You need two things:
你需要两件事：
- AlarmManager: to schedule your notification at a regular bases (daily, weekly,..).
- Service: to launch your notification when the AlarmManager goes off.
- AlarmManager：定期（每天，每周，...）安排您的通知。
- 服务：在 AlarmManager 关闭时启动您的通知。
Here is a basic example:
这是一个基本示例：
In your Activity:
在您的活动中：
Intent myIntent = new Intent(this , NotifyService.class);
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
PendingIntent pendingIntent = PendingIntent.getService(this, 0, myIntent, 0);
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.SECOND, 0);
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.HOUR, 0);
calendar.set(Calendar.AM_PM, Calendar.AM);
calendar.add(Calendar.DAY_OF_MONTH, 1);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 1000*60*60*24 , pendingIntent);
This will trigger Alarm each day at midnight (12 am). You can change that if you want.
这将在每天午夜（上午 12 点）触发警报。如果你愿意，你可以改变它。
Now, create a Service NotifyServiceand put this code in its onCreate():
现在，创建一个服务NotifyService并将此代码放入其中onCreate()：
@Override
public void onCreate() {
NotificationManager mNM = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.notification_icon, "Notify Alarm strart", System.currentTimeMillis());
Intent myIntent = new Intent(this , MyActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, 0);
notification.setLatestEventInfo(this, "Notify label", "Notify text", contentIntent);
mNM.notify(NOTIFICATION, notification);
}
And this code will show the notification when the Alarm is received.
此代码将在收到警报时显示通知。
Good Luck!
祝你好运！

here is a little YouTube Video Tutorialabout daily notifications. You can find the source code in the description.
这是一个关于每日通知的YouTube 视频教程。您可以在说明中找到源代码。
This video is not made by myself. But I think its a quick help. Although i recommend some changes because the Notification.Builder is deprecated:
这个视频不是我自己做的。但我认为这是一个快速的帮助。虽然我建议进行一些更改，因为 Notification.Builder 已弃用：
1.
1.
import android.support.v4.app.NotificationCompat;
2.
2.
// Change: Notification mNotify = new Notification.Builder(this) to
Notification mNotify = new NotificationCompat.Builder(this)
Have Fun!
玩得开心！
