I have two graphs, so the first graph move from one fragment to an activity passing safeArgs to the activity.
val action = MyFragmentDirections.actionMyActivity(arg1, arg2)
Navigation.findNavController(view).navigate(action)
Now in the second, I want to pass these arguments from MyActivity
to a fragment which belongs to this activity.
I can get the args:
val args = MyActivity.fromBundle(intent.extras)
The problem is there is not a Directions
file for this activity, so I can't pass the arguments.
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:
app:navGraph
attribute from your NavHostFragment
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).
