How to count received Notifications in Android

Question

I am developing an app which will count received notifications in notification bar. Till now I am done with create multiple notifications on button click ans it is showing different notifications. What i want is it shows setText when single notification and when it is multiple it will count it n shows in setText.

I tried hard to find this on Stackoverflow and other Android sites but didnot find what i am looking for. Any help would be very support full.

If anyone is not able to understand my question then please let me know.

Here is the code:

Button noti;
int counter = 0;
boolean ncompi = false;
//  private static int pendingNotificationsCount = 0;

NotificationManager nManager;
NotificationCompat.Builder ncomp;

@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.imageclass);

SharedPreferences sharedpreferences = getSharedPreferences("MyPrefs", MODE_PRIVATE);
SharedPreferences.Editor editor = sharedpreferences.edit();
editor.putInt("count", count);
editor.putInt("counter", counter);
editor.commit();


SharedPreferences sharedPreferences = getSharedPreferences("MyPrefs", MODE_PRIVATE);
int i = sharedPreferences.getInt("count", 0);
int j = sharedPreferences.getInt("counter", 0);


  Button increaseButton = (Button) findViewById(R.id.btn1);
    increaseButton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub


            nManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
                ncomp = new NotificationCompat.Builder(ImageClass.this);
                ncomp.setContentTitle("9999900000");
                if(counter == 0){
                    ncomp.setContentText(ss);
                    counter++;
                   // ncomp.setContentText(ss);
                    Intent resultIntent = new Intent(ImageClass.this, MainActivity.class);

                //    resultIntent.putExtra("msg", ss);
                    PendingIntent pi = PendingIntent.getActivity(getApplicationContext(), 1, resultIntent, 0);

                    ncomp.setContentIntent(pi);
                    ncomp.setTicker("Notification Listener");
                    ncomp.setSmallIcon(R.drawable.ic_launcher);

                    ncomp.setAutoCancel(true);

                    nManager.notify(NOTIFY_ID, ncomp.build());
                }
                    else{
                         ncomp.setContentTitle("Notification");
                        ncomp.setContentText(counter + " Notifications");
                        Intent resultIntent = new Intent(ImageClass.this, SmsActivity.class);

                      //  resultIntent.putExtra("message", ss);
                        PendingIntent pi = PendingIntent.getActivity(getApplicationContext(), 1, resultIntent, 0);

                        ncomp.setContentIntent(pi);
                    ncomp.setTicker("Notification Listener");
                    ncomp.setSmallIcon(R.drawable.ic_launcher);
                    ncomp.setAutoCancel(true);
                    nManager.notify(NOTIFY_ID, ncomp.build());

                    counter++;
}

And also How to differ read and unread notifications in Notification Activity?

  ArrayList<MessageData> arrayList = new ArrayList<MessageData>();

    CustomListAdapter adapter = new CustomListAdapter(this, arrayList);
    smsListView.setAdapter(adapter);

    MessageData data1 = new MessageData();
    data1.setMessage("");
    data1.setRead(false);

Created CustomListAdapter n here is the code.

public class CustomListAdapter extends BaseAdapter {

private Context context;
private ArrayList<MessageData> dataList;

public CustomListAdapter(Context context, ArrayList<MessageData> arr){
      super();
        this.context = context;
        this.dataList = arr;
}

@Override
public int getCount() {
    // TODO Auto-generated method stub
     return dataList.size();
}

@Override
public Object getItem(int position) {
    // TODO Auto-generated method stub
    return dataList.get(position);
}

@Override
public long getItemId(int position) {
    // TODO Auto-generated method stub
    return position;
}


@Override
public View getView(int position, View view, ViewGroup arg2) {
    // TODO Auto-generated method stub
     if (view == null) {
            LayoutInflater inflater = (LayoutInflater) context
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            view = inflater.inflate(R.layout.listitem_spinner, null);

        }

        TextView textView = (TextView) view.findViewById(R.id.txt);

        textView.setText("" + dataList.get(position).getMessage());

        // here you can get Read/Unread status for all message
        boolean isRead = dataList.get(position).isRead();

        if (isRead) {
            textView.setTextColor(Color.GRAY);
        } else {
            textView.setTextColor(Color.BLACK);
        }

        return view;
}

}

You need to see Managing Notifications as it explains how to update notifications. Here is what you might want:

public variables

final int NOTIFY_ID=1; // any integer number
int count = 0;

on click event:

    NotificationManager nManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        NotificationCompat.Builder ncomp = new NotificationCompat.Builder(MainActivity.this);
        ncomp.setContentTitle("My Notification");
        if (count == 0)
            ncomp.setContentText("Notification");
        else
            ncomp.setContentText(count + " Notifications");
        Intent resultIntent = new Intent(MainActivity.this, Message.class);
        resultIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(MainActivity.this);
        stackBuilder.addNextIntent(resultIntent);
        PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
        ncomp.setContentIntent(resultPendingIntent);
        ncomp.setTicker("Notification Listener");
        ncomp.setSmallIcon(R.drawable.ic_launcher);
        ncomp.setAutoCancel(true);
        nManager.notify(NOTIFY_ID, ncomp.build());

        count++;

Hope this helped!

Edit: To store count refer Shared Preferences
