You have to select an device to get the preview according to it. – Aditya Jul 24 '18 at 05:13

no problem with zoom level dude, – Muhammad Hassaan Jul 24 '18 at 05:13

do one thing, on left side of **AppTheme** near to zoom level , there you see an option showing **null**, change it's API Level example to 27 or some other. That will help you – Vishal Thareja Jul 24 '18 at 05:22

Try the following steps, in order if one does not work try the next one
- Switch to text editor (button at bottom), Check if there are any errors in the layout.
- In the text editor too there is a preview part so you can check if that is working
- Build clean (Preview is not shown if build is not successful)
- Invalidate cache and restart
- Update Android studio
