java - Android 日历布局

Question

我的日历布局如下所示:

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

我想让日历的第一天开始，例如，从第四个元素的位置开始(此实现应该仅适用于日历的第一行)，如下所示:

 blank A B C D

A B C D E F

A B C D E F

A B C D E F

我为此有一个 GridView，它使用一个带有 Button 的relativelayout，该按钮具有另一个布局作为背景，但现在不应该相关。

有什么建议吗...？谢谢:)

在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”是当前日历月的对象
