Without custom view, you can have this shape with below XML:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 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"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">


    <androidx.appcompat.widget.LinearLayoutCompat

        android:layout_margin="24dp"
        android:elevation="4dp"

        android:weightSum="2">

        <androidx.appcompat.widget.LinearLayoutCompat

            android:weightSum="5">

            <FrameLayout
                android:layout_width="0dp"
                android:layout_height="match_parent"
                android:background="#FFFFFF"
                android:layout_weight="2" />

            <View
                android:layout_width="4dp"
                android:layout_height="match_parent"
                android:visibility="visible"/>

            <View
                android:layout_width="0dp"
                android:layout_height="match_parent"
                android:layout_marginEnd="6dp"
                android:layout_weight="3"

        </androidx.appcompat.widget.LinearLayoutCompat>

</FrameLayout>

there is a Material Card View and an empty view on top of that to cover an unneeded corner of that.
