I am doing a tutorial of the big nerd ranch and it does not seem to work for me at this point. I triple checked my code with theirs but it won't work. The XML is a new content_quiz.xml file which is located in layout-land, it does work partially since the next button is showing up at the right place.
The goal is this:
but my app looks like this: 
In vertical it does work though: 
The XML for the horizontal is the following:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="@+id/question_text_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:padding="24dp" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical|center_horizontal"
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>
<Button
android:id="@+id/next_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/next_button"
android:drawableRight="@drawable/arrow_right"
android:layout_gravity="bottom|right"
android:drawablePadding="4dp"/>
</FrameLayout>
The java activity file is as follows:

I tested this on android 6 and 6.0.1 on both my phone and the emulator. Both give the wrong styling and discard the TextView. What is going wrong here?
