Question

这是我的代码。从那里我无法以编程方式生成警报..

    Calendar cal = Calendar.getInstance();
    int id = (int) cal.getTimeInMillis();
    Intent myIntent = new Intent(this,MyScheduledReceiver.class);
    myIntent.putExtra("taskTitle", taskTitle.getText().toString());
    myIntent.putExtra("taskDetails", taskDetails.getText().toString());

     cal.setTimeInMillis(System.currentTimeMillis());
     cal.set(year, mon, day,tp.getCurrentHour(),tp.getCurrentMinute());
    PendingIntent sender = PendingIntent.getBroadcast(getApplicationContext(), id,
            myIntent,PendingIntent.FLAG_UPDATE_CURRENT|  Intent.FILL_IN_DATA);
            AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
            am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), sender);

我在清单文件中声明了

<receiver android:name=".MyScheduledReceiver"></receiver>

广播接收器中的一个。

    NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
NotificationManager manger = (NotificationManager)     
context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.ic_launcher, "Combi Note",
 System.currentTimeMillis());
PendingIntent contentIntent = PendingIntent.getActivity(context, 
NOTIFICATION_ID, 
new Intent(context, MyScheduledReceiver.class), 0);
        Bundle extras=intent.getExtras();
        String title=extras.getString("taskTitle");
    String note=extras.getString("taskDetails");
        notification.setLatestEventInfo(context, note, title, contentIntent);
        notification.flags = Notification.FLAG_INSISTENT;
        notification.defaults |= Notification.DEFAULT_SOUND;
    manger.notify(NOTIFICATION_ID++, notification);

我有类似的东西并且有效。

首先你要声明一个Pending：

Intent intent = new Intent(Global.a, EventAlarmReceiver.class);
    intent.putExtra("title", ""+cd.title);
    intent.putExtra("desc", ""+cd.description);

    PendingIntent pendingIntent = PendingIntent.getBroadcast(
            Global.a.getApplicationContext(), (int) (cd.alarmTime), intent, PendingIntent.FLAG_CANCEL_CURRENT);

    AlarmManager alarmManager = (AlarmManager) Global.a.getSystemService(Activity.ALARM_SERVICE);
    alarmManager.set(AlarmManager.RTC, cd.alarmTime, pendingIntent);

在EventAlarmReceiver类中我有：

NotificationManager notificationManager = (NotificationManager) context.getSystemService(Activity.NOTIFICATION_SERVICE);

    String text = String.valueOf(intent1.getCharSequenceExtra("title"));

    Notification notification = new Notification(R.id.icon,
            text, System.getTimeInMillis());

    notification.vibrate = new long[]{100,250,300,330,390,420,500};

    // Hide the notification after its selected     
    notification.flags |= Notification.FLAG_AUTO_CANCEL;

    Intent intent = new Intent(context, ShowEventActivity.class);
    intent.putExtra("title", String.valueOf(intent1.getCharSequenceExtra("title")));
    intent.putExtra("desc", String.valueOf(intent1.getCharSequenceExtra("desc")));


    String text1 = String.valueOf(intent1.getCharSequenceExtra("desc"));

    PendingIntent activity = PendingIntent.getActivity(context, (int) System.getTimeInMillis() , intent, PendingIntent.FLAG_CANCEL_CURRENT);

    notification.setLatestEventInfo(context, text, text1, activity);

    notificationManager.notify((int)System.getTimeInMillis(), notification);

确保在Manifest中声明声明Receiver所在的包：例如在我的情况下，EventAlarmReceiver类是包com.app.name.notifications所以在清单中我有：

<receiver android:name=".notifications.EventAlarmReceiver"></receiver>

在android中生成带有通知问题的警报
