I updated to compileSdkVersion 31
and now when tapping on a BottomNavigationView
item it does not always highlight the icon or show the fragment the BottomNavigationView
item id points to.
There are 3 bottom navigation tabs called Home
, Actions
, My Progress
. From the Home
fragment, you can navigate to SubFragment
.
So the flow might be to start at Home
--> go to SubFragment
--> go to Actions
with the BottomNavigationView
--> and then tap on Home
to go back. What this did before the update was open the Home
fragment (desired behavior). Now when tapping on the Home icon it shows SubFragment
and does not highlight the icon.
More details
This is the navController setup:
bottomNavigationView = findViewById(R.id.bottom_navigation_view)
val navHostFragment = supportFragmentManager.findFragmentById(R.id.nav_host_fragment) as NavHostFragment
val navController = navHostFragment.navController
bottomNavigationView.setupWithNavController(navController)
The nav_graph
structure is like this:
<fragment
android:id="@+id/home"
android:name="com.example.app.home"
android:label="Home"
tools:layout="@layout/home"
<action
android:id="@+id/action_home_fragment_to_sub_fragment"
app:destination="@id/sub_fragment"/>
</fragment>
<fragment
android:id="@+id/subfragment"
android:name="com.example.app.subfragment"
android:label="Sub Fragment"
tools:layout="@layout/subfragment" />
<fragment
android:id="@+id/actions"
android:name="com.example.app.actions"
android:label="Actions"
tools:layout="@layout/actions" />
<fragment
android:id="@+id/myprogress"
android:name="com.example.app.myprogress"
android:label="My Progress"
tools:layout="@layout/myprogress" />
The menu items id's for the BottomNavigationView
are identical to nav_graph
.
I thought the issue might be with the nav_graph
structure not playing well with the new SDK, so I tried adjusting the structure of the nav_graph
so that each navigation tab was within its own like this question answer has setup. It highlights the tab with this approach but still does not navigate to Home
like the example above. Only to SubFragment
.
Ideas on what I might be missing are appreciated!
