        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);

//I fetched the data from my database

        DBase db = new DBase(this);
        db.open();
        String recs = db.getAllRecords();
        db.close();
        if (recs.isEmpty()) {
            Toast.makeText(this, "No records found.", Toast.LENGTH_SHORT)
                    .show();
        } else {
