Android约束布局-将视图固定到页面底部和另一个视图的下方(而不是介于两者之间)

<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">

    <View
        android:id="@+id/view1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#FF0000"
        app:layout_constraintBottom_toBottomOf="parent" />

    <View
        android:id="@+id/view2"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#00FF00"
        app:layout_constraintTop_toBottomOf="@id/view1" />

</androidx.constraintlayout.widget.ConstraintLayout>
