Converting from JSONArray to String then back again
(1 answer)
Closed 6 years ago.
JSONArray array = new JSONArray();
try
{
for (int i = 0; i < contactList.size(); i++){
JSONObject obj = new JSONObject();
String myString = contactList.get(i);
Log.e("Contact List",contactList.get(i));
String[] myarray = myString.split(",");
obj.put("is_private","0");
obj.put("expire_date","0000-00-00");
obj.put("name",myarray[0]);
obj.put("phone_no",myarray[1]);
obj.put("user_id", 1);
array.put(obj);
}
how we can convert json string to normal string ? please give me answer.
You can used toString function for this.
array.toString()
JSONObject obj = new JSONObject(yourstring);
String x = obj.getString("x");
Use this code, may help you.
JSONObject json = new JSONObject();
//put your values
json.toString();
clear your question please
JsonObject to String use:
json.toString();
String to JsonObject:
String data= "Json format data";
JsonObject obj=new JsonObject(data);

i need help to parse this json code to actual strings using android volley. this is the json code:[{"name":"Tayo","0":"Tayo","thread_name":"Welcome","1":"Welcome","post":"Hi there,","2":"Hi there,","post_time":"Sunday","3":"Sunday"},{"name":"Pete","0":"Pete","thread_name":"Welcome","1":"Welcome","post":"Hi,am pete","2":"Hi,am pete","post_time":"Monday","3":"Monday"}].
I have tried other helps but not working. Thanks!
Remember:
if the .json content starts with { is considered as a Json Object.
if the .json content starts with [ is considered as a Json Array.
so you hava a JsonArray then you can parse your content like this way:
//Obtain the JsonArray
JSONArray jsonArray = new JSONArray(myJsonContent);
// Get the JsonObjects inside JsonArray
for(int i=0;i<jsonArray.length();i++){
JSONObject jsonobject = jsonArray.getJSONObject(i);
}
// strData is the json data received.
JSONArray jsonArray = new JSONArray(strData);
for (int i=0; i<jsonArray.length();i++){
JSONObject jsonObject = jsonArray.getJSONObject(i);
String name = jsonObject.optString("name");
String zero = jsonObject.optString("0");
String thread_name = jsonObject.optString("thread_name");
String one = jsonObject.optString("1");
String post = jsonObject.optString("post");
String two = jsonObject.optString("2");
String post_time = jsonObject.optString("post_time");
String three = jsonObject.optString("3");
//Just an example
arrayName.add(jsonObject.optString("name"));
}
You can even use array to store data instead of the string.
{"success":"true",
"groups":[
{
"groupId":"c20f2353-1f13-4ea0-8283-ghhjc4dcc725251b",
"name":"hb",
"description":"hjj",
"image":null,
"membersCount":1,
"groupType":"chaddt",
"productCategeory":"bdfjgh",
"members":[
{
"memberId":"0031ea31-a71c-49f8ddbff6-8adaa310db02",
"memberName":"ddddsnta",
"contactId":"5a303564dd-2349-4cca-a190-f36f28ff54cb",
"contactName":"dssnta",
"role":"member"
}
],
}
]
}
This is my json.I am having some difficulty in parsing this.I am trying this solution.please suggest some ideas how to parse this type of json.Thanks for your answer
JSONArray jsonArray = jsonObject.getJSONArray("groups");
for (int i = 0; i < jsonArray.length(); i++) {
groupid = jsonArray.getJSONObject(i).getString("groupId");
String name = jsonArray.getJSONObject(i).getString("name");
String description =jsonArray.getJSONObject(i).getString("description");
String membersCount = jsonArray.getJSONObject(i).getString("membersCount");
String intrested = jsonArray.getJSONObject(i).getString("productCategeory");
JSONArray memberJsonArray = jsonArray.getJSONObject(i).getJSONArray("members");
for (int j = 0; j < memberJsonArray.length(); j++) {
String memberNamename = memberJsonArray.getJSONObject(j).getString("contactName");
String contactId = memberJsonArray.getJSONObject(j).getString("contactId");
String role = memberJsonArray.getJSONObject(j).getString("role");
GroupsDto groupDtoData = new GroupsDto();
groupDtoData.setGroupName(name);
groupDtoData.setGroupServerId(groupid);
System.out.println("groupid"+groupid);
groupDtoData.setGroupDescription(description);
groupDtoData.setProductCategory(intrested);
System.out.println("descr"+intrested);
groupDtoData.setGetmemberCount(membersCount);
groupDtoData.setGroupmembername(memberNamename);
System.out.println("membernames"+memberNamename);
groupDto.add(groupDtoData);
db.addGroups(groupDtoData);
}

Your JSON response does not have any array name.
Instead of this :
JSONArray jsonArray = jsonObject.getJSONArray("groups");
Use This:
JSONArray jsonArray = jsonObject.getJSONArray(yourResponseStringHere);
It just needed to use Gson library and create corresponding class with your json file.
Gson : https://github.com/google/gson
Check this answer .It may help you fixing this.
JsonArray jarray=response.getJsonArray("groups");
for(int i=0;i<jarray.length();i++)
{
JsonObject jobj=jarray.getJsonObject(i);
String groupId=jobj.optString("groupId");
//do like this for all
//to get members
JsonArray jarray2=jobj.getJsonArray("members");
for(int j=0;j<jarray2.length();j++)
{
JsonObject jobj2=jarray2.getJsonObject(j);
String memberId=jobj2.optString("memberId");
//do this for all
}
}
I have data on this string, but I'm having trouble to access the individual data.
This is my code:
Log.d("Detail Outputss", "" + response.toString());
And this is the string output:
{"futsal_id":"45","info":[{"futsal_id":"45","futsal_name":"Kathmandu Futsal","city":"Kathmandu","address":"Kathmandu","owner_name":"Hari Prasad","owner_address":"Kathmandu","email":"kathmandufutsal#gmail.com","password":"kathmandu","phone_no":"1111111","mobile_no":"9841112233","status":"1"}],"description":[{"futsal_id":"45","futsal_desc":"Futsal is the fever which never ends.\r\nKathmandu futsal is - a platform, a medium of communication for our fraternity.

