CardView bottom border is cut off inside ScrollView android

Question

I am putting the cardview inside scrollview, we expect to see that at the bottom, the border should be shown（see pic below）. But its not. The problem is that I cannot scroll to the bottom to see the border of cardview.

All the solutions on SO is to change layout_margins to paddings, but its not the case for cardview if we want to show the border. I basically tried everything. But still doesnt work.

Picture 1. scroll to bottom cannot see the border

Picture 2. We can see the top border

Following is xml code

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:custom="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fillViewport="true">

            <android.support.v7.widget.CardView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_margin="8dp">
                    <LinearLayout
                      android:layout_width="match_parent"
                      android:layout_height="wrap_content"
                      android:orientation="vertical"
                      >
                     ...
                    </LinearLayout>
           </CardView>
  </LinearLayout>

references: ScrollView doesn't scroll to the bottom

ScrollView cuts off the top and leaves space at the bottom

I can't show LinearLayout at bottom to scroll view

Android ScrollView refuses to scroll to bottom

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.
