我有一个场景
为（星期一至星期五）设置闹钟
假设我选择时间：hour = 9, minutes = 15, am_pm = "AM"。
现在我想为每Monday to Friday at 9:15 AM
下面的代码我试过但没有得到理想的结果。
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BroadcastReceiver之类的：
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Manifest中：
<receiver android:name="com.my_package_name.AlarmReceiver" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
编辑：
在这里，我想告诉One Time警报对我有效，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();
}
我在哪里做错了。任何帮助将不胜感激。

我会假设警报只在周五9:15设定？这应该是因为AlarmManager文档中的以下行：
If there is already an alarm scheduled for the same IntentSender, it will first be canceled.
http://developer.android.com/reference/android/app/AlarmManager.html#setRepeating(int，long，long，android.app.PendingIntent）
为了做你想做的事，你要么想要5个PendingIntents，要么只为第一个事件设置闹钟，当收到那个闹钟时，你设置第二天的闹钟，依此类推。
我可能会使用第二个选项，因为在第一个方法中你需要5个不同的PendingIntents，这意味着它们的requestCode或后备Intent必须是不同的（具有不同的类型，动作或类别）。

试试这段代码对我有用......
for (int k = 2; k < 5; k++) {
int sday = k;
Calendar today = Calendar.getInstance();
Calendar AlarmDate = Calendar.getInstance();
AlarmDate.set(Calendar.HOUR_OF_DAY, inputH);
AlarmDate.set(Calendar.MINUTE, inputM);
AlarmDate.set(Calendar.SECOND, 0);
while (today.after(AlarmDate)) {
AlarmDate.add(Calendar.DAY_OF_MONTH, 1);
}
while (AlarmDate.get(Calendar.DAY_OF_WEEK) != sday) {
AlarmDate.add(Calendar.DAY_OF_MONTH, 1);
}
Intent i = new Intent(this, AlertPopUpActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
i.putExtra("uid", k + (alert.getId() * 1000)); //a unique id for alram
i.putExtra("id", alert.getId());
i.putExtra("msg", alert.getEventName());
if (minute < 10)
i.putExtra("time", hour + ":0" + minute);
else
i.putExtra("time", hour + ":" + minute);
i.putExtra("ampm", inputAMPM);
PendingIntent pi = PendingIntent.getActivity(this,
k + (alert.getId() * 1000), i, //same unique id (used to update alram if canceled)
PendingIntent.FLAG_UPDATE_CURRENT);
am.set(AlarmManager.RTC_WAKEUP, AlarmDate.getTimeInMillis(), pi);
System.out.println("Set Time :" + AlarmDate.getTime());
}

查看AlarmManager的页面，然后查看setRepeating（）中的注释。从API 19开始，重复函数是不精确的。为了获得正确的重复，你必须每次都处理警报并重新安排它。
答案 3 :(得分：2)
）首先，你不能为相同的待定意图进行循环，它将取消之前的实例。
）解决方案是在完成报警后通过onReceive方法中的广播接收器再次设置闹钟。
）以下是如何实现这一点的想法，根据您的要求包含其余代码。我使用日历类来设置闹钟，并在周五跳过2天。
void setAlarm() {
AlarmManager alarmManager = (AlarmManager) context
.getSystemService(Context.ALARM_SERVICE);
if (choice.equals("One Time")) {
alarmManager.set(AlarmManager.RTC_WAKEUP, PERIOD, pendingIntent);
Toast.makeText(context, "Meeting Reminder Set One Time",
Toast.LENGTH_LONG).show();
} else if (choice.equals("Week Days (Mon-Fri)")) {
Calendar calendar = Calendar.getInstance();
int day = calendar.get(Calendar.DAY_OF_WEEK);
switch (day) {
case Calendar.MONDAY:
alarmManager
.set(AlarmManager.RTC_WAKEUP, PERIOD, pendingIntent);
case Calendar.TUESDAY:
alarmManager
.set(AlarmManager.RTC_WAKEUP, PERIOD, pendingIntent);
case Calendar.WEDNESDAY:
alarmManager
.set(AlarmManager.RTC_WAKEUP, PERIOD, pendingIntent);
case Calendar.THURSDAY:
alarmManager
.set(AlarmManager.RTC_WAKEUP, PERIOD, pendingIntent);
case Calendar.FRIDAY:
alarmManager.set(AlarmManager.RTC_WAKEUP, PERIOD * 3,
pendingIntent);
}
}
}
）对于＆＃34;选择＆＃34;在if-else条件下，您可能必须将这些值存储在SharedPreferences之类的某个位置。
