created issue #1

Jun 18, 2018 05:31PM

Component used: Navigation graph
Version used: 1.0.0-alpha01
Devices/Android versions reproduced on: Device running Android P, compiled in SDK 27

If this is a bug in the library, we would appreciate if you could attach:
- Sample project to trigger the issue.
- A screenrecord or screenshots showing the issue (if UI related).

In order to instantiate the view of my first fragment, some data needs to be passed from the current Activity to the primary fragment. Currently, I don't see a clear way to do this. In the same way one can navigate from fragment to fragment while passing arguments via the NavController's navigate method, it would be helpful if there was some method to pass a bundle to the first nav fragment and update the graph associated with the NavHostFragment before inflating the view.

Please do let me know if there is some way to do this that I'm missing. Currently I'm setting up a dummy fragment to start with that will manage passing the data to the intended first fragment.

Allow passing arguments to the start destination

Make an explicit mechanism for passing a Bundle
of arguments to the start destination of the
navigation graph when calling setGraph() or
NavHostFragment.create().

It is still up to the developer to specifically
construct that Bundle. This is to prevent the
potential arbitrary Intent extras (which may
have been crafted maliciously) to enter the
Fragment arguments (which should be trusted).

Test: new tests in runtime and fragment

Marked as fixed.

Passing arguments to the start destination can now be done via

NavHostFragment.create(R.navigation.graph, args)
or
navController.setGraph(R.navigation.graph, args)
or
navController.setGraph(navGraph, args)

This will be available in alpha07

Version used: 1.0.0-rc02
Devices/Android versions reproduced on: Device running Android P, compiled in SDK 28
Marked as fixed.

1.declare NavHostFragment with id
2. Inflate the container
3. declare navGraph with id
4.Extract from Intent
5. val navArgument= NavArgument.Builder().setDefaultValue("Required Bundle").build()
6.Add argument with graph

val navHostFragment = container as NavHostFragment
val inflater = navHostFragment.navController.navInflater
val graph = inflater.inflate(R.navigation.wash_request)

var place : String = intent?.getStringExtra("place") as String
var latlong : String = intent?.getStringExtra("latlong") as String
var selectCar = CarWashDetail(place,latlong)

val navArgument= NavArgument.Builder().setDefaultValue(selectCar).build()
graph.addArgument("CarWashDetails",navArgument)

navHostFragment.navController.graph = graph
