Android alarm class

I have a class which sets an alarm but I need to set around 10 more of these alarms. Instead of duplicating classes, is there a way I can just make a new instance of the class and set the alarm time?

Here's my code.

  import java.util.Calendar;

import java.lang.String;

import android.app.Activity;
import android.app.AlarmManager;
import android.app.ListActivity;
import android.app.PendingIntent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;

import android.content.Intent;
import android.widget.Button;
import android.widget.Toast;


public class Alarm extends Activity {
    /* for logging - see my tutorial on debuggin Android apps for more detail */
    private static final String TAG = "SomeApp "; 
    protected Toast mToast; 

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main); 


    setAlarm();
    }





   public void setAlarm() {


        try {   

        Calendar cal = Calendar.getInstance();

        cal.add(Calendar.DAY_OF_YEAR, 0);
        cal.set(Calendar.HOUR_OF_DAY, 9);
        cal.set(Calendar.MINUTE, 01);
        cal.set(Calendar.SECOND, 0);


        Intent intent        = new Intent(Alarm.this, Alarm1.class);
        PendingIntent sender = PendingIntent.getBroadcast(this, 1234567, intent, 0);
        PendingIntent sende2 = PendingIntent.getBroadcast(this, 123123, intent, 0);

        AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
        am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), sender); // to be alerted 30 seconds from now
        am.set(AlarmMa开发者_如何学Pythonnager.RTC_WAKEUP, cal.getTimeInMillis(), sende2); // to be alerted 15 seconds from now

        /* To show how alarms are cancelled we will create a new        Intent and a new PendingIntent with the
        * same requestCode as the PendingIntent alarm we want to cancel. In this case, it is 1234567.
            * Note: The intent and PendingIntent have to be the same as the ones used to create the alarms.
            */
        Intent intent1        = new Intent(Alarm.this, Alarm1.class);
        PendingIntent sender1 = PendingIntent.getBroadcast(this, 1234567, intent1, 0);
        AlarmManager am1 = (AlarmManager) getSystemService(ALARM_SERVICE);
        am1.cancel(sender1);


        } catch (Exception e) {
            Log.e(TAG, "ERROR IN CODE:"+e.toString());
        }
    }

};





    b1.setOnClickListener(new View.OnClickListener() {
                    public void onClick(View v) {


                    //  Intent i = new Intent(getContext(),Alarm.class);



//Code below is from another class which is where im calling the alarm application



                       // ctx.startActivity (i);// start the Alarm class activity (class)public void onClick(View v) {

                        Alarm a = new Alarm ();

                        a.setAlarm();


                        b1.setText(prod);


                    }
                });

The above code is from another class and on the button click the user can set a reminder (the buttom invokes the alarm class, the only to get it to work is using an intent. I simply tried to call the setAlarm method but that didn't work. Maybe I could make a new instance of calendar and set the time in the button handler. Then I would have to pass that instance to the alarm class. Do you know if that would be possible?

Can't you just create one Calendar instance in onCreate(), set its parameters, then pass the instance to setAlarm(), modify the instance, call setAlarm(), etc, or am I missing something?

e.g. -

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main); 

    Calendar cal = Calendar.getInstance();

    cal.add(Calendar.DAY_OF_YEAR, 0);
    cal.set(Calendar.HOUR_OF_DAY, 9);
    cal.set(Calendar.MINUTE, 01);
    cal.set(Calendar.SECOND, 0);
    setAlarm(cal);

    cal.set(Calendar.HOUR_OF_DAY, 12);
    cal.set(Calendar.MINUTE, 30);
    setAlarm(cal);

//etc

}

public void setAlarm(Calendar cal) {

    try {   

    Intent intent        = new Intent(Alarm.this, Alarm1.class);
    PendingIntent sender = PendingIntent.getBroadcast(this, 1234567, intent, 0);
    PendingIntent sende2 = PendingIntent.getBroadcast(this, 123123, intent, 0);

    AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
    am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), sender); // to be alerted 30 seconds from now
    am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), sende2); // to be alerted 15 seconds from now

    /* To show how alarms are cancelled we will create a new        Intent and a new PendingIntent with the
    * same requestCode as the PendingIntent alarm we want to cancel. In this case, it is 1234567.
        * Note: The intent and PendingIntent have to be the same as the ones used to create the alarms.
        */
    Intent intent1        = new Intent(Alarm.this, Alarm1.class);
    PendingIntent sender1 = PendingIntent.getBroadcast(this, 1234567, intent1, 0);
    AlarmManager am1 = (AlarmManager) getSystemService(ALARM_SERVICE);
    am1.cancel(sender1);


    } catch (Exception e) {
        Log.e(TAG, "ERROR IN CODE:"+e.toString());
    }
}

You can only have one activity in the foreground so to call setAlarm 10 times you would need to go an alternative route. Maybe loop? ;)
