Jetpack navigation component 官网:https://developer.android.com/guide/navigation 即便在FragmentManager的文档里, 也建议开发者使用jetpack的navigation library来处理app的navigation. multiple back stack的支持是Navigation 2.4.0-a
假设被启动的activity已经执行在当前任务中,那么取代执行一个activity的新实例,在这个activity的上面的全部其他activity被销毁而且这个通过onNewIntent()给这个被又一次開始的activity的实例传递了这个intent。 没有launchMode属性值产生这样的行为。 FLAG_ACTIVITY_CLEAR_TOP是最长跟FLAG_ACTIVITY_NEW_TASK结合使用。当一起呗...
这个跟前面讨论的"singleTop"launchMode值产生同样的行为。 FLAG_ACTIVITY_CLEAR_TOP 假设被启动的activity已经执行在当前任务中,那么取代执行一个activity的新实例,在这个activity的上面的全部其他activity被销毁而且这个通过onNewIntent()给这个被又一次開始的activity的实例传递了这个intent。 没有launchMode属性值产生这样的...
为了比较不同的解决方案, 我把一些sample放在了一起:https://github.com/mengdd/bottom-navigation-samples Jetpack navigation component 官网:https://developer.android.com/guide/navigation 即便在FragmentManager的文档里, 也建议开发者使用jetpack的navigation library来处理app的navigation. multiple back stack的支持...
This sample provides an approach to separate back stack history for each tab in Bottom Navigation View using Android Navigation Architecture Component Bottom Navigation View gives the user quick access to 3-5 top-level destinations in an Android app. The common architectural approach for such a top...
在此过程中实现代码比较复杂混乱。为此，Jetpack提供了Navigation组件，方便我们管理页面和AppBar。
Implementation Note: As a best practice, when implementing either Home or Up, make sure to clear the back stack of any descendent screens. For Home, the only remaining screen on the back stack should be the home screen. For Up navigation, the current screen should be removed from the back...
可以看到,最终是通过registerAndStartActivity()来启动了intent,前面分析到mOverviewComponentObserver.getOverviewIntent()对应的就是mFallbackIntent,最终启动了RecentsActivity; 三、显示 在启动RecentsActivity后,会显示最近任务列表,看一下具体工作流程 1、RecentsActivity.java ...
