CardView bottom border is cut off inside ScrollView android

UPDATED

This will work better now with a NestedScrollView and a MaterialCardView. I added this NestedScrollView to a ConstraintLayout.

<androidx.core.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginBottom="8dp"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent">

    <com.google.android.material.card.MaterialCardView
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      app:cardUseCompatPadding="true">

This is working for me without the LinearLayout wrapper.

OLD WAY LEFT HERE

I ran into the same problem and had to do the following (the key is the LinearLayout wrapper around the cardview where I added the paddingBottom):

<ScrollView
    android:id="@+id/item_scrollview"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scrollbars="none"
    tools:visibility="visible">

    <LinearLayout
        android:id="@+id/item_wrapper_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="@dimen/content_margin"
        android:paddingBottom="32dp"
        android:orientation="vertical">

        <android.support.v7.widget.CardView
            android:id="@+id/item_cardview"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            card_view:cardBackgroundColor="@color/colorPrimary"
            card_view:cardCornerRadius="4dp"
            card_view:cardUseCompatPadding="true">

Adding the LinearLayout wrapper around the cardview is what worked for me.

Also note, I had to add card_view:cardUseCompatPadding="true" on the cardview to get the border shadow looking correct.

Here is the end result where the red box shows where the padding has been added when the cardview is expanded and scrolled up.

Setting clipToPadding to false on a ScrollView usually works for me:

    <ScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:clipToPadding="false"
    android:paddingBottom="16dp">

    <com.google.android.material.card.MaterialCardView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="8dp"
        app:contentPadding="8dp">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            tools:text="Lorem ipsum..." />

    </com.google.android.material.card.MaterialCardView>

</ScrollView>

One solution I just found is to wrap CardView with a LinearLayout or RelativeLayout and set its padding. For example, If you want some drop shadow effect in cardView, lets say 8dp, you can set 4dp padding of your LinearLayout or RelativeLayout and 4dp layout_margin of CardView.
