Show list of names from different objects in an array in JSON

I am trying to show the list of names (observation_name) from different objects in an array but I am just getting name from only the 1st index of the array its not iterating to the next name.

Here is the JSON:

{
"response_code": 1,
"status": "SUCCESS",
"message": "Record Found",
"result": {
    "observations": [
        {
            "id": 1,
            "observation_name": "Test Observation",
            "visit_id": 2,
            "created_at": "2022-03-12T07:55:57.000000Z",
            "updated_at": "2022-03-12T07:55:57.000000Z"
        },
        {
            "id": 2,
            "observation_name": "Test Observation 2",
            "visit_id": 2,
            "created_at": "2022-03-12T07:55:57.000000Z",
            "updated_at": "2022-03-12T07:55:57.000000Z"
        },
        {
            "id": 3,
            "observation_name": "Test Observation",
            "visit_id": 2,
            "created_at": "2022-03-12T07:56:18.000000Z",
            "updated_at": "2022-03-12T07:56:18.000000Z"
        },
        {
            "id": 4,
            "observation_name": "Test Observation 2",
            "visit_id": 2,
            "created_at": "2022-03-12T07:56:18.000000Z",
            "updated_at": "2022-03-12T07:56:18.000000Z"
        },
        {
            "id": 5,
            "observation_name": "Test Observation",
            "visit_id": 2,
            "created_at": "2022-03-13T09:56:09.000000Z",
            "updated_at": "2022-03-13T09:56:09.000000Z"
        },
        {
            "id": 6,
            "observation_name": "Test Observation 2",
            "visit_id": 2,
            "created_at": "2022-03-13T09:56:09.000000Z",
            "updated_at": "2022-03-13T09:56:09.000000Z"
        },
        {
            "id": 7,
            "observation_name": "Test Observation",
            "visit_id": 2,
            "created_at": "2022-03-13T09:56:58.000000Z",
            "updated_at": "2022-03-13T09:56:58.000000Z"
        },
        {
            "id": 8,
            "observation_name": "Test Observation 2",
            "visit_id": 2,
            "created_at": "2022-03-13T09:56:58.000000Z",
            "updated_at": "2022-03-13T09:56:58.000000Z"
        },
        {
            "id": 9,
            "observation_name": "Test Observation 3",
            "visit_id": 2,
            "created_at": "2022-03-13T09:56:58.000000Z",
            "updated_at": "2022-03-13T09:56:58.000000Z"
        }
    ]}}

This is how I am parsing the data:

        try {
        if (apiCalled == APICodes.GET_VISIT_DETAILS) {
            if (jsonResponse.getInt("response_code") == 1) {
                JSONObject result = jsonResponse.getJSONObject("result");
                JSONArray observations = result.getJSONArray("observations");
                PrescriptionModel model = new PrescriptionModel();
                for (int i = 0; i < observations.length(); i++) {
                    JSONObject observationItem = observations.getJSONObject(i);
                    Log.e("Observations:", observationItem.getString("observation_name"));
                    model.setObservation_name(observationItem.getString("observation_name"));
                    observationsList.add(model);
                    adapter.notifyDataSetChanged();
                }
            }
        }
    } catch (JSONException e) {
        e.printStackTrace();
    }

Looking for help, As I am kinda new to JSON parsing. Any help will be appreciated

>Solution :

It looks like you are always overwriting the name of PrecriptionModel. Instead, you probably want to create a new PrecriptionModel for each array entry. Also, I think the notifyDataSetChanged() is only needed after you added all new items to the list. So, try this please:

if (jsonResponse.getInt("response_code") == 1) {
    JSONObject result = jsonResponse.getJSONObject("result");
    JSONArray observations = result.getJSONArray("observations");

    for (int i = 0; i < observations.length(); i++) {
        PrescriptionModel model = new PrescriptionModel();
        JSONObject observationItem = observations.getJSONObject(i);
        Log.e("Observations:", observationItem.getString("observation_name"));
        model.setObservation_name(observationItem.getString("observation_name"));
        observationsList.add(model);
    }
    adapter.notifyDataSetChanged();
}
