using Kotlin 1.20.20 (not that it matters, older versions behaves the same)

When layout is in separate library module Android Studio has no problem finding and refer

Answer 1

Preconditions

Do not import the following library import kotlinx.android.synthetic.main.my_view.view.*

app/MainActivity.kt

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        val view: View = MyView(this)
        view.findViewById(R.id.textViewPocLib).text = "I can edit the library components"
        setContentView(view)
}

my_library/MyView.kt

class MyView @JvmOverloads constructor(context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0) :
    LinearLayout(context, attrs, defStyleAttr) {

    init {
        LayoutInflater.from(context)
            .inflate(R.layout.my_view, this, true)
    }
}
