ClassNotFoundException - android.support.v4.view.ViewPager

Question

我想創建一個帶有可滑動視圖的標籤佈局。在https://developer.android.com/tools/support-library/setup.html

現在這個XML文件的設計選項卡是給ClassNotFoundException

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" android:layout_height="match_parent"> 

<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/pager" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 
</android.support.v4.view.ViewPager> 

</LinearLayout> 

我已經加入支持庫通過以下步驟：要添加ViewPager我創建activity_fragments_logs.xml。這是個例外：

我已經閱讀了堆棧溢出的一個類似的問題，但它涉及Eclipse和我正在使用Android Studio。

Updated SDK version, getting ClassNotFoundException: android.support.v4.view.ViewPager

我已經搜索了很多關於這一點，但我無法找到任何有用的東西。

從視圖中刪除尋呼機這應該是上層次
