在 1080p 分辨率的手机中看起来像这样：

我的问题是：图像中的蓝色框（HistoryLinearLayout）是较小的屏幕看起来太小了，我希望最小高度为 150sp（我尝试在 HistoryLinearLayout 中添加 minHeight，但它没有做任何事情）和图像中的黄色部分发生这种情况时可以滚动，因此如果黄色部分不适合并且同时 HistoryLinearLayout 至少为 150sp，则黄色部分将出现滚动条。

现在它不起作用，滚动条没有做任何事情，并且 minHeight 没有得到尊重。

换句话说，我想要的是：如果蓝色部分 (HistoryLinearLayout) 小于 150sp，则将其设为 150sp 并使黄色部分 (ScrollView) 可滚动。我不介意这是否也可以通过代码发生。

【问题讨论】：

代码未完成，无法重现。根据我的测试，当里面的元素超出高度时，滚动视图会滚动。您能否提供代码来重现您的问题？
@Wendy 谢谢，所以在你的测试中历史布局总是可见的，如果没有足够的空间滚动视图正在拉伸内容？在我的测试中奇怪的是，滚动视图就像它不存在一样，历史布局可能看起来非常小。我稍后会提供代码
等待您的代码。
@WendyZang-MSFT 我已经用所有布局文件更新了代码

【解决方案1】：

约束让你构建灵活的布局。

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >

    <ScrollView
        android:id="@+id/scroll"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:background="#aa3"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toTopOf="@id/blue"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        >

        <TextView
            android:layout_width="30dp"
            android:layout_height="wrap_content"
            android:text="aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
            android:textSize="24dp"
            />
    </ScrollView>

    <FrameLayout
        android:id="@+id/blue"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:background="#33f"
        android:minHeight="150dp"
        app:layout_constraintTop_toBottomOf="@id/scroll"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        >

        <TextView
            android:layout_width="30dp"
            android:layout_height="wrap_content"
            android:text="bbb"
            android:textSize="24dp"
            />
    </FrameLayout>
</androidx.constraintlayout.widget.ConstraintLayout>

如果您将滚动和蓝色都设置为layout_height="0dp"，它们总是共享均匀空间。

【讨论】：

我一直觉得设置 layout_height="0dp" 在某种程度上是一种 hack，而 tere 应该是另一种更好的解决方法，但我认为我们仍然需要它，谢谢
它在我的情况下不起作用，因为如果我使用您的代码并将 android:layout_height="wrap_content" 设置为蓝色，我在历史布局中有一个隐藏的列表视图，我们是否有任何解决方法这？我还在问题中包含了 historylinearlayout，并根据您的建议更新了主布局文件
0dp 不是 ConstraintLayout 中的 hack。这意味着“高度是从约束中定义的”。如果是 wrap_content，则表示“高度至少是 wrap 但要考虑约束”。如果您对蓝色的静态高度没问题，请尝试蓝色的“0dp”。它使两个区域均匀。
