android - Changing values from Cursor using SimpleCursorAdapter

Question

I have database table with the columns {Name, Time (UTC format) , Latitude, Longitude}

I display the table using a ListActivity with a SimpleCursorAdapter.

I would like that the column Time show the time in a human readable format (13-07-2010 10:40) rather than in UTC format (18190109089).

How can I specify that the values from column Time need some filtering/adaptation?

POSSIBLE SOLUTION (with a problem):

SimpleCursorAdapter offers the method:

setCursorToStringConverter(SimpleCursorAdapter.CursorToStringConverter cursorToStringConverter);

to specify how a class that is able to convert a Cursor to CharSequence (convertToString(Cursor cursor). Anyway I don't know in which format should be the return CharSequence paramater!

The simplest way to format a cursor value is to use SimpleCursorAdapter.setViewBinder(..):

SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, R.layout.list, cursor,
            new String[] { Definition.Item.TITLE, Definition.Item.CREATE_DATE }, new int[] { R.id.title, R.id.createDate});

adapter.setViewBinder(new ViewBinder() {

    public boolean setViewValue(View aView, Cursor aCursor, int aColumnIndex) {

        if (aColumnIndex == 2) {
                String createDate = aCursor.getString(aColumnIndex);
                TextView textView = (TextView) aView;
                textView.setText("Create date: " + MyFormatterHelper.formatDate(getApplicationContext(), createDate));
                return true;
         }

         return false;
    }
});
