ActionBarSherlock support library for Android

            ActionBarSherlock is an extension of the support library designed to facilitate the use of the action bar design pattern across all versions of Android with a single API.

           The library will automatically use the native action bar when appropriate or will automatically wrap a custom implementation around your layouts. This allows you to easily develop an application with an action bar for every version of Android from 2.x and up.

Define spinner used in activity by same id and arrayadapter for list the stored String in array

  final Spinner spinner = (Spinner) findViewById(R.id.spinner1);
  ArrayAdapter adapter = ArrayAdapter.createFromResource(
  this, R.array.countries, android.R.layout.simple_spinner_item);
  adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
  spinner.setAdapter(adapter);

 Spinnerdata.java

package com.pack.spinnerdata;

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

public class Spinnerdata extends Activity {

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_spinnerdata);
  
   //Write spinner and arrayAdapter for list the String stored in array 
  final Spinner spinner = (Spinner) findViewById(R.id.spinner1);
  ArrayAdapter adapter = ArrayAdapter.createFromResource(
  this, R.array.countries, android.R.layout.simple_spinner_item);
  adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
  spinner.setAdapter(adapter);
 }

 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  // Inflate the menu; this adds items to the action bar if it is present.
  getMenuInflater().inflate(R.menu.spinnerdata, menu);
  return true;
 }

}
