You can try this

@Override
public void onItemClick(AdapterView<?> parent, View   view, int position,
        long id) {
    RowItem selItem =  rowItems.get(position);//get the selected RowItem from the list
    String[] selValues= selItem.getMethodName();//your method name in RowItem.java class
                                                //which returns array  
    //if you have getter and setters you can access them and put them in array
    //String[] selArray = new String[size];//size = number of value you want to supply
    //String[0]= selItem.getTitle();//for title
    //String[1] = selItem.getDescription();//for description and so on
    //then send the array as parameter 

    // remaining is same as answered by the Jay Gajjar

    Bundle b=new Bundle();
    b.putStringArray("EXTRA", selArray);
    Intent i = new Intent(getApplicationContext(), ShoppingCart.class);
    i.putExtras(b);
    startActivity(i);
}

and to retrieve the values in the ShoppingCart class

Bundle b=this.getIntent().getExtras();
String[] array=b.getStringArray("EXTRA");

get the selected item of list view and send the value via intent

@Override
public void onItemClick(AdapterView<?> parent, View   view, int position,
        long id) {
String value = lv1.getItemAtPosition(position).toString();
Intent i = new Intent(getApplicationContext(), ShoppingCart.class);
i.putExtra("EXTRA", value);
    startActivity(i);
}

and get the value in other activity

Bundle bundle=getIntent().getExtras();
String value=bundle.getString("EXTRA");

You need to create a singleton array of the menu items. When user performs multi select jst store the selectedindex to an array and then pass that array to the intent.

Here is the tutorial for multi-select listview

http://www.vogella.com/articles/AndroidListView/article.html

Here is the code to send array in intent

Bundle b=new Bundle();
b.putStringArray(key, new String[]{value1, value2});
Intent i=new Intent(context, Class);
i.putExtras(b);

Bundle b=this.getIntent().getExtras();
String[] array=b.getStringArray(key);

You can use a very simple Class which will store your data into it. I warn you that this class is just a simple proposition how to solve your problem. It has many weaknesses but it works ; ) You can improve it : ) Just init it at Application Class.

Here is example:

/**
 * Manager to handle passing data between Activities
 * 
 * @author Klawikowski
 * 
 */
public class ManagerBundle implements IConstants
{
    public static final String TAG = "ManagerBundle";

    private static Hashtable< Integer , Object > sDataTable;

    public static void init()
    {
        Log.i( TAG , "[ManagerBundle] Initializing ..." );
        sDataTable = new Hashtable< Integer , Object >();
    }

    public static void addBundle( int pKey , Object pObjectToPass )
    {
        Log.i( TAG , "[ManagerBundle] Adding Object to Manager using key: " + pKey );
        sDataTable.put( pKey , pObjectToPass );
    }

    public static Object getBundle( int pKey )
    {
        Log.i( TAG , "[ManagerBundle] Getting Object from Manager using key: " + pKey );
        Object lData = sDataTable.get( pKey );
        sDataTable.remove( pKey );
        return lData;
    }
}

Just simply put an Table / Array or any other container before starting Activity, and collect it from 2nd one ; )
