It presents a custom navigation controller that mirrors UINavigationController, manages child view controllers, and supports navigation transition animations and a navigation bar. ### Source excerpt Это вторая статья из цикла про bottom sheet, в которой мы воссоздаём поведение платёжного фрагмента в Кошельке по образу и подобию Apple Pay и сталкиваемся с тем, что это не так то просто. Из материала вы узнаете, как повторить полноценную навигацию в рамках bottom sheet отображения, основанного на autolayout, а не на неудобном ручном расчёте высоты. А ещё мы вместе повторим анимации навигационных переходов и добавим navigation bar как нативный способ управления навигацией.

It covers presentation and animation controllers, content-sized layout, and the example payment screen in the "Кошелёк" app. ### Source excerpt Современные требования к дизайну мобильных приложений всё чаще подкидывают задачи по отображению контента со сложным поведением. Для его реализации необходимо понимание того, как работают кастомные презентация и транзишены. В этой статье я расскажу, как мы решили задачу по созданию экрана оплаты в приложении "Кошелёк" с помощью кастомной навигации между контроллерами, которые отображаются как bottom sheet.

It uses child fragments, adding all tab fragments while detaching those that are not visible, and initializes each tab with its own navigation graph. ### Source excerpt It's been a recurring question, regardless of navigation framework of choice: how is it possible to create a screen with a bottom navigation view, that would host a navigation history stack per each tab? Each framework has its own unique ways. For example, with Jetpack Navigation you might use the NavigationExtensions, which requires you to host the BottomNavigationView at the Activity-level. But how would you do it with Jetpack Navigation, in such a way that the BottomNavigationView is confined to a single child fragment, and that child fragment would host all tabs that each have a NavController (backstack) available to them? How bottom navigation with child fragments normally works If you intend to create a BottomNavigationView that is hosted by a Fragment (and that Fragment hosts each tab as a child fragment), there's a bit of work needed to be done. To keep the fragments alive while switching between them, they must all be added. However, to make sure that the fragments are in the correct lifecycle (stopped while not showing), it makes sense to detach them (and attach the one that is meant to be showing). https://medium.com/media/82eb957284cfe5def31160ac33d277ba/href This example is also available here. Please note that there is nothing specific to Jetpack Navigation in this snippet, this is how a fragment can manage its child fragments and keep only one of them attached, while the rest are detached. We will use this knowledge later in the article. What Jetpack Navigation normally does When you use Jetpack Navigation (using its XML-based DSL) you typically create a navigation.xml (typically 1 per compilation module, but multiple nav graphs + include can be used too), which is then given to a NavHostFragment in a FragmentContainerView. This is what allows the NavController to be initialized with a graph, and save/restore its state. https://medium.com/media/4cc60fc3c96786f7f9adcbb3a1053853/hrefCreating a NavController and backstack for each bottom navigation tab T ## Creating a BottomNavigation Multi-Stack using child Fragments with Simple-Stack DevFeed: [Creating a BottomNavigation Multi-Stack using child Fragments with Simple-Stack]() Original publisher: [Read original article]() Author: Gabor Varadi Published: 2021-01-25T17:03:22Z Content type: tutorial Language: en Sources: [Stories by Gabor Varadi on Medium]() Topics: [navigation](), [Jetpack](), [configuration]() Tags: [android-app-development](), [bottom-navigation](), [bottomnavigationview](), [configuration](), [fragments](), [jetpack](), [jetpack-navigation](), [navigation](), [simple-stack]() ### AI overview A tutorial on implementing bottom navigation with a separate navigation history stack for each tab using child fragments and Simple-Stack. It explains fragment attachment and detachment, lifecycle management, and keeping back stacks alive across configuration changes. ### Source excerpt It's been a recurring question, regardless of navigation framework of choice: how is it possible to create a screen with a bottom navigation view, that would host a navigation history stack per each tab? Each framework has its own unique ways. For example, Jetpack Navigation provides NavigationExtensions as a sample, there's FragNav, but how would you do it with Simple-Stack? How bottom navigation with child fragments normally works If you intend to create a BottomNavigationView that is hosted by a Fragment (and that Fragment hosts each tab as a child fragment), there's a bit of work needed to be done. To keep the fragments alive while switching between them, they must all be added. However, to make sure that the fragments are in the correct lifecycle (stopped while not showing), it makes sense to detach them (and attach the one that is meant to be showing). https://medium.com/media/1667d9733c198c3ae611fd45504f6bd0/href This example is also available here. Please note that there is nothing specific to Simple-Stack in this snippet, this is how a fragment can manage its child fragments and keep only one of them attached, while the rest are detached. In fact, the NavigationAdvancedSample works the same way. We will use this knowledge later in the article. What Simple-Stack normally does When you use Simple-Stack, you typically install a Navigator using Navigator.install(). This allows a single global Backstack instance to be accessible through the Activity's context (and thus making it available to all views within the Activity), and provides automatic lifecycle management to ensure that navigation is handled correctly. https://medium.com/media/03bde713eca4e7ef47d7dae31f6e095d/href This is important to know, because if we want to create a Backstack for each Fragment within our BottomNavigationView, we must manage the lifecycle (and keep the Backstack instance alive across configuration changes) ourselves. Thankfully, this is actually quite simple to do!

It covers adding the dependency, configuring the view and menu items, and handling item-selection events. ### Source excerpt Sometimes in March 2016, Luke Wroblewski announced that the Bottom navigation bars were now a part of the material design guidelines. Until then, bottom nav bars were seen as an anti-pattern and were heavily kicked against. There have been several nice libraries to implement this bottom nav bar design, some of which include: https://github.com/roughike/BottomBar and https://github.com/aurelhubert/ahbottomnavigation. Just last week, Google (through Nick Butcher) announced the release of the v25 of the Android Design Support Library which includes the new BottomNavigationView. In this short post, I'll be showing how to use it in your Android app. If you are in a hurry, feel free to jump straight to look at the sample code here: https://github.com/segunfamisa/bottom-navigation-demo Setup To get started with this, you need the latest version (version 25) of Android SDK & tools (including SDK tools, build-tools, platform-tools, support repository). How to use it. 1. Add the design support library First step is to add the design support library to your app-level build.gradle file. Example is as shown below: dependencies { ... compile 'com.android.support:design:25.0.0' } 2. Add the BottomNavigationView to your layout Next step, is to add the actual bottom nav view to the layout. Typically, you will add something like: The BottomNavigationView uses design:menu is a custom attribute that points to the menu resource containing items to be shown on the BottomNavigationView. There are other custom attributes for the view, including: design:itemBackground to set the background of the menu resource design:itemIconTint to set the tint which is applied to the item icons. design:itemTextColor to set the menu item text colour. 3. Define the nav items in the menu
