android 字符串 时间格式化 Android 获取年月日时分秒 格式化指定时间字符串

1、获取Android系统当前时间年月日 时分秒(24小时制)

//获取当前时间

Time time=new Time();

time.setToNow();

Log.i("cp","year="+time.year+" month="+(time.month+1)+" day="+time.monthDay+" hour="+time.hour+" minute="+time.minute);

注意获取到的月份是从0-11，所以要 +1

2、格式化指定的时间字符串

pushDate = format.parse("-12-21 05:49:00");

calendar=Calendar.getInstance();

calendar.setTime(pushDate);

Log.i("cp", "year="+calendar.get(Calendar.YEAR)+" month="+(calendar.get(Calendar.MONTH)+1)+

" day="+calendar.get(Calendar.DAY_OF_MONTH)+ "hour= "+calendar.get(Calendar.HOUR)+" minute= "+calendar.get(Calendar.MINUTE));

Log.i("cp", "year="+calendar.get(Calendar.YEAR)+" month="+(calendar.get(Calendar.MONTH)+1)+

" day="+calendar.get(Calendar.DAY_OF_MONTH)+ "hour= "+calendar.get(Calendar.HOUR_OF_DAY)+" minute= "+calendar.get(Calendar.MINUTE));

同样注意获取到的月份是从0-11，所以要 +1

Calendar.HOUR

获取到的是12小时制

Calendar.HOUR_OF_DAY 获取到的是24小时制
