Reformatting date before displaying through SimpleCursorAdapter

I have a GridView that I populate from my SQLite Database through SimpleCursorAdapter as follows

public void Paygrid() {
    final Account Acc = (Account) getIntent().getSerializableExtra("FromDetails");
    dbHelper = new DatabaseHelper(this);
    String Payment = String.valueOf(Acc._id);
    Cursor a = dbHelper.FilterPayments(Payment);
    startManagingCursor(a);

    String[] from = new String[]{DatabaseHelper.colPayBal, DatabaseHelper.colInterest, DatabaseHelper.colPayDue, DatabaseHelper.colDateDue, DatabaseHelper.colPayDate};
    int[] to = new int[]{R.id.Amount, R.id.Interest, R.id.Total, R.id.DateDue, R.id.Paid};

    SimpleCursorAdapter saa = new SimpleCursorAdapter(this, R.layout.paygrid, a, from, to);
    intgrid.setAdapter(saa);
}

This works fine but because I have date comparison queries so I store my dates as "yyyy-MM-dd" but what I want to show is "MMM-dd-yyyy".

I already know how to do this but my problem is I don't know how to do this before my SimpleCursorAdapter starts populating my GridView.

This is what I was hoping to use before my SimpleCursorAdapter starts populating the GridView:

try {
    DateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    Date input = inputFormat.parse(date);
    DateFormat outputFormat = new SimpleDateFormat(" MMM-dd-yyyy ", Locale.ENGLISH);
    String finaldate = outputFormat.format(input);
    txtDate.setText(finaldate);
} catch (Exception ex) {
    Alerts.CatchError(AccountDetails.this, ex.toString());
}
