    Use this code instead:

     <ImageButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/imageButton" android:layout_gravity="center_horizontal" android:src="@drawable/admin"
        android:cropToPadding="false" android:background="null"/>

    You didn’t assign an image to your ImageView… You need a line in your XML that says 

    android:src="@drawable/some_image"

    The background and source are different
