title: Why can't I see text in activity_main.xml when I create a new Android Studio project?
body: <p>Hi I'm new to <code>Android Studio</code> and am running into some trouble with starting a new project. I want to design an app, but unfortunately I cannot see any of the components I place in the <code>ConstraintLayout</code>.</p>
  
  <p>Has anyone else experienced this? I've tried reinstalling the program and have also watched a few videos without much luck.</p>
