我有一个侦听器的公共静态数组列表，在每个活动中，我都在列表中添加一个新的侦听器，当我迭代调用列表中的每个侦听器时，没有一个活动得到remove调用，有人能告诉我我做错了什么吗？
（很抱歉英语不好...）
监听程序MealsListListener.class

public interface MealsListListener {
    void onMealAdded(Meal meal, int babyID);
    void onMealRemoved(Meal meal);
    void onMealChanged(Meal meal);
}

数组列表MealListListeners.class

public class MealListListeners {
    ArrayList<MealsListListener> mealsListListeners = new ArrayList<>();
    public MealListListeners() {
    }
    public void addMealsListListener(MealsListListener mealsListListener) {
        this.mealsListListeners.add(mealsListListener);
    }
    public void onMealAdded(Meal meal, int babyID) {
        for (MealsListListener mealsListListener : mealsListListeners) {
            mealsListListener.onMealAdded(meal, babyID);
        }
    }
    public void onMealRemoved(Meal meal){
        for (MealsListListener mealsListListener : mealsListListeners) {
            mealsListListener.onMealChanged(meal);
        }

    public void onMealChanged(Meal meal) {

从DialogMeal.class中的对话框调用

public class DialogMeal extends BottomSheetDialog {
    public DialogMeal(@NonNull Context context, Meal meal) {
        super(context);
        addNewMeal(meal);
        saveMealChanges(meal);
        removeMealAction(meal);
    }
    public void addNewMeal(Meal meal) {
        MainActivity.mealListListeners.onMealAdded(meal, 0);
    }
    private void saveMealChanges(Meal meal) {
        MainActivity.mealListListeners.onMealChanged(meal);
    }
    private void removeMealAction(Meal meal) {
        MainActivity.mealListListeners.onMealRemoved(meal);
    }
 }
