My AlarmManagerReceiver :

 DatabaseHelper mDatabaseHelper;
    ArrayList   listData = new ArrayList<>();
    ArrayList   listDataoran = new ArrayList<>();
    ArrayList   listDataBoya = new ArrayList<>();
    ArrayList   listDataId = new ArrayList<>();
    ArrayList   listDatanumber = new ArrayList<>();
Random secilmiskisi ;
int secilmissayı;


   @Override
    public void onReceive(Context context, Intent intent) {
        mDatabaseHelper = new DatabaseHelper(context);
        Cursor data = mDatabaseHelper.getData();
        while(data.moveToNext()){

            listDataId.add(data.getString(0));

            listData.add(data.getString(1));


            listDatanumber.add(data.getString(2));

            listDataoran.add(data.getString(3));
            listDataBoya.add(data.getString(4));}

 secilmiskisi = new Random();
        secilmissayı = secilmiskisi.nextInt(listDataId.size()) + 0;

I want to change my notification text when selected number"s line (random number)is green.

Have you read the documentation related to changing a notification https://developer.android.com/training/notify-user/managing.html ? — Adinia, Aug 18 '17 at 10:01

    String subtext[]={"text one","text two","text three","text four"......};


    int ran=new Random().nextInt(4);

android.app.Notification notif = new android.app.Notification.Builder(getApplicationContext())
                .setContentTitle("M-Educate welcomes you the Digital era of learning")
                .setSubText(subtext[ran])
                .setSmallIcon(R.drawable.icn_app_icon)
                .setLargeIcon(icon)

        NotificationManager notificationManager = (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(0, notif);

Note : set your texts as in a array and set the random text each time you fire notification

It doesn"t work.My problem is while loop doesn"t working when line become green.It doesn"t show the text.. — Hatay Berkay Işıkoğlu, Aug 18 '17 at 09:57

Try this code, replacing your existing one:

        mDatabaseHelper = new DatabaseHelper(context);
        Cursor data = mDatabaseHelper.getData();
        while(data.moveToNext()){

        listDataId.add(data.getString(0));

        listData.add(data.getString(1));


        listDatanumber.add(data.getString(2));

        listDataoran.add(data.getString(3));
        listDataBoya.add(data.getString(4));}

//        secilmiskisi = new Random();

You have declared the random number globally, so it won't change throughout the process.

Sorry I don"t understand what do you mean with Place the random thing in local.And I copied your code to my broadcastreceiver.It still doesn"t show me while loop. — Hatay Berkay Işıkoğlu, Aug 18 '17 at 17:16
I have refresh your code. Did you mean that ? Because it doesn"t work.İf i do wrong.Just say I am begginner at broadcastReceiver. — Hatay Berkay Işıkoğlu, Aug 18 '17 at 17:32

How can I change my notification text?
