ConstraintLayout 佈局中有ScrollView 時，ScrollView 的寬高要設定為0dp 才可以正確的約束佈局

 <ScrollView
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:fillViewport="true"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf
 
="parent"
        app:layout_constraintTop_toBottomOf="@+id/layout_item_binding_card_indicator">
 </ScrollView>
