How to repeat notification daily on specific time in android through background service
提问by user3458918
Hi I am working on application where I have set the notification on user entered date and time through background service. Now I want to set notification/alarm daily at 6 pm to ask user does he want to add another entry? How can I achieve this? Should I use the same background service or Broadcast receiver? Please give me better solution for that and tutorial will be great idea. Thanks in advance.
嗨，我正在开发应用程序，我通过后台服务设置了用户输入日期和时间的通知。现在我想每天下午 6 点设置通知/闹钟，询问用户是否要添加另一个条目？我怎样才能做到这一点？我应该使用相同的后台服务还是广播接收器？请给我更好的解决方案，教程将是个好主意。提前致谢。

First set the Alarm Manager as below
首先设置报警管理器如下
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);
Create an Broadcast Receiver Class "AlarmReceiver" in this raise the notifications when onReceive
在此创建一个广播接收器类“AlarmReceiver”，在 onReceive 时引发通知
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++;
}
}
and in the manifest file, register receiver for the AlarmReceiver class:
并在清单文件中，为 AlarmReceiver 类注册接收器：
<receiver android:name=".AlarmReceiver"/>
No special permissions are required to raise events via alarm manager.
通过警报管理器引发事件不需要特殊权限。

N.V.Rao's answer is correct, but don't forget to put the receivertag inside the application tag in the AndroidManifest.xml file:
NVRao 的回答是正确的，但不要忘记将receiver标签放在 AndroidManifest.xml 文件中的应用程序标签内：
<receiver android:name=".alarm.AlarmReceiver" />
