我想在特定日期通知通知.
然后我现在正在使用带有NotificationManager的AmarmManager.
当我从dateDialog设置所选日期时,警报正在运行.
如何在固定时间内将日历值设置在闹钟设置上？
我希望每天在固定时间重复闹钟,例如早上9点.
目前,警报忽略了特定日期的时间.
你可以帮帮我吗？非常感谢.

confirmButton.setOnClickListener(new View.OnClickListener() 
    {
        public void onClick(View v) {
            //set alarm with expiration date                
            am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
            setOneTimeAlarm();
            Toast.makeText(fridgeDetails.this, "Alarm automatic set", Toast.LENGTH_SHORT).show();
            setResult(RESULT_OK);
            finish();
        }
        public void setOneTimeAlarm() {
        c.set(Calendar.HOUR_OF_DAY, 10);
        c.set(Calendar.MINUTE, 0);
        c.set(expiredYear, expiredMonth, expiredDay);
        Intent myIntent = new Intent(fridgeDetails.this, AlarmService.class);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(fridgeDetails.this, 
                        0, myIntent, PendingIntent.FLAG_ONE_SHOT);
        am.set(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), pendingIntent);

        }
    });


private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() 
{
    public void onDateSet(DatePicker view, int year, int monthOfYear,
            int dayOfMonth) {
        expiredYear = year;
        expiredMonth = monthOfYear;
        expiredDay = dayOfMonth;
        displayDate();
    }
};  

public class AlarmService extends BroadcastReceiver{
NotificationManager nm;
@Override
public void onReceive(Context context, Intent intent) {
    nm = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);
          CharSequence from = "Check your fridge";
          CharSequence message = "It's time to eat!";
          PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
            new Intent(), 0);
          Notification notif = new Notification(R.drawable.ic_launcher,
            "Keep Fridge", System.currentTimeMillis());
          notif.setLatestEventInfo(context, from, message, contentIntent);
          nm.notify(1, notif);
         }  
}

解决方法:

您应该调用public void setRepeating(int type,long triggerAtTime,long interval,PendingIntent operation)(see here)来重复警报.例如,您想要在每天上午9:00触发警报,您​​可以执行以下操作：

Calendar c=Calendar.getInstance();
c.set(Calendar.HOUR_OF_DAY, 9);
c.set(Calendar.MINUTE, 0);
setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), AlarmManager.INTERVAL_DAY,pendingIntent);

此外,在初始化PendingIntent时将最后一个参数设置为0.

PendingIntent pendingIntent = PendingIntent.getBroadcast(fridgeDetails.this, 
                        0, myIntent, 0);
