Question

I’ve an app that is retrieving a date that is stored as a string as a millisecs from 1970, eg 1324657734883.

I have a ListView that displays this date asis. I’d like to display the joda DateTime from this field in the database. My view displays the listview and populates it by using startManagingCursor() so i don’t think there is any way of converting the milisec format to a DateTime before it is populated to the listview.

Is there a way around this or do i have to store a DateTime and if so what is the column type i need to declare to store this type of data?

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    nfcscannerapplication = (NfcScannerApplication) getApplication();

    // setup UI
    setContentView(R.layout.viewtransactions);
    setTitle(getCarername() + " has completed " + nfcscannerapplication.loginValidate.getNumberOfTransactions() + " visits today");
    //transactionCount = (TextView)findViewById(R.id.textviewtransactionsfordaycount);
    viewTransactions = (ListView) findViewById(R.id.listviewtransactions);

    //transactionCount.setText("You have completed 6 transactions today");

    // get data
    cursor = nfcscannerapplication.loginValidate.queryAllFromTransactions();
    startManagingCursor(cursor);

    // setup adapter and show the data




    String[] from = { 
            LoginValidate.C_NAME, LoginValidate.C_TAG_SCAN_TIME,
            LoginValidate.C_TAG_SCAN_TIME};
    int[] to = { R.id.rowcarername, R.id.rowsignedinoutstatus, R.id.rowsenttoserverat };

    adapter = new SimpleCursorAdapter(nfcscannerapplication, R.layout.rowdataactual,
            cursor, from, to);
    viewTransactions.setAdapter(adapter);


}

}

        Cursor c = (Cursor)getItem(position);
        String val = c.getString(c.getColumnIndex(LoginValidate.C_TAG_SCAN_TIME));
        Date dt = new Date(Long.parseLong(val));
        SimpleDateFormat df = new SimpleDateFormat("dd MMMM yyyy");
        String res = df.format(dt);

        ((TextView)v.findViewById(R.id.rowsignedinoutstatus)).setText(res);
        ((TextView)v.findViewById(R.id.rowsenttoserverat)).setText(res);

        return v;
    }
}

}

Create a custom adapter that extends SimpleCursorAdapter:

class MyAdapter extends SimpleCursorAdapter {
    @Override
    View getView(int position, View convertView, ViewGroup parent) {
        View v = super.getView();
        if(v == null)
            return null;

        Cursor c = (Cursor)getItem(position);
        String val = c.getString(c.getColumnIndex(LoginValidate.C_TAG_SCAN_TIME));
        Date dt = new Date(Long.parseLong(val));
        SimpleDateFormat df = new SimpleDateFormat("dd MMMM yyyy");
        String res = df.format(val);

        ((TextView)v.findViewById(R.id.rowsignedinoutstatus)).setText(res);
        ((TextView)v.findViewById(R.id.rowsenttoserverat)).setText(res);

        return v;
    }
}

Then use it in place of the default one:

adapter = new MyAdapter(nfcscannerapplication, R.layout.rowdataactual, cursor, from, to);
