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。

我自己已经尝试过并查找了多个页面，但是我的问题始终是显示“某些文本”的文本“文本”TextView 总是超出其他两个视图之间的空间，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 的这个android:scrollbars = "vertical" 属性也会放松不合适的textview 周围的约束属性。这里我做了一些改变，这使得 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"

    <ScrollView

            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>
