Can we use setContentView which is responsible to load xml layout and setContent in single activity class ?

[Luca Nicoletti]

setContent is calling setContentView internally so it will override it

[Luca Nicoletti]

Up to you, the second one called will be the one you’ll see

[amar_1995]

So is it possible to add old xml layout and on top of it add compose ui.

[Luca Nicoletti]

No, that's not what overrides means

[Michal Bacik]

I've read somewhere that there will be @GenerateView annotation that will generate a view from @Composable function, then you'll be able to mix compose with classic view hierarchy.

[Luca Nicoletti]

But you won't be able to use setcontent and setcontentview all together

[Michal Bacik]

That's true, compose internally uses setcontentview for its own working view.

[amar_1995]

So, suppose we have some old android project based on layout xml and we want to integrate it with compose. Then, we can only create new view in compose or replace old layout xml with new compose ui.

[Michal Bacik]

You should be able to integrate compose at various levels. Maybe replace entire UI for Activity, or implement just specific views as compose items.

[amar_1995]

setContentView(R.layout.main_login)
        setContent {
            MaterialTheme(
                colors = lightThemeColors,
                typography = themeTypography
            ) {
                MonitorScreenCompose(id, applicationContext, this)
            }
        }

In above code there is one layout and other one is compose ui. I want to first display layout from xml and below that layout, I want to add compose ui.
Is it possible ?

[Luca Nicoletti]

No.

[amar_1995]

Okay

[Luca Nicoletti]

override does not mean add to bottom

[Adam Powell]

There's a version of setContent as a ViewGroup extension that you can try out

[Luca Nicoletti]

Yep, that would work, it’s accepting the rootView in which it will ” _inflate_” the composable function, right?

[Adam Powell]

Yeah. It'll add the compose host view to the ViewGroup you supply

[amar_1995]

@Adam Powell Is there any demo on how to add compose host view to the viewGroup ?
