launchFragmentInHiltContainer does not work when using Jetpack Navigation #780

I had to change the method to use findNavController

aljohnston112 commented 3 years ago

I think the problem is android:launchMode="singleTop"

Here is my hack: inline fun <reified T : Fragment> launchFragmentInHiltContainer( navHost : Int, destFragment : Int, fragmentArgs: Bundle? = null, @StyleRes themeResId: Int = R.style.FragmentScenarioEmptyFragmentActivityTheme) { val startActivityIntent = Intent.makeMainActivity( ComponentName(ApplicationProvider.getApplicationContext(), ActivityMain::class.java)). putExtra(FragmentScenario.EmptyFragmentActivity.THEME_EXTRAS_BUNDLE_KEY, themeResId) ActivityScenario.launch<ActivityMain>(startActivityIntent).onActivity { activity -> activity.findNavController(navHost).navigate(destFragment, fragmentArgs) } } Not sure how good it is...

Here I set the graph and then perform navigation after the fact. inline fun <reified T : Fragment> launchFragmentInHiltContainer( navController: NavController, navHost: Int, navGraph: Int, ): ActivityScenario<ActivityMain> { val startActivityIntent = Intent.makeMainActivity( ComponentName( ApplicationProvider.getApplicationContext(), ActivityMain::class.java)) return ActivityScenario.launch<ActivityMain>(startActivityIntent).onActivity { activity -> val navHostFragment = activity.supportFragmentManager.findFragmentById(navHost) as NavHostFragment Navigation.setViewNavController(navHostFragment.requireView(), navController) navController.setGraph(navGraph) } }
