I am trying to use a BottomNavigationView with Android Navigation to create a standard tabbed application with three fragments: StatusFragment, MapFragment, and AlertsFragment.
I have my main_activity.xml with a FragmentContainerView and BottomNavigationView defined as follows:
<?xml version="1.0" encoding="utf-8"?>
My main_nav_graph.xml:
<?xml version="1.0" encoding="utf-8"?>
.ui.status.StatusFragment"
android:label="StatusFragment" />
.ui.map.MapFragment"
android:label="MapFragment" />
.ui.alert.AlertsFragment"
android:label="AlertsFragment" />
.ui.main.MainActivity"
android:label="main_activity"
tools:layout="@layout/main_activity" />
And the associated main_menu.xml:
<?xml version="1.0" encoding="utf-8"?>
In the onCreate method of my MainActivity, I configure navigation as follows:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.main_activity)
binding = MainActivityBinding.inflate(layoutInflater)
val navHostFragment = supportFragmentManager.findFragmentById(R.id.mainNavHostFragment) as NavHostFragment
val navController = navHostFragment.navController
val appBarConfiguration = AppBarConfiguration(
setOf(
R.id.statusFragment,
R.id.mapFragment,
R.id.alertsFragment
)
)
NavigationUI.setupActionBarWithNavController(this, navController, appBarConfiguration)
NavigationUI.setupWithNavController(binding.bottomNavigationView, navController)
}
The tab bar is displayed as expected, but tapping on the buttons does not do anything. I've made sure that the ids defined in main_menu.xml match those in main_nav_graph.xml. For being such a basic component of navigation on mobile, getting this to work on Android is proving to be frustratingly difficult; any help would be greatly appreciated.
