Android滑動標籤，Fragment_Collection_Object錯誤

Question

在Android開發者網站上爲我的項目添加滑動選項卡到我的Android應用程序，我被這個錯誤卡住了，並且不理解問題，我知道它與調用有關正確的片段佈局，我正在做的正是教程告訴我的，有沒有人有任何信息來解決這個問題，謝謝。

的錯誤是在線126

的錯誤是：描述資源路徑位置類型 fragment_collection_object不能得到解決或無法在現場MainActivity.java /登錄/ src目錄/ com/test/finalproject line 126 Java問題

Answer 1

您遇到的問題是由於項目/ res

的佈局文件夾中缺少xml文件

轉至http://developer.android.com/training/implementing-navigation/lateral.html
單擊「下載示例應用程序」並將其解壓縮。將EffectiveNavigation \ res \ layout \ fragment_collection_object.xml添加到項目\ res \ layout中。這個，我想會解決問題。
