import android.app.Activity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.Spinner;

public class SpinnerUseInArea extends Activity {
	Spinner mySpinner;
	private static final String[] countriesStr = { "111", "222", "333", "444" };

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);

		mySpinner = (Spinner) findViewById(R.id.mySpinner);

		ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
				android.R.layout.simple_spinner_item, countriesStr);
		adapter.setDropDownViewResource(android.R.layout.simple_dropdown_item_1line);
		//adapter.setDropDownViewResource(R.layout.myspinner_dropdown);
		mySpinner.setAdapter(adapter);
