I want to get two jsonArray from one url by using String Request

private void loadCricketPlayer() {
//getting the progressbar
final ProgressBar cricketProgressBar = findViewById(R.id.cricketProgressBar);
//making the progressbar visible
cricketProgressBar.setVisibility(View.VISIBLE);
StringRequest stringRequest = new StringRequest(Request.Method.GET, url_new,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
cricketProgressBar.setVisibility(View.INVISIBLE);
try {
//getting the whole json object from the response
JSONObject obj = new JSONObject(response);
JSONArray jArray = obj.getJSONArray("squad");
for (int i = 0; i < jArray.length(); i++) {
JSONObject jsonObject = jArray.getJSONObject(i);
JSONArray bArray = obj.getJSONArray("players");
for (int j = 0; j < bArray.length(); j++){
JSONObject jsonObject1 = bArray.getJSONObject(j);
cricket_Player_POJO cricketPlayer = new cricket_Player_POJO(jsonObject1.getString("name"));
cricketListItem.add(cricketPlayer);
}
}
cricket_Player_List cricketList = new cricket_Player_List(cricketListItem, getApplicationContext());
cricketPLayerlistView.setAdapter(cricketList);
} catch (JSONException e) {
e.printStackTrace();
}
}
},new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
//displaying the error in toast if occurrs
Toast.makeText(getApplicationContext(), error.getMessage(), Toast.LENGTH_SHORT).show();
}
});
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(stringRequest);
}
this is my json Array data for fetching the data from the server
This is my JSONARRAY example. For fetching the data:
{
"squad": [
{
"name": "Australia",
"players": [
{
"pid": 7252,
"name": "Tim Paine"
},
{
"pid": 489889,
"name": "Pat Cummins"
},
{
"pid": 5334,
"name": "Aaron Finch"
},
]
}]
}
How can I Fetch this code Help me How can I do it I am using volley for this and I want to fetch this data in the listview android

replace with this code
try {
//getting the whole json object from the response
JSONObject obj = new JSONObject(response);
JSONArray jArray = obj.getJSONArray("squad");
for (int i = 0; i < jArray.length(); i++) {
JSONObject jsonObject = jArray.getJSONObject(i);

for (int j = 0; j < bArray.length(); j++){
JSONObject jsonObject1 = bArray.getJSONObject(j);
cricket_Player_POJO cricketPlayer = new cricket_Player_POJO(jsonObject1.getString("name"));
cricketListItem.add(cricketPlayer);
}
}
cricket_Player_List cricketList = new cricket_Player_List(cricketListItem, getApplicationContext());
cricketPLayerlistView.setAdapter(cricketList);
} catch (JSONException e) {

Json Parser with volley library

I was searching a solution but I could not solve it.
thats my JSON
{"Error":"","Filme":[{
"title": "Dawn of the Planet of the Apes",
"image": "http://api.androidhive.info/json/movies/1.jpg",
"rating": 8.3,
"releaseYear": 2014,
"genre": ["Action", "Drama", "Sci-Fi"]
},
{
"title": "District 9",
"image": "http://api.androidhive.info/json/movies/2.jpg",
"rating": 8,
"releaseYear": 2009,
"genre": ["Action", "Sci-Fi", "Thriller"]
},
...
...
}]}
and that's my code
// Movies json url
private static final String url = "https://d....url....";
private ProgressDialog pDialog;
private List<Movie> movieList = new ArrayList<Movie>();
private HorizontalListView listView;
private CustomListAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView = (HorizontalListView) findViewById(R.id.list);
adapter = new CustomListAdapter(this, movieList);
listView.setAdapter(adapter);
pDialog = new ProgressDialog(this);
// Showing progress dialog before making http request
pDialog.setMessage("Loading...");
pDialog.show();
// changing action bar color
getActionBar().setBackgroundDrawable(
new ColorDrawable(Color.parseColor("#1b1b1b")));
// Creating volley request obj
JsonArrayRequest movieReq = new JsonArrayRequest(url ,new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
Log.d(TAG, response.toString());
hidePDialog();
// Parsing json
for (int i = 0; i < response.length(); i++) {
try {
JSONObject obj = response.getJSONObject(i).getJSONObject(TAG_MOVIE);
Movie movie = new Movie();
movie.setTitle(obj.getString("title"));
movie.setThumbnailUrl(obj.getString("image"));
movie.setRating(((Number) obj.get("rating"))
.doubleValue());
movie.setYear(obj.getInt("releaseYear"));
//Genre is json array
JSONArray genreArry = obj.getJSONArray("genre");
ArrayList<String> genre = new ArrayList<String>();
for (int j = 0; j < genreArry.length(); j++) {
genre.add((String) genreArry.get(j));
}
movie.setGenre(genre);
// adding movie to movies array
movieList.add(movie);
} catch (JSONException e) {
e.printStackTrace();
}
}
// notifying list adapter about data changes
// so that it renders the list view with updated data
adapter.notifyDataSetChanged();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
hidePDialog();
}
});
// Adding request to request queue
AppController.getInstance().addToRequestQueue(movieReq);
}
#Override
public void onDestroy() {
super.onDestroy();
hidePDialog();
}
private void hidePDialog() {
if (pDialog != null) {
pDialog.dismiss();
pDialog = null;
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
but the result is only a white layout. I think it is because my code don't find "Filme" variable in JSON but i don't know how to fix it.
any idea??
Thank you!!

