Can there only be one

@Preview

function and does it need to be in the main activity?

You can have as many preview functions as you want in whatever files you want - when that file is open, it will show all those previews together at once.

Odd. If I paste my preview into the main activity it displays, but it doesn't if I define it in a new file

I think there's a bug where you need to reopen the file the first time you add a preview function

Yep, that did it. Thanks!

yep. that bug (i think?) is fixed on the latest canary build of studio, but i could be wrong

How far you see the preview if your function in an activity? Preview are meant to be top level functions 😧

i think perhaps he meant that it was in the same file. the IDE basically looks for the presence of @Preview when the file is opened, but doesn’t check after that
