I have a JSON Array as follows:
jSONArray: {"li":[["apple\r\n","orange\r\n","mango\r\n"]]}
I want only the list as [apple, orange, mango] in android. Can anybody explain how to parse it in android without \r\n. I have tried as follows:
JSONArray jsonArray1 = new JSONArray(results.toString()); // which is the JSON Array
for(int i=0; i < jsonArray1.length(); i++) {
JSONObject jsonobject = new JSONObject();
JSONObject issue = jsonArray1.getJSONObject(i);
String _pubKey = issue.getString("li");
}
So, I am getting pubKey as [["apple\r\n","orange\r\n","mango\r\n"]]. I dont want \r\n.
Just replace those characters while parsing.
Example: If fruit is the string you want to put in your JSONArray jsonArray, call:
jsonArray.put(fruit.trim().replace("\r", "").replace("\n", ""));

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.
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.
I am trying to pass some json encoded data from cakephp to android, I have a problem when passing the data
I use
echo json_encode($todaysdata);
exit();
in CakePhp and when I debug this code in cakephp, I get a result in the browser
[{"status":{"uname":"sibin","pass":"shanu","upid":14}},
{"status": {"uname":"amal","pass":"amalu","upid":14}}
]
I need to extract these two status details seperately in Android
I tried one code in android, it gives result, but result is repeated
I want the result of two status seperately
If anybody know, please help me.
set status value as from current json String :
JSONArray jsonarr = new JSONArray("your json String");
for(int i = 0; i < jsonarr.length(); i++){
JSONObject jsonobj = jsonarr.getJSONObject(i);
// get status JSONObject
JSONObject jsonobjstatus = jsonobj.getJSONObject("status");
// get uname
String str_uname=jsonobjstatus.getString("uname");
// get pass
String str_pass=jsonobjstatus.getString("pass");
// get upid
String str_upid=jsonobjstatus.getString("upid");
}
Try with the following code.
JSONArray jsonArray = new JSONArray("yourJsonResponseInString");
for(int i=0;i<jsonArray.length();i++)
{
JSONObject e = jsonArray.getJSONObject(i);
JSONObject jsonObject = e.getJSONObject("status");
Log.i("=== UserName","::"+jsonObject.getString("uname"));
Log.i("=== Password","::"+jsonObject.getString("pass"));
Log.i("=== UId","::"+jsonObject.getString("upid"));
}
I got the Json response. I am not able to get the values from the string.my string is
Json_response is
{"NameAllList":[{"Current":{"time":"2012-02-21T08:04:21","Name":"abcd"},
"Next":{"Name":"data1","StartTime":"2012-02-21T08:06:21"}},{"Current":{"time":"2012-02-21T08:14:21","Name":"defg"},
"Next":{"Name":"data2","StartTime":"2012-02-21T08:24:21"}},{"Current":{"time":"2012-02-21T08:28:21","Name":"ghij"},
"Next":{"Name":"data3","StartTime":"2012-02-21T08:34:21"}},{"Current":{"time":"2012-02-21T08:40:21","Name":"knmo"},
"Next":{"Name":"data4","StartTime":"2012-02-21T08:48:21"}}]}
and i tried this.
JSONObject jsonObj = new JSONObject(json_response);
JSONObject subObj = jsonObj.getJSONObject("Current");
String name_current =subObj.getString("Name");
but i am not able to get the value of "Name". what mistake i have done. provide the link to do the above parsing.
first of all, your JSON response is having NameAllList as a JSON Array of objects.
So you have to fetch JSON Array first, then you can fetch one-by-one object.
for example:
JSONObject jsonString = (new JSONObject(json_response_string));
JSONArray array = jsonString.getJSONArray("NameAllList");
for(int i=0; i<array.length(); i++)
{
// Retrieve Current object as such
JSONObject objCurrent = array.getJSONObject("Current");
// Retrieve Next object as such
JSONObject objNext = array.getJSONObject("Next");
}
You are not parsing json properly, so you are not able to fetch value of Name. Please note JSON Annotation [] represent JSONArray, and {} respresent JSONObject, so method to get current item's name is:
JSONObject jsonObj = new JSONObject(json_response_string);
JSONArray jsonArr=jsonObj.getJSONArray("NameAllList");
String Hora_name_current="";
for(int i=0;i<jsonArr.length();i++)
{
JSONObject obj=jsonArr.get(i);
try{
JSONObject subObj = obj.getJSONObject("Current");
Hora_name_current =subObj.getString("Name");
break;
}catch(JSONException ex)
{
}
}
looks like you're trying to use JSONObject when you should be using JSONArray for the second request. Try this:
JSONObject jsonString = (new JSONObject(json_response_string));
JSONArray array = jsonString.getJSONArray("NameAllList");
In your JSON return, "NameAllList is actually an array and needs to be handled as such. Once you set it to "array", you can then run a for loop and treat it like any other array in Java.
Let me know if that helps.
David
JSONObject jsonObj = new JSONObject(json_response_string);
JSONArray jsonArray = jsonObj.getJSONArrays("NameAllList");
