You want to implement

V

, an type not known at compile time?

Yes, it would make my Mvp implementation a bit simpler

But you logically can't do that, what if whatever

V

ends up doing adds some more functions to implement?

BaseActivity

is anyways abstract. Shouldn’t that be the responsibility of the concrete class.

what about

inline <reified V: BaseView> MyActivity() {
    return object : BaseActivity<V, P> {
          //What methods does `V` have?
     }

That's the first problem. The second one is that you can't tell the compiler that

V

must be either an interface or an open class, because if you use a final class as

V

, the whole thing doesn't work too (can't inherit from a final class)
