Google offers a very good json parser GSON.
Take a look here

Gson is a superb library for this. First generate the POJO for the json you have from jsonschematopojo. Here is the following POJO class:
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
import java.util.List;
public class JsonResponse {
#SerializedName("data")
#Expose
private List<Datum> data = null;
public List<Datum> getData() {
return data;
}
public void setData(List<Datum> data) {
this.data = data;
}
public class Datum {
#SerializedName("widget")
#Expose
private Widget widget;
public Widget getWidget() {
return widget;
}
public void setWidget(Widget widget) {
this.widget = widget;
}
}
public class Image {
#SerializedName("src")
#Expose
private String src;
#SerializedName("name")
#Expose
private String name;
#SerializedName("hOffset")
#Expose
private int hOffset;
#SerializedName("vOffset")
#Expose
private int vOffset;
#SerializedName("alignment")
#Expose
private String alignment;
public String getSrc() {
return src;
}
public void setSrc(String src) {
this.src = src;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getHOffset() {
return hOffset;
}
public void setHOffset(int hOffset) {
this.hOffset = hOffset;
}
public int getVOffset() {
return vOffset;
}
public void setVOffset(int vOffset) {
this.vOffset = vOffset;
}
public String getAlignment() {
return alignment;
}
public void setAlignment(String alignment) {
this.alignment = alignment;
}
}
public class Text {
#SerializedName("data")
#Expose
private String data;
#SerializedName("size")
#Expose
private int size;
#SerializedName("style")
#Expose
private String style;
#SerializedName("name")
#Expose
private String name;
#SerializedName("hOffset")
#Expose
private int hOffset;
#SerializedName("vOffset")
#Expose
private int vOffset;
#SerializedName("alignment")
#Expose
private String alignment;
#SerializedName("onMouseUp")
#Expose
private String onMouseUp;
public String getData() {
return data;
}
public void setData(String data) {
this.data = data;
}
public int getSize() {
return size;
}
public void setSize(int size) {
this.size = size;
}
public String getStyle() {
return style;
}
public void setStyle(String style) {
this.style = style;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getHOffset() {
return hOffset;
}
public void setHOffset(int hOffset) {
this.hOffset = hOffset;
}
public int getVOffset() {
return vOffset;
}
public void setVOffset(int vOffset) {
this.vOffset = vOffset;
}
public String getAlignment() {
return alignment;
}
public void setAlignment(String alignment) {
this.alignment = alignment;
}
public String getOnMouseUp() {
return onMouseUp;
}
public void setOnMouseUp(String onMouseUp) {
this.onMouseUp = onMouseUp;
}
}
public class Widget {
#SerializedName("debug")
#Expose
private String debug;
#SerializedName("window")
#Expose
private Window window;
#SerializedName("image")
#Expose
private Image image;
#SerializedName("text")
#Expose
private Text text;
public String getDebug() {
return debug;
}
public void setDebug(String debug) {
this.debug = debug;
}
public Window getWindow() {
return window;
}
public void setWindow(Window window) {
this.window = window;
}
public Image getImage() {
return image;
}
public void setImage(Image image) {
this.image = image;
}
public Text getText() {
return text;
}
public void setText(Text text) {
this.text = text;
}
}
public class Window {
#SerializedName("title")
#Expose
private String title;
#SerializedName("name")
#Expose
private String name;
#SerializedName("width")
#Expose
private int width;
#SerializedName("height")
#Expose
private int height;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getWidth() {
return width;
}
public void setWidth(int width) {
this.width = width;
}
public int getHeight() {
return height;
}
public void setHeight(int height) {
this.height = height;
}
}
}
Now copy the entire json data and paste it in a String variable:
String jsonData="{\n" +
"\n" +
"\"data\":[ {\"widget\": { \"debug\": \"on\", \"window\": { \"title\": \"Sample Konfabulator Widget\", \"name\": \"main_window\", \"width\": 500, \"height\": 500 }, \"image\": { \"src\": \"Images/Sun.png\", \"name\": \"sun1\", \"hOffset\": 250, \"vOffset\": 250, \"alignment\": \"center\" }, \"text\": { \"data\": \"Click Here\", \"size\": 36, \"style\": \"bold\", \"name\": \"text1\", \"hOffset\": 250, \"vOffset\": 100, \"alignment\": \"center\", \"onMouseUp\": \"sun1.opacity = (sun1.opacity / 100) * 90;\" } }}\n" +
"\n" +
"]}"
Gson gson = new Gson();
JsonResponse jsonresp= gson.fromJson(jsonData, JsonResponse.class);
Now if you want to read from a file, then apply these codes:
public String mockDataReader(String fileName) {
try {
Path path = Paths.get(getClass().getClassLoader()
.getResource(fileName).toURI());
StringBuilder data = new StringBuilder();
Stream<String> lines = Files.lines(path);
lines.forEach((String line) -> data.append(line).append("\n"));
lines.close();
path = null;
return data.toString();
} catch (URISyntaxException e) {
e.printStackTrace();
return null;
} catch (IOException e) {
e.printStackTrace();
return null;
} catch (Exception e) {
e.printStackTrace();
return null;
}
}

