HoloEverywhere + ListPreference =崩溃
HoloEverywhere + ListPreference =崩溃
提问于 2012-12-20 17:51:13
我一直在努力让ListPreference和HoloEverywhere一起工作。我在一个XML文件中定义了我的设置。我对属性使用了holo名称空间。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。
当我点击应用程序中的ListPreference时，问题就出现了。首选项应该会打开一个对话框，其中包含可供选择的选项。相反，它崩溃了，给出了下面的堆栈跟踪：

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" />我还想补充说，这发生在我的所有ListPreference项目(我有多个)。

好的。我已经弄明白了。
事实证明。HoloEverywhere 1.4.0中存在错误。已报告并修复了该问题：https://github.com/ChristopheVersieux/HoloEverywhere/issues/203
不幸的是，修复程序还没有合并到HE GitHub项目的主分支。它静静地坐在开发分支上，很可能是在等待下一个版本……
因此，如果你和我有同样的问题，那么你应该使用开发分支，或者派生存储库，然后选择THIS提交到你的主分支。
但是，样式没有正确应用于对话框的问题仍然存在。

} catch (ClassCastException e) {
Log.e("ArrayAdapter",

throw new IllegalStateException(

}
T item = getItem(position);
if (item instanceof CharSequence) {
text.setText((CharSequence) item);
} else {
text.setText(item.toString());
}
return view;
}textView似乎为空，并且未从布局中解析
