如何在android中以编程方式取消闹钟？ [复制]

我使用这段代码创建了一个警报并且它有效。请建议如何取消该警报。

Intent alarmIntent = new Intent(AlarmClock.ACTION_SET_ALARM);
            alarmIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            alarmIntent.putExtra(AlarmClock.EXTRA_MESSAGE, mEdtTitle.getText()
                    .toString());
            Calendar calendar = Calendar.getInstance();

            calendar.set(Calendar.HOUR, mTimePicker.getCurrentHour());
            calendar.set(Calendar.MINUTE, mTimePicker.getCurrentMinute());

            calendar.set(Calendar.DATE, mDatePicker.getDayOfMonth());
            calendar.set(Calendar.MONTH, mDatePicker.getMonth());
            calendar.set(Calendar.YEAR, mDatePicker.getYear());

            calendar.add(Calendar.MINUTE, 1);
            alarmIntent.putExtra(AlarmClock.EXTRA_HOUR,
                    calendar.get(Calendar.HOUR_OF_DAY));
            alarmIntent.putExtra(AlarmClock.EXTRA_MINUTES,
                    calendar.get(Calendar.MINUTE));
            alarmIntent.putExtra(AlarmClock.EXTRA_SKIP_UI, true);
startActivity(alarmIntent);

提前致谢

你需要使用该方法cancel(...) from AlarmManager，使用相同的PendingIntent你曾经设置过闹钟。例子：

this.getAlarmManager().cancel(mAlarmPendingIntent);（这是指您要从中取消警报的活动或服务）。

创建PendingIntent as:

mAlarmPendingIntent = PendingIntent.getActivity(this, requestCode, intent, flags);
