String choice1 =  "Select Your Choice";
 allNames.add(choice1);  


JSONArray array = jsonObject.getJSONArray("Spinner value");
                for (int i = 0; i < array.length(); i++) {
                    JSONObject job = array.getJSONObject(i);

Answer 2

Try this one, Before calling getting spinner data method, just add this line

String name="select your choice"
allNames.add(name);

then initialize getting spinner data form server

Answer 3

You can create your own object similar to the response received from server and add it to your list before parsing server data.

As here your server response is only string you can add a string object to your list.

allNames.clear();
allNames.add("Your First Option");//any string that relevance to your need
//code to parse server response
allNames.add(name);

Answer 4

Do this,

allNames.add("select your choice")

JSONArray array = jsonObject.getJSONArray("Spinner value");
for (int i = 0; i < array.length(); i++) {
JSONObject job = array.getJSONObject(i);
String name = job.getString("spinner_data");
allNames.add(name);}

It will automatically set first index as choice option.

Answer 5

  allNames.clear();
  allNames.add("Select Vehicle");
  JSONArray array = jsonObject.getJSONArray("Spinner value");
  for (int i = 0; i < array.length(); i++)
  {
  JSONObject job = array.getJSONObject(i);
  String name = job.getString("spinner_data");
  allNames.add(name);
  }

Answer 6

Try this

 JSONArray array = jsonObject.getJSONArray("Spinner value");
 allNames.add("Select Your Choice");    
 for (int i = 0; i < array.length(); i++) {
    JSONObject job = array.getJSONObject(i);
    String name = job.getString("spinner_data");
    allNames.add(name);

 }

 ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>
 (MainActivity.this, android.R.layout.simple_spinner_item, allNames);


 spinner.setAdapter(dataAdapter);

Answer 7

Add String -Select Your Choice- as the first element in the array List.

 String choice1 =  "-Select Your Choice-";
 allNames.add(choice1);     
 JSONArray array = jsonObject.getJSONArray("Spinner value");
                for (int i = 0; i < array.length(); i++) {
                    JSONObject job = array.getJSONObject(i);
                    String name = job.getString("spinner_data");
                    allNames.add(name);

                }

                ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>
                        (MainActivity.this, android.R.layout.simple_spinner_item, allNames);


                spinner.setAdapter(dataAdapter);
