Try this:

Use : RelativeLayout, use: android:layout_centerInParent="true".

or

android:layout_gravity="center" to your ImageView

or

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:orientation="vertical" 
            android:layout_width="fill_parent"
            android:layout_height="fill_parent">
<Button
    android:id="@+id/btnCancel"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:background="@drawable/btn_login_selector"
    android:padding="10dp"
    android:text="@string/title_cancel"
    android:textAppearance="?android:attr/textAppearanceMedium"
    android:textColor="@android:color/white" />

     <LinearLayout 
            android:orientation="vertical" 
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:gravity="center">
 <ImageView
        android:id="@+id/ivProductImageDisplay"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:scaleType="matrix"
        android:padding="10dp"
        android:layout_above="@+id/btnCancel"
        android:scaleType="centerInside"
        android:src="@drawable/ic_app_bg_logo" />
</LinearLayout>
</LinearLayout>
