Question

keysArray（A，B，C）是dynamic和cores具有相同的对象名称？请帮忙!!!

{

 "result":"success",

 "keysArray":[
     "A",
     "B",
     "C",
     "D",
     "E"
     ],

 "cores":{

    "A":[{"key":"value"}],
    "B":[{"key":"value"}],
    "C":[{"key":"value"}],
    "D":[{"key":"value"}],
    "E":[{"key":"value"}]
 }
}

Answer 1

我已经以这种方式实现了它。

String responseStr = //JsonResponse here
Type type = new TypeToken<GetMainResponse>() {}.getType();
GetMainResponse getMainResponse = new GsonBuilder().excludeFieldsWithModifiers(Modifier.TRANSIENT).create().fromJson(responseStr, type);

    int size = getMainResponse.getKeysArray().size();
    for (int i = 0; i < size; i++) {
        JSONArray jCoreIngredients = new JSONObject(responseStr)
                                            .getJSONArray(getMainResponse.getKeysArray().get(i));
        String innerStr = jCoreIngredients.toString();
        Type type2 = new TypeToken<ArrayList<GetMainResponse.InnerCores>>() {}.getType();
        ArrayList<GetMainResponse.InnerCores> ingredientsInner = new GsonBuilder().excludeFieldsWithModifiers(Modifier.TRANSIENT).create().fromJson(innerStr, type2);
    }

//And this is my POJO

public class GetMainResponse{
String result;
ArrayList<String> keysArray;
Cores cores;

public String getResult() { return result; }

public void setResult(String result) { this.result = result; }

public ArrayList<String> getKeysArray() { return keysArray; }

public void setKeysArray(ArrayList<String> keysArray) { this.keysArray = keysArray; }

public Data getCores() { return data; }

public void setCores(Cores cores) { this.cores = cores; }

public class Cores {

// No declaration and not getter setter here.

 public class InnerCores {
    String key;

    public String getKey() { return key; }

    public void setKey(String result) { this.key = key; }

 }
}

任何建议：）

为此，我建议使用Go To JsonSchema2Pojo

去那里选择

来源类型：JSON
注释风格：GSON

然后单击底部的预览您将获得基于GSON的模型类

尝试使用它来获取我们的状态和描述。基于此代码，您可以创建自己的代码。这是主页的代码。

Gson gson = new Gson();
AboutUsRootObject joc = gson.fromJson(responseOutput.toString(), AboutUsRootObject.class);
resultStatus = joc.status;
resultOutputMsg = joc.message;

然后创建一个新类 AboutUsRootObject.java 并编写此代码：

 public class AboutUsRootObject {


        public int getStatus() {
            return status;
        }

        public void setStatus(int status) {
            this.status = status;
        }

        public String getMessage() {
            return message;
        }

        public void setMessage(String message) {
            this.message = message;
        }

        public AboutUsData getData() {
            return data;
        }

        public void setData(AboutUsData data) {
            this.data = data;
        }

        public int status ;
        public String message ;
        public AboutUsData data ;
    }

这里为数据定义了 getter setter 。数据键中包含更多数据，其核心键也是如此在你的中再次创建一个类似于上面的新类getter setter并继续。

试试这个：

try {
            JSONObject obj1 = new JSONObject(str);
            Gson gson = new Gson();
            Demo2 demo2 = gson.fromJson(obj1.toString(),Demo2.class);
            data3 = gson.toJson(demo2);
            Log.e("Main Activity",data3.toString());



        }catch (JSONException e) {

            e.printStackTrace();
        }

和Demo2类：

public class Demo2 {
    private String result;
    private ArrayList<String> keysArray;
    private Core cores;
    public String getResult() {
        return result;
    }

    public void setResult(String result) {
        this.result = result;
    }
    public ArrayList<String> getKeysArray() {
        return keysArray;
    }

    public void setKeysArray(ArrayList<String> keysArray) {
        this.keysArray = keysArray;
    }



    private class Core {
        private ArrayList<ClassD> D;
        private ArrayList<ClassE> E;
        private ArrayList<ClassC> C;
        private ArrayList<ClassB> B;
        private ArrayList<ClassA> A;

        public ArrayList<ClassA> getA() {
            return A;
        }

        public ArrayList<ClassB> getB() {
            return B;
        }

        public ArrayList<ClassC> getC() {
            return C;
        }

        public ArrayList<ClassD> getD() {
            return D;
        }

        public ArrayList<ClassE> getE() {
            return E;
        }

        private class ClassA {
            private String key;

            public String getKey() {
                return key;
            }

            public void setKey(String key) {
                this.key = key;
            }
        }

        private class ClassB {
            private String key;

            public String getKey() {
                return key;
            }

            public void setKey(String key) {
                this.key = key;
            }
        }

        private class ClassC {
            private String key;

            public String getKey() {
                return key;
            }

            public void setKey(String key) {
                this.key = key;
            }
        }

        private class ClassE {
            private String key;

            public String getKey() {
                return key;
            }

            public void setKey(String key) {
                this.key = key;
            }
        }

        private class ClassD {
            private String key;

            public String getKey() {
                return key;
            }

            public void setKey(String key) {
                this.key = key;
            }
        }


    }

    public Core getCores() {
        return cores;
    }

    public void setCores(Core cores) {
        this.cores = cores;
    }







}
