गतिशील रूप से एक टुकड़ा जोड़ना

activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"  
    android:layout_width="fill_parent"  
    android:layout_height="fill_parent" >  
  
    <FrameLayout  
        android:id="@+id/container1"   
        android:layout_width="0px"  
        android:layout_height="match_parent"   
        android:layout_weight="1"  
        />  
  
    <FrameLayout  
        android:id="@+id/container2"   
        android:layout_width="0px"  
        android:layout_height="match_parent"  
        android:layout_weight="1"  
         />  
  
</LinearLayout>

FrameLayout टुकड़ा कंटेनर के रूप में कार्य कर रहा है।
