Just use a loop to generate a string array with the numbers, and add it to the spinner. — Raghav Sood, Feb 28 '13 at 12:13

You should create an adapter and then add items to the adapter.

You are beginner, I post full code

public class MainActivity extends Activity {

Spinner addnum_spinner;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    addnum_spinner=(Spinner) findViewById(R.id.spinner1);
    String[] myarray=new String[113];// create an array
    long a=600000;
    String v;
    for(int i=0;i<=113;i++)
    {
    v=String.valueOf(a);
    myarray[i]=v;
    a=a+1;
    }
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
    android.R.layout.simple_spinner_dropdown_item,myarray);
    addnum_spinner.setAdapter(adapter);
    }
}

ArrayAdapter.createFromResource we can't sent it argument in String – Gomathi Feb 28 '13 at 13:21
I didn't get you. Did you mean you can't pass String to ArrayAdapter.createFromResource ? `ArrayAdapter.createFromResource(this, R.array.str2, android.R.layout.simple_list_item_1);` Here str2 is string array. – Divya Motiwala Mar 01 '13 at 06:19

Make an array of values which you want to populate in the spinner like this:

      String []Pin = {"600000","600113"};

Inatialize, then bind it to the spinner like this:

      Spinner spinner = (Spinner) findViewById(R.id.YourSpinner); //From XML
      ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(this,     android.R.layout.simple_spinner_item, Pin);
      spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_list_item_1); // The drop down vieww
      YourSpinner.setAdapter(spinnerArrayAdapter);
      YourSpinner.setOnItemSelectedListener(this);

it's simpler:

long int start=600000;
String myarray[]=new String[113];
for(int i=0;i<=113;i++)
{
myarray[i++]=a+"";
a++;
}

and then

Spinner spinner = (Spinner) findViewById(R.id.spinner);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
myarray, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);

Spinner spinner = (Spinner) findViewById(R.id.spinner); ArrayAdapter adapter = ArrayAdapter.createFromResource(this, myarray, android.R.layout.simple_spinner_item); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner.setAdapter(adapter); – Gomathi Feb 28 '13 at 13:22
