I need to make a little white line under my every recycler view item (from left to right corner), not for any particular element in that item, but for the whole item. (that way it's easier for a user to see which elements are in this particular item, and where another item starts)

Here is my item layout:

<?xml version="1.0" encoding="utf-8"?>
<androidx.cardview.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="@dimen/_5sdp"
    app:cardCornerRadius="0dp"
    app:cardElevation="0dp">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/colorPrimaryDark">

        <TextView
            android:id="@+id/nameView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Mike"
            android:textColor="@color/colorAccent"
            android:textSize="@dimen/_21sdp" …
