How Do I Modify My Function To Retrieve Json Objects To A Nested Json?

Here's the json I currently use in my code : {'forceDeviceLockout':0,'canStartValue':true,'destructOnRead':[30,60,300]} I use the following function to get the json values: privat

Solution 1:

I don't know why are you making it so complicated! but see this code I wrote for you. it might give you an idea:

public void printFieldsValues(Object object){
    try{
        Field[] fields = object.getClass().getFields();

        JSONObject jsonObject = new JSONObject();

        for(Field field : fields){
            jsonObject.put(field.getName(), field.get(object));
        }

        JSONObject newValue = new JSONObject("{\"canStartNewValue1\":true,"
                                             + "\"canStartroupValue\":true}");

        jsonObject.put("NEWVALUE", newValue);

        printJson(jsonObject);

    }catch(Exception e){
        e.printStackTrace();
    }
}

public void printJson(JSONObject jsonObject) throws JSONException{
    Iterator<String> keys = jsonObject.keys();
    String           key;
    while(keys.hasNext()){
        key = keys.next();
        try{
            printJson(new JSONObject(jsonObject.getString(key)));
        }catch(Exception e){
            Log.d("TAG", "key = " + key);
            Log.d("TAG", "value = " + jsonObject.get(key).toString());
        }
    }
}

and in your main Object you can call it like this:

printFieldsValues(this);

Solution 2:

If those json keys are predefined we can access them like this

   public class SampleModel {

        public int forceDeviceLockout;
        public boolean canStartValue;
        public int[] destructOnRead;
        public NestedModel NEWVALUE; 
}



  public class NestedModel {
    public boolean canStartNewValue1;
    public boolean canStartroupValue;
}



  Gson gson = new Gson();
  SampleModel sampleModel = gson.fromJson("{\"forceDeviceLockout\":0,\"canStartValue\":true,\"destructOnRead\":[30,60,300],\"NEWVALUE\":{\"canStartNewValue1\":true,\"canStartroupValue\":true}}",SampleModel.class);
  Log.d("canStartNewValue : " ,sampleModel.canStartNewValue)
  Log.d("canStartNewValue1 : " , sampleModel.NEWVALUE.canStartNewValue1);

Note : Need to add dependency compile 'com.google.code.gson:gson:2.8.2'

Solution 3:

If you just want to modify your current code to parse the json received you could just add if(value instance of JSONObject){ JSONObject jsonObject = (JSONObject) value; return jsonObject; }
