setOnClickListener not fired on Layout

Question

I'm trying to put a click listener on a ConstraintLayout but it's never fired. I don't know why I tried to look about android:clickable but I didn't get any better

This is what I have in my parent view:

<include
    android:id="@+id/search_scanner"
    layout="@layout/scan_button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"/>

The layout scan_button is the following:

<androidx.constraintlayout.widget.ConstraintLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:id="@+id/scan_layout"
        xmlns:app="http://schemas.android.com/apk/res-auto">

    <LinearLayout
            android:id="@+id/scan_button"
            app:layout_constraintTop_toTopOf="parent"
            app:layout_constraintLeft_toLeftOf="parent"
            app:layout_constraintRight_toRightOf="parent"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@drawable/button_registration_social_networks"
            android:backgroundTint="@color/orange"
            android:paddingHorizontal="15dp"
            android:paddingVertical="5dp"
            android:layout_marginRight="10dp">

        <ImageView
                android:id="@+id/scan_button_image"
                android:layout_width="32dp"
                android:layout_height="32dp"
                android:paddingLeft="5dp"
                android:src="@drawable/icon_scan"
                android:layout_gravity="center"/>

        <TextView
                android:text="@string/scan_book"
                android:textColor="@color/colorAccent"
                android:textStyle="bold"
                android:textSize="18sp"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center"
                android:paddingLeft="10dp"/>

    </LinearLayout>

    <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/scan_book_text"
            android:textColor="@color/grey"
            android:layout_marginTop="10dp"
            android:lines="2"
            app:layout_constraintLeft_toLeftOf="parent"
            app:layout_constraintRight_toRightOf="parent"
            app:layout_constraintTop_toBottomOf="@+id/scan_button"/>

</androidx.constraintlayout.widget.ConstraintLayout>

And this is what I'm doing about the listener:

search_scanner.setOnClickListener {
    startActivity(Intent(context, ScannerActivity::class.java))
}

If you have some answers about it, I'll be glad!

EDIT : I solved it ! I just add an elevation on my layout because the scan layout was at the same level with a ListView (either the listview was empty). So it's working !

Thanks guys for your help
