如何在没有JsonArray名称的情况下获取Json对象 [英] How to get Json Object without JsonArray name

问题描述

我正在尝试解析从以下链接检索到的JSON数据

I am trying to parse the JSON data retrieved from the following link

http://fipeapi.appspot.com/api/1/carros /marcas.json

它没有JsonArray的名称.到目前为止，这是我尝试过的.

It does not have a name of the JsonArray. Here is what I have tried so far.

private String getName(int position) {
    String name = "";
    try {
        //Getting object of given index
        JSONObject json = result.getJSONObject(position);

        //Fetching name from that object
        name = json.getString(Config.TAG_NAME);
    } catch (JSONException e) {
        e.printStackTrace();
    }
    //Returning the name
    return name;
}

这是Config类

public class Config {
    //JSON URL
    public static final String DATA_URL = "http://fipeapi.appspot.com/api/1/carros/marcas.json";

    //Tags used in the JSON String
    public static final String TAG_USERNAME = "name";
    public static final String TAG_NAME = "fipe_name";
    public static final String TAG_COURSE = "key";
    public static final String TAG_ID_MARCA_CARRO = "id";

    //JSON array name
    public static final String JSON_ARRAY = "marcas";
}

如果您需要更多信息来帮助我解决此问题，请告诉我.预先感谢！

Please let me know if you need more information to help me in solving this problem. Thanks in advance!

推荐答案

在Android中解析JSON数据的更简单方法是使用

The easier way to parse a JSON data in Android is using Gson. It is simple and easier to integrate with your code. You just need to add the following dependency in your build.gradle file.

dependencies {
  implementation 'com.google.code.gson:gson:2.8.5'
}

现在，在代码中，您需要创建以下类.

Now in your code, you need to create the following class.

public class Car {
    public String name;
    public String fipe_name;
    public Integer order;
    public String key;
    public Long id;
}

现在只需解析您具有的JSON字符串，如下所示.

Now simply parse the JSON string you have like the following.

Gson gson = new Gson();
Car[] carList = gson.fromJson(jsonResponse, Cars[].class);

您会发现将JSON解析为对象数组.希望能有所帮助.

You will find the JSON parsed as an array of objects. Hope that helps.
