将TextView和ScrollView放在其他两个视图（页眉和页脚）之间

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

我已经尝试过并查找了多个页面，但是我的问题始终是，尽管进入“ ScrollMode”，但表示“某些文本”的文本“ text” TextView总是超出了其他两个视图之间的空间

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android:scrollbars = "vertical"您的此属性TextView还会松散不合适的textview周围的约束属性。在这里，我做了一些更改，使textview可滚动：

<?xml version="1.0" encoding="utf-8"?>

    android:layout_height="match_parent">

        android:layout_marginEnd="8dp"

        app:layout_constraintEnd_toEndOf="parent"
