Android Holoeverywhere DatePreference错误

标签： android android-preferences android-holo-everywhere

我正在使用Holoeverywhere图书馆。我应该优先选择用户选择日期。我把这个偏好放在我的文件中，就像这样

<org.holoeverywhere.preference.DatePreference
        android:key="preference_birth_date"
        android:summary="@string/preference_birth_date"
        android:title="@string/preference_birth_date" />

当我启动首选项屏幕时，我收到以下错误：

当我从XML文件中删除首选项时，一切正常。我只在XML中设置了我在代码中没有做任何事情的偏好。

答案 0 :(得分：1)

您的商店中有一个键preference_birth_date的字符串值。它是由先前使用EditTextPreference使用相同密钥引起的。只需清除应用数据或将密钥更改为其他内容即可。

答案 1 :(得分：0)

看起来你尚未实现的类'ComponentInfo'在将字符串转换为long时遇到问题，查看该类的代码或覆盖'ComponentInfo'的任何子类中的'onCreate'方法。
