Updated xml:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:pj="http://schemas.android.com/apk/res/com.globems.main"
    xmlns:bm="com.carousel.main"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background ="@drawable/blue3"

        android:gravity="top"

                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:id="@+id/carousel"  
                pj:UseReflection="true"
                pj:Items="@array/entries"
                pj:Names="@array/names" 
                pj:SelectedItem="0"

            />    
        <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher"
        android:centerinHorizontal="true"
        />

    </RelativeLayout>

Answer 1

its better to Use RelativeLayout and add android:centerinParent="true" in imageView...

UPDATE ::

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:pj="http://schemas.android.com/apk/res/com.globems.main"
    xmlns:bm="com.carousel.main"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/blue3" >

    <com.globems.controls.Carousel
        android:id="@+id/carousel"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        pj:Items="@array/entries"
        pj:Names="@array/names"
        pj:SelectedItem="0"
        pj:UseReflection="true"
        android:animationDuration="200" />

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:src="@drawable/icon" />

</RelativeLayout>
