Question

我有一个动态的json响应，即使是键名和索引no.can也会改变

{
"Assigned": {
    "DC": 7,
    "EmpCode": "E0104",
    "FS": 8
}
}

我想将它转换为JsonArray并在对象下动态获取所有键名称和值＆＃39; Assigned＆＃39;。但我只是通过尝试获取值名称。

try {
                        //converting dynamic jsonobject to json array and fetching value as well as key name
                        JSONObject jsonObject = response.getJSONObject("Assigned");
                        Iterator x = jsonObject.keys();
                        JSONArray jsonArray = new JSONArray();
                        while (x.hasNext()) {
                            String key = (String) x.next();
                            jsonArray.put(jsonObject.get(key));
                    }
                        Toast.makeText(RolesActivity.this,jsonArray.toString(), Toast.LENGTH_LONG).show();
                        Log.d("jsonarray",jsonArray.toString());

                    }
                    catch (Exception e)
                    {
                        e.printStackTrace();
                        Toast.makeText(RolesActivity.this, e.toString(), Toast.LENGTH_SHORT).show();
                    }

Answer 1

您可以致电JSONObject.keys()（JSONObject）或JSONObject.names()（Iterator）<来获取JSONArray个键列表< / p>

之后，您可以遍历密钥，并使用JSONObject.getString(key)

获取每个密钥的值

Answer 2

首先创建一个pojo类

  private HashMap<String, String> parseResponse(){

    String json = ""; //  your json string

    Gson gson = new Gson();

    Response response =  gson.fromJson(json, Response.class)

    return response.getAssigned();

}


public class Response {

    @SerializedName("Assigned")
    private HashMap<String, String> assigned;

    public HashMap<String, String> getAssigned() {
        return assigned;
    }
}

比用Gson库解析。您可以从指定的Hashmap中读取键和值。

将json对象响应转换为数组并同时获取键和值android
