我如何将我的BottomNavigationView与导航抽屉结合在一起

Question

当我在应用程序中同时使用BottomNavigationView和NavigationDrawer时但是当我在两个按钮（BottomNavigationView和NavigationDrawer）中都放置Home按钮时，会出现问题，导航抽屉的按钮工作正常，但是当使用BottomNavigationView中的Home（仪表板）时，当我单击任何一个卡片视图时都会出现问题从BottomNavigationView选择“主页”后，cardView会崩溃，但是当我从NavigationDrawer中打开它时，它运行良好。

这里是错误：

java.lang.IllegalArgumentException：导航目标com.appsnipp.admin：id / action_nav_home_to_nav_resource对于此NavController未知

从BottomNavigationView BottomNavigationView的主页查看

导航抽屉Navigation Drawer这是我的密码！

        layoutParams.setBehavior(new BottomNavigationBehaviour());

        bottomNavigationView.setSelectedItemId(R.id.navB_home);
        navigationView=findViewById(R.id.nav_view);
        navigationView.setCheckedItem(R.id.nav_home);

        // Passing each menu ID as a set of Ids because each
        // menu should be considered as top level destinations.
        mAppBarConfiguration = new AppBarConfiguration.Builder(
                R.id.nav_home, R.id.nav_account, R.id.nav_member,

        }
    });
    return root;
}
}

让我知道是否需要其他文件代码。

预先感谢！

Answer 1

所以问题出在我在导航文件中以nav_home navB_home创建了一个重复片段的地方，但是在导航时我总是从nav_home导航。因此，为了解决这个问题，我从导航和菜单中删除了navB_home，在那里充气nav_home（BottomNavigationView）因此，目前NavigationView和BottomNavigationView的片段导航与nav_home相同。
