Question

您好我想问为什么我的MultiSelectListPreference在这里收到错误是我的代码

XML＆GT;的prefs.xml

<MultiSelectListPreference
    android:title="MultiSelectList"
    android:key="multi"
    android:summary="List to choose from"
    android:entries="@array/MultiSelectList"
    android:entryValues="@array/mlValues"
    android:defaultValue="@array/empty_array"
    >
</MultiSelectListPreference>

值＆GT; array.xml

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

<string-array name="MultiSelectList">
    <item>Option1</item>
    <item>Option2</item>
    <item>Option3</item>
    <item>Option4</item> 
</string-array>

<string-array name="mlValues">
    <item>1</item>
    <item>2</item>
    <item>3</item>
    <item>4</item>
</string-array>

<string-array name="empty_array">
    <item>0</item>
    <item>0</item>
    <item>0</item>
    <item>0</item>
</string-array>

</resources>

但是当我将MultiSelectListPreference更改为ListPreference它工作正常请帮我解决这个问题

这是我的 logcat
