ViewPager動態加載佈局

第一個xml代碼：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.viewpager2.MainActivity$PlaceholderFragment" >

    <android.support.v4.view.ViewPager
        android:id="@+id/viewPager"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center" >

        <android.support.v4.view.PagerTitleStrip

        </android.support.v4.view.PagerTitleStrip>
        
    </android.support.v4.view.ViewPager>

</LinearLayout>

第二個xml代碼：
