The above sample json array , how to get the 204, 203 and 202? Thanks
I tried:
JSONArray issueArray = new JSONArray(jsonContent);
for (int j = 0; j < issueArray.length(); j++) {
JSONObject issue = issueArray.getJSONObject(j);
String _pubKey = issue.getString(0);
}
above sample json array , how to get the 204, 203 and 202?
No, current String is JSONObject instead of JSONArray. you should get Iterator using JSONObject. keys () if inner JSONObject keys dynamic as:
JSONObject issueObj = new JSONObject(jsonContent);
Iterator iterator = issueObj.keys();
while(iterator.hasNext()){
String key = (String)iterator.next();
JSONObject issue = issueObj.getJSONObject(key);
// get id from issue
String _pubKey = issue.optString("id");
}
Answer given by Mr. K is also right but you can also use jsonObject names() method. please find the sample code
for(int i = 0; i<jsonobject.length(); i++){
Log.e(TAG, "Key = " + jsonobject.names().getString(i) + " value = " + jsonobject.get(jsonobject.names().getString(i)));
}
I hope dis will help you
User this method to iterate json dynamically
private void parseJson(JSONObject data) {
if (data != null) {
Iterator<String> it = data.keys();
while (it.hasNext()) {
String key = it.next();
try {
if (data.get(key) instanceof JSONArray) {
JSONArray arry = data.getJSONArray(key);
int size = arry.length();
for (int i = 0; i < size; i++) {
parseJson(arry.getJSONObject(i));
}
} else if (data.get(key) instanceof JSONObject) {
parseJson(data.getJSONObject(key));
} else {
System.out.println("" + key + " : " + data.optString(key));
}
} catch (Throwable e) {
System.out.println("" + key + " : " + data.optString(key));
e.printStackTrace();
}
}
}
}
You can also use names() as below to get the keys as JSONArray :
JSONArray jArray = jsonObject.names();
int len = jsonObject.length();
for (int i=0; i<len; i++) {
String keyName = (String)jArray.get(i);
JSONObject jValue = jsonObject.getJSONObject(keyName);
String _pubKey = jValue.optString("id");
//get the other values from jValue
}
Here you are trying to get JSONArray but in json response it is JSONObject.
Use following code.
JSONObject issueObject = new JSONObject(jsonContent);
String _pubKey = issueObject.getString(0);

This is nested array function here in loop I'm getting array index{0,1,2,0,1,2,0} like this i have all editetxt prices list by using im not able to update index position values mismatching

I just changed for loop condition and changed format of getting json values now its working fine
I am trying to fetch data from MySQL database and trying to show it into a table. For this I am using volley.
JSONArray result = response.getJSONArray("result");
for (int i = 0; i < result.length(); i++) {
JSONObject jsonObject = result.getJSONObject(i);
String name = jsonObject.getString("name");
String phone = jsonObject.getString("phone");
String email = jsonObject.getString("email");
String j = String.valueOf(i);
data = new String[][]{{j, name, email, phone}};
tableView.setDataAdapter(new SimpleTableDataAdapter(getActivity(), data));
}
My json array
{
"result": [
{
"sl": "36",
"user_id": "575512",
"email": "m#gmail.com",
"password": "123",
"name": "Moderator",
"gender": "Male",
"phone": "1223345",
"lvl": "Moderator",
"stat": "1"
},
{
"sl": "68",
"user_id": "814769",
"email": "m2#gmail.com",
"password": "1WCcvnhp",
"name": "Test Moderator",
"gender": "Male",
"phone": "7412589630",
"lvl": "Moderator",
"stat": "1"
}
]
}
The problem is I am getting only the last value from jsonArray, because the String array is resetting itself.
data = new String[][]{{j, name, email, phone}};
I want to get all the values available in the jsonArray.
I am using the following dependencies for table
de.codecrafters.tableview:tableview:2.8.0
Try like this
JSONArray result = response.getJSONArray("result");
for (int i = 0; i < result.length(); i++) {
JSONObject jsonObject = result.getJSONObject(i);
String name = jsonObject.getString("name");
String phone = jsonObject.getString("phone");
String email = jsonObject.getString("email");
String j = String.valueOf(i);
data = new String[][]{{j, name, email, phone}};
}
tableView.setDataAdapter(new SimpleTableDataAdapter(getActivity(), data));
After getting all values in array, add that array to tableview
How to get this Json key and value from the web. This is my code, but I can't get this from the second iteration. can some one help me to do this.
