Zoomlayout: Don't let specific imageview receive the zoom inside a ZoomLayout

I'm using the ZoomLayout, inside of it I have some imageviews that work as a menu, like that:

<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools">

    <com.otaliastudios.zoom.ZoomLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/skyZoomLayout"
        app:minZoom="1.0"
        app:maxZoom="5.0"
        app:hasClickableChildren="true">

            <FrameLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:id="@+id/sky">

                    <ImageView
                        android:id="@+id/button1 >

                    <ImageView
                        android:id="@+id/button1 >

            </FrameLayout>

    </com.otaliastudios.zoom.ZoomLayout>

</layout>

`
But I don't want these specific imageviews to receive the zoom, because they're a simple static menu on the bottom-left part of the screen. Is there a way to do it?
