How to zoom in Android Layout Editor?

This is how Layout Editor looks like when I click on Preview all Screen sizes

XML Layout Editor

Clicking on + and - does nothing. Without zooming I can't see Preview on all Screen sizes clearly. How can I zoom in and out to see everything clearly?

Is this a issue with Android Studio or I am doing it wrong way?

In Preferences > Editor, there's an option "Change font size (Zoom) with Command+Mouse Wheel". (I'm on MacOS; on other platforms it might be control+mouse wheel). You can also go into Preferences > Keymap > Editor Actions > Decrease Font Size/Increase Font Size/Reset Font Size and bind some keys to those commands.

I was having the same problem, but what solved for me was changing the theme of Android Studio. When I couldn't zoom in or out in the XML Editor I just changed from Darcula theme to IntelliJ theme and it worked just fine.

I hope it works for you too or someone have the same issue!
