我有 sqlite 数据库表，它与朋友及其联系人的出生日期联系。我想在数据库中的任何日期与当前日期匹配时发出警报。请任何人帮助我如何完成这项任务。实际上我想每天匹配日期 2 次，请建议我。

我正在使用此代码

private void setAlarm(String name,String date)
{
    String[] arrdob =date.split("/");
    Calendar cal = Calendar.getInstance();       //for using this you need to import java.util.Calendar;

    // add minutes to the calendar object
    cal.set(Calendar.MONTH,Integer.parseInt(arrdob[1]));
    cal.set(Calendar.YEAR, Integer.parseInt(arrdob[2]));                
    cal.set(Calendar.DAY_OF_MONTH,Integer.parseInt(arrdob[0]));
    cal.set(Calendar.HOUR_OF_DAY,14);
    cal.set(Calendar.MINUTE,35);
    System.out.println("1");

    Intent alarmintent = new Intent(getApplicationContext(), AlarmReceiver.class);
    alarmintent.putExtra("title","B'Day Alarm");
    alarmintent.putExtra("subject","Hi!Todays "+name+" B'Day");

    PendingIntent sender = PendingIntent.getBroadcast(getApplicationContext(), HELLO_ID,
    alarmintent,PendingIntent.FLAG_UPDATE_CURRENT |  Intent.FILL_IN_DATA);
    //VERY IMPORTANT TO SET FLAG_UPDATE_CURRENT... this will send correct extra's informations to 
    //AlarmReceiver Class
   // Get the AlarmManager service               
    AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
    am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), sender);
}

在将值插入数据库时​​调用此方法。AlarmReceiver 类如下：

private static int NOTIFICATION_ID = 1;

@Override
public void onReceive(Context context, Intent intent) //
{
    // NotificationManager mNotificationManager = 
    System.out.println("2");
   //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, AlarmReceiver.class), 0);

    Bundle extras=intent.getExtras();
    String title=extras.getString("title");
 //here we get the title and description of our Notification
    String note=extras.getString("subject");
    notification.setLatestEventInfo(context, note, title, contentIntent);
    notification.flags = Notification.FLAG_INSISTENT;
    notification.defaults |= Notification.DEFAULT_SOUND;

//这里我们为 //notification 设置默认声音

    // The PendingIntent to launch our activity if the user selects this notification
    manger.notify(NOTIFICATION_ID++, notification);
}
