This is code which I'm using:
#Override
protected String doInBackground(String... arg0) {
String yourJsonStringUrl = "GetCalender_Events";
JsonParser jParser = new JsonParser();
json = jParser.getJSONFromUrlArray(yourJsonStringUrl);
return null;
}
#Override
protected void onPostExecute(String strFromDoInBg) {
for (int i = 0; i < json.length(); i++) {
try {
JSONObject c = json.getJSONObject(i);
ldatosAgenda.add(new DatosAgenda(c.getString("Event_Name"), c.getString("Event_Name"),
sdf5.format(sdf1.parse(c.getString("Column1"))), sdf6.format(sdf1.parse(c.getString("Column1"))),
c.getString("Description")));
} catch (JSONException e) {
e.printStackTrace();
} catch (ParseException e) {
e.printStackTrace();
}
}
}
How to put my JSON Array into JSON object? Can anyone please help me, this is my first try with JSON Array.
My array looks like this:
{
"ContactList": [
{
"Column1": "22-05-2017",
"Event_Name": "Garba Compition",
"Description": "School organized garba compition"
},
{
"Column1": "24-05-2017",
"Event_Name": "Mahendi Compition",
"Description": "Mahendi compition"
}
]
}
#. Seems you are getting JSONObject as response. So you have to parse JSONObject first from sever response:
JSONObject json = jParser.getJSONFromUrlObject(yourJsonStringUrl);
#. Then parse ContactList and its item as below:
#Override
protected void onPostExecute(String strFromDoInBg) {
JSONArray jsonArray = json.getJSONArray("ContactList");
for (int i = 0; i < jsonArray.length(); i++) {
try
{
JSONObject c = jsonArray.getJSONObject(i);
ldatosAgenda.add(new DatosAgenda(c.getString("Event_Name"),c.getString("Event_Name"), sdf5.format(sdf1.parse(c.getString("Column1"))), sdf6.format(sdf1.parse(c.getString("Column1"))),c.getString("Description")));
} catch (JSONException e) {
e.printStackTrace();
} catch (ParseException e) {
e.printStackTrace();
}
}
}
JSONArray jsonarray = new JSONArray();
JSONObject jsonObject = new JSONObject();
try{
jsonObject.put(jsonarray);
} catch(JSONException e){
e.printStackTrace();
}
You get the values
JSONArray songobj = json.getJSONArray("ContactList");
Log.d(TAG, "List Length" + songobj.length());
for (int i = 0; i < songobj.length(); i++) {
JSONObject song = songobj.getJSONObject(i);
String column=song.getString("Column1");
String name=song.getString("Event_Name");
String desc=song.getString("Description");
ldatosAgenda.add(new DatosAgenda(column,name,desc));
}
}

First, I want to add all ArrayList Values into JsonObject then I want to add these JSON object to JsonArray I have done wright in the first I have added all ArrayList to JsonObject but I can't add all JsonObject to JsonArray.
This is my code to convert json object to json Array:-
submit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
JSONArray jsonArray = new JSONArray();
JSONObject jsonObject = new JSONObject();
for (int i = 0; i < records.size(); i++) {
try {
jsonObject.put("sid", records.get(i).getsid());
jsonObject.put("name", records.get(i).getpName());
jsonArray.put(jsonObject));
} catch (JSONException e) {
e.printStackTrace();
}
}
Log.e("ATTENDANCE", jsonArray.toString() + "");
}
});
I am getting only the last value of the ArrayList please help me I want The output to be like these
[
{
"student_no":"3924/08",
"firstname":"olana
},
{
"student_no":"4011/08",
"firstname":"yallem"
}
]
That is because you're creating only one object and putting it inside the for loop and you have to create new objects for every iteration.
Put your
JSONObject jsonObject = new JSONObject();
inside your for loop
like this
for (int i = 0; i < records.size(); i++) {
try {
JSONObject jsonObject = new JSONObject();
jsonObject.put("sid", records.get(i).getsid());
jsonObject.put("name", records.get(i).getpName());
jsonArray.put(jsonObject));
} catch (JSONException e) {
e.printStackTrace();
}
}
submit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
JSONArray jsonArray = new JSONArray();
for (int i = 0; i < records.size(); i++) {
try {
JSONObject jsonObject = new JSONObject();
jsonObject.put("sid", records.get(i).getsid());
jsonObject.put("name", records.get(i).getpName());
jsonArray.put(jsonObject));
} catch (JSONException e) {
e.printStackTrace();
}
}
Log.e("ATTENDANCE", jsonArray.toString() + "");
}
});
I'm getting the above-mentioned error while trying to extract data from JSONObject.My objective is to extract the "transactionId" data and store it in a variable for future use.
