How to create an Activity for a single?

Question

How do I rescue the sqlite data and send it to the xml single? My Sqliteopenhelper:

// Getting single
Contact getSingle(int id) {
SQLiteDatabase db = this.getReadableDatabase();

Cursor cursor = db.query(TABLE_SINGLE, new String[] { KEY_ID,
KEY_NAME, KEY_DESCRICAO}, KEY_ID + "=?",
new String[] { String.valueOf(id) }, null, null, null, null);
if (cursor != null)
cursor.moveToFirst();

Contact single = new Contact(Integer.parseInt(cursor.getString(0)),
cursor.getString(1), cursor.getString(2));

// return single
return single;

}
