    // TODO Auto-generated method stub
}

    // Print dates of the current week starting on Monday
    DateFormat df = new SimpleDateFormat("EEE dd/MM/yyyy");
    for (int i = 0; i < 14; i++) {
        dateStringArray.add(df.format(c.getTime()));

        c.add(Calendar.DATE, 1);

    }
    //adding additional option (remove) to the planner dialog 
    //dateStringArray.add("Remove");
    // Create a simple array adapter (of type string) with the test values
    weekadapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_list_item_single_choice,
            dateStringArray);

The Simplest way to obtain the Position of item from a ListView is as below.

 ListView.setOnItemClickListener(new OnItemClickListener() {

        @Override
       public void onItemClick(AdapterView<?> arg0, View arg1,
            int position, long arg3) {
        // TODO Auto-generated method stub
        String cn = -- YOUR ARRAY NAME---.get(position).toString();

        Intent intent = new Intent(this,---NEXT ACTIVITY--.class);

        intent.putExtra("cn", cn);
        startActivity(intent);
            }
        });

Put the code above in onCreate method of your activity.

It will fetch the string of item's position and lauch next activity and take selected position string ahead using intent
