Spinner.getSelectedItem().toString returns string,but goes empty when passed in an API post request

I am new to android and don't know what approach I am following is right or wrong.What I am trying to do is to pass the value of two edittexts and one spinner to a API post request on a button click and get the required list of tolls from the response from that API created,and populate a recyclerview just below the clicked button.But the API returns a status 500 i.e. validation error telling the three fields are required.Can anyone tell me where I am doing wrong in accomplishing that task.
Here is my OneTimePaymentActivity.java

} else {

}
}
private void sendRequest() {
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, url, (String) null, new Response.Listener<JSONObject>() {
#Override

try {
progressDialog.show();
int status = response.getInt("status");
if (status == 200) {

oneTimePayModelArrayList.clear();

return params;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(MyApplication.getContext());
requestQueue.add(jsonObjectRequest);
}
});
}
}
I even tried to debug the app and see the values of the texts passed to the API.But even if the texts passed are non-empty,it always returns a status=500(validation error) instead of status=200(Successful response).

I struggled to find a solution to this for 3 hours,but could not find anything specific.Please tell me a correct way to do it.

Take value in String variable and set that variable global for class.
You should try this :
String spinnerItemText = parent.getItemAtPosition(position).toString();
Want integer value :
Int value=Integer.parseInt(spinnerItemText).

Have you tried
String text = spinner.getSelectedItem().toString();

Try this,
ArrayList<String> spinnerData = Arrays.asList(getResources().getStringArray(R.array.dd_vehicle_type));
spinnerData.get(spinner.getSelectedItemPosition());
Even I have had the same problem and this worked out for me.

Sorry for suuuuch a late reply, but I got busy somewhere and almost forgot that I had asked a question and wanted a solution for that ASAP.
And thanks a lot for posting such awesome answers to my question.
But I must tell you that I had found a working solution for my problem.
Here are the changes I have done to my code to make it work
OneTimePaymentActivity.java
The only major change I have made in the code are here
StringRequest stringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() { <-----------
i.e using the StringRequest instead of JsonObjectRequest
and here
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(stringRequest); <--------
progressDialog = new ProgressDialog(OneTimePayActivity.this);
progressDialog.setTitle("Please Wait...");
progressDialog.setMessage("Fetching data");
progressDialog.setCancelable(false);
progressDialog.show();
}
i.e passing stringRequest to RequestQueue above
}
The rest of the code is same.
If anyone is facing any difficulty understanding the changes I have made in the code, please leave a comment below.

check list with AsyncTask

I have problem when i get the list from server i want to check it, if it's any object there or not.
if there are object , appears in my layout text : there is no object after few seconds it's disappears
and show my list.
i want just if there is object will appear in my layout directly.
private class RetrieveTask extends AsyncTask> {
#Override
protected List<branch> doInBackground(String... params) {
manager = new SessionManager(getActivity().getApplicationContext());
manager.checkLogin();
HashMap<String, String> user = manager.getUserID();
String uid = user.get(SessionManager.KEY_uid);
// Intent intent= getActivity().getIntent(); // gets the previously created intent
//String type18 = intent.getStringExtra("key28");

here the postExcute
#Override

super.onPostExecute(result);
if (result != null) {
final itemAdapter adapter = new itemAdapter(getActivity().getApplicationContext(), R.layout.row_favmarkets, result);
lv.setAdapter(adapter);
}
}
}
this is my layout xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"

android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/textView28"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="40dp"
android:layout_marginTop="250dp"
android:text="There is no Markets in your Favourite List.."
android:textSize="24sp"
android:visibility="gone" />
</LinearLayout>
<ListView

<Button
android:text="Button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/button6"
android:layout_marginLeft="400dp" />

