该篇文章是一个ListFragment的一个实例，通过了解该实例，更能了解比较常用的ListFragment的用法，以及各Fragment之间的数据传递。
实现效果图：
该MainActivity中包括1个Button+2个Fragment（右边两个），点击Button，出现中间的list列表，点击列表中的任一项，相应item数值，会传递到右边的Fragment中并显示。
源代码：
activity_main:
<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="horizontal"
tools:context=".MainActivity" >
<LinearLayout
android:id="@+id/left"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="#CCCCCC"
android:orientation="vertical" >
<Button
android:id="@+id/button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="显示列表" />
</LinearLayout>
<LinearLayout
android:id="@+id/center"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="2"
android:background="#CCDDFF"
android:orientation="vertical" >
</LinearLayout>
<LinearLayout
android:id="@+id/right"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="2"
android:background="#CCFFDD"
android:orientation="vertical" >
</LinearLayout>
</LinearLayout>
ArticleListFragment本来也应该有一个布局文件，这里是在代码中方便的直接添加了个ListView，也是因为该类继承了ListFragment的缘故。
DetailFragment包含的布局文件：
<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="horizontal"
tools:context=".MainActivity" >
<TextView
android:id="@+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="30sp"/>
</LinearLayout>MainActivity：
