使用具有动态密钥的GSON解析JSON响应 [英] Parsing JSON response using GSON with dynamic Key

问题描述

这是我的JSON的样子，我必须解析JSON，如何使用GSON来完成

This is how my JSON looks like and I have to parse the JSON, how can this be done using GSON

{
  "data": {
    "a": {
      "abc": {
        "c": "d"
      }
    }
  }
}

其中"a"是动态键，可能会不时变化.我现在找不到解决方法

In which "a" is dynamic key which may vary from time to time. I am unable to find a solution right now

推荐答案

模型

public class Model {

    private HashMap<String, String> data;

    public Model() {
    }
}

使用Gson&将JSON字符串转换为Hashmap.从哈希图准备数据

Gson gson = new Gson();
Type typeHashMap = new TypeToken<Map<String, String>>(){}.getType();
Map<String,String> map = gson.fromJson(YOUR_JSON, typeHashMap);

Set<Map.Entry<String, String>> entrySet = data.entrySet();

    Iterator iterator = entrySet.iterator ();

    for(int j = 0; j < entrySet.size(); j++) {
        try {
            Map.Entry entry = (Map.Entry) iterator.next();
            String key = entry.getKey().toString();
            String value = entry.getValue().toString();
            //Add it to your list
        }
        catch(NoSuchElementException e) {
            e.printStackTrace();
        }
        break;
    }
