Fire not show functions parameters?

I’m trying to build a basic App hopping to see how build a simple login screen by code (https://sourcey.com/beautiful-android-login-and-signup-screens-with-material-design/) but after problems importing libraries I blame that for the fact I don’t see function params (or type information on properties) at autcompleting a method/function.

But then I recheck and see a working project and… it not show… This is odd. And make very time consuming to develop programs.

ie, I mean that if I writefindViewById( I expect to see what I need to fill and how many params and types.

Command-P will show you the list of parameters for the current method call.
