    }

這是我Detailactivity我爬MenuitemCompat它說，它無法解析符號錯誤「MenuitemCompat」MenuItemCompat無法解決

這是我detailfragment.xml

<?xml version="1.0" encoding="utf-8"?> 
<menu xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:bwq="http://schemas.android.com/apk/res-auto"> 

    <item 
     android:id="@+id/action_share" 
     android:title="@string/action_share" 
     android:showAsAction="always" 
     /> 

</menu>

誰能幫我並向我解釋我在做什麼錯是錯的

解決：我對這篇文章使用了第二個答案 Want to use ViewPager, cannot get android.support.* to be recognized?

新增V4，V7和V13 libary的，並與我的一切都進口一些小的調整工作

如果你還沒有加入此導入到你的Detailactivity你可能會得到這個錯誤。

import android.support.v4.view.MenuItemCompat;

以及進口android.support.v4.view。我得到一個未使用的導入和MenuItemCompat我仍然得不到解決符號 –

它適用於我。確保將其添加到您創建「ShareActionProvider」的活動中。 – krrish

我更新帖子我張貼洞活動，現在你可以看到我使用進口jet我得到的錯誤我告訴你的導入和MenuItemCompat –

解決：我在本文中使用了第二個答案想要使用ViewPager，無法獲取android.support。*進行識別嗎？
