Why can't I see text in activity_main.xml when I create a new Android Studio project?

Question

Hi I'm new to Android Studio 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 ConstraintLayout.

Has anyone else experienced this? I've tried reinstalling the program and have also watched a few videos without much luck.

This is a common problem in Android Studio.

Just go to styles.xml file and change:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

to

<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">

The keyword here is to add Base
