如何处理多个通知？

Question

根据通知编写应用程序，通知将数据写入SQLite。例如，将名称和日期作为字符串并使用AlarmManager DatePicker。但是，当我设置06.03和09.03的通知时，它只会在06.03收到通知。如何做到支持多个通知，如06和09？

public class Rachunki extends AppCompatActivity {
EditText name, surname;
Button btnAdd;
ListView lst;
DbCon dbcon;
DbCon.DbHelper dbHelper;
AlarmManager alarmManager;
DatePicker datePicker;

Button alarmON,okbtn;
EditText editprice,editname;
String minute_string;
String hour_string;

//public  EditText editName,editPrice ;



private PendingIntent pending_intent;

private TimePicker alarmTimePicker;
private static Rachunki inst;
private TextView alarmTextView;
int richard_quote = 0;
private AlarmReceiver alarm;
private Context context;


String year_string, month_string,day_string,date;

     final Intent myIntent = new Intent(this.context, AlarmReceiver.class);

    dbcon=new DbCon(this);

            try {
                dbcon.insertS(name.getText().toString(), surname.getText().toString(),date.toString());
               loadR();
            } catch (Exception e) {

            }
        }
    });

         alarmON.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                calendar.set(Calendar.YEAR,datePicker.getYear());

                calendar.set(Calendar.MONTH,datePicker.getMonth());
                calendar.set(Calendar.DAY_OF_MONTH,datePicker.getDayOfMonth());

                final int year = datePicker.getYear();
                final int month = datePicker.getMonth();
                final int day = datePicker.getDayOfMonth();

                year_string= String.valueOf(year);
                month_string= String.valueOf(month);
                day_string = String.valueOf(day);

                if (month < 10) {
                   month_string= "0" + String.valueOf(month);
               }
                if ( day<10){
                 day_string="0"+String.valueOf(day);
               }
                date = day_strin

                   myIntent.putExtra("extra", "yes");
                    myIntent.putExtra("quote id", String.valueOf(richard_quote));
                    pending_intent = PendingIntent.getBroadcast(Rachunki.this, 0, myIntent, PendingIntent.FLAG_UPDATE_CURRENT);
                    alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pending_intent);

                    setAlarmText(date );}
                }
            });




    }
