setContentView(R.layout.activity_main);
RequestQueue requestQueue;
requestQueue = Volley.newRequestQueue(this);

//making json object request
JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null, new Response.Listener<JSONObject>() {

news.setNewsUrl(newsUrl);
news.setContent(content);
newsList.add(news);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d("fine", "Something Wrong"+error);
Toast.makeText(MainActivity.this, "Something Wrong "+error, Toast.LENGTH_SHORT).show();
error.printStackTrace();
}
});
requestQueue.add(request);
}
}

Your API Key is Invalid please check your API key. Getting this response:
{"status":"error","code":"apiKeyInvalid","message":"Your API key is invalid or incorrect. Check your key, or go to https://newsapi.org to create a free API key."}

Maybe Your API key is not live, please check your API key status than again hit the api.

Refresh fragment setText attribute

I'm try to using the class Fragment all working well, but when try to use variable get from te server, the fragment dont update the values.
This is my code:
public class report_fragment extends Fragment {
private BarChart barChart;
private ListView list;
public RequestQueue queue;
private Float ris;
String cu;
Button bSave;
private String userID,email,name,surname,age,privilegi;

String risultato, disciplina;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
//just change the fragment_dashboard
//with the fragment you want to inflate
//like if the class is HomeFragment it should have R.layout.home_fragment
//if it is DashboardFragment it should have R.layout.fragment_dashboard
final View view = inflater.inflate(R.layout.fragment_report_fragment, container, false);
barChart = (BarChart) view.findViewById(R.id.bargraph);
tExer = (TextView) view.findViewById(R.id.tExerc);
tRis = (TextView) view.findViewById(R.id.tRis);
Bundle b = this.getArguments();
if (b != null) {
name = b.getString("name");
surname = b.getString("surname");
age = b.getString("age");
privilegi = b.getString("privilegi");
userID = b.getString("user");
}
Log.d("iduser2", "" + userID);

String meteo = out.getString("meteo");
String dataa = out.getString("data");
String risultato = out.getString("risultato");
String score = out.getString("punteggio");

return params;
}
};
RequestQueue queue = Volley.newRequestQueue(getActivity());
queue.add(postRequest);
}
}
I received the variables "risultato and disciplina" and I see the correct value just after navigating in this fragment at the second time.
Frist time I see the null variable.
I tried to use a refresh of the fragment but it doesn't work.
The bargraph working correctly, but the setText doesn't work. I tried to do the same like a bargraph I have a failure.
Does someone have a suggestion? Thanks.

You need to set the text inside your onResponse function. The values are not available until the network call is finished. So the onResponse function inside your Last function should look like this.
private void Last(final String ID) {
//final TextView gTextView = (TextView) findViewById(R.id.graph);
// gTextView.append(" entrato in Data");
Log.d("ciaoo","sei qui");
String url = "https://anto-mc.000webhostapp.com/last.php";
StringRequest postRequest = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
final ArrayList<BarEntry> barEntries = new ArrayList<>();
ArrayList<String> theDates = new ArrayList<>();
Log.d("ciaoo","sei qui2");
JSONArray jsonArray = new JSONArray(response);
for (int i = 0 ; i < jsonArray.length(); i++) {
JSONObject out = jsonArray.getJSONObject(i);
Log.d("ciaoo","sei qui2" +""+out);
String meteo = out.getString("meteo");
disciplina = out.getString("disciplina");
risultato = out.getString("risultato");
String score = out.getString("punteggio");
String tot= out.getString("tot");
Log.d("queryris",""+disciplina + " "+ risultato);
}
// Set the text here when it is available
tExer.setText(disciplina);
tRis.setText(risultato);
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener(){
#Override
public void onErrorResponse(VolleyError error) {
error.printStackTrace();
}
})
{
#Override
protected Map<String, String> getParams()
{
Map<String, String> params = new HashMap<String, String>();
params.put("userID", ID);
return params;
}
};
RequestQueue queue = Volley.newRequestQueue(getActivity());
queue.add(postRequest);
}
The key idea is to set the text after the values are available after your API call is returning with some values in it. When you are calling a server API, it is being executed in another thread other than the UI thread. It does not halt its execution inside the onCreateView function as you are expecting I think.
Hope that helps.

The code is working fine when testing in emulator-Android 7.1, API 25 but when I test same code in Real Device-Android 4.4.4, API 19 spinner is not showing. And there is no error message even

}

StringRequest stringRequest = new StringRequest(Request. Method.GET,Config.DATA_URL, new Response.Listener()
Use it in getData(). Because you wasn't specified Request.Method.GET
::OR::
You can use same like this:
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("action", "filter_location");
return params;
}
};
Then remove the parameter "action=filter_location" from url.

Why do these two strings ( company_id & branch_id ) equal null in MyRequestQueue_Drivers?