What I have so far:
protected void onPostExecute(String result) {
super.onPostExecute(result);
if (pd.isShowing()) {
pd.dismiss();
}
/*txtJson.setText(result);*/
JSONObject jsonarray;
try {
jsonarray = new JSONObject(result);
for (int i = 0; i < jsonarray.length(); i++) {
JSONObject mJsonObject = jsonarray.getJSONObject(i);
Log.d("OutPut", mJsonObject.getString("transactionId"));
}
} catch (JSONException e) {
e.printStackTrace();
}
}
My JSON Object is shown below:
{
"merchantId":"X",
"transactionId":"Y"
}
I'm new to Programming so any help would be appreciated.
Try this code
JSONArray jsonarray;
try {
jsonarray = new JSONArray(result);
for (int i = 0; i < jsonarray.length(); i++) {
JSONObject mJsonObject = jsonarray.optJSONObject(i);
Log.d("OutPut", mJsonObject.optString("transactionId"));
}
} catch (JSONException e) {
e.printStackTrace();
}
Also, if there is single ITEM in your JSONArray, you can remove forLoop.
And, if the response received is JSONObject then,
JSONObject jsonObject;
try {
jsonObject = new JSONObject(result);
Log.d("OutPut", jsonObject.optString("transactionId"));
} catch (JSONException e) {
e.printStackTrace();
}
Below is my Json response from getting when Hit on Url with parsing parameter strlogid=101
[
{
"earnpoints": 411,
"type": "C"
},
{
"earnpoints": 1600,
"type": "G"
},
{
"earnpoints": 13540,
"type": "I"
}
]
Below is my code-To show Points on 3 different textview
private class PointTask extends AsyncTask<String, Void, Boolean> {
protected Boolean doInBackground(final String... args) {
JSONParse jParser = new JSONParse();
HashMap<String, String> hMap = new HashMap<>();
hMap.put("strlogid", "101");
JSONArray jsonarray = jParser.getJSONFromUrl(url,hMap);
// get JSON data from URL
for (int i = 0; i < jsonarray.length(); i++) {
try {
JSONObject c = (JSONObject) jsonarray.get(i);
c_point=c.getString("points");
g_point=c.getString("points");
i_point=c.getString("points");
t_point = cpoint+gpoint+ipoint;
} catch (JSONException e) {
e.printStackTrace();
}
}
return null;
}
#Override
protected void onPostExecute(final Boolean success) {
txtTotalPoints.setText(t_point);
txtOwnPoints.setText(g_point);
txtClubPoints.setText(c_point);
txtVoucherPoints.setText(i_point);
}
}
TotalPoints,OwnPoints,ClubPoints,VoucherPoints are show on Textview respectively
Try this
protected Boolean doInBackground(final String... args) {
JSONParse jParser = new JSONParse();
HashMap<String, String> hMap = new HashMap<>();
hMap.put("strlogid", "101");
JSONArray jsonarray = jParser.getJSONFromUrl(url,hMap);
// get JSON data from URL
for (int i = 0; i < jsonarray.length(); i++) {
JSONObject c = (JSONObject) jsonarray.get(i);
if (c.getString("type").toString().equalsIgnoreCase("C")) {
c_point = c.getInt("earnpoints");
} else if (c.getString("type").toString().equalsIgnoreCase("G")) {
g_point = c.getInt("earnpoints");
} else if (c.getString("type").toString().equalsIgnoreCase("I")) {
i_point = c.getInt("earnpoints");
}
}
t_point = cpoint + gpoint + ipoint;
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(final Boolean success) {
txtTotalPoints.setText(t_point);
txtOwnPoints.setText(g_point);
txtClubPoints.setText(c_point);
txtVoucherPoints.setText(i_point);
}
}
Dont use async task for json parsing. I would reccomend you to use volley.
