如何获取来自json数组的响应的大小

Question

我有一个 json 响应，其中存储了一些数据，现在我想获取 json 数组中存在的 json 对象的大小

[
    {
        "type": "Insurance Policies",
        "count": 2,
        "category_id": "1"
    },
    {
        "type": "Mediclaim Policies",
        "count": 1,
        "category_id": "2"
    },
    {
        "type": "Mutual Fund Policies",
        "count": 1,
        "category_id": "3"
    }
]

Answer 1

使用以下代码获取 JSON 数组长度

String jsonStringContent = [
    {
        "type": "Insurance Policies",
        "count": 2,
        "category_id": "1"
    },
    {
        "type": "Mediclaim Policies",
        "count": 1,
        "category_id": "2"
    },
    {
        "type": "Mutual Fund Policies",
        "count": 1,
        "category_id": "3"
    }
];

JSONArray jsonArray = new JSONArray(jsonStringContent);

int size = jsonArray.length();

Answer 2

好的，我得到了答案，我只需要创建 JSONArray 对象并将响应存储在该对象中，只需调用 object.length()
