如何为特定的星期几设置重复通知？

Question

我正在寻找在工作日设置通知。我在警报对话框中添加了一串天来显示天数。

我想设置用户在警报对话框中选择的日历中的日期。此外，这应该在下周的同一天重复。

我已放置时间选择器对话框来选择通知时间。但是如果我这样做 c.getTime() ，那么我会得到当前的日期和时间。

如何设置其他日子的通知？就像今天是星期一，我想在星期三创建通知？如何在日历中设置星期三？

  c.set(Calendar.HOUR_OF_DAY, hour);
        c.set(Calendar.MINUTE, minute);
        c.set(Calendar.SECOND,0);
        c.set(Calendar.MILLISECOND,0);

        notification = c.getTime();
        notificationTime = df.format(notification);
        notifyTime.setText(notificationTime);
        Toast.makeText(getApplicationContext(),String.valueOf(notification),Toast.LENGTH_SHORT).show();

对于通知，我正在使用警报管理器。

 private void setAlarm(Calendar targetmCalen) {

    Intent intent = new Intent(getBaseContext(),NotificationReceiver.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), RQS_1, intent, 0);
    AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
    alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP,targetmCalen.getTimeInMillis(),
            AlarmManager.INTERVAL_DAY *7, pendingIntent);

    ComponentName receiver = new ComponentName(getApplicationContext(),NotificationReceiver.class);
    PackageManager pm = getApplicationContext().getPackageManager();

    pm.setComponentEnabledSetting(receiver,
            PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
            PackageManager.DONT_KILL_APP);

    Toast.makeText(getApplicationContext(),"Notification Set",Toast.LENGTH_SHORT).show();
}

选择日期的警报对话框：

  selectDay.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            final AlertDialog.Builder builder = new AlertDialog.Builder(AddEventActivity.this);

            builder.setSingleChoiceItems(R.array.day_array, -1,
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int item) {

                            String[] day = getBaseContext().getResources().getStringArray(R.array.day_array);

                            selectDay.setText(day[item]);

                            dialog.dismiss();
                        }
                    });
            builder.show();
        }
    });

我必须在警报对话框内的日历实例中设置 dayofweek 吗？喜欢

c.set(Calendar.DAY_OF_WEEK)?

编辑：

我试图这样做。但是如果我多次选择一天，这可能每次都会提前一天。

 selectDay.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            final AlertDialog.Builder builder = new AlertDialog.Builder(AddEventActivity.this);

            builder.setSingleChoiceItems(R.array.day_array, -1,
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int item) {

                            String[] day = getBaseContext().getResources().getStringArray(R.array.day_array);

                            selectDay.setText(day[item]);

                            dayOfWeek = day[item];

                            switch (dayOfWeek)
                            {
                                case  "Mon":
                                    c.set(Calendar.DAY_OF_WEEK,2);
                                    c.getTime();
                                    Toast.makeText(getApplicationContext(),String.valueOf(c.getTime()),Toast.LENGTH_SHORT).show();
                                    break;
                                case "Tue":

                                    c.set(Calendar.DAY_OF_WEEK, 3);
                                    c.getTime();
                                    Toast.makeText(getApplicationContext(),String.valueOf(c.getTime()),Toast.LENGTH_SHORT).show();
                                    break;
                                case "Wed":
                                    c.set(Calendar.DAY_OF_WEEK, 4);
                                    c.getTime();
                                    Toast.makeText(getApplicationContext(),String.valueOf(c.getTime()),Toast.LENGTH_SHORT).show();
                                    break;

                                case "Thu":
                                    c.set(Calendar.DAY_OF_WEEK, 5);
                                    c.getTime();
                                    Toast.makeText(getApplicationContext(),String.valueOf(c.getTime()),Toast.LENGTH_SHORT).show();
                                    break;

                                case "Fri":
                                    c.set(Calendar.DAY_OF_WEEK, 6);
                                    c.getTime();
                                    Toast.makeText(getApplicationContext(),String.valueOf(c.getTime()),Toast.LENGTH_SHORT).show();
                                    break;

                                case "Sat":
                                    c.set(Calendar.DAY_OF_WEEK, 7);
                                    c.getTime();

                                    break;

                                case "Sun":

                                    c.set(Calendar.DAY_OF_WEEK,1);

    });

请帮忙..

public class TimerReceiver extends BroadcastReceiver {

public  void scheduleAlarms(Context paramContext) {

    Calendar calendar = Calendar.getInstance();

    if (strmyTime.contains("One Week")) {
        calendar.set(Calendar.DATE, 7);

        registerReceiver(paramContext, calendar, AlarmManager.INTERVAL_DAY * 7);
    }

}

public  void registerReceiver(Context paramContext, Calendar calender, long interval) {

    AlarmManager localAlarmManager = (AlarmManager) paramContext.getSystemService(Context.ALARM_SERVICE);
    PendingIntent localPendingIntent = PendingIntent.getService(paramContext, 0,
            new Intent(paramContext, NotificationService.class), PendingIntent.FLAG_UPDATE_CURRENT);

    localAlarmManager.setRepeating(AlarmManager.RTC, calender.getTimeInMillis(), interval, localPendingIntent);

}

@Override
public void onReceive(Context context, Intent intent) {


    scheduleAlarms(context);
    context.startService(new Intent(context, Notification.class));
        }

}

我希望你已经解决了你的问题。但我仍然会发布我的解决方案。所以如果有人绊倒。

private void sendNotification(){
    Intent notificationIntent = new Intent(HomeActivity.this, NotificationReceiver.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(),
            NOTIFICATION_REQUEST_CODE,
            notificationIntent,
            PendingIntent.FLAG_UPDATE_CURRENT);
    AlarmManager alarmManager = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);
    Calendar calendar = Calendar.getInstance();
    calendar.set(Calendar.HOUR_OF_DAY, CONST.NOTIFICATION_TIME_HOUR);
    calendar.set(Calendar.MINUTE, 0);
    for (int i = 1; i < 8; ++i){
        if (i != 6){
            calendar.set(Calendar.DAY_OF_WEEK, i);
            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), CONST.NOTIFICATION_INTERVAL, pendingIntent);
        }
    }
}

这里long NOTIFICATION_INTERVAL = 7 * 24 * 60 * 60 * 1000; & int NOTIFICATION_TIME_HOUR = 9;
