Question

我正在处理底部导航抽屉通知，当我点击底部导航的任何项目进行通知时，它会在错误的项目上显示图标。让我们说如果我点击Item5并调用方法在那里显示Notification，那么它将显示Item1上的Notification项。下面给出了我的代码，以及我的屏幕快照。我的片段类也在下面给出：

MainActivity类：

 AHBottomNavigation bottomNavigation;
    Fragment selectedFragment = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        bottomNavigation = (AHBottomNavigation) findViewById(R.id.navigation);

        AHBottomNavigationItem item1 = new AHBottomNavigationItem(R.string.home,     R.drawable.home, R.color.colorAccent);
        AHBottomNavigationItem item2 = new AHBottomNavigationItem(R.string.menu,     R.drawable.menu, R.color.colorAccent);
        AHBottomNavigationItem item3 = new AHBottomNavigationItem(R.string.cart,     R.drawable.cart, R.color.colorAccent);
        AHBottomNavigationItem item4 = new AHBottomNavigationItem(R.string.orders,   R.drawable.orders, R.color.colorAccent);
        AHBottomNavigationItem item5 = new AHBottomNavigationItem(R.string.settings, R.drawable.setting, R.color.colorAccent);

        bottomNavigation.addItem(item1);
        bottomNavigation.addItem(item2);
        bottomNavigation.addItem(item3);
        bottomNavigation.addItem(item4);
        bottomNavigation.addItem(item5);

        bottomNavigation.setTitleState(AHBottomNavigation.TitleState.ALWAYS_SHOW);
        bottomNavigation.setAccentColor(Color.parseColor("#571e19"));

//        selectedFragment = ItemHomeFragment.newInstance(bottomNavigation);

        bottomNavigation.setOnTabSelectedListener(new AHBottomNavigation.OnTabSelectedListener() {
            @Override
            public boolean onTabSelected(int position, boolean wasSelected) {

                if (position == 0) {
                    selectedFragment = ItemHomeFragment.newInstance(bottomNavigation);
                } else if (position == 1) {
                    selectedFragment = ItemMenuFragment.newInstance(bottomNavigation);
                } else if (position == 2) {
                    selectedFragment = ItemCardFragment.newInstance(bottomNavigation);
                } else if (position == 3) {
                    selectedFragment = ItemOrdersFragment.newInstance(bottomNavigation);
                } else if (position == 4) {
                    selectedFragment = ItemSettingsFragment.newInstance(bottomNavigation);
                }

                android.app.FragmentManager fragmentManager = getFragmentManager();
                android.app.FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                fragmentTransaction.replace(R.id.frame_layout,selectedFragment);
                fragmentTransaction.commit();


                return true;

            }

        });

    }

    @Override
    protected void onStart() {
        super.onStart();
        android.app.FragmentManager fragmentManager = getFragmentManager();
        android.app.FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        fragmentTransaction.replace(R.id.frame_layout, ItemHomeFragment.newInstance(bottomNavigation));
        fragmentTransaction.commit();

    }

My Fragment Class：

public class ItemSettingsFragment extends Fragment {

    public static AHBottomNavigation bottomNavigation1;

    public static ItemSettingsFragment newInstance(AHBottomNavigation bottomNavigation) {
        ItemSettingsFragment fragment = new ItemSettingsFragment();
        // Initializing Navigation Drawer
        bottomNavigation1 = bottomNavigation;
        return fragment;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {


        View view = inflater.inflate(R.layout.fragment_settings, container, false);

        setNotification();
        return view;

    }


    // Calling this method in my 5 Item of Notification Drawer, but '1' is showing in first item of Bottom Noficiation drawer
    public static void setNotification(){
        bottomNavigation1.setNotification("1", 1);
    }

}

点击Item5但通知图标出现在我的Notification Drawer项目的Item2中。

Answer 1

我已经检查了你的代码并尝试比较它与github repo AHBottomNavigation 并猜测是什么？我发现这个小错误。

chars = set("!$%^&*()_-+=")

if any((i in chars) for i in string):
  points += 1

现在检查此行，第一个参数是您的通知计数器，第二个参数是您的标签号，您正在通过＆＃39; 1＆＃39;这意味着在＆＃39; 1＆＃39;上设置通知徽章选项卡，因为制表符计数器从零开始，这就是它在第二个选项卡上设置的原因。

回答很简单。只需更改即可

public static void setNotification(){
    bottomNavigation1.setNotification("1", 1);
}

Answer 2

当你这样做时：

   public static void setNotification(){
    bottomNavigation1.setNotification("1", 1);
}

＆＃34; 1＆＃34;是通知

1是项目位置

因此，您要在位置1处的项目处设置通知：＆＃34;菜单＆＃34;

你能做什么：

以这种方式修改方法：

   public static void setNotification(String notification, int itemPostion){
bottomNavigation1.setNotification(motification, itemPostion);

}

然后，当你调用方法时：

setNotification("Any message or number", yourItemPostion)

示例：在设置上设置＆＃34; 2＆＃34;

setNotification("2", 4)

底部导航抽屉显示项目上的错误图标
