Going thru this old post, noticed I have done something similar that might help:

public class FormatCursorAdapter extends SimpleCursorAdapter {

protected int[] mFormats;

public static final int FORMAT_TEXT=0;
public static final int FORMAT_CURRENCY=1;
public static final int FORMAT_DATE=2;

public FormatCursorAdapter(Context context, int layout, Cursor c, String[] from, int[] to, int[] formats, int flags) {
    super(context, layout, c, from, to, flags);
    mFormats = formats;
    ViewBinder viewBinder = new ViewBinder() {
        @Override
        public boolean setViewValue(View view, Cursor cursor, int columnIndex) {
            int formatType = mFormats[columnIndex-1];
            switch (formatType) {
                case FORMAT_CURRENCY:
                    NumberFormat nf = NumberFormat.getCurrencyInstance();
                    nf.setMaximumFractionDigits(2);
                    ((TextView)view).setText(nf.format(cursor.getDouble(columnIndex)));
                    return true;
                case FORMAT_DATE:
                    DateFormat df = SimpleDateFormat.getDateTimeInstance();
                    ((TextView)view).setText(df.format(new Date(cursor.getLong(columnIndex))));
                    return true;
            }
            return false;
        }
    };
    setViewBinder(viewBinder);
}

}

Usage:

    // For the cursor adapter, specify which columns go into which views with which format
    String[] fromColumns = {
            Table.COLUMN_TITLE,
            Table.COLUMN_AMOUNT,
            Table.COLUMN_DATE};
    int[] toViews = {
            R.id.tvTitle,
            R.id.tvAmount,
            R.id.tvDate};
    int[] formatViews = {
            FormatCursorAdapter.FORMAT_TEXT,
            FormatCursorAdapter.FORMAT_CURRENCY,
            FormatCursorAdapter.FORMAT_DATE};

    mAdapter=new FormatCursorAdapter(getContext(),R.layout.item_operation,cursor,
            fromOpsColumns,toOpsViews,formatViews,0);
    mListView.setAdapter(mOpsAdapter);

Hope this helps anyone out there !
