let's say I have fragments a->b->c , but "a" is a splash screen, so I want "b" to become first fragment in stack and throw "a" forever, so when I'm i "b" and press "back" system button - I close the app
In SupportFragmentManager I used replace() and that worked. But how can I achieve it here?
here is an example
graph.xml
<?xml version="1.0" encoding="utf-8"?>
<navigation 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"
app:startDestination="@id/splashFragment">
<fragment
android:id="@+id/splashFragment"
android:name="com.example.***.fragments.SplashFragment"
android:label="SplashFragment"
tools:layout="@layout/layout_splash">
<action
android:id="@+id/action_splashFragment_to_homeFragment"
app:destination="@id/homeFragment"
app:popUpTo="@id/splashFragment"
app:popUpToInclusive="true"/> // here to make home fragment as root
</fragment>
<fragment
android:id="@+id/homeFragment"
android:name="com.example.***.fragments.HomeFragment"
android:label="HomeFragment"
tools:layout="@layout/layout_home">
</fragment>
</navigation>
and in SplashFragment you just need to navigate to Home in OnCreate()
findNavController().navigate(R.id.action_splashFragment_to_homeFragment)
also if you want to do this in code only
findNavController()
.navigate(R.id.action_splashFragment_to_homeFragment,
null,
NavOptions.Builder()
.setPopUpTo(R.id.splashFragment,
true).build()
)