Json Response :
"attributes": [
{
"main_id": "3",
"Color": [
{
"id": "60",
"text": "46( +$0.00)"
}
]
},
{
"main_id": "21",
"dede": [
{
"id": "73",
"text": "baba( +$0.00)"
}
]
}
]
This is my android code to parse the values :
JSONArray jsonArrayAttributes = jsonObj.getJSONArray("attributes");
for (int i = 0; i < jsonArrayAttributes.length(); i++) {
JSONObject jsonObject1 = jsonArrayAttributes.getJSONObject(i);
Iterator iteratorKey = jsonObject1.keys();
String strAttrId = (String) iteratorKey.next();
String strAttrName = (String) iteratorKey.next();
JSONArray jsonArrayName = jsonObject1.getJSONArray(strAttrName);
for (int j = 0; j < jsonArrayName.length(); j++) {
JSONObject jsonObjName = jsonArrayName.getJSONObject(j);
}
}
You have to change your code little bit like
JSONArray jsonArrayAttributes = jsonObj.getJSONArray("attributes");
for (int i = 0; i < jsonArrayAttributes.length(); i++) {
JSONObject jsonObject1 = jsonArrayAttributes.getJSONObject(i);
Iterator it = jsonObject1.keys();
boolean arrFlag = false;
while (it.hasNext()) {
String key = (String) it.next();
if (!arrFlag) {
String value = jsonObject1.getString(key);
Log.i("Key:Value", "" + key + ":" + value);
arrFlag = true;
} else {
JSONArray value = jsonObject1.getJSONArray(key);
Log.i("Key:Value", "" + key + ":" + value);
arrFlag = false;
}
}
}
It working perfectly.
You will get all keys and value over here.
I am building an Android app and are collecting data from my remote API (using Volley)
and I need to parse the response. I know how to get the "projects" array but how can I get the title for each project (please note the project key for each project).
{
"code": 200,
"total": 4,
"projects": [
{
"project": {
"id": 1,
"title": "A nice long title",
"latitude": 56.0293783,
"longitude": 12.7256732,
"created_at": "2013-10-20T20:57:00+02:00",
"created_at_human": "5 months",
"total_tasks": 7,
"description": "This is a description.",
"address": "simple highway 22",
"zipcode": "25656",
"city": "florida"
}
},
{
"project": {
"id": 2,
"title": "A nice long title",
"latitude": 56.0293783,
"longitude": 12.7256732,
"created_at": "2013-10-20T20:57:00+02:00",
"created_at_human": "5 months",
"total_tasks": 7,
"description": "This is a description.",
"address": "simple highway 22",
"zipcode": "25656",
"city": "florida"
}
}
]
}
This is the code I use now and that needs to be modified:
JSONArray jsonPosts = mData.getJSONArray("projects");
ArrayList<HashMap<String, String>> blogPosts = new ArrayList<HashMap<String, String>>();
for (int i = 0; i < jsonPosts.length(); i++) {
JSONObject post = jsonPosts.getJSONObject(i);
Log.e("OUTPUT", "THE POST: " + post);
}
This outputs:
E/OUTPUT﹕ THE POST: {"project":{"id":1,"title":"A nice long title","total_tasks":7,"address":"simple highway 22","description":"This is a description.","zipcode":"25656","created_at":"2013-10-20T20:57:00+02:00","longitude":12.7256732,"created_at_human":"5 MåNADER","latitude":56.0293783,"city":"florida"}}
How can I access the title for each?
Each jSONObject item contains a key and jSONObject. I think you need to get jSONObject from item in Array then get title and city.
I hope it will helpful for you........
JSONArray jsonPosts = mData.getJSONArray("projects");
ArrayList<HashMap<String, String>> blogPosts = new ArrayList<HashMap<String, String>>();
for (int i = 0; i < jsonPosts.length(); i++) {
JSONObject post = jsonPosts.getJSONObject(i);
JSONObject innerjson = post.getJSONObject("project");
String title = innerjson.getString(KEY_TITLE);
title = Html.fromHtml(title).toString();
String city = innerjson.getString(KEY_CITY);
city = Html.fromHtml(city).toString();
HashMap<String, String> blogPost = new HashMap<String, String>();
blogPost.put(KEY_TITLE, title);
blogPost.put(KEY_CITY, city);
blogPosts.add(blogPost);
}
String[] keys = {KEY_TITLE, KEY_CITY};
int[] ids = { R.id.top_label, R.id.bottom_label};
SimpleAdapter adapter = new SimpleAdapter(this, blogPosts, R.layout.list_item, keys, ids);
setListAdapter(adapter);
This is a JSONArray and not a JSONObject - to make a JSONObject from it, use
JSONObject jsonObject = jsonArray.getJSONObject(0);
this gets the first JSONObject from this JSONArray.
