I'm trying to hide Text View that has value from SharedPreferences but it wont work at all.

here is part of my Code That get Value from SharedPreferences and set it to the text view

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();

                }
            }
        }
    }

and here is the function to hide Unused Topping that have default value "null" from SharedPreferences

private void RemoveViewForUnusedTopping() {
        Order1 order1 = sharedPrefmanager.getInstance(getActivity()).GetOrder1();
        //Make Unused View Topping Dissapear

    }

No matter what I do the Unused topping wont GONE I already try it to place the RemoveViewForUnusedTopping() function at button and pressed it still not working. Is it really possible to hide TextView that has SharedPreferences Value set to it ?

  • `order1.getToppingName1() == "null" ` - this check for String value container in the object is "null" or not. To check if `getToppingName1()` is null(empty) use `order1.getToppingName1() == null` , without the quotes on null or use `TextUtils.isEmpty(order1.getToppingName1())` – Nitish Nov 17 '21 at 09:55

  • I already try this and change the def value in `SharedPreferences` to `null` then change the if to `order1.getToppingName1() == null` still not working, I'll try to use the `TextUtils.isEmpty(order1.getToppingName1())` – Rafly Andrian Nov 17 '21 at 10:07
  • how about the `order1.getToppingName1() != null` with `TextUtils` ? – Rafly Andrian Nov 17 '21 at 10:11
  • I've change the `==` to `Equals()` to this `order1.getToppingName10().equals(null)` and `!order1.getToppingName10().equals(null)` still not working – Rafly Andrian Nov 17 '21 at 10:31

Already fixed it after change to the Equal() and separate the if statement per Textview and changed it from "null" to "none"

private void RemoveViewForUnusedTopping() {
        Order1 order1 = sharedPrefmanager.getInstance(getActivity()).GetOrder1();
        //Make Unused View Topping Dissapear

        if (TxtvCart1Topping1.getText().equals("none")){

        else{
            //Topping 1
