我有一个场景

设置闹钟(周一到周五)

假设我选择的时间是:hour = 9, minutes = 15, am_pm = "AM"。

现在我想为每个星期一到星期五上午 9:15 设置闹钟

下面的代码我试过了，但没有得到想要的结果。

if(choice.equals("Week Days (Mon-Fri)"))
{
    for(int a = 2; a <= 5; a++) //here I am assuming a is from 2 to 5 (calendar DAY_OF_WEEK from Monday to Friday)
    {
        Calendar alarmCalendar = Calendar.getInstance();

        alarmCalendar.set(Calendar.HOUR_OF_DAY, _hourOfDay);

        alarmCalendar.set(Calendar.MINUTE, _minute);

        alarmCalendar.set(Calendar.SECOND, 0);

        alarmCalendar.set(Calendar.MILLISECOND, 0);

        if(am_pm.equals("AM"))
        {
            alarmCalendar.set(Calendar.AM_PM, 0);
        }
        else
        {
            alarmCalendar.set(Calendar.AM_PM, 1);
        }


        alarmCalendar.set(Calendar.DAY_OF_WEEK, a);

        Long alarmTime = alarmCalendar.getTimeInMillis();

        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, 
                alarmTime, 24 * 60 * 60 * 1000 , pendingIntent);
    }

    Toast.makeText(ActivityReminder.this, "Meeting Reminder Set on Week Days (Mon-Fri)", 
                        Toast.LENGTH_LONG).show();
}

我使用过 BroadcastReceiver，例如:

public class AlarmReceiver extends BroadcastReceiver
{
    NotificationManager mNotificationManager;

    Context context;

    public static final String TAG = "Reminder...";

    @Override
    public void onReceive(Context context, Intent intent)
    {
        this.context = context;

        String subject = "<h3>Meeting Reminder: </h3>" + intent.getStringExtra("subject");

        Toast.makeText(context, Html.fromHtml(subject), Toast.LENGTH_LONG).show();

        showNotification(subject);
    }

    @SuppressWarnings("deprecation")
    private void showNotification(String msg) 
    {
        Intent notificationIntent = new Intent(context.getApplicationContext(),
                ActivityMainScreen.class);

        TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);

        stackBuilder.addParentStack(ActivityMainGeofence.class);

        stackBuilder.addNextIntent(notificationIntent);

        String arrivalTime = TimeUtil.toString(Calendar.getInstance().getTime(), 
                "dd-MM-yyyy hh:mm:ss a");

        notificationIntent.putExtra("subject", msg)
        .putExtra("time", arrivalTime).putExtra("type", "Meetings/Reminder");

        PendingIntent notificationPendingIntent = stackBuilder
                .getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);

        Notification notification = new Notification();
        notification.icon = R.drawable.app_icon;

        notification.setLatestEventInfo(context.getApplicationContext(), 
                "WFM Meeting Reminder", Html.fromHtml(msg), notificationPendingIntent);

        notification.flags |= Notification.FLAG_AUTO_CANCEL;

        notification.defaults |= Notification.DEFAULT_SOUND;

        notification.defaults |= Notification.DEFAULT_VIBRATE;

        NotificationManager mNotificationManager = (NotificationManager) 
                context.getSystemService(Context.NOTIFICATION_SERVICE);

        mNotificationManager.notify(0, notification);

    }
}

最后在 list 中:

<receiver android:name="com.my_package_name.AlarmReceiver" >
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
</receiver>

已编辑: 在这里，我想说明 One Time 闹钟对我有用，但对于上述选择，Week Days (Mon-Fri) 无法正常工作

工作代码是:

if(choice.equals("One Time"))
{
    alarmManager.set(AlarmManager.RTC_WAKEUP, PERIOD, pendingIntent); // here PERIOD is the time selected by me in milliseconds...

    Toast.makeText(ActivityReminder.this, "Meeting Reminder Set One Time", 
            Toast.LENGTH_LONG).show();
}

我哪里做错了。任何帮助将不胜感激。

最佳答案

我会假设闹钟只设置在星期五的 9:15？这应该是因为 AlarmManager 文档中的以下行:

如果已经为同一个 IntentSender 安排了一个警报，它将首先被取消。 http://developer.android.com/reference/android/app/AlarmManager.html#setRepeating(int , 长, 长, android.app.PendingIntent)

为了做你想做的事，你要么需要 5 个 PendingIntents，要么只为第一个事件设置一个警报，当收到该警报时，你可以为第二天设置警报，依此类推。

我可能会选择第二个选项，因为在第一个方法中您需要 5 个不同的 PendingIntents，这意味着它们的 requestCode 或支持 Intent 必须不同(具有不同的类型、操作或类别)。
