public class MainActivity extends Activity implements AdapterView.OnItemSelectedListener

{

       String[] country = { "India", "USA", "China", "Japan", "Other", };

       @Override

       protected void onCreate(Bundle savedInstanceState)

       {

              super.onCreate(savedInstanceState);

              setContentView(R.layout.activity_main);

             

              Spinner spin = (Spinner) findViewById(R.id.spinner1);

              spin.setOnItemSelectedListener(this);

              ArrayAdapter aa = new ArrayAdapter(this,android.R.layout.simple_spinner_item, country);

              aa.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
