如何自定义日历以仅打印当前日期行？

Question

如何只打印那个有当前日期的行？下面是我的代码，它使用2维数组并打印文本视图中的所有值我想过滤该数组并只显示具有当前月份日期的数组我将如何做？下面是函数CalculateCalendar（），它在Hoyahcalencer类对象a中设置数组值 HoyahCalendar.a [i / 7] [i％7]我如何只打印那个当前有效的行我也在下面用cpaste完整代码进行参考

  public void CalculateCalendar(int month_no, int week_no, int month_days){

    int i, s;
    //String[][] a = new String[6][7];
    for (i=0;i<week_no;i++)
        HoyahCalendar.a[i/7][i%7] = "";

    for(i=week_no; i<week_no + month_days; i++){
        s = i - week_no + 1;
        HoyahCalendar.a[i/7][i%7] = String.valueOf(s);
    }
    for(i=week_no+month_days; i<42; i++)


        HoyahCalendar.a[i/7][i%7] = "";
}
  }
