JSON数组得到JsonObject总是返回空

Question

我最近遇到了一个问题与org.json。我做了一个json数组与以下文本:

[{"name":"Stk.","unitNumber":1,"self":"https://link.com/units/1","products":"https://link.com/units/1/products"},{"name":"timer","unitNumber":2,"self":"https://link.com/units/2","products":"https://link.com/units/2/products"},{"name":"Stk.","unitNumber":3,"self":"https://link.com/units/3","products":"https://link.com/units/3/products"},{"name":"Kg","unitNumber":4,"self":"https://link.com/units/4","products":"https://link.com/units/4/products"},{"name":"Kg","unitNumber":5,"self":"https://link.com/units/5","products":"https://link.com/units/5/products"},{"name":"Km","unitNumber":6,"self":"https://link.com/units/6","products":"https://link.com/units/6/products"},{"name":"Liter","unitNumber":7,"self":"https://link.com/units/7","products":"https://link.com/units/7/products"},{"name":"Meter","unitNumber":8,"self":"https://link.com/units/8","products":"https://link.com/units/8/products"},{"name":"M2","unitNumber":9,"self":"https://link.com/units/9","products":"https://link.com/units/9/products"},{"name":"MM","unitNumber":10,"self":"https://link.com/units/10","products":"https://link.com/units/10/products"},{"name":"Meter","unitNumber":11,"self":"https://link.com/units/11","products":"https://link.com/units/11/products"},{"name":"Par","unitNumber":13,"self":"https://link.com/units/13","products":"https://link.com/units/13/products"},{"name":"Stk.","unitNumber":14,"self":"https://link.com/units/14","products":"https://link.com/units/14/products"},{"name":"Stk.","unitNumber":15,"self":"https://link.com/units/15","products":"https://link.com/units/15/products"},{"name":"Sæt","unitNumber":16,"self":"https://link.com/units/16","products":"https://link.com/units/16/products"},{"name":"Sæt","unitNumber":17,"self":"https://link.com/units/17","products":"https://link.com/units/17/products"},{"name":"u200e","unitNumber":19,"self":"https://link.com/units/19","products":"https://link.com/units/19/products"},{"name":"Stk.","unitNumber":20,"self":"https://link.com/units/20","products":"https://link.com/units/20/products"},{"name":"Stk.","unitNumber":21,"self":"https://link.com/units/21","products":"https://link.com/units/21/products"},{"name":"L","unitNumber":22,"self":"https://link.com/units/22","products":"https://link.com/units/22/products"}]

现在，我运行以下代码

for (int i = 0; i < jsonArray.length(); i++){
JSONObject jsonObject1 = new JSONObject(jsonArray.getJSONObject(i));
System.out.print("n"+jsonObject1.toString());
}

得到

{"empty"假}

每次。

我做错了什么?

你可以尝试下面的代码，并使用try catch for JSONException

for (int i = 0; i < jsonArray.length(); i++){
JSONObject jsonObject1 = jsonArray.getJSONObject(i);
System.out.print("n"+jsonObject1.toString());
}
