使用ViewPager显示Fragment集合

要注意包都要保持一致 ，在本文中是support.v4，不然会出现各种错误

activity_main.xml:

 1 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 2     xmlns:tools="http://schemas.android.com/tools"
 3     android:layout_width="match_parent"
 4     android:layout_height="match_parent"
 5     tools:context="com.zzw.fragmentteb.MainActivity" >
 6
 7     <android.support.v4.view.ViewPager
 8         android:id="@+id/view_pager"
 9         android:layout_width="match_parent"
10         android:layout_height="match_parent" />
11
12 </RelativeLayout>

MyFragment:
