How to display Name in your Layout dynamically?

I am working on an Android App, which needs to have a friend list. I am communicating to Server, Server returns me a "Name", how do I display this Name in my Layout.

My xml code:

 <LinearLayout 
    android:gravity="top" 
    android:layout_width="match_parent"
    android:layout_height="0dip"
    android:layout_weight="1"
    android:orientation="horizontal" > 
 <TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="My Friend List" />
 </LinearLayout>

 <View
    android:layout_width="fill_parent"
    android:layout_height="1dp"
    android:background="@android:color/darker_gray"/>

 <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="0dip"
    android:layout_weight="1"
    android:gravity="top"
    android:orientation="horizontal" >

 <ImageButton
     android:id="@+id/imageButton1"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:src="@drawable/add_more_friends" />

</LinearLayout>

</LinearLayout>
