在Android中多次設置鬧鍾

Question

在我的應用程序中，我希望警報由用戶設置多次。 但是，如果我將鬧鍾設置為其他日期和時間，它只會在最后的設置時間響應。

例如，如果我為日期20-01-2017時間10.10 am ， 20-01-2017時間10.20 am ， 20-01-2017時間10.30 am設置了警報，依此類推，它僅給出最后一次選擇的日期和時間的警報。 但不會在20-01-2017時間10.10 am ， 20-01-2017時間10.20 am或其他選定時間發出警報。

如何在所有選定的時間得到警報？ 這是我的代碼：

public void setDate(View view) {
    DialogFragment newFragment = new DatePickerFragment();
    newFragment.show(getSupportFragmentManager(), "datePicker");
}

public void setTime(View view) {

    DialogFragment newFragment = new TimePickerFragment();
    newFragment.show(getSupportFragmentManager(), "timePicker");
}


public void setAlarm(View view) {
    Calendar calNow = Calendar.getInstance();
    Calendar calSet = (Calendar) calNow.clone();
    calSet.set(Calendar.HOUR_OF_DAY, alarmHour);
    calSet.set(Calendar.MINUTE, alarmMin);
    calSet.set(Calendar.DAY_OF_MONTH, alarmDay);
    calSet.set(Calendar.YEAR, alarmYear);
    calSet.set(Calendar.MONTH, alarmMonth);

    setAlarmN(calSet);
}

private void setAlarmN(Calendar targetCal) {

makeText(this, "Alarm is set at" + targetCal.getTime(),
        LENGTH_LONG).show();
Intent intent = new Intent(getBaseContext(), AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(
        getBaseContext(), RQS_1, intent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(),
        pendingIntent);


}

//date picker fragment
public static class DatePickerFragment extends DialogFragment
        implements DatePickerDialog.OnDateSetListener {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // Use the current date as the default date in the picker
        final Calendar c = Calendar.getInstance();
        int year = c.get(Calendar.YEAR);
        int month = c.get(Calendar.MONTH);
        int day = c.get(Calendar.DAY_OF_MONTH);

        // Create a new instance of DatePickerDialog and return it
        return new DatePickerDialog(getActivity(), this, year, month, day);
    }

    public void onDateSet(DatePicker view, int year, int month, int day) {
        // Do something with the date chosen by the user
        alarmDay = day;
        alarmYear = year;
        alarmMonth = month;
    }
}

//Time picker fragment
public static class TimePickerFragment extends DialogFragment
        implements TimePickerDialog.OnTimeSetListener {
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // Use the current time as the default values for the picker
        final Calendar c = Calendar.getInstance();
        int hour = c.get(Calendar.HOUR_OF_DAY);
        int minute = c.get(Calendar.MINUTE);

        // Create a new instance of TimePickerDialog and return it
        return new TimePickerDialog(getActivity(), this, hour, minute,
                DateFormat.is24HourFormat(getActivity()));
    }

    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
        // Do something with the time chosen by the user
        alarmHour = hourOfDay;
        alarmMin = minute;
    }
}

問題出在您的void setAlarmN()方法中。 您無法生成具有相同ID的警報通知。 那應該意味着通知被取消和覆蓋。 每次調用PendingIntent.getBroadcast()時，嘗試為RQS_1設置唯一的ID。 可能您必須聲明私有變量並對其進行遞增。
