Here is something what we can use to add options to spinner2 w.r.t to spinner 1.

 

rea ;

  }

  }

  @Override

  public void onNothingSelected(AdapterView<?> arg0) {

   // TODO Auto-generated method stub

}

  });

  } // on-create

  @Override

  public void onClick(View v)

  {

  switch (v.getId())

  {

  case R.id.btnSubmit:

  break;

  case R.id.btnCancel:

finish();

  break;

  default:

  break;

  } 

} 

If you find this useful, then do give it up vote, so that others can find a good answer easily.

For each Country, you have to create a class for it, to just add State, City & Area. So that it doesn't

become a mesh at a single at single page.

Have fun.

Here is a sample code which depicts the usage of spinner and action performed when spinner item is

selected

import android.os.Bundle;

import android.app.Activity;

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 t

@Override

  public void onCreate(Bundle savedInstanceState) {

  super.onCreate(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

spin.setOnItemSelectedListener (new OnItemSelectedListener() {

  @Override

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

  int position, long id) { 

 // TODO Auto-generated method stub

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

  }

  @Override

  public void onNothingSelected(AdapterView<?> arg0) {

  TODO Auto- enerated method stub

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.You can

also download & refer to the complete spinner_demo example project for better understanding.
