  confirmButton.setOnClickListener（新View.OnClickListener（）
    {
        公共无效的onClick（视图v）{
            //与到期日设定报警
            AM =（AlarmManager）getSystemService（Context.ALARM_SERVICE）;
            setOneTimeAlarm（）;
            Toast.makeText（fridgeDetails.this，报警自动设置，Toast.LENGTH_SHORT）.show（）;

        c.set（Calendar.HOUR_OF_DAY，10）;
        c.set（Calendar.MINUTE，0）;
        c.set（expiredYear，expiredMonth，expiredDay）;
        意图myIntent =新的意图（fridgeDetails.this，AlarmService.class）;
        PendingIntent pendingIntent = PendingIntent.getBroadcast（fridgeDetails.this，

        }
    }）;


私人DatePickerDialog.OnDateSetListener mDateSetListener =新DatePickerDialog.OnDateSetListener（）
{
    公共无效onDateSet（DatePicker的观点，年整型，诠释monthOfYear，
            INT DAYOFMONTH）{

          从CharSequence的=检查你的冰箱;
          CharSequence的消息=是时候吃的！
          PendingIntent contentIntent = PendingIntent.getActivity（上下文，0，

解决方案

您应该叫公共无效setRepeating（int型的，长triggerAtTime，间隔长，PendingIntent操作）（ 看到这里）重复报警。例如，你想天天火灾报警的上午9点，你可以这样做：

 日历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，initilazing的PendingIntent，当最后一个参数设置为0。

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

I wan to set alarm with notification at specific date.Then I am using AmarmManager with NotificationManager currently.When I set selected date from dateDialog, the alarm is working.How can I put calendar value on alarm set with fixed time?I want to repeat alarm every day on fixed time such as at 9:00 in the morning.Currently, alarm is ignoring the time on specific date.Could you help me? Many thanks.

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);
         }  
}

解决方案

You should call public void setRepeating (int type, long triggerAtTime, long interval, PendingIntent operation)(see here) to repeat the alarm. For example, you want to fire the alarm on 9:00 am every day, you can do :

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);

Also,set the last parameter to 0 when initilazing the PendingIntent.

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