"Filme" is not a JSONObject, it is a JSONArray actually. Simply parse it as a JSONArray :-)
EDIT:
First of all, use a StringRequest, not JSONArray, as the root of what you receive is NOT an JSONArray.
And then, once you have a simple String as a result, do something like this:
JSONObject root = new JSONObject(result);
JSONArray films = root.getJSONArray("Filme");
JSONObject obj;
for (int i = 0; i < films.length(); i++) {
obj = films.getJSONObject(i);
//Put all the parsing for a single Movie JSONObject here
}

Here is the solution that I made with “Kelevandos” help.
Maybe it can help someone.
// Request a string response from the provided URL.
StringRequest movieReq = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
//Log.d(TAG, response.toString());
hidePDialog();
JSONObject root;
try {
root = new JSONObject(response);
JSONArray films = root.getJSONArray("Filme");
JSONObject obj;
for (int i = 0; i < films.length(); i++) {
obj = films.getJSONObject(i);
//Put all the parsing for a single Movie JSONObject here
Movie movie = new Movie();
movie.setTitle(obj.getString("title"));
movie.setThumbnailUrl(obj.getString("image"));
movie.setRating(((Number) obj.get("rating"))
.doubleValue());
movie.setYear(obj.getInt("releaseYear"));
// Genre is json array
JSONArray genreArry = obj.getJSONArray("genre");
ArrayList<String> genre = new ArrayList<String>();
for (int j = 0; j < genreArry.length(); j++) {
genre.add((String) genreArry.get(j));
}
movie.setGenre(genre);
// adding movie to movies array
movieList.add(movie);

why I am having double brackets in json

why I am having double '[[' ?
should it be one bracket ? '['
[[{"name":"50 shade of
gray","path":"http://api.androidhive.info/json/movies/1.jpg","description":"long
story","likes":"5","comments":" Very
nice"},{"name":"Transformers","path":"http://api.androidhive.info/json/movies/2jpg","description":"Robots","likes":"7","comments":"
beautiful"},{"name":"Avangeers","path":"http://api.androidhive.info/json/movies/3.jpg","description":"hulk
and iron man","likes":"8","comments":" wow"}]]
this is my php
$sql = "select name , path , description , likes , comments from image ";
$res = mysqli_query($con,$sql);
$result = array();
while($row = mysqli_fetch_array($res)){
array_push($result,
array('name'=>$row[0],
'path'=>$row[1],
'description'=>$row[2],
'likes'=>$row[3],
'comments'=>$row[4]
));
}
echo json_encode(array($result));
mysqli_close($con);
And is it correct getting it in such code ?
JsonArrayRequest movieReq = new JsonArrayRequest(url,
new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
Log.d("r", response.toString());
hidePDialog();
System.out.print(response);
// Parsing json
for (int i = 0; i < response.length(); i++) {
try {
JSONObject obj = response.getJSONObject(i);
Movie movie = new Movie();
movie.setTitle(obj.getString("name"));
movie.setThumbnailUrl(obj.getString("path"));
movie.setRating(obj.getString("description"));
// movie.setRating(((Number) obj.get("description"))
// .doubleValue());
movie.setYear(obj.getString("likes"));
// movie.setYear(obj.getInt("likes"));
// Genre is json array
JSONArray genreArry = obj.getJSONArray("comments");
ArrayList<String> genre = new ArrayList<String>();
for (int j = 0; j < genreArry.length(); j++) {
genre.add((String) genreArry.get(j));
}
movie.setGenre(genre);
// adding movie to movies array
movieList.add(movie);
} catch (JSONException e) {
e.printStackTrace();
}
}
// notifying list adapter about data changes
// so that it renders the list view with updated data
adapter.notifyDataSetChanged();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
System.out.print(error);
VolleyLog.d(TAG, "Error: " + error.getMessage());
hidePDialog();
}
});

