I want the grey shade as shown in previews but mine has white as default. I tried to search in file->settings but without much success. Also, I couldn't find Project->clean or any such option. Any help will be appreciated, thanks!

- 4If you want only change background on whatever theme you are Preferences > Editor > Color & Fonts > General > Default Text > Background. You could not do this on default theme hence you need to create a copy of default theme as android studio will guide you if you click on background selection rectangle.Eftekhari– Eftekhari2015-07-12 11:50:10 +00:00Commented Jul 12, 2015 at 11:50

You can change it by going File => Settings (Shortcut CTRL+ ALT+ S) , from Left panel Choose Appearance , Now from Right Panel choose theme.

Android Studio 2.1
Preference -> Search for Appearance -> UI options , Click on DropDown Theme
Android 2.2
Android studio -> File -> Settings -> Appearance & Behavior -> Look for UI Options
EDIT :
Import External Themes
You can download custom theme from this website. Choose your theme, download it. To set theme Go to Android studio -> File -> Import Settings -> Choose the
.jarfile downloaded.

How do I change Android Studio editor's background color?
Changing Editor's Background
Open Preference > Editor (In IDE Settings Section) > Colors & Fonts > Darcula or Any item available there IDE will display a dialog like this, Press 'No'
Darcula color scheme has been set for editors. Would you like to set Darcula as default Look and Feel?
Changing IDE's Theme
Open Preference > Appearance (In IDE Settings Section) > Theme > Darcula or Any item available there Press OK. Android Studio will ask you to restart the IDE.