Suggested changes which will at first show nothing when the request is executed. Once completed, if the list is empty it'll show "There is no Markets in your Favourite List..", otherwise the list will show.
Part Layout XML:
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/linearLayout28">
<TextView
android:id="#+id/textView28"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="40dp"
android:layout_marginTop="250dp"
android:text="There is no Markets in your Favourite List.."
android:textSize="24sp"
android:visibility="gone" />
</LinearLayout>
Initialize linearLayout28:
LinearLayout linearLayout28 = findViewById(R.id.linearLayout28);
And changes for the AsyncTask:
private class RetrieveTask extends AsyncTask<Void, Void, List<branch>> {
#Override
protected void onPreExecute() {
super.onPreExecute();
lv.setVisibility(View.GONE);
linearLayout28.setVisibility(View.GONE);
}
#Override
protected List<branch> doInBackground(String... params) {
//Keep as your code
...
}
#Override
protected void onPostExecute(final List<branch> result) {
super.onPostExecute(result);
if (result != null && result.size() != 0) {
final itemAdapter adapter = new itemAdapter(
getActivity().getApplicationContext(),
R.layout.row_favmarkets, result);
lv.setAdapter(adapter);
lv.setVisibility(View.VISIBLE);
linearLayout28.setVisibility(View.GONE);
} else {
lv.setVisibility(View.GONE);
linearLayout28.setVisibility(View.VISIBLE);
}
}
}

You are basically on the solution but you should not update the user interface from your AsyncTask. Create an interface and implement it on the Activity. Let the activity to update the data on the UI when data is ready or show a message error.
As an example, define the interface in your AsyncTask like:
private TaskCallback listener = null;
public interface TaskCallback {
void OnTaskCompleted ();
}
public void setListener (TaskCallback listener) {
this.listener = listener;
}
When your task was completed:
#Override
public void onPostExecute (Void v) {
if (listener != null) {
listener.OnTaskCompleted ();
}
}
You can add parameters to your callback base on your needs.
At your Activity level:
public class YourActivity extends Activity implements YourTask.TaskCallback {
// When you execute your task add the reference to the listener
YourTask task = new YourTask (YourActivity.this);
task.setListener (YourActivity.this);
task.execute ();
#Override
public void OnTaskCompleted () {
// Update your screen or show an error message
}
}

and the result that I got from looping Utils.log("studio_name: " + studio_name) are :
studio_name: Dodi fit
studio_name: inu fit
studio_name: Vstudio
studio_name: Infovendor
studio_name: Seleb Fitnes One
studio_name: Riri Studio
studio_name: NF Studio
It means I already got all of it use looping.
But the problem is the result did not populate into listview (it show as one one last result NF Studio, the other did not appear).
What I need is populate this into 4 texview from country_info (I disable imageview) :
String studio_name, address, website, seo_url
What is the correct code to show/populate that into listview?

Add the values into a List and pass it to the Adapter class of your ListView inside onPostExecute()

You don't need a thread, that's the whole point of async.
List View code is in the for loop
UI code belongs to PostExecute() not doInBackground()
You reinitialized the list inside of the loop
Try like this:
private class SendfeedbackJob extends AsyncTask<String, Void, String> {
private static final String LOG_TAG = "CariStudio";
private ArrayList<Country> countryList = new ArrayList<Country>();
ProgressDialog dialog;
Bundle extras = getIntent().getExtras();
final String token= extras.getString("TOKEN");
#Override
protected String doInBackground(String... params) {
String areaid = params[0];
Utils.log("params 1:"+ areaid);
// do above Server call here
ArrayList<NameValuePair> postParameters = new ArrayList<NameValuePair>();
postParameters.add(new BasicNameValuePair("region_id", areaid ));
String responseString = null;
final String url_studio = Constant.URI_BASE_AVAILABLE_STUDIO+ "?token=" + token;
Utils.log("url studio:"+ url_studio);
try
{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url_studio);
// no idea what this does :)
httppost.setEntity(new UrlEncodedFormEntity(postParameters));
// This is the line that send the request
HttpResponse response = httpclient.execute(httppost);
Utils.log("response:"+ response);
HttpEntity entity = response.getEntity();
String responseAsText = EntityUtils.toString(entity);
Utils.log("daftar isi studio: " + responseAsText);
JSONArray json = new JSONArray(responseAsText);
for (int i = 0; i < json.length(); i++) {
jsonobject = json.getJSONObject(i);
final String studio_name = jsonobject.getString("studio_name");
final String address = jsonobject.getString("address");
final String website = jsonobject.getString("website");
final String seo_url = jsonobject.getString("seo_url");
Utils.log("studio_name: " + studio_name);
Country country = new Country(studio_name,address, "Website:"+ website,"Fasilitas:"+ seo_url);
countryList.add(country);
}
}
catch (Exception e)
{
/*Toast.makeText(context,
"user not registered", Toast.LENGTH_SHORT).show();*/
Log.e(LOG_TAG, String.format("Error during login: %s", e.getMessage()));
}
return "processing";
}
protected void onPostExecute(Boolean result) {
//dialog.cancel();
//create an ArrayAdaptar from the String Array
dataAdapter = new MyCustomAdapter(context,
R.layout.country_info, countryList);
//enables filtering for the contents of the given ListView
ListView listView = (ListView) findViewById(R.id.listView1);
// Assign adapter to ListView
listView.setAdapter(dataAdapter);
listView.setTextFilterEnabled(true);
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
Country country = (Country) parent.getItemAtPosition(position);
Toast.makeText(getApplicationContext(),
country.getCode(), Toast.LENGTH_SHORT).show();
Intent intent = new Intent(context, checkin.class);
startActivity(intent);
}
});
EditText myFilter = (EditText) findViewById(R.id.myFilter);
myFilter.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {
}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
public void onTextChanged(CharSequence s, int start, int before, int count) {
dataAdapter.getFilter().filter(s.toString());
}
});
}
}

