AlarmManager和接收器Android Studio Java多次通知

Question

我设置了两个不同的警报，应发出2个通知

8：34：0 pm创建通知1带标题和味精..

8:34:10 pm创建通知2带标题和味精...

问题是他们俩在晚上8:34:00一起出现 (在第一个警报时间(两者((！！！

我做了什么： -

1-我与通知管理器一起举办了一个广播课以构建通知

2-主要活动创建了AlarmManager和日历实例，以设置Alarm的时间。

    public class MainActivity extends AppCompatActivity {

        @RequiresApi(api = Build.VERSION_CODES.KITKAT)
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    // Creating alarm method(requestcode,hours,min,seconds)
            setAlarmo(1,20,34,0);
            setAlarmo(2,20,34,10);
        }
    // the Alarm Method
        public void setAlarmo(int reqcode, int hour,int minute,int second){

            Calendar calendar = Calendar.getInstance();
            calendar.set(Calendar.HOUR_OF_DAY,hour);
            calendar.set(Calendar.MINUTE,minute);
            calendar.set(Calendar.SECOND,second);
            long timeinMillis = calendar.getTimeInMillis();
            Intent intent = new Intent(getApplicationContext(),AlertRec.class);
            intent.putExtra("reqcode",reqcode);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(),reqcode,intent,PendingIntent.FLAG_ONE_SHOT);
            AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
            alarmManager.set(alarmManager.RTC_WAKEUP,timeinMillis,pendingIntent);
        }
    }

// AlertClass receiver extending broadcastReceiver
    public class AlertRec extends BroadcastReceiver {
        @Override
        public void onReceive( final Context context, Intent intent) {
// Creating receiveAlarm method(requestCode,Context,intent,title,text for notification)
//receiving first Alarm from MainActivity.Class 
         recAlarmo(1, context,intent,"title 1","im msg 1");

//receiving Second Alarm from MainActivity.Class     
         recAlarmo(2,context,intent,"title 2","im msg 2");
    }

    // receiving Alarms Method and Creating Notifications
    public void recAlarmo(int reqcode , Context context,Intent intent,String title,String msg){

     intent = new Intent(context,MainActivity.class);
     NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
     PendingIntent pendingIntent = PendingIntent.getActivity(context.getApplicationContext(),reqcode,intent,PendingIntent.FLAG_ONE_SHOT);
     builder.setContentTitle(title);
     builder.setSmallIcon(android.R.drawable.star_on);
     builder.setContentText(msg);
     builder.setAutoCancel(true);
     builder.setContentIntent(pendingIntent);
     builder.setDefaults(NotificationCompat.DEFAULT_SOUND);
     NotificationManager nm = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
     nm.notify(reqcode,builder.build());
    }
    }

Answer 1

    i solved it !
    ------------------------------
    in MainActivity 
    1-create a method that takes int number
    and inside the method make a pending intent and within the intent of the pending intent
     pass the int number as intent.putExtra("id",number);
public void Method(int id ,int hour , int minute, int seconds){
 Calendar calendar = Calendar.getInstance();
            calendar.set(Calendar.HOUR_OF_DAY,hour);
            calendar.set(Calendar.MINUTE,minute);
            calendar.set(Calendar.SECOND,second);
 Intent alertIntent = new Intent(getApplicationContext(), AlertRec.class);
            alertIntent.putExtra("id",id);
                AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
                alarmManager.set(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis(),PendingIntent.getBroadcast(getApplicationContext(),id,alertIntent,PendingIntent.FLAG_UPDATE_CURRENT));
}
    ----------------------------------------------------
    2- at the Receiver class 

    //override the OnReceive method
    onReceive(Context context,Intent intent ){
     int Checker =intent.getExtras.getInt("id");
             if(Checker == 1 ) {
                 // do anything you want for the intent of the pending intent at MainActivity that have int id  = 1;
            //your method here
             }else if(Checker == 2) {
                 // do anything you want for the intent of the pending intent at MainActivity that have int id  = 2;
            // your method here
             }else{
    }
    }