I want to get the value of each object futsal_id, futsal_name, city and others, thanks in advance!!
It is JSONArray within a JSONObject
JSONObject json = new JSONObject(response);
JSONArray info = json.getJSONArray("info");
//getting the first value.. loop it if you have more than one
JSONObject infoObject = info.getJSONObject(0);
JSONArray description = json.getJSONArray("description");
JSONObject json = new JSONObject(response);
int fustal_id =Integer.parseInt(json.getString("futsal_id"));
JSONArray inf = json.getJSONArray("info");
JSONObject info = inf.getJSONObject(0);
...
JSONObject responseObject = new JSONObject(response);
JSONArray info = responseObject.getJSONArray("info");
for(int i = 0; i < info.length(); i++) {
JSONObject obj = info.getJSONObject(i);
String futsal_id = obj.getString("futsal_id");
String futsal_name = obj.getString("futsal_name");
//so on
}
Be sure to catch the exceptions.
I'm trying to parse the following JSON string
String _message = "GetXTRONResult: \"[{\"xtron\":\"Acub1\"},{\"xtron\":\"Acub2\"},{\"xtron\":\"Acub3A\"}]\"";
JSONObject jsonObj = new JSONObject(_message);
//Try to convert to array
JSONArray array = jsonObj.getJSONArray("GetXTRONResult"); //FAILS !
What is the best way to parse the above please?
UPDATE:
This is what the value is during debugging:
{"GetXTRONResult":"[{\"xtron\":\"Acub1\"},{\"xtron\":\"Acub2\"},{\"xtron\":\"Acub3A\"}]"}
org.json.JSONException: Value .... at GetXTRONResultof type java.lang.String cannot be converted to JSONArray
SOLUTION THAT WORKED FOR ME:
I had to use the iterator as follows:
ArrayList list = new ArrayList();
JSONObject jsonObj = new JSONObject(_message);
Iterator<?> keys = jsonObj.keys();
if (keys.hasNext()) {
JSONArray array = new JSONArray((String) jsonObj.get((String) keys.next()));
for (int i = 0; i < array.length(); ++i) {
list.add(array.getJSONObject(i).getString("xtron").toString());
}
You have some errors in your json string, like "[.
You can't use quotes that wrap your list.
This one should work:
String _message = "{\"GetXTRONResult\": [{\"xtron\":\"Acub1\"},{\"xtron\":\"Acub2\"},{\"xtron\":\"Acub3A\"}]}";
JSONObject jsonObj = new JSONObject(_message);
//Try to convert to array
JSONArray array = jsonObj.getJSONArray("GetXTRONResult");
System.out.println(array);
Output: [{"xtron":"Acub1"},{"xtron":"Acub2"},{"xtron":"Acub3A"}]
To avoid your confusion when making JSON in java/android
you could use single quote (') instead of double quote (") for JSON inside Java Code
For example:
from
"{\"xtron\":\"Acub1\"},{\"xtron\":\"Acub2\"},{\"xtron\":\"Acub3A\"}"
to be something like this
"{'xtron':'Acub1'},{'xtron':'Acub2'},{'xtron':'Acub3A'}"
I think this is what you're looking for:
JSONObject rootObj = new JSONObject(jsonString);
String theArrayJSON = rootObj.getJSONArray("GetXTRONResult");
JSONObject theArray = new JSONObject(theArrayJSON);
I'm trying to take the following string that I got as a json object:
[
{
"id": "picture1",
"caption": "sample caption",
"picname": "sample picture name"
}
]
and turn it into a array so I can populate a list
I've tried turning it into a jsonarray by doing this:
JSONArray myjsonarray = myjson.toJSONArray(string_containing_json_above);
but that didn't seem to work.
==============
Here is full code with the working solution
myjson = new JSONObject(temp);
String String_that_should_be_array = myjson.getString("piclist");
JSONArray myjsonarray = new JSONArray(String_that_should_be_array);
For(int i = 0; i < myjsonarray.length(); i++){
JSONObject tempJSONobj = myjsonarray.getJSONObject(i);
showToast(tempJSONobj.get("caption").toString());
}
temp is the json from the server
Issue is here:
JSONArray myjsonarray = myjson.toJSONArray(temparray);
Solution:
JSONArray myjsonarray = new JSONArray(myJSON);
// myJSON is String
Now here you are having JSONArray, iterate over it and prepare ArrayList of whatever types of you want.
here you get JSONArray so change
JSONArray myjsonarray = myjson.toJSONArray(temparray);
line as shown below
JSONArray jsonArray = new JSONArray(readlocationFeed);
and after
JSONArray jsonArray = new JSONArray(readlocationFeed);
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject explrObject = jsonArray.getJSONObject(i);
explrObject.getString("caption");
}
JSONArray isn't working because the JSON you provided is not an array. You can read more about JSON syntax here: http://www.w3schools.com/json/json_syntax.asp
In the meantime, you could manually create your array by paring the JSON one string at a time.
JSONObject strings = new JSONObject(jsonString);
String array[] = new String[5];
if (jsonString.has("id"){
array[0] = jsonString.getString("id");
}
if (jsonString.has("caption"){
array[1] = jsonString.getString("caption");
}
...
etc.
