How to collapse/expand widget code region/area in Compose Android Studio like in XML

Question

I have many Composables and I want to collapse Composable code inside like in xml. Is there extension for that?

Answer 1

Your post title is a bit misleading, but I think your'e asking how to collapse/expand "code" not the actual widget/ui.

I'm not sure if this is exactly what you want, but you can expand/collapse a specific area of your code if you wrap them within region/endregion without the need of any plugin or configuration, its almost the same behavior that your'e expecting from the xml editor, and you can do this anywhere not only to a function.

If you wish to make your Column collapse or expand without animation you simply need to add a if statement and set true to display false to collapse

var visible by remember { mutableStateOf(true) }

Column(modifier = Modifier.fillMaxSize()) {

    Text("Click to expand or collapse", modifier = Modifier
        .fillMaxWidth()
        .clickable {
            visible = !visible
        }
    )
    if(visible) {
      // Content to be collapsed or displayed
    }
}

If you wish to collapse or expand with animation you can check out AnimatedVisbility composable

var visible by remember {
    mutableStateOf(true)
}

Column(modifier = Modifier.fillMaxSize()) {

    Text("Click to expand or collapse", modifier = Modifier
        .fillMaxWidth()
        .clickable {
            visible = !visible
        }
    )
    AnimatedVisibility(visible = visible) {
        Column {
          // Content to be collapsed or displayed
        }
    }
}
