无法隐藏包含 SharedPreferences 值的文本视图

Question

我正在尝试隐藏对 SharedPreferences 有价值的文本视图，但它根本不起作用。

这是我的代码的一部分，它从 SharedPreferences 获取值并将其设置为文本视图

private void CheckChart() {
        Order1 order1 = sharedPrefmanager.getInstance(getActivity()).GetOrder1();
        Order2 order2 = sharedPrefmanager.getInstance(getActivity()).GetOrder2();
        CartStatus CheckCartStats = sharedPrefmanager.getInstance(getActivity()).GetCartStatus();
        if (order1.getFoodName() == "null"){
            LinearLayoutCartOrder1.setVisibility(GONE);
        }
        else {
            if (CheckCartStats.getCart1Status() == "Full"){
                LinearLayoutCartOrder1.setVisibility(View.VISIBLE);
//                Cart1Status = "full";
                //Fill the cart 1
                 order1 = sharedPrefmanager.getInstance(getActivity()).GetOrder1();
                //Food
                FoodCode = order1.getFoodCode();
                FoodName = order1.getFoodName();
                FoodCount = order1.getFoodCount();
                FoodTotalPrice = order1.getFoodTotalPrice();
                FoodType = order1.getFoodType();
                //Topping Name
                ToppingName1 = order1.getToppingName1();
                ToppingName2 = order1.getToppingName2();
                ToppingName3 = order1.getToppingName3();
                ToppingName4 = order1.getToppingName4();
                ToppingName5 = order1.getToppingName5();

                ToppingPrice1 = order1.getToppingPrice1();
                ToppingPrice2 = order1.getToppingPrice2();
                ToppingPrice3 = order1.getToppingPrice3();
                ToppingPrice4 = order1.getToppingPrice4();
                ToppingPrice5 = order1.getToppingPrice5();
                ToppingPrice6 = order1.getToppingPrice6();
                ToppingPrice7 = order1.getToppingPrice7();
                ToppingPrice8 = order1.getToppingPrice8();
                ToppingPrice9 = order1.getToppingPrice9();
                ToppingPrice10 = order1.getToppingPrice10();
                //Total Price
                TotalPrice = order1.getTotalPrice();

                //If the food is without type then Visibility to food type is gone
                if (FoodType == "null"){
                    TxtvCart1FoodCount.setText(FoodCount);

                    RemoveViewForUnusedTopping();
                }
                else {

                }
            }

    }

这是从 SharedPreferences

中隐藏默认值为“null”的未使用浇头的函数

private void RemoveViewForUnusedTopping() {

        //Make Unused View Topping Dissapear

无论我做什么，未使用的浇头都不会 GONE 我已经尝试将 RemoveViewForUnusedTopping() 功能放在按钮上并按下它仍然无法正常工作。是否真的可以隐藏设置了 SharedPreferences 值的 TextView？

在更改为 Equal() 后已修复它并按照 Textview 分隔 if 语句并将其从“null”更改为“none”

private void RemoveViewForUnusedTopping() {
        Order1 order1 = sharedPrefmanager.getInstance(getActivity()).GetOrder1();
