ANDROID - Using Fragments

I have used android-support-v4.jar because i have to run this in my Android 2.2.1 Device





Main Activity:

 package com.example.freagmenttest;  
 import android.os.Bundle;  
 import android.support.v4.app.FragmentActivity;  
 import android.view.Menu;  
 public class MainActivity extends FragmentActivity {  
      @Override  
      public void onCreate(Bundle savedInstanceState) {  
           super.onCreate(savedInstanceState);  
           setContentView(R.layout.activity_main);  
      }  
      @Override  
      public boolean onCreateOptionsMenu(Menu menu) {  
           getMenuInflater().inflate(R.menu.activity_main, menu);  
           return true;  
      }  
 }

activity_main.xml

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"  
   android:orientation="horizontal"  
   android:layout_width="fill_parent"  
   android:layout_height="fill_parent">  
   <fragment android:name="com.example.freagmenttest.ItemClass"  
        android:id="@+id/headlines_fragment"  
        android:layout_weight="1"  
        android:layout_width="0dp"  
        android:layout_height="match_parent" />  
   <fragment android:name="com.example.freagmenttest.DetailsClass"  
        android:id="@+id/article_fragment"  
        android:layout_weight="2"
