I m trying to wrap my head around this I have an observable

Question

I m trying to wrap my head around this I have an observable come back with the data to make a Profile page however I have to make a second call to display more data to the user afterwards How could I react when the second set of data comes back and add that to the tree Example ``` Composable Profile username String name String location String activityTotals List lt ActivityTotals gt = null ``` The `activityTotals` come back afterwards Since `Profile` isn t an object I can t expose a property to update with the new value Would I expose a state or pass in an observable or do something else

Can you show the code that calls this so far

```viewModel detailedAthlete observe viewLifecycleOwner Observer athlete gt profilezone setContent Profile athlete username athlete name athlete location ```

Hadn t gotten there yet was trying to figure it out because I m mixing compose in with a fragment that has other views But I m thinking it would be something like that

chris · Answer

There would be a second observable for the other call on the viewModel

Adam Powell · Answer

Compose works a bit differently from that a composable function doesn t return a `View` and may only be called by another composable function Analogous code from a ` Composable` caller might look something like this ```val athlete by viewModel detailedAthlete observeAsState Profile athlete username athlete name athlete location ```

Adam Powell · Answer

Compose will re evaluate the function body when the input data changes in this case when the state being observed changes

chris · Answer

I could add the Composable to a fragment with `ViewGroup setViewContent` right edit I see it s going away Never mind

Adam Powell · Answer

You probably want the `ViewGroup setContent` extension rather than `setViewContent` for now but yes You ll want to call that extension on a `FrameLayout` or similar since `ViewGroup setContent` doesn t give you much control over the child `LayoutParams` or ordering

The model is quite different at first but it starts paying off quickly slightly smiling face