Here is the link\
http://www.androidhive.info/2014/05/android-working-with-volley-library-1/
#Override
public void onPostSuccess(String result, int id, boolean isSucess) {
// Log.e("re<><><><>", result);
try {
JSONArray ja = new JSONArray(result);
for (int arr = 0; arr < ja.length(); arr++) {
JSONObject json1 = ja.getJSONObject(arr);
Log.e("length", "" + ja.length());
// Getting JSON Array node
String earnpoints= json1.getString("earnpoints");
String type = json1.getString("type");
}
catch (JSONException e) {
e.printStackTrace();
Toast.makeText(LoginPage.this, "Please try again later", Toast.LENGTH_SHORT).show();

I am having the response of one of webservice to get the feeds list and in that response i am getting the two array with the same name.
The problem is that i am not able get the details of the inner array i.e. "ProfileName", "ImageUrl" etc..
I have tried the json parsing.
Below is the response of JSON:
{"Status":true,
"result":
[
{"result": [
{"ProfileName":"followers5","ImageUrl":"http:\/\/192.168.0.1\/webservice2\/uploads\/81.png","Likes":3,"Hearts":2},
{"ProfileName":"followers5","VideoUrl":"http:\/\/192.168.0.1\/webservice2\/uploads\/81.mp4","Likes":0,"Hearts":0}
]}
,{"result":[
{"ProfileName":"followers6","ImageUrl":"http:\/\/192.168.0.1\/webservice2\/uploads\/82.png","Likes":0,"Hearts":2},
{"ProfileName":"followers6","VideoUrl":"http:\/\/192.168.0.1\/webservice2\/uploads\/82.mp4","Likes":0,"Hearts":0}
]}
]
}
I have tried as below:
class feedtask extends AsyncTask<String, Integer, String> {
#Override
protected String doInBackground(String... params) {
Httputils getmethod = new Httputils();
try {
result = getmethod.Getrequest("feeds.php?uid=76");
System.out.println("Feeds Result--->" + result);
JSONObject jobj = new JSONObject(result);
JSONArray ja = jobj.getJSONArray("result");
for (int i = 0; i < ja.length(); i++) {
for (int j = 0; j <= i; j++) {
JSONObject jo = ja.getJSONObject(j);
abcd.add(jo.getString("ProfileName"));
System.out.println("Profile Name--->"
+ jo.getString("ProfileName"));
}
}
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return result;
}
}
Please help me out to get the details of the second array.
Any help will be appreciated.
Thank you.
try
{
JSONObject _JSONResponse=new JSONObject(response);
String status=_JSONResponse.getString("Status");
JSONArray _ArrayResponse=_JSONResponse.getJSONArray("result");
for(int i=0;i<_ArrayResponse.length();i++)
{
JSONArray object=_ArrayResponse.getJSONObject(i).getJSONArray("result");
for(int j=0;j<object.length();j++)
{
JSONObject jObject=object.getJSONObject(j);
ProfileName=jObject.getString("ProfileName") ;
VideoUrl=jObject.optString("VideoUrl") ;
Likes=jObject.optString("Likes") ;
Hearts=jObject.optString("Hearts") ;
Log.i(TAG,ProfileName +" "+VideoUrl +" "+Likes+" " +Hearts);
}
}
}
catch(JSONException e){Log.e(TAG,e.toString());}
try{
JSONObject responseJson = new JSONObject(response);
if(responseJson.has("result")){
JSONArray resultJsonArr = responseJson.getJSONArray("result");
for(int i=0; i<resultJsonArr.length(); i++){
JSONObject resultInstanceJson = resultJsonArr.getJSONObject(i);
if(resultInstanceJson.has("result")){
JSONArray resultArr = resultInstanceJson.getJSONArray("result");
for(int j=0; j<resultArr.length(); j++){
JSONObject jsonResult = resultArr.getJSONObject(j);
String profileNAme = jsonResult.getString("ProfileName");
String imageUrl = "", videoUrl = "";
//image url
if(jsonResult.has("ImageUrl")){
imageUrl = jsonResult.getString("ImageUrl");
}
//video url
if(jsonResult.has("VideoUrl")){
videoUrl = jsonResult.getString("VideoUrl");
}
}
}
}
}
}catch(Exception e){
e.printStackTrace();
}
try this way
for (int i = 0; i < ja.length(); i++) {
JSONObject jo = ja.getJSONObject(i);
JSONArray innerResult = jo.getJSONArray("result");
int size = innerResult.legth();
for (int j = 0; j < size; j++) {
JSONObject innerJo = innerResult.getJSONObject(j);
abcd.add(innerJo.getString("ProfileName"));
