将字符串转换为 JSON 数组 [英] Convert string to JSON array

问题描述

我有以下来自 Web 服务的 JSON 字符串，我正在尝试将其转换为 JSONarray

I have the following string of a JSON from a web service and am trying to convert this to a JSONarray

{
    "locations": [
        {
            "lat": "23.053",
            "long": "72.629",
            "location": "ABC",
            "address": "DEF",
            "city": "Ahmedabad",
            "state": "Gujrat",
            "phonenumber": "1234567"
        },
        {
            "lat": "23.053",
            "long": "72.629",
            "location": "ABC",
            "address": "DEF",
            "city": "Ahmedabad",
            "state": "Gujrat",
            "phonenumber": "1234567"
        },
        {
            "lat": "23.053",
            "long": "72.629",
            "location": "ABC",
            "address": "DEF",
            "city": "Ahmedabad",
            "state": "Gujrat",
            "phonenumber": "1234567"
        },
        {
            "lat": "23.053",
            "long": "72.629",
            "location": "ABC",
            "address": "DEF",
            "city": "Ahmedabad",
            "state": "Gujrat",
            "phonenumber": "1234567"
        },
        {
            "lat": "23.053",
            "long": "72.629",
            "location": "ABC",
            "address": "DEF",
            "city": "Ahmedabad",
            "state": "Gujrat",
            "phonenumber": "1234567"
        }
    ]
}

我在网上验证了这个 String，它似乎是正确的.现在我在android开发中使用以下代码来利用

I validated this String online, it seems to be correct. Now I am using the following code in android development to utilise

JSONArray jsonArray = new JSONArray(readlocationFeed);

这会引发异常类型不匹配异常.

This throws exception a type mismatch Exception.

推荐答案

这里你得到了 JSONObject 所以改变这一行:

Here you get JSONObject so change this line:

JSONArray jsonArray = new JSONArray(readlocationFeed); 

以下内容:

JSONObject jsnobject = new JSONObject(readlocationFeed);

之后

JSONArray jsonArray = jsnobject.getJSONArray("locations");
for (int i = 0; i < jsonArray.length(); i++) {
    JSONObject explrObject = jsonArray.getJSONObject(i);
}