If you have multiple JSONObjects, use this:
JSONObject jsonObject;
for(int n = 0; n < jsonArray.length(); n++)
{
jsonObject = jsonArray.getJSONObject(n);
}
To get the values:
jsonObject.getString("name");
Help me parsing JSON. I parse this JSON without "moment" and don't know how parse with "moment".
My JSON response:

This code is parse response without "moment". How to parse response with "moment" and save it in array?
JSONObject jsonResponse = new JSONObject(jsonResult);
for (int j=0; j<8; j++){
String[] groupName = {"A", "B", "C", "D", "E", "F", "G", "H"};
JSONArray jsonMainNode = jsonResponse.optJSONArray(groupName[j]);
if (jsonMainNode.length() == 0){ continue;}
else {
for (int i = 0; i < jsonMainNode.length(); i++) {
JSONObject jsonChildNode = jsonMainNode.getJSONObject(i);
team1 = jsonChildNode.optString("team1");
team2 = jsonChildNode.optString("team2");
group = jsonChildNode.optString("group");
int live = jsonChildNode.getInt("live");
String time = null;
if (live == 1){
time = jsonChildNode.optString("time0_90")+"'";
score = jsonChildNode.optString("score");
}
else {
score = jsonChildNode.optString("time");
referee = jsonChildNode.optString("referee");
time = jsonChildNode.optString("stadium");
}
try this :
jsonArray moment = json.getJsonArray("B").getJsonObject(0).getJsonArray("moment");
String class = moment.getString("class_moment");
String name= moment.getString("name1");
String time= moment.getString("time0_90Moment");
String team= moment.getString("team");
I would recommend that you use a JSON Mapping library, like Jackson or GSON, manually parsing JSON is a waste of time and effort unless it is purely for educational purposes.
Other than that I assume the correct usage would be .optJSONArray("moment") follow by an iteration with a cast of each result to JSONObject or similar? Manually doing this is just a mess. ;o
I did it, here's the code
JSONObject jsonResponse = new JSONObject(jsonResult);
for (int j=0; j<8; j++){
String[] groupName = {"A", "B", "C", "D", "E", "F", "G", "H"};
JSONArray jsonMainNode = jsonResponse.optJSONArray(groupName[j]);
if (jsonMainNode.length() == 0){ continue;}
else {
for (int i = 0; i < jsonMainNode.length(); i++) {
JSONObject jsonChildNode = jsonMainNode.getJSONObject(i);
team1 = jsonChildNode.optString("team1");
team2 = jsonChildNode.optString("team2");
group = jsonChildNode.optString("group");
int live = jsonChildNode.getInt("live");
String time = null;
if (live == 1){
time = jsonChildNode.optString("time0_90")+"'";
score = jsonChildNode.optString("score");
JSONArray jsonMoment = jsonChildNode.optJSONArray("moment");
if (jsonMoment == null)
{
class_moment=new String[1];
name1 = new String[1];
name2 = new String[1];
name1 = new String[1];
time0_90Moment = new String[1];
team = new int[1];
}
else {
class_moment=new String[jsonMoment.length()];
name1 = new String[jsonMoment.length()];
name2 = new String[jsonMoment.length()];
name1 = new String[jsonMoment.length()];
time0_90Moment = new String[jsonMoment.length()];
team = new int[jsonMoment.length()];
for (int k = 0; k < jsonMoment.length(); k++) {
JSONObject jsonChildMoment = jsonMoment.getJSONObject(k);
class_moment[k] = jsonChildMoment.optString("class_moment");
name1[k] = jsonChildMoment.optString("name1");
name2[k] = jsonChildMoment.optString("name2");
time0_90Moment[k] = jsonChildMoment.optString("time0_90Moment");
team[k] = jsonChildMoment.getInt("team");
}}
}
else {
score = jsonChildNode.optString("time");
referee = jsonChildNode.optString("referee");
time = jsonChildNode.optString("stadium");
}