Retrofit with Gson Response.body() not working

I'am trying to parse data to a recyclerview, i had some problems about expecting JSONArray/JSONObject that i fixed with some help, but this moment I am a little bit lost in what to do in the Onresponse, the original - generatePhonesList(response.body()) isnt working.
this is my json and i am trying to parse the data inside the array results[] :
{
"success": true,
"metadata": {
"sort": "POPULARITY",
"total_products": 20,
"title": "Phones & Tablets",
"results": [

"image": "https://cdn2.gsmarena.com/vv/bigpic/samsung-galaxy-s9-.jpg",

},
MainActivity (CALL and Recyclerview creation) :
GetPhoneDataService service = RetrofitInstance.getRetrofitInstance().create(GetPhoneDataService.class);
Call<APIReponse> call = service.getAllPhones();
call.enqueue(new Callback<APIReponse>() {
#Override
public void onResponse(Call<APIReponse> call, Response<APIReponse> response) {
generatePhonesList(response.body());
}
#Override
public void onFailure(Call<APIReponse> call, Throwable t) {
Log.e("eee" , "" + t.getMessage());
}
});
}
private void generatePhonesList(List<Result> phonesList){
recyclerView = findViewById(R.id.recyclerView);
adapter = new PhonesAdapter(phonesList,this);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(MainActivity.this);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setAdapter(adapter);
}
this is the POJO Class's created in jsonschema2pojo :

You are passing the APIReponse model to the generatePhonesList(List<Result> phonesList) function. You need to pass only the list of results in this function.
Replace this:
generatePhonesList(response.body());
with:
generatePhonesList(response.body().getMetadata().getResults());
Here getMetadata() and getResults() are the getter functions of metadata model and List.

If you pay close attention response.body() will provide you with class APIResponse. But you need is List<Result>. To achieve this, try response.body().getMetadata().getResults()
This should give you the desired output.

this is how i call it

getPhoto.enqueue(new Callback<List<UserDataResponse>>() {
#Override
public void onResponse(Call<List<UserDataResponse>> call, Response<List<UserDataResponse>>response) {
// String iserror = response.body().getIserror();
// Jika login berhasil maka data nama yang ada di response API
// akan diparsing ke activity selanjutnya.
List<UserDataResponse> userDatalist = response.body();
//Creating an String array for the ListView
String[] iserror = new String[userDatalist.size()];
//looping through all the heroes and inserting the names inside the string array
for (int i = 0; i < userDatalist.size(); i++) {
iserror[i] = userDatalist.get(i).getIserror();
if (iserror.equals("false")) {
String[] url = new String[userDatalist.size()];
url[i] = userDatalist.get(i).getImages().getimage_Url();
showPhoto(url);
}
}
#Override
public void onFailure(Call<List<UserDataResponse>> call, Throwable t){
Log.e("debug", "onFailure: ERROR > " + t.toString());
}
});
}
and my question is how i can call response "url" from array i tried to call method getimage_Url() after method getImage() but i cannot call it
url[i] = userDatalist.get(i).getImages().getimage_Url();

According your above json, it's return Object rather than Array. So, modify your F0_getPhoto to handle this.
public void F0_getPhoto(){
Call<UserDataResponse> getPhoto = mApiService.getImage(
String.valueOf(mPrefs.getUserID()));
getPhoto.enqueue(new Callback<UserDataResponse>() {
#Override
public void onResponse(Call<UserDataResponse> call, Response<UserDataResponse>response) {
// String iserror = response.body().getIserror();
// Jika login berhasil maka data nama yang ada di response API
// akan diparsing ke activity selanjutnya.
UserDataResponse userData = response.body();
//Creating an String array for the ListView
String error = userData.getIserror();
List<Image> images = userData.getImages();
String[] url = new String[images.size()];
//looping through all the heroes and inserting the names inside the string array
if (iserror.equals("false")) {
for (int i = 0; i < images.size(); i++) {
url[i] = images.getimage_Url();
}
showPhoto(url);
}
#Override
public void onFailure(Call<UserDataResponse> call, Throwable t){
Log.e("debug", "onFailure: ERROR > " + t.toString());
}
});
}
}

