Get spinner data from WebService

I have created an Android application in that I am calling webservice that have attribute name and attribute value and I wants to display attribute value in Spinner and attribute name display in TextView. If attribute value is two then two arrylist is store. If attribute name is same in both list then store only one list. If attributename change then add new arraylist. Below is my code
//call webservice for product attribute
private class getCategoryProductAttribute extends AsyncTask<String, String, String> {
ProgressDialog pdLoading = new ProgressDialog(ProductDescriptionActivity.this);
StringBuilder result = null;
String response;
#Override
protected void onPreExecute() {
super.onPreExecute();
pdLoading.setMessage("Loding..");
pdLoading.setCancelable(false);
pdLoading.show();
}
#Override
protected String doInBackground(String... strings) {
if (pref.isLoggedIn() == true) {
constant_pref.getPrefData();
} else {
constant_pref.UserName = "remplastic#admin";
constant_pref.Password = "remplastic#admin";
constant_pref.AppVersion = getVersionInfo();
constant_pref.DataVersion = "1.0";
}
Webservice addressService = new Webservice();
String query = "<value><user_name>" + constant_pref.UserName + "</user_name>" +
"<user_password>" + constant_pref.Password + "</user_password>" +
"<product_id>" + Product_Id + "</product_id>" +
"<appversion_text>" + constant_pref.AppVersion + "</appversion_text>" +
"<dataversion_text>" + constant_pref.DataVersion + "</dataversion_text></value>";
try {
addressService.XmlPostData(ConstantUrl.Product_Attribute_Url, query);
result = addressService.getResponse();
response = result.toString();
} catch (Exception e) {
e.printStackTrace();
}
return response;
}
#Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
try {
if (response.length() > 0) {
int code = Integer.parseInt(XMLManualParser.getTagValue(ConstantUrl.TAG_CODE, response));
String msg = XMLManualParser.getTagValue("message", response);
if (code == 1) {
spinnerlist.clear();
ArrayList<String> productlist = XMLManualParser.getMultipleTagList(ConstantUrl.TAG_LIST, response);
for (int i = 0; i < productlist.size(); ++i) {
String responseContent = productlist.get(i);
HashMap<String, String> hashMap = new HashMap<String, String>();
hashMap.put("attr_name", XMLManualParser.getTagValue(ConstantUrl.attribute_name, responseContent));
hashMap.put("attr_value", XMLManualParser.getTagValue(ConstantUrl.attribute_value, responseContent));
hashMap.put("attr_dealerprize", XMLManualParser.getTagValue(ConstantUrl.product_dealerprice, responseContent));
hashMap.put("attr_retailer_prize", XMLManualParser.getTagValue(ConstantUrl.product_retaillerprice, responseContent));
spinnerlist.add(hashMap);
if (XMLManualParser.getTagValue(ConstantUrl.attribute_name, responseContent).toLowerCase().equalsIgnoreCase("print")) {
}
}
attribute_adapter.notifyDataSetChanged();
} else {
Toast.makeText(ProductDescriptionActivity.this, msg, Toast.LENGTH_SHORT).show();
}
attribute_adapter.notifyDataSetChanged();
}
} catch (Exception e) {
}
pdLoading.dismiss();
}
}

Multiple Async Tasks one after another Android

I'm trying to fetch data from server in saving in SQLite database through Async task on Splash. i have multiple tables on server and need to fetch one after another. I'm trying this way
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder().detectDiskReads().detectDiskWrites().detectNetwork()
.penaltyLog().build());
url = getResources().getString(R.string.url);
db = new SQLCont(context);
new asyn_Task1(Splash.this).execute();
}
public class asyn_Task1 extends AsyncTask<String, Void, Boolean> {
public asyn_Task1(Splash activiy) {
context = activiy;
}
#Override

