我有一个场景
设置（周一至周五）警报
假设我选择的时间是：hour = 9, minutes = 15, am_pm = "AM"。
现在我想为每个Monday to Friday at 9:15 AM 设置警报
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();
}
我使用过类似于的BroadcastReceiver
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);
}
}
最终清单：
<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，我想告诉大家，One Time警报对我有效，但对于上述选择，Week Days (Mon-Fri)不能正确工作
工作代码为：
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。如有任何帮助，我们将不胜感激。
我假设警报只设置在周五9:15？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一个警报，当收到警报时，你就为第二天设置警报，以此类推。
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PendingIntent，这意味着它们的requestCode或backingIntent必须不同（具有不同的类型、操作或类别）。
试试这个代码，它对我有用…
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页面，并查看setRepeating（）中的注释。截至API 19，重复函数是不精确的。为了获得正确的重复，你必须每次处理警报并重新安排。
）首先，对于相同的挂起意图，不能有for循环，它将取消以前的实例。
)解决方案是在警报完成后，通过onReceive方法内的广播接收器再次设置警报。
)以下是如何实现这一点的想法，根据您的需求包括其余代码。我用日历课设置了闹钟，周五跳过两天。
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if-else条件下的"choice"，您可能必须将这些值存储在SharedPreferences之类的地方。
