenceCategory B"> 

    <EditTextPreference 
     android:key="edittext_preference" 
     android:title="title_edittext_preference" 
     android:summary="summary_edittext_preference" 
     android:dialogTitle="dialog_title_edittext_preference" /> 

</PreferenceCategory>
