here data URL is your web service link.
POST array list from android application to php page
Try like this.
Map<String,Object> productimages = new HashMap<String, Object>();
List<String> datas = new ArrayList<String>();
datas.add("image");
datas.add("small_image");
datas.add("thumbnail");
productimages.put("types",datas);
If your using nemevalue pair use like this.
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("colors[]","red"));
nameValuePairs.add(new BasicNameValuePair("colors[]","white"));
nameValuePairs.add(new BasicNameValuePair("colors[]","black"));
nameValuePairs.add(new BasicNameValuePair("colors[]","green"));
How to send Arraylist of class in POST method of WCF webservice from android
use jackson library to create json string from array list of class object and after that send it. I have done successfully with this.
public String sendArrayListOfuserclass() {
String request_string = null;
HttpClient client = new DefaultHttpClient();
HttpConnectionParams.setConnectionTimeout(client.getParams(), 10000); // Timeout
HttpResponse response;
try {
HttpPost post = new HttpPost(
ServiceConstant.ALL_PERSON_UPDATE_DETAIL_URL);
post.setHeader("Content-type", "application/x-www-form-urlencoded");
DatabaseHelper mDatabaseHelper = DatabaseHelper
.getInstance(sContext);
List<PersonInformationBean> allPersonDetailList = mDatabaseHelper
.getAllPersonDetail();
List<ActivationBean2> PersonRequest = new ArrayList<ActivationBean2>();
int size = allPersonDetailList.size();
if (size > 0) {
for (PersonInformationBean personInformationBean : allPersonDetailList) {
ActivationBean2 personactivationdata = new ActivationBean2();
try {
personactivationdata.setPersonID(personInformationBean
.getPersonId());
personactivationdata
.setActivationKey(personInformationBean
.getActivationKey());
} catch (Exception e) {
}
PersonRequest.add(personactivationdata);
}
}
RefreshPersonBean personwithdeviceid = new RefreshPersonBean();
personwithdeviceid.setPersonRequest(PersonRequest);
personwithdeviceid.setDeviceID(MyPreferences.getInstance(sContext)
.getDeviceId());
request_string = convertBeanToJson(personwithdeviceid);
request_string = request_string.replace("\\", "")
.replace("\"[", "[").replace("]\"", "]");
request_string = request_string.replace("\n", "").replace("\r", "");
Log.e("referesh person request", request_string);
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
nameValuePairs.add(new BasicNameValuePair(
ServiceConstant.RequestData, request_string));
post.setEntity(new UrlEncodedFormEntity(nameValuePairs, "UTF-8"));
// post.setEntity(new ByteArrayEntity(json.toString().getBytes()));
response = client.execute(post);
/* Checking response */
if (response != null) {
InputStream inputStream = response.getEntity().getContent(); // Get
request_string = convertStreamToString(inputStream);
Log.e("response",
"response of post = " + request_string.toString());
return request_string;
}
} catch (IOException e) {
request_string = "timeout";
e.printStackTrace();
} catch (Exception e) {
// Toast.makeText(sContext, "Server Error",
// Toast.LENGTH_LONG).show();
e.printStackTrace();
}
return request_string;
}
this is jackson library function:
private String convertBeanToJson(RefreshPersonBean bean) {
String reqQuery = null;
try {
reqQuery = mapperObj.writeValueAsString(bean);
Log.d("convertBeanToJson(): request query is:", reqQuery);
} catch (JsonGenerationException e) {
Log.e("convertBeanToJson():", " caught JsonGenerationException");
} catch (JsonMappingException e) {
// mELogger.error("convertBeanToJson(): caught JsonMappingException");
} catch (IOException e) {
Log.e("convertBeanToJson():", " caught IOException");
}
return reqQuery;
}//
library name jackson-all-1.6.2
Getting MultiDimensional Array from JSONArray(PHP to ANDROID)
String s = "[{\"index\":1,\"questions\":\"If the number of berths in a train are 900 more than one-fifth of it, find the total berths in the train?\",\"options\":[\"1145\",\"1130\",\"1135\",\"1125\",\"1120\"],\"answers\":\"1125\",\"useranswers\":\"1145\"}]";
try {
JSONArray a;
a = new JSONArray(s);
JSONObject o = (JSONObject) a.get(0);
JSONArray options = o.getJSONArray("options");
} catch (JSONException e) {
// TODO Auto-generated catch block

How to populate ArrayList after getting it from the webservice in Android
Your method should be declared as private ArrayList<?> callWebService() and you should return your arrayList from that method when you are done.
Also as mentioned above you should check if your result object is returned as Vector. If it is returned as Vector modify it to ArrayList.
Finally, in the doInBackround of your AsyncTask you should change your return null code to return callWebService(); since your callWebService() method will return the result ArrayList with the above modification. Then in your onPostExecute(ArrayList<?> result) the result variable will not be null but will have the result ArrayList from your webservice.
So with the bove modifications you will have something like this:
private ArrayList<?> callWebService() {
...
try {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER12);
envelope.dotNet = false;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.call(SOAP_ACTION,envelope);
result = envelope.getResponse();
if (result instanceof ArrayList<?>) {
ArrayList<?> weatherList = (ArrayList<?>)result;
for (int i=0; i<weatherList.size(); i++)
Object weekDay = weatherList.get(i);
System.out.println();
}
} else {
}
return result;
} catch (SocketTimeoutException e) {
Toast.makeText(mainActivity, "Service is not connected, Please make sure your server is running", Toast.LENGTH_LONG).show();
} catch(Exception e) {
e.printStackTrace();
}
} //end of callWebService()
The AsyncTask:
public class MyTask extends AsyncTask<Void, Void, ArrayList<?>> {
ProgressDialog dialog = null;
Object result = null;
MainActivity mainActivity;
public MyTask(MainActivity mainActivity) {
this.mainActivity = mainActivity ;
}
@Override
protected void onPreExecute() {
super.onPreExecute();
if (dialog == null) {
dialog = new ProgressDialog(mainActivity);
}
dialog.setMessage("Please Wait. Your authentication is in progress");
dialog.show();
} //end of onPreExecute()
@Override
protected ArrayList<?> doInBackground(Void... params) {
return callWebService();
} //end of doInBackground()
@Override
protected void onPostExecute(ArrayList<?> result) {
super.onPostExecute(result);
dialog.dismiss();
} //end of onPostExecute()
} //end of class MyTask
You can change your Vector to Array list with something like this:
ArrayList<WeekDays> arraylist = new ArrayList<WeekDays>();
Collectios.copy(arraylist, vector_containing_the_data);
Edit(Basit)
---------------------------------------------------------------
@Override
protected void onPostExecute(Vector<?> result) {
super.onPostExecute(result);
if (result != null) {
for (int i=0; i<result.size(); i++) {
Object weekDay = result.get(i);
if (weekDay instanceof SoapObject) {
SoapObject weekDayObject = (SoapObject)weekDay;
String objectName = weekDayObject.getName(); //WeekDays
String dayName = weekDayObject.getProperty("name").toString();
String weather = weekDayObject.getProperty("weather").toString();
String temp = weekDayObject.getProperty("temperature").toString();
} //end of if (weekDay instanceof SoapObject)
} //end of for (int i=0; i<result.size();...)
} //end of if (result != null)
dialog.dismiss();
} //end of onPostExecute()
But i think this should be done in the doBackGround() method and after populating the values in the bean. Then i should use that bean in my onPostExecute() method, to update the UIThread. But this code is working fine for me.
