I.e., your navigation graph should instead look like:Īnd your menu XML should be updated to use to match your navigation graph. If you want to link R.id.frag_hint to your Home tab, then that's exactly what a nested navigation graph can be used for. So what you're seeing in your sample app is that there's no link between R.id.frag_hint and any menu item, which means NavigationUI does nothing. In the Navigation 2.3.5, there was no state saved for each tab, so it only 'worked' because selecting a tab forced the ID of the current destination to match the destination of the menu item you just tapped. So what is different when you tap on a bottom navigation item? Well, nothing different from a NavigationUI perspective in fact: the exact same code runs and the current destination and what graph it is part of is the source of truth for what tab should be selected. That is true on all versions of Navigation. There's no menu item that matches that ID either, so NavigationUI can't associated that destination with any menu item and therefore simply does nothing. It then looks at the destination's parent graph - your R.id.sample element. It looks at that NavDestination and notes that there's no menu item that matches R.id.frag_hint. So when you navigate() to R.id.frag_hint via your button in HomeFragment, NavigationUI receives a callback that the current destination has changed to R.id.frag_hint. This can be seen by calling navigate() to go to your SecondFragment - even though you haven't used the bottom nav button, the selected tab was changed because the current destination has changed to R.id.frag_second. ![]() NavigationUI has always used the current destination and what graph it is part of as the source of truth for what tab should be selected. So bekommen Sie automatisch eine Nachricht, wenn die neueste Ausgabe Ihrer abonnierten Sendung in der Mediathek verfügbar ist.Given your navigation graph, there is no way to associate fragmentA2 with your menu item fragmentA, so fragmentA is not selected when you return to fragmentA2.