}
}
Edit:
public class InfoHolder {
public String profileName;
public String imageUrl;
public String videUrl;
}
for (int j = 0; j < size; j++) {
InfoHolder holder = new InfoHolder();
JSONObject innerJo = innerResult.getJSONObject(j);
// the same for imageUrl and videoUrl
holder.profileName = innerJo.getString("ProfileName");
abcd.add(holder);
}
of course you have to change from String to InfoHolder your abcd collectio
Try this:
try {
result = getmethod.Getrequest("feeds.php?uid=76");
System.out.println("Feeds Result--->" + result);
JSONObject jobj = new JSONObject(result);
JSONArray ja = jobj.getJSONArray("result");
for (int i = 0; i < ja.length(); i++) {
for (int j = 0; j < i; j++) {
JSONObject jo = ja.getJSONObject(j);
JSONArray resultJA = jo.getJSONArray("result");
for(int k=0;k< resultJA.length();k++){
JSONObject jo_inside = resultJA.getJSONObject(k);
String profileName = jo_inside.getString("ProfileName");
//use optString on JSONOBject. it will return empty String if that key does not exists or else the value u want. it won't give any exceptions.
String ImageURL = jo_inside.optString("ImageUrl");
String VideoURL = jo_inside.optString("VideoUrl");
}
}
}
}
catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return result;
}
}
You do
for (int i = 0; i < ja.length(); i++) {
ok for the first array now you need to get the array inside each cells of the first
For example :
JSONObject jo = ja.getJSONObject(i);
JSONArray ja2 = jo.getJSONArray("result");
then and only then you do the second loop
Maybe this answer isn't complete but the idea is here
{
"user": {
"name": ["bineesh", "Administrator", "binu", "binu", "bijith", "prem"]
},
"email": ["bineesh256#gmail.com", "erpadmin#gmail.com", "binu245#gmail.com", "binu245#gmail.com", "bijith256#gmail.com", "toast#gmail.com"],
"phone": ["7293553814", "12345", "0", "0", "0", "9046567239"]
}
I can't parse this response:
Object(result);
// JSONObject jObject;
// jObject= new JSONObject(result);
JSONArray ja = new JSONArray(result);
for (int i = 0; i < ja.length(); i++) {
JSONObject jo = (JSONObject) ja.get(i);
System.out.println(jo.getString("name"));
}
How can I see this response in listview?
Sample code:
public class HomeActivity extends ListActivity {
/** Called when the activity is first created. */
#SuppressWarnings({ "rawtypes", "unchecked" })
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter(this, android.R.layout.simple_list_item_1, this.fetchTwitterPublicTimeline()));
}
public ArrayList<String> fetchTwitterPublicTimeline()
{
ArrayList<String> listItems = new ArrayList<String>();
try {
URL twitter = new URL(
"http://twitter.com/statuses/public_timeline.json");
URLConnection tc = twitter.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(
tc.getInputStream()));
String line;
while ((line = in.readLine()) != null) {
JSONArray ja = new JSONArray(line);
for (int i = 0; i < ja.length(); i++) {
JSONObject jo = (JSONObject) ja.get(i);
listItems.add(jo.getString("text"));
}
}
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return listItems;
}
}
sample code :
public void parse(String s){
try {
JSONObject jsonObject = new JSONObject(s);
JSONObject namejObj = jsonObject.getJSONObject("user");
JSONArray nameArray = namejObj.getJSONArray("name");
for(int i =0;i<nameArray.length();i++){
Log.i("System out","name : "+nameArray.getString(i).toString());
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
You can use below method to parse JSON file
JSONObject obj = new JSONObject(result);
JSONObject objUser = obj.getJSONObject("user");
JSONArray arrUser = objUser.getJSONArray("name");
for(int i=0;i<arrUser.length();i++)
{
String name = arrUser.getString(i);
}
JSONArray arrEmail = objUser.getJSONArray("email");
for(int i=0;i<arrEmail.length();i++)
{
String email = arrEmail.getString(i);
}
JSONArray arrPhone = objUser.getJSONArray("phone");
for(int i=0;i<arrPhone.length();i++)
{
String phone = arrPhone.getString(i);
}
