I am using Android Studio 3.1.4, and the following is what is happening when I preview the layout:
- question_text: displays the question normally (Canberra is the capital of Australia.)
- true_button: displays normally (True)
- false_button: displays normally (False)
- app_name: does not display in preview (however, it displays fine in the emulator)
Is this the correct behavior that should be expected? See the image below:
