Hi I am working on application where I have set the notification on user entered date and time through background service.

推荐答案

首先如下设置报警管理器

First set the Alarm Manager as below

 Calendar calendar = Calendar.getInstance();
 calendar.set(Calendar.HOUR_OF_DAY, 18);
 calendar.set(Calendar.MINUTE, 30);
 calendar.set(Calendar.SECOND, 0);
 Intent intent1 = new Intent(MainActivity.this, AlarmReceiver.class);
 PendingIntent pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0,intent1, PendingIntent.FLAG_UPDATE_CURRENT);
 AlarmManager am = (AlarmManager) MainActivity.this.getSystemService(MainActivity.this.ALARM_SERVICE);
 am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);

在此创建一个广播接收器类AlarmReceiver"接收时通知

Create an Broadcast Receiver Class "AlarmReceiver" in this raise the notifications when onReceive

public class AlarmReceiver extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub

        long when = System.currentTimeMillis();
        NotificationManager notificationManager = (NotificationManager) context
                .getSystemService(Context.NOTIFICATION_SERVICE);

        Intent notificationIntent = new Intent(context, EVentsPerform.class);
        notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

        PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
                notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);


        Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        NotificationCompat.Builder mNotifyBuilder = new NotificationCompat.Builder(
                context).setSmallIcon(R.drawable.applogo)
                .setContentTitle("Alarm Fired")
                .setContentText("Events to be Performed").setSound(alarmSound)
                .setAutoCancel(true).setWhen(when)
                .setContentIntent(pendingIntent)
                .setVibrate(new long[]{1000, 1000, 1000, 1000, 1000});
        notificationManager.notify(MID, mNotifyBuilder.build());
        MID++;

    }

}

在清单文件中，为 AlarmReceiver 类注册接收器:

and in the manifest file, register receiver for the AlarmReceiver class:

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

通过警报管理器引发事件不需要特殊权限.

No special permissions are required to raise events via alarm manager.
