Spinners provide a way to select one value from a set. The spinner displays a dropdown menu with all available values, from which the user can select a new one. In the default state, a spinner shows its currently selected value.

 To add a list of values to the spinner, you then need to specify a SpinnerAdapter in your Activity, which extends Adapter class.. A spinner adapter allows to  define two different views: one that shows the data in the spinner itself and one that shows the data in the drop down list when the spinner is pressed.

 Here is a complete example that shows the usage of spinner.


<RelativeLayout xmlns:android=“http://schemas.android.com/apk/res/android”









        android:layout_height=“wrap_content” />



import android.os.Bundle;

import android.app.Activity;

import android.util.Log;

import android.view.Menu;

import android.view.View;

import android.widget.AdapterView;

import android.widget.ArrayAdapter;

import android.widget.Spinner;

import android.widget.AdapterView.OnItemSelectedListener;

public class MainActivity extends Activity {

       Spinner spin;

       String spin_val;

       String[] gender = { “Male”, “Female” };//array of strings used to populate the spinner


    public void onCreate(Bundle savedInstanceState) {


        setContentView(R.layout.activity_main);//setting layout

        spin = (Spinner) findViewById(R.id.spinner_id);//fetching view’s id

//Register a callback to be invoked when an item in this AdapterView has been selected

        spin.setOnItemSelectedListener(new OnItemSelectedListener() {


                     public void onItemSelected(AdapterView<?> arg0, View arg1,

                                  int position, long id) {

                           // TODO Auto-generated method stub

                           spin_val = gender[position];//saving the value selected



                     public void onNothingSelected(AdapterView<?> arg0) {

                           // TODO Auto-generated method stub



      //setting array adaptors to spinners

      //ArrayAdapter is a BaseAdapter that is backed by an array of arbitrary objects

        ArrayAdapter<String> spin_adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_spinner_item, gender);

      // setting adapter to spinner
