Answer 1

If you want to use a Compose in your XML file, you can add this to your layout file:

<androidx.compose.ui.platform.ComposeView
    android:id="@+id/my_composable"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

and then, set the content:

findViewById<ComposeView>(R.id.my_composable).setContent {
    MaterialTheme {
        Surface {
            Text(text = "Hello!")
        }
    }
}

if you want the opposite, use an XML file in your compose, you can use this:

    AndroidView(
        viewBlock = { context: Context ->
            val view =
                LayoutInflater.from(context)
                    .inflate(R.layout.my_layout, null, false)

            val textView = view.findViewById<TextView>(R.id.text)
            // do whatever you want...
            view // return the viw
        },
        update = { view ->
            // Update view
        }
    )
