为了这效果肝了几天，调了几天，改了几天，头都晕了！

在 ViewBinder 里设置背景

adapter.setViewBinder(new SimpleCursorAdapter.ViewBinder(){
    public boolean setViewValue(View view, Cursor cursor, int columnIndex){               
        if (view.getId() == R.id.textView_count) {
            Date date = new Date(cursor.getLong(columnIndex));
            Date date1 = new Date();
                long ms = date.getTime() - date1.getTime();
                long d = ms / 1000 / 60 / 60 / 24;
                if (ms >= 0)
                    view.setBackgroundColor(0xff00bfff);
                else
                    view.setBackgroundColor(0xffffa500);
                ((TextView)view).setText(Math.abs(d) + "");
                return true;
            } else if (view.getId() == R.id.textView_day) {
                Date date = new Date(cursor.getLong(columnIndex));
                Date date1 = new Date();
                long ms = date.getTime() - date1.getTime();
                if (ms >= 0)
                    view.setBackgroundResource(R.drawable.day_bg);
                else
                    view.setBackgroundResource(R.drawable.day_bg1);
                return true;
            }
            return false;
        }
});
