The following should work for you:
以下应该对你有用：
Calendar cal = Calendar.getInstance();
cal.add(Calendar.DATE, -1);
System.out.println("Yesterday's date = "+ cal.getTime());
private String getYesterdayDateString() {
DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Calendar cal = Calendar.getInstance();
cal.add(Calendar.DATE, -1);
return dateFormat.format(cal.getTime());
}
