两个滚动视图，这可能吗？

编程问答 2022-08-15

问题描述

我的代码可以得到一些帮助吗？我需要红色区域才能垂直滚动。我需要黑色区域才能垂直和水平滚动。我还附加了一些.java代码和.xml代码。我尝试了不同的方法，但总体而言无法重现效果。我了解到，如果不更改子项或其他内容，您将无法同时拥有两个滚动视图。不过我不太明白那句话。

对社区表示感谢！

.xml代码

<ScrollView
    android:id="@+id/layout"
    android:layout_width="324dp"
    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"
        android:scrollbars="horizontal|vertical">

        <TableLayout
            android:id="@+id/tableLayoutProduct"
            android:layout_width="match_parent"
            android:layout_height="match_parent"></TableLayout>
    </horizontalscrollview>
</ScrollView>`

解决方法

好，来自大量研究。我了解到这在android中尚不可能。如果我错了，请纠正我，但是我发现ScrollView无法滚动垂直和水平滚动。
