解：

只需将此代码粘贴到您的父顶级ConstraintLayout然后尝试：

<android.support.constraint.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="0dp"
    app:layout_constraintBottom_toTopOf="@+id/navigation"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent">

    <android.support.v4.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:isScrollContainer="true">

        <android.support.v7.widget.CardView
            android:id="@+id/cardView"

            android:layout_height="143dp"
            android:layout_marginStart="8dp"
            android:layout_marginLeft="8dp"
            android:layout_marginTop="16dp"
            android:layout_marginEnd="8dp"
            android:layout_marginRight="8dp"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent">

            <ImageButton

                android:scaleType="centerCrop"
                app:srcCompat="@mipmap/ic_launcher" />

        </android.support.v7.widget.CardView>
