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);
}

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));
}
}
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();
}

Can anyone explain me how to do it. I am searching all over the topics but I still can't get it. Thanks.

listUsers.add(name);
} catch (JSONException e) {
e.printStackTrace();
}
}

adapter.notifyDataSetChanged();
}
}, new Response.ErrorListener() {
#Override

}
});
MyApplication.getInstance().addToReqQueue(jreq, "jreq");
}
}
try {
JSONObject jo = new JSONObject(response);
JSONArray jarray =jo.getJSONArray("listUsers");
for (int i = 0; i < jarray.length(); i++){
JSONObject jo2 = jarray.getJSONObject(i);
String name = jo2.getString("name");
listUsers.add(name);
}
} catch (JSONException e) {
e.printStackTrace();
}
Convert your String which is response to Json Object
JSONObject jsonObj = new JSONObject(response);
Then do the following
try {
if (jsonObj != null) {
if (jsonObj.optString("status").equals("ok")) {
JSONArray jsonArray = jsonObj.optJSONArray("listUsers");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.optJSONObject(i);
if (jsonObject != null) {
//Do work here
}
}
}
}
}catch (Exception e1) {
e1.printStackTrace();
}
try this and make changes accordingly and let me know if it work for you or not
JSONObject jo2 = jarray.getJSONObject(i);
You are iterating over the length of the response (a string). You should iterate over the length of jarray
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

} 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);

JSONArray _ArrayResponse=_JSONResponse.getJSONArray("result");
for(int i=0;i<_ArrayResponse.length();i++)

}
}
}
catch(JSONException e){Log.e(TAG,e.toString());}
try{

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")){

String profileNAme = jsonResult.getString("ProfileName");
String imageUrl = "", videoUrl = "";
//image url
if(jsonResult.has("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
I'm just trying to get a simple JSON array in the following format: ["Country1","Country2","Country3"] from the web and then use that array as a listview in my android app. I'm not stuck on how to make this JSON array, i'm just confused on how to get it into a listview in the app.
I have tried a few different tutorials, but none of them are using the same layout as such as mine.
My app is using a viewflipper, to keep a tabbased layout in view at all times throughout the app, therefore none of the tutorials seem to be working with my layout.
Any help is much appreciated.

Here's some code, yes i want to parse it from a web service and display it in a listview.

Update, here are the values of jArray as reported by Logcat:
08-26 16:49:07.246: VERBOSE/app(472): jarray value: ["Country1","Country2","Country3"]
These are the correct values!
This works in a simple test app I just created...
ListView list = (ListView) findViewById(...);
String json = "[\"Country1\",\"Country2\",\"Country3\"]";
try {
JSONArray array = (JSONArray) new JSONTokener(json).nextValue();
String[] stringarray = new String[array.length()];
for (int i = 0; i < array.length(); i++) {
stringarray[i] = array.getString(i);
}
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, stringarray);
list.setAdapter(adapter);
} catch (JSONException e) {
// handle JSON parsing exceptions...
}
