Navigation Component: pass safeArgs from activity to a fragment
Navigation 1.0.0-alpha07 fixed the feature request for passing arguments to the start destination of a graph.
To use this, you'd need to:
- Remove the
app:navGraph
attribute from yourNavHostFragment
- Call
findNavController(R.id.your_nav_host_fragment).setGraph(R.navigation.your_graph, intent.extras)
Using the R.id
of your NavHostFragment
and R.navigation
that you previously had on your app:navGraph
tag. By passing the arguments into the setGraph
call, your starting destination will get the arguments directly, without calling navigate
again (which would, by default, create a new instance of the destination on your back stack - not what you want).
I don't know if this is recommended, but it is working:
val args = MyActivity.fromBundle(intent.extras)
navController.navigate(R.id.myActivityFragment, args.toBundle())