ArrayAdapter never used ArrayList null and all items appear in single row

I am new to android and I am trying to create a list view using an array adapter, a run method and multi threading. The list displays all the data from an array list as a single row.
My MainActivity looks like this:
public class MainActivity extends FragmentActivity implements OnClickListener{
..
ArrayList<StorylineData> storylineData;
ArrayList<SummaryData> summary;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mSpinnerAPI = (Spinner) findViewById(R.id.spinnerAPI);
mButtonSubmit = (Button) findViewById(R.id.buttonSubmit);
mEditTextResponse = (ListView) findViewById(R.id.editResponse);
mProgressRequest = (ProgressBar) findViewById(R.id.progressRequest);
mButtonSubmit.setOnClickListener(this);
...
#Override
public void onClick(View v) {
toggleProgress(true);
switch (mSpinnerAPI.getSelectedItemPosition()) {
case 0: // Authenticate
...
case 4: // Get Summary Day
MovesAPI.getSummary_SingleDay(summaryHandler, "20150418", null);//Date changed to "20150117"
break;
...
case 10: // Get Storyline Day
MovesAPI.getStoryline_SingleDay(storylineHandler, "20150418", "20140714T073812Z", false);//Date changed to "20150418" "null changed to"20140714T073812Z"
break;
...
toggleProgress(false);
break;
}
}
...
private MovesHandler<ArrayList<StorylineData>> storylineHandler = new MovesHandler<ArrayList<StorylineData>>() {
#Override
public void onSuccess(ArrayList<StorylineData> result) {
toggleProgress(false);
updateResponse(
"Date:\t" + result.get(0).getDate() + "\n"
+ "-----------Activity 1 Summary--------\t" + "\n"
+ "Activity:\t" + result.get(0).getActivity().toString() + "\n"//returns 1587 with .getCaloriesIdle()
...
+ "-----------Activity 2 Summary---------\t" + "\n"
+ "Activity:\t" + result.get(0).getSummary().get(0).getActivity() + "\n"//returns 1587 with .getCaloriesIdle()
...
+ "-----------Segments---------\t" + "\n"
+ "Type:\t" + result.get(0).getSegments().get(0).getType() + "\n"//returns 1587 with .getCaloriesIdle()
...
}
public void updateResponse(final String message) {
MainActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
mButtonSubmit.setText(message);
StorylineAdapter adapter = new StorylineAdapter(MainActivity.this, R.layout.item_storyline, storylineData);
mEditTextResponse.setAdapter(adapter);
}
});
}
}
My ArrayAdapter class looks like this:
public class StorylineAdapter extends ArrayAdapter<SummaryData>{
private Context context;
private Runnable runnable;
private ArrayList<StorylineData> storylineData;
public StorylineAdapter(Context context, int resource, ArrayList<SummaryData> objects) {
super(context, resource, objects);
this.context = context;
this.runnable = runnable;
this.summary = objects;
}
#Override
public View getView(int position, View convertView, ViewGroup parent){
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.item_storyline, parent, false);
//Display in the TextView widget
SummaryData summary1 = summary.get(position);
TextView tv = (TextView) view.findViewById(R.id.textView1);
tv.setText(summary1.getActivity());
return view;
}
}
Here is my parser class:
public class StorylineData extends ArrayList<StorylineData> {
...Getters/Setters...
/**
* Parse a {#link org.json.JSONObject} from storyline {#link org.json.JSONArray}, then return the corresponding {#link StorylineData} object.
*
* #param jsonObject : the storyline JSON object received from server
