无法隐藏包含"共享首选项"中的值的文本视图

Question

我试图隐藏具有SharedPreferences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();
ToppingName6 = order1.getToppingName6();
ToppingName7 = order1.getToppingName7();
ToppingName8 = order1.getToppingName8();
ToppingName9 = order1.getToppingName9();
ToppingName10 = order1.getToppingName10();
//Topping Price
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);
TxtvCart1FoodName.setText(FoodName);
TxtvCart1FoodPrice.setText(FoodTotalPrice);
TxtvCart1FoodType.setText(FoodType);
TxtvCart1FoodType.setVisibility(GONE);
TxtvCart1Topping1.setText(ToppingName1);
TxtvCart1Topping2.setText(ToppingName2);
TxtvCart1Topping3.setText(ToppingName3);
TxtvCart1Topping4.setText(ToppingName4);
TxtvCart1Topping5.setText(ToppingName5);
TxtvCart1Topping6.setText(ToppingName6);
TxtvCart1Topping7.setText(ToppingName7);
TxtvCart1Topping8.setText(ToppingName8);
TxtvCart1Topping9.setText(ToppingName9);
TxtvCart1Topping10.setText(ToppingName10);
TxtvCart1ToppingPrice1.setText(ToppingPrice1);
TxtvCart1ToppingPrice2.setText(ToppingPrice2);
TxtvCart1ToppingPrice3.setText(ToppingPrice3);
TxtvCart1ToppingPrice4.setText(ToppingPrice4);
TxtvCart1ToppingPrice5.setText(ToppingPrice5);
TxtvCart1ToppingPrice6.setText(ToppingPrice6);
TxtvCart1ToppingPrice7.setText(ToppingPrice7);
TxtvCart1ToppingPrice8.setText(ToppingPrice8);
TxtvCart1ToppingPrice9.setText(ToppingPrice9);
TxtvCart1ToppingPrice10.setText(ToppingPrice10);
TxtvCart1TotalPrice.setText(TotalPrice);
RemoveViewForUnusedTopping();
}
else {
TxtvCart1FoodCount.setText(FoodCount);
TxtvCart1FoodName.setText(FoodName);
TxtvCart1FoodPrice.setText(FoodTotalPrice);
TxtvCart1FoodType.setText(FoodType);
TxtvCart1Topping1.setText(ToppingName1);
TxtvCart1Topping2.setText(ToppingName2);
TxtvCart1Topping3.setText(ToppingName3);
TxtvCart1Topping4.setText(ToppingName4);
TxtvCart1Topping5.setText(ToppingName5);
TxtvCart1Topping6.setText(ToppingName6);
TxtvCart1Topping7.setText(ToppingName7);
TxtvCart1Topping8.setText(ToppingName8);
TxtvCart1Topping9.setText(ToppingName9);
TxtvCart1Topping10.setText(ToppingName10);
TxtvCart1ToppingPrice1.setText(ToppingPrice1);
TxtvCart1ToppingPrice2.setText(ToppingPrice2);
TxtvCart1ToppingPrice3.setText(ToppingPrice3);
TxtvCart1ToppingPrice4.setText(ToppingPrice4);
TxtvCart1ToppingPrice5.setText(ToppingPrice5);
TxtvCart1ToppingPrice6.setText(ToppingPrice6);
TxtvCart1ToppingPrice7.setText(ToppingPrice7);
TxtvCart1ToppingPrice8.setText(ToppingPrice8);
TxtvCart1ToppingPrice9.setText(ToppingPrice9);
TxtvCart1ToppingPrice10.setText(ToppingPrice10);
TxtvCart1TotalPrice.setText(TotalPrice);
RemoveViewForUnusedTopping();

}
}
}
}

并且这里是隐藏具有默认值"Unused Topping"的函数；空"；来自SharedPreferences

private void RemoveViewForUnusedTopping() {
Order1 order1 = sharedPrefmanager.getInstance(getActivity()).GetOrder1();
//Make Unused View Topping Dissapear
//Topping 1
if (order1.getToppingName1() == "null"){
TxtvCart1Topping1.setVisibility(GONE);
TxtvCart1ToppingPrice1.setVisibility(GONE);
TxtvRp1.setVisibility(GONE);
}
else if(order1.getToppingName1() != "null"){
//Topping 1
TxtvCart1Topping1.setVisibility(VISIBLE);
TxtvCart1ToppingPrice1.setVisibility(VISIBLE);
TxtvRp1.setVisibility(VISIBLE);
}
else if(order1.getToppingName2() == "null"){
TxtvCart1Topping2.setVisibility(GONE);
TxtvCart1ToppingPrice2.setVisibility(GONE);
TxtvRp2.setVisibility(GONE);
}
else if(order1.getToppingName2() != "null"){
//Topping 2
TxtvCart1Topping2.setVisibility(VISIBLE);

}

}
else if(order1.getToppingName4() == "null"){
TxtvCart1Topping4.setVisibility(GONE);
TxtvCart1ToppingPrice4.setVisibility(GONE);

}
else if(order1.getToppingName4() != "null"){
//Topping 4
TxtvCart1Topping4.setVisibility(VISIBLE);

TxtvRp4.setVisibility(VISIBLE);
}
else if(order1.getToppingName5() == "null"){
TxtvCart1Topping5.setVisibility(GONE);
TxtvCart1ToppingPrice5.setVisibility(GONE);
TxtvRp5.setVisibility(GONE);
}
else if(order1.getToppingName5() != "null"){
//Topping 5
TxtvCart1Topping5.setVisibility(VISIBLE);
TxtvCart1ToppingPrice5.setVisibility(VISIBLE);
TxtvRp5.setVisibility(VISIBLE);
}
else if(order1.getToppingName6() == "null"){
TxtvCart1Topping6.setVisibility(GONE);

}

}
else if(order1.getToppingName10() == "null"){
TxtvCart1Topping10.setVisibility(GONE);

TxtvRp10.setVisibility(VISIBLE);
}
else {
}
}

无论我做什么，未使用的浇头都不会GONE我已经尝试过将RemoveViewForUnusedTopping()功能放在按钮上，但按下它仍然不起作用。真的可以隐藏设置了SharedPreferences值的TextView吗？

Answer 1

在更改为Equal()后已经修复了它，并根据Textview分离if语句，并将其从"；空"；至"；none"；

private void RemoveViewForUnusedTopping() {
Order1 order1 = sharedPrefmanager.getInstance(getActivity()).GetOrder1();
//Make Unused View Topping Dissapear
//Topping 1
if (TxtvCart1Topping1.getText().equals("none")){
TxtvCart1Topping1.setVisibility(GONE);
TxtvCart1ToppingPrice1.setVisibility(GONE);
TxtvRp1.setVisibility(GONE);
}
else{
//Topping 1
TxtvCart1Topping1.setVisibility(VISIBLE);
TxtvCart1ToppingPrice1.setVisibility(VISIBLE);
TxtvRp1.setVisibility(VISIBLE);
}
if(TxtvCart1Topping2.getText().equals("none")){
TxtvCart1Topping2.setVisibility(GONE);
