如何在Android中创建两个视图,每个视图使用50%的高度,除非一个更小？

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <View
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:background="#FF0000" />

    <View
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#00FF00" />

</LinearLayout>

<androidx.constraintlayout.widget.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <View
        android:id="@+id/view1"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toTopOf="@id/view2"
        app:layout_constraintHeight_percent="0.5"
        android:background="#FF0000" />

    <View
        android:id="@+id/view2"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_constraintTop_toBottomOf="@id/view1"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintHeight_percent="0.5"
        android:background="#00FF00" />

</androidx.constraintlayout.widget.ConstraintLayout>
