Android Holoeverywhere DatePreference错误

我正在使用Holoeverywhere库。我应该有一个偏好，用户选择一个日期。我把这种偏好在我的文件中像这样Android Holoeverywhere DatePreference错误

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

当我开始偏好屏幕出现以下错误：

当我删除从XML中的首选项文件，一切工作正常。我只在XML中设置了偏好，我没有在代码中做任何事情。

您的商店中有密钥preference_birth_date的字符串值。它由早前使用相同密钥使用EditTextPreference引起。只需清除应用数据或将密钥更改为其他内容即可。

噢，好的...那有效。非常感谢你......你救了我的生命:) – Tooroop

btw ...当我设置一个onDateSetListener时，在onDateSet（）方法中，当我得到月份值时，该值总是比它应该小1。当我设置1月份的月份值为0，并且当我设置12月份时，月份值为11 ...这是预期的行为吗？ – Tooroop

看起来您还没有实现类的ComponentInfo'与铸造串地龙的问题，考虑该类或重写代码“的onCreate的方法在“ComponentInfo”的任何子类。

我认为ComponentInfo和这个没有任何关系:) – Tooroop
