I have CustomView rather than Relative Layout under Device Screen

Hi. I currently have Hello World coming out on the screen, but when I am on activity_funfacts.xml, my DeviceScreen has Custom View. My code looks like this:

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout 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:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" app:layout_behavior="@string/appbar_scrolling_view_behavior" tools:context="practice.funfacts.FunFactsActivity" tools:showIn="@layout/activity_fun_facts">

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Hello World!" />

</RelativeLayout>

Do you have a layout called content_funfacts?

Yes. The code in contents and activity seem to be flipped

In Android Studio 1.5.1 I had to start over and choose an "Empty Activity" when creating the project instead of the "Blank Activity" which seems to have changed in layout and functionality since Ben made the course.

Thank you. But then there is no contents_funfacts.xml. Is that okay for the rest of the tutorial?

Hey! The contents_funfacts.xml is just used to separate the content(file name says that) from the rest of the layout. You can either use that content_funfacts.xml file and put all the code Ben puts in the other xml file in your content file.

If you don't have that content xml file that's no problem. You can still use the regular xml file. Have a look at the activity xml file and you'll see an include statement that includes the content xml file. So it is just outsourcing the contents of your layout to a different file.

Hope I was able to help!
