androidx.navigation.fragment

Kotlin |Java

Classes

DialogFragmentNavigator	Navigator that uses `DialogFragment#show(FragmentManager, String)`.
DialogFragmentNavigatorDestinationBuilder	DSL for constructing a new DialogFragmentNavigator.Destination
FragmentNavigator	Navigator that navigates through `fragment transactions`.
FragmentNavigatorDestinationBuilder	DSL for constructing a new FragmentNavigator.Destination
NavHostFragment	NavHostFragment provides an area within your layout for self-contained navigation to occur.

FragmentNavigatorExtras(vararg sharedElements: Pair<View, String>)

Create a new FragmentNavigator.Extras instance with the given shared elements

For NavGraphBuilder
Unit	`NavGraphBuilder.dialog(@IdRes id: Int)` Construct a new DialogFragmentNavigator.Destination
Unit	`NavGraphBuilder.dialog(@IdRes id: Int, builder: DialogFragmentNavigatorDestinationBuilder.() -> Unit)` Construct a new DialogFragmentNavigator.Destination
Unit	`NavGraphBuilder.fragment(@IdRes id: Int)` Construct a new FragmentNavigator.Destination
Unit	`NavGraphBuilder.fragment(@IdRes id: Int, builder: FragmentNavigatorDestinationBuilder.() -> Unit)` Construct a new FragmentNavigator.Destination

For Fragment
NavController	`Fragment.findNavController()` Find a NavController given a Fragment
NavArgsLazy<Args>	`Fragment.navArgs()` Returns a Lazy delegate to access the Fragment's arguments as an Args instance.

fun FragmentNavigatorExtras(vararg sharedElements: Pair<View, String>): FragmentNavigator.Extras

Create a new FragmentNavigator.Extras instance with the given shared elements

Parameters
`sharedElements`	One or more pairs of View+String names to be passed through to FragmentNavigator.Extras.Builder.addSharedElement.

inline fun <reified F : DialogFragment> NavGraphBuilder.dialog(@IdRes id: Int): Unit

inline fun <reified F : DialogFragment> NavGraphBuilder.dialog(@IdRes id: Int, builder: DialogFragmentNavigatorDestinationBuilder.() -> Unit): Unit

fun Fragment.findNavController(): NavController

Calling this on a Fragment that is not a NavHostFragment or within a NavHostFragment will result in an IllegalStateException

inline fun <reified F : Fragment> NavGraphBuilder.fragment(@IdRes id: Int): Unit

inline fun <reified F : Fragment> NavGraphBuilder.fragment(@IdRes id: Int, builder: FragmentNavigatorDestinationBuilder.() -> Unit): Unit

@MainThread inline fun <reified Args : NavArgs> Fragment.navArgs(): NavArgsLazy<Args>

Returns a Lazy delegate to access the Fragment's arguments as an Args instance.

It is strongly recommended that this method only be used when the Fragment is created by androidx.navigation.NavController.navigate with the corresponding androidx.navigation.NavDirections object, which ensures that the required arguments are present.


class MyFragment : Fragment() {
    val args: MyFragmentArgs by navArgs()
}

This property can be accessed only after the Fragment's constructor.
