How to make notification appear only in top?

Question

So I have this code

public class notif extends Activity {
private static final int NOTIFY_ME_ID=1337;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
        final NotificationManager mgr=(NotificationManager)this.getSystemService(Context.NOTIFICATION_SERVICE);
        Notification note=new Notification(R.drawable.icon,"New Problem ",System.currentTimeMillis());
        note.flags|=Notification.FLAG_AUTO_CANCEL;
        PendingIntent i=PendingIntent.getActivity(this, 0,new Intent(this,list.class), 0);
        note.setLatestEventInfo(this,"Problem Occured","Click to see the problem",i);
        mgr.notify(NOTIFY_ME_ID,note);
}

This code is about making notifications but i want it to just appear on my notification on top an not opening any page at first so it's like the notification can appear in the main menu without opening any page at first like.the sms notification that appear on top only without having to see the entire sms until we click the notification so can someone help me with this? :)

Answer 1

    Create a class NotificationAlert and paste the code below there:

    import android.os.Bundle;
    import android.app.Activity;
    import android.app.Notification;
    import android.app.NotificationManager;
    import android.app.PendingIntent;
    import android.content.Context;
    import android.content.Intent;

    public class NotificationAlert extends Activity {

        private static final int NOTIFY_ME_ID=1337;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.notification_alert);

            /*********** Create notification ***********/

            final NotificationManager mgr=
                (NotificationManager)this.getSystemService(Context.NOTIFICATION_SERVICE);
            Notification note=new Notification(R.drawable.stat_notify_chat,
                                                            "Android Example Status message!",
                                                            System.currentTimeMillis());

            // This pending intent will open after notification click
            PendingIntent i=PendingIntent.getActivity(this, 0,
                                                    new Intent(this, NotifyMessage.class),
                                                    0);

            note.setLatestEventInfo(this, "Android Example Notification Title",
                                    "This is the android example notification message", i);

            //After uncomment this line you will see number of notification arrived
            //note.number=2;
            mgr.notify(NOTIFY_ME_ID, note);


        }
    }

Create a class NotifyMessage  and paste the code below there:

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class NotifyMessage extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        TextView txt=new TextView(this);

        txt.setText("Activity after click on notification");
        setContentView(txt);
    }
}

I think I know now that i have to use service and this is the code for making that service hope it helps other

public class servicenotif extends Service {
private static final String TAG = "servicenotif";
private static final int NOTIFY_ME_ID=1337;
private String url="Your URL";
SharedPreferences mPrefs;


@Override
public IBinder onBind(Intent intent) {
    // TODO Auto-generated method stub
    return null;
}
 @Override
    public void onCreate() {

     //Untuk bikin alarm yang ngecek ke database setiap 30 detik
        Log.d(TAG, "onCreate");
        Intent i = new Intent(this, servicenotif.class);
        PendingIntent pintent = PendingIntent.getService(this, 0, i,0);
        AlarmManager alarm = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
        alarm.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 30*1000, pintent);


    }
 @Override
    public void onStart(Intent intent, int startId) {
     //buat preference
     new LoginAsyncTask().execute();






    //Note: You can start a new thread and use it for long background processing from here.
    }
 class LoginAsyncTask extends AsyncTask<String, Integer, String> {
        String response = "";
        ProgressDialog dialog;
        //step2
        @Override
        protected String doInBackground(String... params) {

            // TODO Auto-generated method stub
            try {





                //publishProgress(190);


                mPrefs = getSharedPreferences("Preference", Context.MODE_PRIVATE);
                 //ngambil data preference
                 String txtTransID=mPrefs.getString("tid", "");
                 if(txtTransID.equals("")){
