How to create a custom layout with AndroidView?. For some reason, the measured height of the AndroidView occupies all height. I checked, and it is the wrapper view that has that size. The real view has it’s size correct. Any help ?

What are the layout constraints coming into the AndroidView?

match_parent, wrap_content

That's the views layout params, what are the compost constraints?

fillMaxWidth, wrapContentHeight

Hm, I'd need to review how these interact bit wrapContentHeight with MATCH_PARENT sounds suspicious. From compose you're saying “just be whatever height you want” and then from the view you're saying “be as tall as possible”. But wrapContentHeight will by default only change the min constraint, not the max. I'm guessing AndroidView is going to use the max constraint for MATCH_PARENT.

I feel i am doing sth wrong. But i cannot figure out what.

Layout(content = {
    MyAndroidView(
        modifier = Modifier
            .fillMaxWidth()
            .wrapContentHeight()
    )

    Content()
}){ measurables, constraints ->

    val myAndroidViewPlaceable = measurables[0].measure(constraints)
    val contentPlaceable = measurables[1].measure(constraints)

    layout(constraints.maxWidth, constraints.maxHeight){
        myAndroidViewPlaceable.place(
            x = 0,
            y = 0
        )
        contentPlaceable.place(
            x = 0,
            y = myAndroidViewPlaceable.height
        )
    }
}

Oh yea, my bad. Literally just making my first coffee now 😅

i inspected the layout. The wrapper view that compose creates do take all the height. The real view, which is inside, takes the correct space. that’s what’s weird

One other note though, you might want to adjust the constraints for your content to account for the space taken up by the android view.

makes sense, ya. i’ll try

What are the constraints your layout is getting?

i changed the constraint for the androidview to

constraints.copy(minWidth = 0, minHeight = 0

and it correctly shows

Again, what are the constraints coming into your layout? 😜

no constraints. its Scafold content body

Every composable is measured with constraints

ya. i’ll investigate a bit. Thanks for the help
