Calendar cal1 = getCalendarFromDate(mStartDate);long startTime = cal1.getTimeInMillis();Calendar cal2 = getCalendarFromDate(mEndDate);long endTime = cal2.getTimeInMillis();int numberOfDays = (int)(endTime - startTime)/(24 * 60 * 60 * 1000);/*** @param date format is 2012-9-18* @return Calendar value is after set date's value*/private Calendar getCalendarFromDate(final String date) { int year = 0; int month = 0; int day = 0; try { String[] array = date.split("-"); int[] arrayInt = new int[array.length]; for (int i = 0; i < array.length; i++) { arrayInt[i] = Integer.parseInt(array[i]); if(i == 0) { year = arrayInt[0]; } else if(i == 1){ month = arrayInt[1]; } else if(i == 2){ day = arrayInt[2]; } } } catch (Exception e) { e.printStackTrace(); } Calendar cal = Calendar.getInstance(); if(year > 0 && month >= 0 && day >= 0) { cal.set(year, month, day); } return cal;} |
PS:month 取值范围为0-11
希望本文所述对大家Android程序设计有所帮助。
