If the menu item is not meant to navigate, handle with super.onOptionsItemSelected. Traditionally you would use an intent-filter and associate a URL with the activity you want to open. The click listener code would look like this: Each navigate() call has a not very exciting default transition associated with it, as seen below: The default transition, as well as other attributes associated with the call, can be overridden by including a set of NavOptions. If you need to download a recent version of Android Studio, you can do so here. All of the changes you make in the graphical Navigation Editor change the underlying XML file, similar to the way the Layout Editor modifies the layout XML.

Drag an arrow from home_dest to flow_step_one_dest: 3. In this step, you'll add a brand new destination. 5. A NavHostFragment swaps different fragment destinations in and out as you navigate through the navigation graph. Android Navigation between fragments using backstack and static fabric pattern Example First of all, we need to add our first Fragment at the beginning, we should do it in the onCreate() method of our Activity: Finally, let's use NavigationUI to configure the side navigation and navigation drawer, including handling the ActionBar and proper up navigation. You can override this behavior by passing in an activity as the context or set an explicit activity class via setComponentName(). The result is a new destination, which renders a preview of the fragment's layout in the design view. 2. However if if change the current Fragment via the Navigation Drawer and then press back the app always returns to the start Fragment of the Navigation Graph. It's better to use safe args. The purpose of AppBarConfiguration is to specify the configuration options you want for your toolbars, collapsing toolbars, and action bars. The backstack for a deep link is determined using the navigation graph you pass in. In this codelab you learned about: You can continue to explore with this app or start using navigation in your own app. Verify that tapping the Navigate To Destination button causes the fragment to slide onto the screen and that pressing back causes it to slide off the screen. This will do the following: 5. Google has recently announced various android libraries to introduce some best practices in the world of android during I/O 2018. Create an AppBarConfiguration by passing in a set of top-level destination IDs and the drawer layout. Good work! URIs without a scheme are assumed to be http and https. Now the navigation view menu will show on the screen, but it will not affect the ActionBar. Double click app-debug.apk to open in APK Analyzer. Open the app/build.gradle file and notice the applied plugin: 3. One of the most common uses of a deep link is to allow a web link to open an activity in your app. You'll learn more about actions later. The sample app starts with a few destinations in the graph. It should say "From Widget" at the top since that is the argument you passed in DeepLinkAppWidgetProvider. 4. To build a multi pane User Interface, you can combine multiple fragments in a single activity. 7. If the explicit Activity you've chosen has a parent activity, those parent Activities are also included. The common architectural approach for such a top level navigation which is provided by the Android navigation component is that activity only knows one backstack. With the action arrow selected (blue) change the properties of the action so that: Note the newly added next_action action under the home_dest destination: 6. Since we have finished our first navigation, lets get to the more specific stuff! Press question mark to learn the rest of the keyboard shortcuts. This was passed through to the fragment, from the URL. The navigation library makes this extremely simple and allows you to map URLs directly to destinations in your navigation graph. You should also have NavigationUI handle what happens when the Up button is pressed. Since the XML includes an argument called flowStepNumber, specified by android:name="flowStepNumber", the generated class FlowStepFragmentArgs will include a variable flowStepNumber with getters and setters. Implement the setupNavigationMenu method using setupWithNavController(navigationView: NavigationView, navController: NavController). Tags: The arrows between the destinations are called actions. Open the mobile_navigation.xml file in Design mode. Fragment is a modular section of any activitywhich has its own lifecycle, receives its own input events, and which you can add or remove while the activity is running (sort of like a sub activity that you can reuse in different activities).

NavigationUI has static methods that associate menu items with navigation destinations, and navigation-ui-ktx is a set of extension functions that do the same. Heres how to do it. Note that the start destination is always considered a top-level destination. Open res/layout/navigation_activity/navigation_activity.xml (h470dp) and click the Text tab, Notice how the XML layout code for bottom navigation is there and refers to bottom_nav_menu.xml. Open res/navigation/mobile_navigation.xml, and click the Design tab. But in some cases you need to have different back stack history for each tab in bottom navigation view like Instagram app. When you're finished, you'll have a deep link widget. Android Development, You should have a functional ActionBar menu that navigates to the SettingsFragment. In comparison, fragments will be the actual destination-specific layouts.

If you do not then you must pass the argument into the action, as shown:HomeFragmentDirections.nextAction(flowStepNumberArg).