Using GSON to parse an JSON object with an array of elements

How can I use GSON to parse the following JSON object:

The code that I use is the following:

String mMessage = response.body().string();
if (response.isSuccessful())
{
try
{
Gson gson = new Gson();
final ProductItems categoryProducts = gson.fromJson(mMessage, ProductItems.class);
response.close();
}
catch (Exception e)
{
Log.e("Error", "Failed to upload");
e.printStackTrace();
}
However, I get the following error: GSON throwing “Expected BEGIN_OBJECT but was BEGIN_ARRAY.
I have tried to change the ProductItems class to taking an object for productbycategories but then I get the following error: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected a string but was BEGIN_OBJECT at line 1 column 2324 path $.ProductsByCategory[0].meta_data[0].value. I am now a bit confused.

The reason you get this error is that the data is not consistent with the way the POJO is generated.
This is the specific part of the data that has the issue:
"meta_data": [
{
"id": 14232,
"key": "_vc_post_settings",
"value": {
"vc_grid_id": []
}
},
{
"id": 14273,
"key": "fb_product_description",
"value": ""
},
{
"id": 14274,
"key": "fb_visibility",
"value": "1"
},
Notice how the "meta_data" field is an array of objects and that these objects contain a "value" field. The data type of the "value" varies- sometimes it's an object and other times it's a string.
One possible solution would be to change the MetaDatum class so that the value is an Object:
package com.example;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class MetaDatum {
...
#SerializedName("value")
#Expose
private Object value;
...
public Object getValue() {
return value;
}
public void setValue(Object value) {
this.value = value;
}
}

How can I set My Json Value in Adapter

My Problem is that how can send the data in model.
My Model Should contain data Like id,displayName,amountMin,eta,image,amountMax

First of all you need to make two different models for category and ride_estimate.Because they both are in different loops. Also try this
for (j = 0; j < ride_estimate.length(); j++) {
Log.e("sushil", String.valueOf(j));
rideestimate = ride_estimate.getJSONObject(j);
distance = rideestimate.getString("distance");
amount_min = rideestimate.getString("amount_min");
amount_max = rideestimate.getString("amount_max");
category = rideestimate.getString("category");
OlaUberModel olaUberModel = new OlaUberModel(category, display_name, amount_min, eta, image, amount_max);
arrayList.add(olaUberModel);
}
May be this would helpful for you..
Thanks!

replace
eta = jsonObject.getString("eta");
by
int eta = jsonObject.getInt("eta");

On the basis of id of any cab type "prime" you can fetch image. what say

create some class as per your data

Now compile a library compile 'com.google.code.gson:gson:2.8.2'
then write few line to get your data fill in class
Gson gson = new Gson();
Example example = gson.fromJson(mainObj, Example.class);

How to parse all json objects and send them inside a class?

This is the response JSON from Volley:
{
"status":true,
"data":{
"product_id":"12",
"product_ogpm_id":"OGPR1000485",
"product_part_number":"6ED1 057-1AA01-0BA0",
"escape_part_number":"6ed10571aa010ba0",
"product_name":"USB PC Cable",
"product_uom":"",
"product_image":"",
"product_description":"",
"product_manufacturer":"Siemens",
"manufacturer_id":"4",
"replace_id":"0",
"replace_date":"0000-00-00 00:00:00",
"product_added_date":"2017-09-12 00:57:15",
"product_added_by":"Jayank Chopra",
"product_modified_date":"0000-00-00 00:00:00",
"product_modified_by":"",
"product_status":"1",
"manufacturer_name":"Siemens",
"contracted_id":"1",
"data_sheets":[
]
},
"message":"Product found!"
}
For Parsing I use Gson Like this:
/* BarcodeSearchResponse responseObj = new Gson().fromJson(responseJson.toString(), BarcodeSearchResponse.class);
where BarcodeSearchResponse class is this:
public class BarcodeSearchResponse{
public ArrayList<ScanData> data;
}
*/
And ScanData is a class that contains :
public class ScanData implements Parcelable{

#SerializedName("product_ogpm_id")

private String productOgpmId;
#SerializedName("product_part_number")

or if it same with you posted
Please make sure the BarcodeSearchResponse look like this:

And your ScanData Class should use this Data Class as following.
public class ScanData {
#SerializedName("status")
#Expose
private Boolean status;
#SerializedName("data")
#Expose
private Data data;
#SerializedName("message")
#Expose
private String message;
public Boolean getStatus() {

}
public void setStatus(Boolean status) {
this.status = status;
}
public Data getData() {
return data;
}
public void setData(Data data) {
this.data = data;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
P.S.
I have not made it parcelable, I guess you can do that by yourself.
