android - 如何在两个 View 之间对齐底部并同时将顶部对齐到父级？

Question

我试图在两个 View 之间对齐底部并将它们对齐到父 View 的顶部。当他们中的任何一个比另一个高时，它就会失败。好像app:layout_constraintBottom_toBottomOf="@id/rightText"和 app:layout_constraintTop_toTopOf="parent"相互矛盾。

<?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">

    <TextView
        android:id="@+id/leftText"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginEnd="32dp"
        app:layout_constraintBottom_toBottomOf="@id/rightText"
        app:layout_constraintEnd_toStartOf="@id/rightText"
        app:layout_constraintHorizontal_weight="3"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        tools:text="Header Header Header Header Header Header Header Header" />

    <TextView
        android:id="@+id/rightText"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        app:layout_constraintBottom_toBottomOf="@id/leftText"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_weight="1"
        app:layout_constraintStart_toEndOf="@+id/leftText"
        app:layout_constraintTop_toTopOf="parent"
        tools:text="RightHeader RightHeader RightHeader RightHeader" />

</androidx.constraintlayout.widget.ConstraintLayout>

将两个 View 的顶部连接到 parent 并将两个 View 中的每一个的底部相互连接，然后使两个文本中的垂直偏差等于 1
