Android的Google日历布局

Question

我的日历布局看起来是这样的：

A B C D E F G 

A B C D E F G 

A B C D E F G 

A B C D 

我想使该日历的第一天开始，例如，从第四元素的位置（本实施应仅适用于日历的第一行）是这样的：

blank A B C D 

A B C D E F 

A B C D E F 

A B C D E F 

我有一个GridView这一点，这是使用的RelativeLayout在这一个按钮，有作为背景另一个布局，不应该现在有关。

有什么建议吗？谢谢:)

Answer 1

在您通知您数据集更改之前，您可以使用此功能。

public void refreshDays() { 
     // clear items 
     items.clear(); 
     flagDepartureDate = false; 
     flagArrivalDate = false; 

     int lastDay = month.getActualMaximum(Calendar.DAY_OF_MONTH); 
     int firstDay = month.get(Calendar.DAY_OF_WEEK); 

     Calendar temp = (Calendar) month.clone(); 
     temp.add(Calendar.MONTH, -1); 

     Calendar temp2 = (Calendar) month.clone(); 
     temp2.add(Calendar.MONTH, +1); 

     int lastDay_prev = temp.getActualMaximum(Calendar.DAY_OF_MONTH); 

     /* 
     * if(((firstDay-1)+lastDay)>35) { 
     */ 
     calDay.days = new String[42]; 
     calDay.month = new int[42]; 
     calDay.year = new int[42]; 
     /* 
     * } else{ calDay.days = new String[35]; calDay.month = new int[35]; 
     * calDay.year = new int[35]; } 
     */ 

     // Log.i("LAST DAY", lastDay+""); 
     // Log.i("LAST DAY PREV", lastDay_prev+""); 
     // Log.i("FIRST DAY", firstDay+""); 
     // Log.i("FIRST_DAY_OF_WEEK", FIRST_DAY_OF_WEEK+""); 
     int start_blanks = 0; 
     int j = FIRST_DAY_OF_WEEK; 

     // populate empty days before first real day 
     if (firstDay > 1) { 
      for (j = 0; j < firstDay - FIRST_DAY_OF_WEEK - 1; j++) { 

       calDay.days[j] = "" 
         + (lastDay_prev - (firstDay - FIRST_DAY_OF_WEEK - 1) 
           + j + 1); 
       calDay.month[j] = temp.get(Calendar.MONTH); 
       calDay.year[j] = temp.get(Calendar.YEAR); 
       start_blanks += 1; 
      } 
     } else { 
      for (j = 0; j < FIRST_DAY_OF_WEEK * 6; j++) { 
       calDay.days[j] = ""; 
      } 
      j = FIRST_DAY_OF_WEEK * 6; // sunday => 1, monday => 7 
     } 
     // Log.i("START_BLANK", start_blanks+""); 
     // populate days 
     int dayNumber = 1; 
     for (int i = j; i < (lastDay + start_blanks); i++) { 
      calDay.days[i] = "" + dayNumber; 
      calDay.month[i] = month.get(Calendar.MONTH); 
      calDay.year[i] = month.get(Calendar.YEAR); 
      dayNumber++; 
     } 

     // populate empty days before first real day 
     for (int i = (lastDay + start_blanks), k = 1; i < calDay.days.length; i++, k++) { 
      calDay.days[i] = "" + k; 
      calDay.month[i] = temp2.get(Calendar.MONTH); 
      calDay.year[i] = temp2.get(Calendar.YEAR); 
     } 

    } 

这里的 “月” 为公历月的目标
