import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.EditText;

public class BundleDataTransfer extends Activity {

      /** Called when the activity is first created. */

      EditText edtName, edtPhno;

      @Override

      public void onCreate(Bundle savedInstanceState) {

            super.onCreate(savedInstanceState);

            setContentView(R.layout.main);

            edtName = (EditText) findViewById(R.id.editText1);

            edtPhno = (EditText) findViewById(R.id.editText2);

            Button btnTransferData = (Button) findViewById(R.id.button1);

            btnTransferData.setOnClickListener(new OnClickListener() {

                  @Override

                  public void onClick(View v) {

                        // TODO Auto-generated method stub

                        String name = edtName.getText().toString();

                        double phno = Double.parseDouble(edtPhno.getText().toString());

                        Bundle bundle = new Bundle();

                        bundle.putString("name", name);

                        bundle.putDouble("phno", phno);

                        Intent intent = new Intent(getApplicationContext(),

                                    SecondScreen.class);

                        intent.putExtras(bundle);

                        startActivity(intent);

                  }

            });

      }

}

4)SecondScreenActivity:

import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.widget.TextView;

public class SecondScreen extends Activity {

      @Override

            super.onCreate(savedInstanceState);

            setContentView(R.layout.secondscreen);

            Intent intent = getIntent();

            Bundle bundle = intent.getExtras();

            String name = bundle.getString("name");

            Double phno = bundle.getDouble("phno");

            TextView tvName = (TextView) findViewById(R.id.textView3);

            TextView tvPhno = (TextView) findViewById(R.id.textView5);

            tvName.setText(name);