**
the parameters of volley (company_id && branch_id)
equal null although I got its real data before via MyRequestQueue_Company so it causes volley response is nullpointer exception
Why do company_id and branch_id equal null in MyRequestQueue_Drivers? How can I solve this?
public class CheckinActivity extends AppCompatActivity implements AdapterView.OnItemSelectedListener {
String company_id, branch_id;
Spinner driver_name_spinner;
private String User_URL = "http://example.com/api/user?token=";
private String Drivers_URL = "http://example.com/api/getDrivers?company_id=1&branch_id=15";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_checkin);
driver_name_spinner = (Spinner) findViewById(R.id.driver_name_spinner);
next = (Button) findViewById(R.id.next);
SharedPreferences sharedPref = getSharedPreferences("userinfo", getApplicationContext().MODE_PRIVATE);
final String token = sharedPref.getString("token", "");
final RequestQueue MyRequestQueue_Company = Volley.newRequestQueue(this);
// GET COMPANY_ID AND BRANCH_ID FORM API
StringRequest MyStringRequest_Company = new StringRequest(Request.Method.GET, User_URL + token, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d("response", response);
try {
JSONObject jsono = null;
jsono = new JSONObject(response);
JSONObject jarray = jsono.getJSONObject("user");
company_id = jarray.getString("company_id");
branch_id = jarray.getString("branch_id");
Log.d("User Data", "company_id " + company_id + "\tbranch_id " + branch_id);
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() { //Create an error listener to handle errors appropriately.
#Override
public void onErrorResponse(VolleyError error) {
//This code is executed if there is an error.
}
});
MyRequestQueue_Company.add(MyStringRequest_Company);
// CALL ANOTHER WEBSERVICES TO GET DRIVERS DATA
RequestQueue MyRequestQueue_Drivers = Volley.newRequestQueue(getApplicationContext());
StringRequest MyStringRequest_Drivers = new StringRequest(Request.Method.POST, Drivers_URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d("Drivers Response", response);
try {
JSONObject jsono = null;
jsono = new JSONObject(response);
JSONArray jarray = jsono.getJSONArray("Drivers");
List<String> drivers;
drivers = new ArrayList<String>();
for (int i = 0; i < jarray.length(); i++) {
JSONObject newobject = jarray.getJSONObject(i);
driver_name_txt = newobject.getString("name");
Log.d("Driver Name", driver_name_txt);
drivers.add(driver_name_txt);
}
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(getBaseContext(), android.R.layout.simple_spinner_item, drivers);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
driver_name_spinner.setAdapter(dataAdapter);
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() { //Create an error listener to handle errors appropriately.
#Override
public void onErrorResponse(VolleyError error) {
Log.d("Drivers Error",error.toString());
}
}) {
protected Map<String, String> getParams() {
Map<String, String> MyData = new HashMap<String, String>();
// BRANCH_ID AND COMPANY_ID ARE EQUAL NULL !?
MyData.put("branch_id", branch_id);
MyData.put("company_id", company_id);
Log.d("Last User Data", "company_id " + company_id + "\tbranch_id " + branch_id);
return MyData;
}
};
MyRequestQueue_Drivers.add(MyStringRequest_Drivers);
driver_name_spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long l) {
TextView tmpView = (TextView) driver_name_spinner.getSelectedView().findViewById(android.R.id.text1);
tmpView.setTextColor(Color.WHITE);
driver_name_txt = parent.getItemAtPosition(position).toString();
Log.d("driver_name_original", driver_name_txt);
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});

If you want to use getParams function, than I would suggest to define a flag and modify your function like:
#Override
public void onResponse(String response) {
Log.d("response", response);
try {
JSONObject jsono = null;
jsono = new JSONObject(response);
JSONObject jarray = jsono.getJSONObject("user");
company_id = jarray.getString("company_id");
branch_id = jarray.getString("branch_id");
Log.d("User Data", "company_id " + company_id + "\tbranch_id " + branch_id);
requestFinished = true;
} catch (JSONException e) {
e.printStackTrace();
}
}
And your getParams would look like :
protected Map<String, String> getParams() {
if(!requestFinished) return null;
Map<String, String> MyData = new HashMap<String, String>();
// BRANCH_ID AND COMPANY_ID ARE EQUAL NULL !?
MyData.put("branch_id", branch_id);
MyData.put("company_id", company_id);
Log.d("Last User Data", "company_id " + company_id + "\tbranch_id " + branch_id);
return MyData;
But I would suggest to you to use the Observer pattern instead.

Sorting data from Json array using android volley into activity

Im using volley to get and handle the Json object into the activity
and here are the classes and the following :
The problem is when im trying to get the Address ,Phones, Emails as sorting for each line from the object it show up like this first it get the address with the first line then it jumps to line 5 to get id then line 8 to get twitterUrl.
Inside the APP Data
web Service reponse on the postman
[
{
"address": "adddress1",
"emails": "ggggdjd#ttttt.com",
"facebookUrl": "ddddd",
"googlePlus": "ddddddd",
"id": 1,
"instagramUrl": "ddddd",
"phones": "0100098763 - 82726353",
"twitterUrl": "ddddd",
"youtubeUrl": "dddd"