super.onPostExecute(result);
new asyn_Task2(Splash.this).execute();
}
#Override

super.onPreExecute();
progressdialog = new ProgressDialog(Splash.this);
progressdialog.setTitle("Processing....");
progressdialog.setMessage("Please Wait.....1 /10");
progressdialog.setCancelable(false);
progressdialog.show();
}
#Override
protected Boolean doInBackground(String... params) {
postParameters.add(new BasicNameValuePair("001", data));
try {
CustomHttpClient.executeHttpGet("001");
} catch (Exception e1) {
e1.printStackTrace();
}
String response = null;
// call executeHttpPost method passing necessary parameters
try {
response = CustomHttpClient.executeHttpPost(
url,
postParameters);
// store the result returned by PHP script that runs
// MySQL query
String result = response.toString();
// parse json data
try {
JSONArray jArray = new JSONArray(result);
for (int i = 0; i < jArray.length(); i++) {
JSONObject json_data = jArray.getJSONObject(i);
id = json_data.getString("id");
st_name = " " + json_data.getString("name");
st_contact = json_data.getString("contact");
st_category = json_data.getString("Category");
st_address = json_data.getString("address");
Log.d("favourite_data", "" + id + st_name + st_contact
+ st_category + st_address);
db.adddata_hospital(context, st_name,st_contact,
st_category, st_address);
}
} catch (JSONException e) {
Log.e("log_tag", "Error parsing data " + e.toString());
}
} catch (Exception e) {
Log.e("log_tag", "Error in http connection!!" + e.toString());
}
return null;
}
}
public class asyn_Task2 extends AsyncTask<String, Void, Boolean> {
public asyn_Task2(Splash activiy) {
context = activiy;
}
#Override
protected void onPostExecute(Boolean result) {
super.onPostExecute(result);
new asyn_Task3(Splash.this).execute();
}
#Override
protected void onPreExecute() {
super.onPreExecute();
}
#Override
protected Boolean doInBackground(String... params) {
// some stuff here
}
return null;
}
}
public class asyn_Task3 extends AsyncTask<String, Void, Boolean> {
public asyn_blood_Group(Splash activiy) {
context = activiy;
}
#Override
protected void onPostExecute(Boolean result) {
super.onPostExecute(result);
progressdialog.dismiss();
}
#Override
protected void onPreExecute() {
super.onPreExecute();
}
#Override
protected Boolean doInBackground(String... params) {
// some stuff here
}
return null;
}
}
problem is that data is added for asyn_Task1 it repeated every time
expected out put
abc def ghi
jkl mno pqr
mno pqr stu
But getting output
abc def ghi
abc def ghi
abc def ghi

You will get your data based on your query. If you always execute same query then you will always get same data.
And from my point of view if possible single AsyncTask for that purpose. when all the query is completed then onpostExecute() callback will fired.

unable to dismiss progress bar in dialogfragment

I have a dialog fragment which consists of an AsyncTask class. I am able to show a progress bar inside the dialogfragment. But unable to stop it after some time. Is there any way?
class GetStatsFromUrl extends AsyncTask<String, String, String> {
//ProgressDialogFragment pf;
ProgressBar p = null;
String info, status;
JSONObject json, json1, json2;

ServiceHandler sh = new ServiceHandler();
jsonstring = sh.makeServiceCall(url1, ServiceHandler.GET);
System.out.println("Response: " + jsonstring);
if (jsonstring != null && jsonstring.length() > 0) {
try {
JSONObject questionsObject = new JSONObject(jsonstring);
JSONArray questionsArray = questionsObject
.getJSONArray("Table");
if (questionsArray != null && questionsArray.length() > 0) {
for (int i = 0; i < questionsArray.length(); i++) {
JSONObject innerQuestionObject = (JSONObject) questionsArray
.get(i);
String count = innerQuestionObject.getString("Count");
String result = innerQuestionObject.getString("Result");
if (result.equalsIgnoreCase("R")) {
correctanswered = count;
} else if (result.equalsIgnoreCase("Total Questions")) {
totalquestions = count;
} else if(result.equalsIgnoreCase("W")){
// notanswered = count;
wronganswered = count;
}
/* if(result.equalsIgnoreCase("W")){
wronganswered = count;
}*/
}
}
} catch (JSONException e) {
e.printStackTrace();
}
}else {

// p.setVisibility(View.GONE);
tvbookmarkcount.setText(totalquestions);
//tvquesunattempted.setText(notanswered);
tvcorrectanswered.setText(correctanswered);
tvwronganswered.setText(wronganswered);
}
}

try below code:-
#Override
protected void onPostExecute(String result) {
// TODO Auto-generated method stub
p.dismiss();
}
you must call dismiss when your task is complete (onPostExecute).

android:textColor="#000"
android:textSize="16sp" >
</TextView>

After spending 6 hours I come to know that I have to add one line
autocomplete.showDropDown();
in onpost of async

check this page
you may need to update the UI.
runOnUiThread(new Runnable(){
public void run(){
aAdapter = new ArrayAdapter<String>(getApplicationContext(),R.layout.item,suggest);
autoComplete.setAdapter(aAdapter);
aAdapter.notifyDataSetChanged();
}
});
