我有时间格式
2015-10-28T18:37:04.899 + 05:30
我必须以下面的格式创建广告位
11.00 AM - 12 PM 28/10/15
12.00 PM - 1 PM 28/10/15
1.00PM - 2.00PM 28/10/15
(local)
通过上面的代码我得到了输出
2015年1月28日星期三20:00:00 IST 2015
2015年1月28日星期三20:30:00 IST 2015
2015年1月28日星期三21:00:00 IST 2015
2015年1月28日星期三21:30:00 IST 2015
2015年1月28日星期三22:00:00 IST 2015
2015年1月28日星期三22:30:00 IST 2015
是24小时格式
我想要下面的格式
11.00 AM - 12 PM 28/10/15
12.00 PM - 1 PM 28/10/15
1.00PM - 2.00PM 28/10/15
任何人都可以帮我解决这个问题

我认为,这是你正在寻找的东西:
String timeValue = "2015-10-28T18:37:04.899+05:30";
SimpleDateFormat sdf= new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS");
try {
Calendar startCalendar = Calendar.getInstance();
startCalendar.setTime(sdf.parse(timeValue));
if (startCalendar.get(Calendar.MINUTE) < 30) {
startCalendar.set(Calendar.MINUTE, 30);
} else {
startCalendar.add(Calendar.MINUTE, 30); // overstep hour and clear minutes
startCalendar.clear(Calendar.MINUTE);
}
Calendar endCalendar = Calendar.getInstance();
endCalendar.setTime(startCalendar.getTime());
// if you want dates for whole next day, uncomment next line
//endCalendar.add(Calendar.DAY_OF_YEAR, 1);
endCalendar.add(Calendar.HOUR_OF_DAY, 24 - startCalendar.get(Calendar.HOUR_OF_DAY));
endCalendar.clear(Calendar.MINUTE);
endCalendar.clear(Calendar.SECOND);
endCalendar.clear(Calendar.MILLISECOND);
SimpleDateFormat slotTime = new SimpleDateFormat("hh:mma");
SimpleDateFormat slotDate = new SimpleDateFormat(", dd/MM/yy");
while (endCalendar.after(startCalendar)) {
String slotStartTime = slotTime.format(startCalendar.getTime());
String slotStartDate = slotDate.format(startCalendar.getTime());
startCalendar.add(Calendar.MINUTE, 30);
String slotEndTime = slotTime.format(startCalendar.getTime());
Log.d("DATE", slotStartTime + " - " + slotEndTime + slotStartDate);
}
} catch (ParseException e) {
// date in wrong format
}
我需要提一下,这段代码忽略了时区,但似乎你不需要它。示例输出:
cz.skywall.stack D/DATE: 07:00PM - 07:30PM, 28/10/15
cz.skywall.stack D/DATE: 07:30PM - 08:00PM, 28/10/15
cz.skywall.stack D/DATE: 08:00PM - 08:30PM, 28/10/15
cz.skywall.stack D/DATE: 08:30PM - 09:00PM, 28/10/15
cz.skywall.stack D/DATE: 09:00PM - 09:30PM, 28/10/15
cz.skywall.stack D/DATE: 09:30PM - 10:00PM, 28/10/15
cz.skywall.stack D/DATE: 10:00PM - 10:30PM, 28/10/15
cz.skywall.stack D/DATE: 10:30PM - 11:00PM, 28/10/15
cz.skywall.stack D/DATE: 11:00PM - 11:30PM, 28/10/15
cz.skywall.stack D/DATE: 11:30PM - 12:00AM, 28/10/15
正如我在代码中提到的,您可以通过取消注释第endCalendar.add(Calendar.DAY_OF_YEAR, 1);
行来为第二天生成广告位。

您可以使用以下内容,请注意,对于月份,您应使用MM
代替mm
。我添加了一个简单的getHoursValue
,因为我不了解你的。{/ p>
希望这有帮助!
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
displayTimeSlots();
}
private int getHoursValue(int hours){
return hours - 12;
}
private void displayTimeSlots(){
String timeValue = "2015-10-28T18:37:04.899+05:30";
StringTokenizer stringTokenizer = new StringTokenizer(timeValue,"T");
String dateValue = stringTokenizer.nextElement().toString();
String endDateValue = "2015-10-30";
String restString= stringTokenizer.nextElement().toString();
StringTokenizer secondTokeniser = new StringTokenizer(restString,":");
String hours = secondTokeniser.nextElement().toString();
String minutes = secondTokeniser.nextElement().toString();
hours = String.valueOf(Integer.parseInt(hours) + 2);
if (Integer.parseInt(minutes) > 30){
minutes = "00";
}else{
minutes = "30";
}
String amOrPm;
if(Integer.parseInt(hours) < 12){
amOrPm = "AM";
}else{
amOrPm = "PM";
hours = String.valueOf(getHoursValue(Integer.parseInt(hours)));
}
String time1 = hours + ":" + minutes + " " + amOrPm;
String time2 = "12" + ":" + "00" + " AM ";
String format = "yyyy-MM-dd hh:mm a";
SimpleDateFormat sdf = new SimpleDateFormat(format);
try {
Date dateObj1 = sdf.parse(dateValue + " " + time1);
Date dateObj2 = sdf.parse(endDateValue + " " + time2);
Log.d("TAG", "Date Start: " + dateObj1);
Log.d("TAG", "Date End: " + dateObj2);
long dif = dateObj1.getTime();
while (dif < dateObj2.getTime()) {
Date slot1 = new Date(dif);
dif += 3600000;
Date slot2 = new Date(dif);
dif += 3600000;
SimpleDateFormat sdf1 = new SimpleDateFormat("hh:mm a");
SimpleDateFormat sdf2 = new SimpleDateFormat("hh:mm a, dd/MM/yy");
Log.d("TAG", "Hour slot = " + sdf1.format(slot1) + " - " + sdf2.format(slot2));
}
}catch (ParseException ex){
ex.printStackTrace();
}
}
}
这是logcat:

你可以获得你的第一个时间间隔和类似的,你可以找到其他两个剩余的时间间隔。
String time ="2015-10-28T18:37:04.899+05:30";
try {
Date d= new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ").parse(time);
SimpleDateFormat dateFormat1=new SimpleDateFormat("hh:mm aaa dd/MM/yy");
String date =dateFormat1.format( d);
Calendar calendar = Calendar.getInstance();
calendar.setTime(dateFormat1.parse(date));
calendar.add(Calendar.HOUR, 1);
String one=dateFormat1.format(calendar.getTime());
String[] strings=date.split(" ");
one=(strings[0]+strings[1]+"-"+one);
System.out.println("Time here "+one);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
