Flutter: Keep BottomNavigationBar When Push to New Screen with Navigator

由 試著忘記壹切 提交于 2019-12-09 04:21:59

Inside screen A , there is a button. Tap that

BottomNavigationView does not hide on scrolling inside fragment, if fragment contains AppBarLayout

由 隐身守侯 提交于 2019-12-07 14:41:05
问题 I'm having a lot of problems with scrolling and detection of it inside fragments using coordinatorLayout in Android. I have a "MainActivity" that contains 3 fragments. In one of those fragments I have an Appbar that collapses when fragment is scrolled. I've managed to do that, but if I set scrolling behavior to allow that, my bottomNavigationView (which is found in mainactivity.xml) does NOT react to scrolling. Codes go something like this: Fragment1.xml <android.support.design.widget

Bottom Navigation loading Fragments is SLOW

由 孤者浪人 提交于 2019-12-05 06:26:27
I'm using a BottomNavigationView in my project and when I press an item and load e.g. My Ticket fragment, which generates a QR-code and takes a while, there is a huge delay until the item is selected. I tried to put an AsyncTask to load all data in onResume() and onActivityCreated() in the Fragment but it didn't work well. How can I use Bottom Navigation View and Fragments smoothly? BottomNavigationView bottomNavigationView = (BottomNavigationView) findViewById(R.id.bottom_navigation_view); Menu test = bottomNavigationView.getMenu(); test.add(Menu.NONE, 1, Menu.NONE, "Home").setIcon(R.drawable

I tried setting elevation from xml and programmatically both. But nothing works. It only works if you set white as android:background in the BottomNavigationView.
