如何在没有JsonArray名称的情况下获取Json对象

本文介绍了如何在没有JsonArray名称的情况下获取Json对象的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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

fipeapi.appspot/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 = "fipeapi.appspot/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"; }

推荐答案

在Android中解析JSON数据的更简单方法是使用 Gson .与您的代码集成起来既简单又容易.您只需要在build.gradle文件中添加以下依赖项.

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.
