Android 添加另一个EditTextPreference时使用FC

我有一个有效的XML首选项，但当我将其添加到另一个EditTextPreference时，首选项活动将继续：

<PreferenceCategory android:title="Prochain vidange">
<EditTextPreference
        android:name="Prochain vidange"
        android:summary="Prochain vidange:"
        android:defaultValue=""
        android:numeric="integer|decimal"
        android:title="Prochain vidange:"
        android:key="proch" />
</PreferenceCategory>

这个奇怪的FC有什么问题？ 多谢各位

示例阵列：

<?xml version="1.0" encoding="utf-8"?>
<resources>
<string-array name="notif">
 <item>Chaque jour</item>
 <item>Chaque semaine</item>
 <item>Chaque mois</item>
</string-array>

<string-array name="notif_return">
 <item>0</item>
 <item>1</item>
 <item>2</item>
 </string-array>
</resources>

是否将其中一个数组设置为整数数组？android:entries=@array/blah

有一个已知的错误，您必须为xml首选项使用字符串数组。对不起

您也可以将EditTextPreference设置为整型，但设置的默认值可以是字符串。

java.lang.ClassCastException:java.lang。Integer@Blundell：我不理解你，抱歉，请阅读我的答案：-并检查strings.xml或arrays.xmlcheck 08-16 14:23:15.639:ERROR/AndroidRuntime880:at carbonant.android.com.Vidange.onCreateVidange.java:45，对吗？我不擅长阅读日志，但你的错误应该在那里，不是吗？@Rob:addPreferencesFromResourceR.xml.vidange；我所有的数组都是字符串值和返回值。问题是我在添加first EditTextPreferenceProchProchProblem时遇到了FC问题，我的偏好混乱。但我始终无法为EditTextPreference设置值：。如果您还记得的话，我打开了一个主题。那么您是否尝试将默认值设置为0？查找它；。我选择另一种方法：EditTextPreference myEditTextPreference=EditTextPreference findPreferenceproch；myEditTextPreference.setTextz；
