Error inflating class on BottomNavigationView and style on this component requires your app theme to-CodePudding

I'm getting two errors, which probably relate to the BottomNavigationView in my DashBoardActivity. This only occurs for some users and not all.

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.adit.bangkit.plagroid/com.adit.bangkit.plagroid.ui.activities.DashboardActivity}: android.view.InflateException: Binary XML file line #8 in com.adit.bangkit.plagroid:layout/activity_dashboard: Binary XML file line #8 in com.adit.bangkit.plagroid:layout/activity_dashboard: Error inflating class com.google.android.material.bottomnavigation.BottomNavigationView

here is my dashboard activity:

class DashboardActivity : BaseActivity() {
private lateinit var binding: ActivityDashboardBinding

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    binding = ActivityDashboardBinding.inflate(layoutInflater)
    setContentView(binding.root)

    // Update the background color of the action bar as per our design requirement.
    supportActionBar!!.setBackgroundDrawable(
        ContextCompat.getDrawable(
            this@DashboardActivity,
            R.drawable.app_gradient_color_background
        )
    )
    // END

    val navView: BottomNavigationView = findViewById(R.id.nav_view)

    val navController = findNavController(R.id.nav_host_fragment)
    // Passing each menu ID as a set of Ids because each
    // menu should be considered as top level destinations.
    val appBarConfiguration = AppBarConfiguration(
        setOf(
            R.id.navigation_dashboard,
            R.id.navigation_orders,
            R.id.navigation_sold_products
        )
    )
    setupActionBarWithNavController(navController, appBarConfiguration)

    navView.setupWithNavController(navController)
}

override fun onBackPressed() {
    doubleBackToExit()
}
}

Here is my BottomNavigationView details:

    app:layout_constraintRight_toRightOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:navGraph="@navigation/mobile_navigation" />

</androidx.constraintlayout.widget.ConstraintLayout>

Line 8 in the error points to <com.google.android.material.bottomnavigation.BottomNavigationView. This is my layout for bottomNavigationView.

My application theme inherits from "Theme.MaterialComponents.Light.NoActionBar.Bridge".

Firstly, my bottom_nav_colours was in the drawable folder and it crashes for some users. Tried to duplicate it also in the existing drawable-any-dpi-v24 folder and it still crashes.

Not sure what to do here. I think the issue is to do with <com.google.android.material.bottomnavigation.BottomNavigationView in the activity_dashboard.

i've tried to update di library and re-checking all resources that used in layout but can't work. hope with this question it can be solved

CodePudding user response：

I had this issue too.. it seems like to be a bug.. Just change in xml:

<fragment
       .....

<androidx.fragment.app.FragmentContainerView
       .....

and in code instead of:

val navController = findNavController(R.id.nav_host_fragment)

val navHostFragment = supportFragmentManager.findFragmentById(R.id.nav_host_fragment) as NavHostFragment
val navController = navHostFragment.navController
