【问题讨论】：

在此处添加 XML 作为代码，而不是作为外部链接。
请至少再提供几句话，所以如果不是您，但其他人可以提供帮助并将 XML 附加到问题中。
您的具体要求是什么？请详细说明..!!
检查我下面的答案，将其粘贴到您的ConstraintLayout 并尝试。

解决方案：

只需将此代码粘贴到您的父级顶级ConstraintLayout 中并尝试：

<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
