Ch3 - For the more curious: Landscape Layout

Android Programming (5th Edition) 3. The Activity Lifecycle
1

For this challenge in order to get the Next button at the bottom right, I had to wrap it inside another Linear Layout:

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="end">
        <Button
            android:id="@+id/next_button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/next_button"
            android:layout_gravity="bottom"
            app:icon="@drawable/arrow_right"
            app:iconGravity="end" />

However, with the previous chapter challenge in mind, in order to get the Previous button to similarly be in-line and on the left-hand-side, this seemed more complicated and I had to use a “Space” view to get the desired effect:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
    android:gravity="center"
    android:orientation="vertical"
    tools:context=".MainActivity">

    <TextView
        android:id="@+id/question_text_view"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="24dp"
        android:gravity="center"
        tools:text="@string/question_australia" />
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal">
        <Button
            android:id="@+id/true_button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/true_button" />

        <Button
            android:id="@+id/false_button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/false_button" />
    </LinearLayout>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="bottom"
        android:orientation="horizontal">
        <Button
        android:id="@+id/prev_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/prev_button"
        app:icon="@drawable/arrow_left"
        app:iconGravity="start" />

        <Space
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"/>

        <Button
            android:id="@+id/next_button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/next_button"
            app:icon="@drawable/arrow_right"
            app:iconGravity="end" />
    </LinearLayout>
</LinearLayout>

Is there a “better” way of doing this challenge?