* #return corresponding {#link StorylineData}
*/
public static StorylineData parse(JSONObject jsonObject) throws JSONException {
if (jsonObject != null) {
StorylineData storylineData = new StorylineData();
storylineData.date = jsonObject.optString("date");
storylineData.caloriesIdle = jsonObject.optInt("caloriesIdle");
storylineData.lastUpdate = jsonObject.optString("lastUpdate");
storylineData.summary = new ArrayList<SummaryData>();
storylineData.segments = new ArrayList<SegmentData>();
/**Get the data associated with the array named summary **To get a specific JSONArray: Summary*/
JSONArray summariesJsonArray = jsonObject.optJSONArray("summary");
if (summariesJsonArray != null)
for (int i = 0; i < summariesJsonArray.length(); i++) {
/**each time through array will need to get a reference of current object*/
JSONObject summaryJsonObject = summariesJsonArray.optJSONObject(i);
if (summaryJsonObject != null) {
/**===============Translate data from json to Java=================*/
/**Create a new OBJECT OF ARRAY STORYLINE/SUMMARY*/
ArrayList<SummaryData> summary = new ArrayList<SummaryData>(); // initialisation must be outside the loop
storylineData.setSummary(summary);
/**Get summary from json into java*/
summariesJsonArray.getJSONObject(i).getString("distance");
/**Get date from json into java*/
String date = summaryJsonObject.optString("date");
storylineData.setDate(date);
/**Get group from json into java*/
String group = summaryJsonObject.optString("group");//Get name using key e.g. date
storylineData.setGroup(group);
...
storylineData.summary.add(SummaryData.parse(summaryJsonObject));
Log.d("StorylineDataCls \t sJo", summaryJsonObject.toString() + "Log\n");
System.out.println("print distance" + summariesJsonArray.getJSONObject(i).getString("distance"));
System.out.println("print summary" + summaryJsonObject);
}
}
JSONArray segmentsJsonArray = jsonObject.optJSONArray("segments");
if (segmentsJsonArray != null) {
for (int i = 0; i < segmentsJsonArray.length(); i++) {
JSONObject segment = segmentsJsonArray.optJSONObject(i);
if (segment != null) {
ArrayList<SegmentData> segments = new ArrayList<SegmentData>(); // initialisation must be outside the loop
storylineData.setSegments(segments);
String type = segment.optString("type");
storylineData.setType(type);
...
storylineData.segments.add(SegmentData.parse(segment));
Log.d("StorylineDataCls \t sSo", segment.toString());
}
}
}
return storylineData;
}
return null;
}
}
I'm wondering if the reason the items are appearing in a single row may be because of a problem in the layout files?
Main Layout.

Changed MainActivity to implement View.OnClickListener:
public class MainActivity extends FragmentActivity implements View.OnClickListener {
Removed ArrayAdapter and replaced updateResponse method with:
public void updateResponse(final String message) {
runOnUiThread(new Runnable() {
//MainActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
ListView mListView = (ListView) findViewById(R.id.list_view);
String[] stringArray = message.split("\n");
// This is the array adapter, it takes the context of the activity as a
// first parameter, the type of list view as a second parameter and your
// array as a third parameter.
ArrayAdapter<String> adapter = new ArrayAdapter<>(MainActivity.this, android.R.layout.simple_list_item_1, stringArray);
mListView.setAdapter(adapter);
}
});
}
