            }
            // pass arrConuntry array to ArrayAdapter<String> constroctor :
            adapterallcities = new ArrayAdapter<String>(

            spinrcountry.setPrompt("Select City");
            spinrcountry.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
                @Override
                public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
                    cityspitems = spinrcountry.getSelectedItem().toString();
                    System.out.println("PresetEVent selected" + cityspitems);
                }

                @Override
                public void onNothingSelected(AdapterView<?> adapterView) {
                }
            });




        }
    }

Just you need add "Select Country" at first position of that array and length=response items + 1

    arrallcitiies = new String[citydata.size()+1];
    arrallcitiies[0]="Select Country"; //item at pos 0
    int j=1;
    for (int index = 0; index < citydata.size(); index++) {
    HashMap<String, String> map = citydata.get(index);
    arrallcitiies[j++] = map.get(CITY_NAME);
    }

    adapterallcities = new ArrayAdapter<String>(Registration.this,
                        android.R.layout.simple_spinner_dropdown_item, arrallcitiies);
    spinrcountry.setAdapter(adapterallcities);

You can edit

   // Making a request to url and getting response
            citydata = new ArrayList<HashMap<String, String>>();
            String jsonStr = sh.makeServiceCall(CITY_URL, ServiceHandler.GET);

to bellow:

// Making a request to url and getting response
            citydata = new ArrayList<HashMap<String, String>>();
            HashMap<String, String> map_select_country = new HashMap<String, String>();
            map_select_country.put("0","Select country");
            citydata.add(map_select_country); //add new this
            String jsonStr = sh.makeServiceCall(CITY_URL, ServiceHandler.GET);

try with this code

ArrayList<String> listcountry_id,listcountry;

listcountry_id=new ArrayList<String>();
listcountry=new ArrayList<String>();

 try {  
        JSONArray jarr=new JSONArray("your responce data here");

        for(int i=0;i<jarr.length();i++){

            JSONObject jobj=jarr.getJSONObject(i);
            listcountry_id.add(jobj.getString("country_id"));
            listcountry.add(jobj.getString("country"));              
        }       
    BindSpinnerData();      
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }       
}

 spnData.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> parent, View view,
                int position, long id) {
            // TODO Auto-generated method stub
            String ids = String.valueOf(position);
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub

        }
    });

private void BindSpinnerData() {
    // TODO Auto-generated method stub
    ArrayAdapter<String> spinnerLocation = new ArrayAdapter<String>(
            getApplicationContext(), R.layout.spinneritem, listcountry);
    spinnerLocation.setDropDownViewResource(R.layout.spinnerpopup);
    spnData.setAdapter(spinnerLocation); 
}

//spinneritem,spinnerpopup are textview layout there you can set color of text and background of colors

change below inside doInBackground()

HashMap<String, String> map = new HashMap<String, String>();

for (int i = 0; i < jsonObjcitys.length(); i++) {
    JSONObject c = jsonObjcitys.getJSONObject(i);
    // creating new HashMap

    // adding each child node to HashMap key => value
    //map.put(CITY_NAME, c.getString(CITY_NAME));

    map.put(CITY_NAME, c.getString(CITY_NAME));
    //  map.put(PRESET_TITLES, c.getString(PRESET_TITLES));
    citydata.add(map);

}
map.put("Select_City", "Select City");
citydata.add(map);

change below inside onPostExecute()
- After setting spinner adapter add below line.
```
spinrcountry.setSelection(adapter.getCount());
```

you'll have to create a custom adapter

public class HintAdapter extends ArrayAdapter < Objects > {


public HintAdapter(Context theContext, int theLayoutResId, String[] objects) {
    super(theContext, theLayoutResId, R.id.text1, objects);
}

@Override
public int getCount() {
    // don't display last item. It is used as hint.
    int count = super.getCount();
    return count > 0 ? count - 1 : count;
}
}

change setAdapter line in onPostExecute() to below-

adapterallcities = new HintAdapter(
            Registration.this,
            android.R.layout.simple_spinner_dropdown_item, arrallcitiies);

Above solution will display default "Select City" value and upon spinner selection it will only display list of City name and no default value.
