I have created simple example.

package com.android.loginactivity;

import com.android.loginactivity.R;

import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
import android.os.Bundle;
import android.preference.PreferenceManager;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TableLayout;
import android.widget.TableRow;
import android.widget.Toast;

public class Test extends Activity implements OnClickListener{

	EditText Email;
	EditText Password;
	Button login;

	
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		try {
			setContentView(R.layout.form);
			login = (Button) findViewById(R.id.btnLogin);
			Email = (EditText) findViewById(R.id.ETEmail);
			Password = (EditText) findViewById(R.id.ETPassword);
			login.setOnClickListener(this);
		} catch (Exception e) {
			e.printStackTrace();
		}

	}

	private void savePreferences(String key, String value) {
        
		SharedPreferences sp = PreferenceManager
				.getDefaultSharedPreferences(this);
		Editor edit = sp.edit();
		edit.putString(key, value);
		edit.commit();
	}

	
	@Override
	public void onClick(View v) {
		// TODO Auto-generated method stub
		savePreferences("NAME", Email.getText().toString());
		
		
		SharedPreferences sp = PreferenceManager
				.getDefaultSharedPreferences(this);
		
		String name = sp.getString("NAME", "YourName");
		Toast.makeText(this, name, Toast.LENGTH_LONG).show();
	}

	
	

}

how can i used this to save more than one value,as it saves key and values .E
Ex i need to ssave name,age,address..
i can save name in a one value pair .
