android resource linking failed

[hq-99]

很多xml里显示 can't resolve symbol 是包的问题吗
报错信息如下：

res\layout\activity_calender.xml:9: AAPT: error: attribute mcv_showOtherDates (aka com.example.wink:mcv_showOtherDates) not found.
menu\main_menu.xml:5: AAPT: error: resource drawable/ic_action_action_search (aka com.example.wink:drawable/ic_action_action_search) not found.
