Support LayoutId constructors for AppCompatActivity and (AndroidX)Fragment

[kikuchy]

Latest AndroidX AppCompat library supports LayoutId constructor.

https://developer.android.com/jetpack/androidx/releases/appcompat#1.1.0

I want to RxLifecycle's RxAppCompatActivity ,etc... supports that constructor.

I'm a fan of doing this, but this PR only supports a subset of the components for the new constructor. Any particular reason?

Isn't it enough reason?
I want to use LayoutId constructor on AppCompatActivity.

If you think it's not enough reason, it ok to close this Pull Request.

I'm asking why the PR is incomplete. It's only using LayoutId for some components, but not for others. We should support them all.

Thank you. Now I'm understanding your opinion.

incomplete

What incomplete?
Only AppCompatActivity/FragmentActivity/(androidx.fragment.app.)Fragment has LayoutId constructor (To be exact, ComponentActivity has LayoutId constructor but RxLifecycle has no direct child class of it), so only RxAppCompatActivity/RxFragmentActivity/(support.)RxFragment have been changed.

Oh weird, I assumed it'd be for all components, not just a handful of them.
