Do you mean you accept 
context
as a parameter in your function?

@Preview
doesn't accept parameters, so it must be used with default values; i need context object to load resources as default values

To;Dr; you can create a wrapper function which provides everything to your '@composable' function and annotate that function with '@preview'

I already do it, but 
@Preview
works only outside Activity (or Fragment) , and outside Activity i haven't context object

Wrong, you have access to context inside 
@Composable
functions
Just retrieve it 
val context = +ambient(ContextAmbient)
