I'm creating an application where it uses the Navigation Architecture, but my navigation has no default host, and can be set based on the selected destination by the user.
So this is the setup of my NavHostFragment
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
var finalHost: NavHostFragment? = null
when (bundle) {
REQUEST_FIRST -> {
finalHost = NavHostFragment.create(R.navigation.navigation_first)
}
REQUEST_SECOND -> {
finalHost = NavHostFragment.create(R.navigation.navigation_second)
}
REQUEST_THIRD -> {
finalHost = NavHostFragment.create(R.navigation.navigation_third)
}
}
supportFragmentManager.beginTransaction()
.replace(R.id.fragmentMain, finalHost!!)
.setPrimaryNavigationFragment(finalHost)
.commit()
}
and this is my main activity layout.
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/black">
<!-- some stuff -->
<fragment
android:id="@+id/fragmentMain"
android:name="androidx.navigation.fragment.NavHostFragment"
android:layout_width="0dp"
android:layout_height="0dp"/>
</androidx.constraintlayout.widget.ConstraintLayout>
So, my MainActivity
is loading correctly but when I start to rotate the screen of the device, It encounters some errors.
java.lang.RuntimeException: Unable to start activity ComponentInfo: android.view.InflateException: Binary XML file line #10: Binary XML file line #10: Error inflating class fragment
the said error is pointing on my setContentView(R.layout.activity_main)
and the NavHostFragment <fragment>
in layout.
any help is appreciated, Thanks!
