Android 删除旧警报并使用警报管理器设置新警报

我与报警管理器有问题。我需要删除设置为特定时间的旧警报，并将警报重置为新时间。我尝试过很多场景，但没有一个适合我。非常感谢您的帮助。

在此处输入代码

//解除警报

    am = (AlarmManager)  getContext().getSystemService( ALARM_SERVICE);
    Intent i = new Intent( getContext(),AlarmReceiver.class);
    PendingIntent p = PendingIntent.getBroadcast( getContext(), profileFragmentRequestCode, i, 0);
    am.cancel(p);
    p.cancel();

//设置新警报

    am = (AlarmManager) getContext().getSystemService(ALARM_SERVICE);

       /* Retrieve a PendingIntent that will perform a broadcast */
    Intent alarmIntent = new Intent(getContext(), AlarmReceiver.class);

    PendingIntent pendingIntent = PendingIntent.getBroadcast(getContext(), profileFragmentRequestCode, alarmIntent,  0);
    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(System.currentTimeMillis());
    calendar.set(Calendar.HOUR_OF_DAY, 14);
    calendar.set(Calendar.MINUTE, 55);
    if (android.os.Build.VERSION.SDK_INT >= 19) {
        am.setExact(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
    } else {
        am.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
    }

确保您在

设置

和

取消

报警时使用了相同的

请求代码

设置报警：

AlarmManager alarmManager = (AlarmManager) getContext().getSystemService(Context.ALARM_SERVICE);

Intent alarmIntent = new Intent(getContext(), AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getContext(), REQUEST_CODE, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);

alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent)

AlarmManager alarmManager = (AlarmManager) getContext().getSystemService(Context.ALARM_SERVICE);

Intent alarmIntent = new Intent(getContext(), AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getContext(), REQUEST_CODE, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);

alarmManager.cancel(pendingIntent);

取消报警：

AlarmManager alarmManager = (AlarmManager) getContext().getSystemService(Context.ALARM_SERVICE);

Intent alarmIntent = new Intent(getContext(), AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getContext(), REQUEST_CODE, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);

alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent)

AlarmManager alarmManager = (AlarmManager) getContext().getSystemService(Context.ALARM_SERVICE);

Intent alarmIntent = new Intent(getContext(), AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getContext(), REQUEST_CODE, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);

alarmManager.cancel(pendingIntent);

@snachmsm是的，这是一个唯一的号码，我正在使用是的，我使用了相同的请求代码。我找到了解决方案calendar.set（calendar.HOUR\u OF_DAY，14）；日历。设置（日历。分钟，55）；上面这行代码造成了问题。。感谢您提供的解决方案。
