在其他两个视图（页眉和页脚）之间放置一个带有 ScrollView 的 TextView

Question

我想在 ScrollView 中有一个可滚动的 TextView / TextView。

我已经自己尝试过并查找了多个页面，但是我的问题始终是文本“文本”TextView 表示“某些文本”总是超过其他两个视图之间的 space 尽管进入“滚动模式”

这是我的 XML 代码：

<?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"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
<ImageView
    android:id="@+id/imageView"
    android:layout_width="150dp"
    android:layout_height="150dp"
    android:layout_marginStart="8dp"
    android:layout_marginLeft="8dp"
    android:layout_marginTop="40dp"
    android:layout_marginEnd="8dp"
    android:layout_marginRight="8dp"
    android:layout_marginBottom="8dp"
    app:layout_constraintBottom_toTopOf="@+id/title"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent" />

<TextView
    android:id="@+id/title"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_marginStart="32dp"
    android:layout_marginLeft="32dp"
    android:layout_marginTop="45dp"
    android:layout_marginEnd="32dp"
    android:layout_marginRight="32dp"
    android:gravity="center_horizontal"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toBottomOf="@+id/imageView"
    tools:targetApi="jelly_bean" />

<ScrollView
    android:id="@+id/scrollView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginStart="32dp"
    android:layout_marginLeft="32dp"
    android:layout_marginTop="32dp"
    android:layout_marginEnd="32dp"
    android:layout_marginRight="32dp"
    android:layout_marginBottom="32dp"
    android:orientation="vertical"
    app:layout_constraintBottom_toTopOf="@+id/linearLayout"
    app:layout_constraintEnd_toEndOf="@+id/title"
    app:layout_constraintStart_toStartOf="@+id/title"
    app:layout_constraintTop_toBottomOf="@+id/title">

    <TextView
        android:id="@+id/middleText"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:text="some text"
        tools:targetApi="jelly_bean" />
</ScrollView>

<LinearLayout
    android:id="@+id/linearLayout">

... 

    </LinearLayout>
</androidx.constraintlayout.widget.ConstraintLayout>

设置 TextView 的 android:scrollbars = "vertical" 属性也会放松对文本视图的限制属性，这是不合适的。在这里我做了一些改变，使 textview 可以滚动：

<?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"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <ImageView
        android:id="@+id/imageView"
        android:layout_width="150dp"
        android:layout_height="150dp"
        android:layout_marginStart="8dp"
        android:layout_marginLeft="8dp"
        android:layout_marginTop="40dp"
        android:layout_marginEnd="8dp"
        android:layout_marginRight="8dp"
        android:layout_marginBottom="8dp"
        app:layout_constraintBottom_toTopOf="@+id/title"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <TextView
        android:id="@+id/title"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginStart="32dp"
        android:layout_marginLeft="32dp"
        android:layout_marginTop="45dp"
        android:layout_marginEnd="32dp"
        android:layout_marginRight="32dp"
        android:gravity="center_horizontal"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/imageView"
        tools:targetApi="jelly_bean" />

    <ScrollView
        android:id="@+id/scrollView"
        android:layout_width="344dp"
        android:layout_height="50dp"
        android:layout_marginTop="32dp"
        android:orientation="vertical"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/title">

        <TextView
            android:id="@+id/middleText"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:scrollbars="vertical"
            android:text="some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text some text"
            tools:targetApi="jelly_bean" />
    </ScrollView>

    <LinearLayout
        android:id="@+id/linearLayout"
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:layout_marginTop="32dp"
        android:orientation="horizontal"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/scrollView"
