【问题描述】：
我可以就我的代码获得一些帮助吗？我需要红色区域垂直滚动。我需要黑色区域垂直和水平滚动。我还附上了一些 .java 代码和 .xml 代码。我尝试了不同的东西，但总体上无法重现效果。我读到你不能同时拥有两个滚动视图，而不改变孩子或其他东西。不过我不太明白这个说法。
感谢社区！
.xml 代码
<ScrollView

android:layout_height="822dp"
android:layout_marginEnd="4dp"
android:layout_marginRight="4dp"
android:layout_marginBottom="8dp"
android:fillViewport="true"
android:scrollbarStyle="outsideInset"
android:scrollbars="horizontal|vertical"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.0">
<HorizontalScrollView
android:id="@+id/horizontalView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dip"
