I'm trying to display my row tables on the database in my ListView , However I dont know how to convert JSONObject to JSONArray and set it to my setter class. I get my JSON through Volley String Request
I have the JSON output like this :
{
"error": false,
"message": "Status Fetched",
"status": [
{
"OrderCode": "5x2azu",
"GuestName": "Try",
"ProductName": "Mie Ayam Super Jumbo Komplit",
"ProductType": "Kuah",
"NoTable": 4,
"Status": "Disiapkan",
"TotalPrice": "58000"
},
{
"OrderCode": "etent3",
"GuestName": "Try",
"ProductName": "Nasi Soto Daging Sapi",
"ProductType": "Soto",
"NoTable": 4,
"Status": "Disiapkan",
"TotalPrice": "27000"
},
{
"OrderCode": "ro1eyx",
"GuestName": "Try",
"ProductName": "Mie Ayam Original",
"ProductType": "Kuah",
"NoTable": 4,
"Status": "Disiapkan",
"TotalPrice": "23000"
}
]
}
and here is my String Request :
public void StringRequest() {
StringRequest stringRequest = new StringRequest(Request.Method.POST, URLs.STATUS,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
try {
JSONObject obj = new JSONObject(response);
Toast.makeText(getContext(), response, Toast.LENGTH_SHORT).show();
//if no error in response
if (!obj.getBoolean("error")) {
Toast.makeText(getContext(), obj.getString("message"), Toast.LENGTH_SHORT).show();
//getting Status from response
JSONObject statusJson = obj.getJSONObject("status");
Status status = new Status(
statusJson.getString("OrderCode"),
statusJson.getString("GuestName"),
statusJson.getString("ProductName"),
statusJson.getString("ProductType"),
statusJson.getString("NoTable"),
statusJson.getString("Status"),
statusJson.getString("TotalPrice")
);
} else {
Toast.makeText(getContext(), obj.getString("message"), Toast.LENGTH_SHORT).show();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
@Override
public void one rrorResponse(VolleyError error) {
Toast.makeText(getContext(),error.getMessage(),Toast.LENGTH_SHORT).show();
}
}) {
@Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String,String> params = new HashMap<>();
params.put("tablecode",TableCode);
return params;
}
};
VolleySingleton.getInstance(getContext()).addToRequestQueue(stringRequest);
}
I dont know how to convert it from JSONObject to JSONArray
here is my Setter and getter class
package com.example.pesanpalgading20.Getter.Status;
import java.util.ArrayList;
public class Status {
private String OrderCode,Name,FoodName,TypeFood,NoTable,Status,TotalPrice;
public Status(){
}
public Status(String orderCode, String name, String foodName, String typeFood, String noTable, String status, String totalPrice) {
OrderCode = orderCode;
Name = name;
FoodName = foodName;
TypeFood = typeFood;
NoTable = noTable;
Status = status;
TotalPrice = totalPrice;
}
public String getOrderCode() {
return OrderCode;
}
public void setOrderCode(String orderCode) {
OrderCode = orderCode;
}
public String getName() {
return Name;
}
public void setName(String name) {
Name = name;
}
public String getFoodName() {
return FoodName;
}
public void setFoodName(String foodName) {
FoodName = foodName;
}
public String getTypeFood() {
return TypeFood;
}
public void setTypeFood(String typeFood) {
TypeFood = typeFood;
}
public String getNoTable() {
return NoTable;
}
public void setNoTable(String noTable) {
NoTable = noTable;
}
public String getStatus() {
return Status;
}
public void setStatus(String status) {
Status = status;
}
public String getTotalPrice() {
return TotalPrice;
}
public void setTotalPrice(String totalPrice) {
TotalPrice = totalPrice;
}
}
so how do I set the value of the each JSON to SetterandGetter class ?
CodePudding user response：
try {
JSONObject obj = new JSONObject(response);
//if no error in response
if (!obj.getBoolean("error")) {
//getting Status from response
JSONArray statusJson = obj.getJSONArray("status");
for (int i = 0; i < statusJson.length(); i ) {
Status status = new Status(
statusJson.getJSONObject(i).getString("OrderCode"),
statusJson.getJSONObject(i).getString("GuestName"),
statusJson.getJSONObject(i).getString("ProductName"),
statusJson.getJSONObject(i).getString("ProductType"),
statusJson.getJSONObject(i).getString("NoTable"),
statusJson.getJSONObject(i).getString("Status"),
statusJson.getJSONObject(i).getString("TotalPrice")
);
// Add Status In your Array list and enjoy
}
} else {
Toast.makeText(getContext(), obj.getString("message"), Toast.LENGTH_SHORT).show();
}
} catch (JSONException e) {
e.printStackTrace();
}
CodePudding user response：
You can use Gson library and convert your json to a model class
To do it first you have to add gson as a dependancy
implementation "com.google.code.gson:gson:2.8.6"
And then since your status in json is array use it like this
JSONArray status = obj.getJSONArray("status");
//Code to convert json array to arraylist of object
Arraylist<Status> arraylist = Gson().fromJson(
status.toString(),
new TypeToken<ArrayList<Status>>(){}.getType()
)
Above code will store your json array status to arraylist variable
CodePudding user response：
so the gettin JSON array is completed but it still display one list from the array this is the code
public void StringRequest() {
StringRequest stringRequest = new StringRequest(Request.Method.POST, URLs.STATUS,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
try {
JSONObject obj = new JSONObject(response);
Toast.makeText(getContext(), response, Toast.LENGTH_SHORT).show();
//if no error in response
if (!obj.getBoolean("error")) {
Toast.makeText(getContext(), obj.getString("message"), Toast.LENGTH_SHORT).show();
//getting Status from response
JSONArray statusJson = obj.getJSONArray("status");
for (int i = 0; i < statusJson.length(); i ) {
Status status = new Status(
statusJson.getJSONObject(i).getString("OrderCode"),
statusJson.getJSONObject(i).getString("GuestName"),
statusJson.getJSONObject(i).getString("ProductName"),
statusJson.getJSONObject(i).getString("ProductType"),
statusJson.getJSONObject(i).getString("NoTable"),
statusJson.getJSONObject(i).getString("Status"),
statusJson.getJSONObject(i).getString("TotalPrice")
);
ArrayList<Status> statusList = new ArrayList<Status>();
statusList.add(status);
statusAdapter = new StatusAdapter(getActivity(),statusList);
StatusListView.setAdapter(statusAdapter);
}
} else {
Toast.makeText(getContext(), obj.getString("message"), Toast.LENGTH_SHORT).show();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
@Override
public void one rrorResponse(VolleyError error) {
Toast.makeText(getContext(),error.getMessage(),Toast.LENGTH_SHORT).show();
}
}) {
@Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String,String> params = new HashMap<>();
params.put("tablecode",TableCode);
return params;
}
};
VolleySingleton.getInstance(getContext()).addToRequestQueue(stringRequest);
}
I dont know where to put the increment in the setting adapter in
statusList.add(status);
edit : It solved! Thanks to @Pratik Fagadiya I put the setting adapter outside of the loop and it worked and added more than 1 list
