title: How can I change between night mode and light mode on Android Studio preview?
body: <p>I'm starting to implement dark mode on my app and I'm using <code>Theme.AppCompat.DayNight.NoActionBar</code>. Everything is working fine on the device but I want to see the differences on the Android Studio so I don't have to keep running the code in order to see the changes.</p>
  
  <p>How can I switch the Android Studio Preview to show me the night mode vs light mode themes?</p>
  
  <p>Thanks.</p>
  
  <p>Edit: just to be clear, I want to show on Preview whatever I have on resource folders <code>-night</code> instead of the normal resource folder. </p>