$result is an array.
You push associative arrays (that become objects) in that array, so now you have [{...},{...}]
Then you do:
echo json_encode(array($result));
so you get an array with an array in it, resulting in the above result with extra '[' around: [[{...},{...}]]

Parsing string to json on android

How to parse HTTP response ton JSON object ?
I changed my json code to:
{
"data": [{
"id": 1,
"sensor1": 76,
"sensor2": 75
}, {
"id": 2,
"sensor1": 76,
"sensor2": 206
}]
}
And my code is now:
JSONObject json = new JSONObject(mJson);
try {
data = json.getJSONArray("data");
for (int i = 0; i < json.length(); i++) {
HashMap<String, Integer> map = new HashMap<String, Integer>();
JSONObject obj = (JSONObject) data.get(i);
map.put(TAG_SENSOR_1, obj.getInt("sensor1"));
map.put(TAG_SENSOR_2, obj.getInt("sensor2"));
dataList.add(data.getInt("id") - 1, map);
}
} catch (JSONException e) {
e.printStackTrace();
}
But I have the same problem

edit your string to this format
{content:[{
first:1,
second:76,
third:75
},
{
first:2,
second:76,
third:75
},
{
first:3,
second:206,
third:75
},
{
first:4,
second:6,
third:175
},
{
first:5,
second:176,
third:75
}]
}
then use JSONObject and JSONArray to convert string
JSONArray array = new JSONObject(string).getJSONArray("content");
for(int i=0;i<array.size();i++){
JSONObject obj = array.get(i);
Log.i(TAG,"obj.getInt = "+obj.getInt("first"));
Log.i(TAG,"obj.getInt = "+obj.getInt("second"));
Log.i(TAG,"obj.getInt = "+obj.getInt("third"));
}

How to extract json data?

I am getting this trouble?
[
{
"username": "apap",
"status": "",
"log": "",
"email": "apap#gmail.com",
"lat": "",
"dob": "5-11-1986"
},
{
"username": "apapp",
"status": "",
"log": "",
"email": "apapp#gmail.com",
"lat": "",
"dob": "5-11-1986"
}
],
"returncode": "0"
}
Error parsing data org.json.JSONException: Value {"incircle": at response of type org.json.JSONObject cannot be converted to JSONArray
For extracting incircle array value,I am writing following code:
public class MainActivity extends Activity {
TextView username;
TextView email;
TextView dob;
TextView lat;
TextView log;
ListView listView;
ArrayList<HashMap<String,String>> jsonlist;
JsonAdapter objAdapter;
Context ctx;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
listView = (ListView) findViewById(R.id.listView);
jsonlist = new ArrayList<HashMap<String,String>>();
JSONObject json = JSONfunctions
.getJSONfromURL("http://www.railsboxtech.com/flirtalert/alluser.php");
try {
JSONArray flirt = json.getJSONArray("response");
Toast.makeText(MainActivity.this, "namr", Toast.LENGTH_LONG).show();
for (int i = 0; i < flirt.length(); i++) {
JSONObject ei = flirt.getJSONObject(i);
JSONArray eie = ei.getJSONArray("incircle");
for (int j = 0; j < eie.length(); j++) {
JSONObject e = eie.getJSONObject(j);
HashMap<String, String> map = new HashMap<String, String>();
map.put("User",e.getString("username"));
map.put("Email",e.getString("email"));
map.put("dob",e.getString("dob"));

}
ListAdapter adapter = new SimpleAdapter(this, jsonlist, R.layout.user_list,
new String[] { "User", "Email","dob","lat","log"}, new int[] {
R.id.username, R.id.email, R.id.dob, R.id.lat, R.id.log});
listView.setAdapter(adapter);
listView.setTextFilterEnabled(true);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}

When you retrieve the elements of the array with this line
JSONArray ja1= eie.getJSONArray(j);
You require the elements to be arrays themselfs, however, in your input the elements are objects.
Since the input has only one array but your code assumes two nested arrays, you probably want something like:
JSONObject json = JSONfunctions
.getJSONfromURL("http://www.railsboxtech.com/flirtalert/alluser.php");
try {
JSONObject ei = json.getJSONObject("response");
JSONArray eie = ei.getJSONArray("incircle");
for (int j = 0; j < eie.length(); j++) {
JSONObject e = eie.getJSONObject(j);
HashMap<String, String> map = new HashMap<String, String>();
map.put("User",e.getString("username"));
map.put("Email",e.getString("email"));
map.put("dob",e.getString("dob"));
map.put("lat",e.getString("lat"));
map.put("log",e.getString("log"));
jsonlist.add(map);
}
} catch ...
