ViewPager动态加载布局

第一个xml代码：

<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:id="@+id/pagerTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="top" >
</android.support.v4.view.PagerTitleStrip>

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

</LinearLayout>

第二个xml代码：
<?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:orientation="vertical" >

<RatingBar
android:id="@+id/ratingBar1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />

<ProgressBar
android:id="@+id/progressBar1"
style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp" />

<QuickContactBadge
android:id="@+id/quickContactBadge1"
android:layout_width="wrap_content"
