我很难找到Android API中提供的MultiSelectListPreference的一个很好的例子.我看过很多对这个博客的引用,这就是我想要的最终结果,我不想为我想要实现的每个多选择首选项创建一个类.最后,我希望看到一个简单的多选对话框(我将动态填充值)的首选项xml,以及调用addPreferencesFromResource(R.xml.preferences);

目前,我有:

<MultiSelectListPreference
    android:defaultValue=""
    android:enabled="true"
    android:entries="@array/pref_default_entries"
    android:entryValues="@array/pref_default_values"
    android:key="TargetList"
    android:persistent="true"
    android:summary="@string/TargetSummary"
    android:title="@string/TargetTitle" />

当我尝试在我的Activities onCreate调用中调用addPreferencesFromResource时,我收到以下错误:
