底部導航抽屜在項目上顯示錯誤的圖標

Question

我正在處理“底部導航”抽屜通知，當我單擊“底部導航”的任何項目進行通知時，它在錯誤的項目上顯示圖標。 可以說，如果我單擊Item5並調用方法在此處顯示Notification，那么它將在Item1上顯示Notification項目。 下面給出了我的代碼以及屏幕快照。 我的片段類也如下所示：

MainActivity類：

 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();

    }

我的片段類：

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);
    }

}

單擊項目5，但通知圖標出現在我的通知抽屜項目的項目2中。

Answer 1

我已經檢查了您的代碼，並嘗試將其與AHBottomNavigation的 github repo進行比較 ，您猜怎么着？ 我發現了這個小錯誤。

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

現在檢查這一行，第一個參數是您的通知計數器，第二個參數是您的標簽號，您傳遞的是“ 1”，這意味着在“ 1”標簽上設置了通知標志，並且由於標簽計數器以零開頭，因此在第二個標簽。

答案很簡單。 只是用這個改變它

public static void setNotification(){
    bottomNavigation1.setNotification("1", 4);
}

Answer 2

當您這樣做時：

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

“ 1”是通知

1是項目位置

因此，您要在位置1的項目處設置通知：“菜單”

您可以做什么：

以這種方式修改方法：

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

}

然后，當您調用方法時：

setNotification("Any message or number", yourItemPostion)

示例：在設置中將“ 2”設置為：

setNotification("2", 4)
