android - HoloEverywhere + ListPreference = 崩溃

Question

我一直在努力让 ListPreference 与 HoloEverywhere 一起使用。 我在 XML 文件中定义了我的设置。我对属性使用了 Holo 命名空间。与首选项相关的所有内容都使用 org.holoeverywhere 包中的类，因此问题出在其他地方。

当我单击应用程序中的 ListPreference 时，会出现问题。该首选项应打开一个对话框，其中包含可供选择的选项。相反，它崩溃了，给了我以下堆栈跟踪:

我目前正在使用 PreferenceFragment，但是当我尝试使用 addPreferencesFromResource(int) 直接在 PreferenceActivity 中添加首选项时，会发生完全相同的情况)。

列表首选项 (XML) 本身:

    <ListPreference
        holo:defaultValue="false"
        holo:dialogTitle="@string/sett_inet_access_dial"
        holo:entries="@array/sett_inet_access_names"
        holo:entryValues="@array/sett_inet_access_values"
        holo:key="@string/keysett_inet_access"
        holo:summary="@string/sett_inet_access_summ"
        holo:title="@string/sett_inet_access_name" />

我还想补充一点，我的所有 ListPreference 项目(我有多个)都会发生这种情况。

好的。我已经弄清楚了。

事实证明。 HoloEverywhere 1.4.0 中存在一个错误。 该问题已被报告并修复: https://github.com/ChristopheVersieux/HoloEverywhere/issues/203

不幸的是，该修复尚未合并到 HE GitHub 项目的主分支中。它平静地坐在开发分支上，很可能正在等待下一个版本......

因此，如果您遇到与我相同的问题，那么您应该使用 dev 分支，或者 fork 存储库并选择 THIS提交到您的主分支。

样式未正确应用于对话框的问题仍然存在。
