Image getting behind the background

Question

I would like to put an image in front of another image. I’ll explain it better. I have a background and want to put an image on the dividing line between Relativelayout and Scrollview.

On native android I have the option:

app:layout_anchorGravity="bottom|end"

That stays that way:

Suppose instead of that icon you put an image.

But look at mine:

Follows the code:

<?xml version="1.0" encoding="utf-8"?
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:diagonal="http://schemas.android.com/tools"
    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"
    android:layout_height="match_parent">

        android:fitsSystemWindows="true"
        app:diagonal_angle="20"
        diagonal:diagonal_direction="left"
        diagonal:diagonal_position="bottom">

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:scaleType="centerCrop" />
