Я подаю заявку на ввод и вывод средств, так как я предоставил параметры API, и я могу получить ответ, но я хочу получить чистый результат для некоторых элементов в массиве: 

    {
    "user": {
        "id": "3",
        "first_name": "jef",
        "last_name": "handani",
        "email": "jeffryhandani@gmail.com",
        "verify_status": "1",
        "Store_name": "7 eleven",
        "Store_City": "Kuala Lumpur",
        "Store_Region": "Kuala Lumpur",
        "Store_address": "Jalan Bukit Jalil",
        "Latitudes": "5.9668083",
        "Longtitudes": "13.0338011",
        "created_by": null,
        "qr_code": "307",
        "first_login": "1"
    },
    "total_amount": "220.00",
    "total_fee": "20.00",
    "amount": "200",
    "method": "Express Exchange / Local bank transfer"
}

, поэтому мне нужно получить total_amount , total_fee , сумма и метод из ответа.

в следующем коде мне просто нужно получить данные, упомянутые выше, кто-нибудь может мне помочь с этим: 

private void depositVerify(){

    StringRequest request = new StringRequest(Request.Method.POST, URLstring, new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {

            TextView resp = findViewById(R.id.serverResp);

            resp.setText(response);


        }

    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {

        }
    }) {
        @Override
        protected Map<String, String> getParams() throws AuthFailureError {

            EditText amount = findViewById(R.id.editamount);

            Map<String, String> param = new HashMap<>();
            param.put("api_key", getApi_key());
            param.put("user_key", getUser_key());
            param.put("currency", "debit_base");
            param.put("amount", amount.getText().toString());
            param.put("method", "local_bank");

            return param;
        }
    };
    Volley.newRequestQueue(depositAlert1.this).add(request);

}

Шаг-1: интегрировать под библиотеку. 

implementation 'com.google.code.gson:gson:2.8.5'

Шаг-2: копировать ниже класса POJO. 

public class Example {

    @SerializedName("user")
    @Expose
    private User user;

    @Expose
    private String totalAmount;

    }

    public void setUser(User user) {
        this.user = user;
    }

    public String getTotalAmount() {
        return totalAmount;
    }

    public void setTotalAmount(String totalAmount) {
        this.totalAmount = totalAmount;
    }

    public String getTotalFee() {
        return totalFee;
    }

    public void setTotalFee(String totalFee) {
        this.totalFee = totalFee;
    }

    public String getAmount() {
        return amount;
    }

    public void setAmount(String amount) {
        this.amount = amount;
    }

    public String getMethod() {
        return method;

        }

        public String getVerifyStatus() {
            return verifyStatus;
        }

        public void setVerifyStatus(String verifyStatus) {
            this.verifyStatus = verifyStatus;

        }

        public void setStoreCity(String storeCity) {
            this.storeCity = storeCity;
        }

        public String getStoreRegion() {
            return storeRegion;
        }

        public void setStoreRegion(String storeRegion) {
            this.storeRegion = storeRegion;
        }

        public String getStoreAddress() {
            return storeAddress;
        }

        public void setStoreAddress(String storeAddress) {
            this.storeAddress = storeAddress;
        }

        public String getLatitudes() {
            return latitudes;
        }

        public void setLatitudes(String latitudes) {

        }

        public String getLongtitudes() {
            return longtitudes;

        public void setFirstLogin(String firstLogin) {
            this.firstLogin = firstLogin;
        }

    }
}

Шаг-3: Разбор ответа. 

private void depositVerify(){

        StringRequest request = new StringRequest(Request.Method.POST, URLstring, new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {

                Example example = new Gson().fromJson(response,Example.class);

                String total_amount = example.getTotalAmount();
                String total_fee = example.getTotalFee();
                String amount = example.getAmount();
                String method  = example.getMethod();

            }

        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {

            }
        }) {
            @Override
            protected Map<String, String> getParams() throws AuthFailureError {

                EditText amount = findViewById(R.id.editamount);

                Map<String, String> param = new HashMap<>();
                param.put("api_key", getApi_key());
                param.put("user_key", getUser_key());
                param.put("currency", "debit_base");
                param.put("amount", amount.getText().toString());
                param.put("method", "local_bank");

                return param;
            }
        };
        Volley.newRequestQueue(depositAlert1.this).add(request);

Вы должны попробовать этот код залпа, чтобы получить данные. 

private void depositVerify(){

    StringRequest stringRequest = new StringRequest(Request.Method.POST, URLstring, new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            try {
                JSONObject object = new JSONObject(response);
                String total_amount = object.getString("total_amount");
                String total_fee = object.getString("total_fee");
                String amount = object.getString("amount");
                String method = object.getString("method");

                // If you want to fetch "user" object data then you can fetch like this.
                JSONObject obj = object.getJSONObject("user");
                String id = obj.getString("id");
                String first_name = obj.getString("first_name");
                String last_name = obj.getString("last_name");
                String email = obj.getString("email");
                String verify_status = obj.getString("verify_status");
                String store_name = obj.getString("Store_name");
                String store_City = obj.getString("Store_City");
                String store_Region = obj.getString("Store_Region");
                String store_address = obj.getString("Store_address");
                String latitudes = obj.getString("Latitudes");
                String longtitudes = obj.getString("Longtitudes");
                String created_by = obj.getString("created_by");
                String qr_code = obj.getString("qr_code");
                String first_login = obj.getString("first_login");

                // Then either you can set in textview or edittext or you can add in bean class

                edt.setText(total_amount); //Like this you can set in edittext/textview

                MyBean bean = new MyBean();
                bean.setTotalAmount(total_amount); // Like this you can set in bean class  
                arrayList.add(bean); // Add bean in arraylist then set adapter.

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

    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {

        }
    }) {
        @Override
        protected Map<String, String> getParams() throws AuthFailureError {

            EditText amount = findViewById(R.id.editamount);

            Map<String, String> param = new HashMap<>();
            param.put("api_key", getApi_key());
            param.put("user_key", getUser_key());
            param.put("currency", "debit_base");
            param.put("amount", amount.getText().toString());
            param.put("method", "local_bank");

            return param;
        }
    };
    RequestQueue queue = Volley.newRequestQueue(depositAlert1.this);
    stringRequest.setRetryPolicy(new DefaultRetryPolicy(60000, DefaultRetryPolicy.DEFAULT_MAX_RETRIES, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
    queue.add(stringRequest);

Вы можете оценить JSON, как показано ниже. Попробуйте это. 

  try{

        JSONObject jsonObject = new JSONObject(reponse);
        String total_amount = jsonObject.getString("total_amount");
        String total_fee = jsonObject.getString("total_fee");
        String amount = jsonObject.getString("amount");
        String method = jsonObject.getString("method");

            DebugLog.e("total_amount " +  jsonObject.get("total_amount"));
            DebugLog.e("total_amount text " + jsonObject.getString("total_amount"));

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



output : E/MainActivity.java: [test:77]total_amount 220.00
        E/MainActivity.java: [test:78]total_amount text 220.00
...
