How to setup setContentTitle and setContentText for Push Notification from json data

问题

I received the response from the server and I parsed that response in the android now I have to set the Notification Title and Text from that response. I means from that particular function.

Here I am putting my ParseList() function here where i parsed my response.

 private void parseList(Bundle bundle) {

        String id,name,photo,updates;

          try {
              JSONObject json = new JSONObject();
              Set<String> keys = bundle.keySet();
              for (String key : keys) {
                 try {
                     json.put(key, bundle.get(key)); 
                 } catch (JSONException e) {
                     e.printStackTrace();
                 }
              }

              JSONArray jsonarray = new JSONArray(json.getString("response"));
             Log.e("","Hi"+jsonarray);
              for (int i = 0; i < jsonarray.length(); i++) {
                  JSONObject jsonObjectmain = jsonarray .getJSONObject(i);

                  JSONArray array = jsonObjectmain.getJSONArray("updates");

                  for (int j = 0; j < array.length(); j++) {
                       JSONObject jsonObject = array.getJSONObject(j);
                         id = jsonObject.getString("id").toString();
                        name = jsonObject.getString("name").toString();
                        photo = jsonObject.getString("photo").toString();
                        updates = jsonObject.getString("updates").toString();

                  }      
              }
          } catch (Exception e) {
           e.printStackTrace();
          }
         }

There is a parameter called name,updates and photo. Now i have to setup the Notification Title from this response How can i set up that thing.. ?

I have onMessage() method with me but how can i put that values into that. ??

Here is my onMessage() method for Notification...

@Override
    protected void onMessage(Context context, Intent data) {

        String message; 

         message = data.getExtras().getString("name");


        Intent intent = new Intent(this, MyActivity.class);
        parseList(data.getExtras());

        PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent,
                PendingIntent.FLAG_UPDATE_CURRENT);

        Notification notification = new Notification.Builder(this)
                .setSmallIcon(R.drawable.ic_launcher)
                .setWhen(System.currentTimeMillis())
                .setContentTitle(message)
                .setContentText(message).setContentIntent(pIntent)
                .getNotification();

        notification.defaults |= Notification.DEFAULT_SOUND;
        notification.flags |= Notification.FLAG_AUTO_CANCEL;

        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        manager.notify(R.string.app_name, notification);

        {

            PowerManager pm = (PowerManager) context
                    .getSystemService(Context.POWER_SERVICE);
            final PowerManager.WakeLock mWakelock = pm.newWakeLock(
                    PowerManager.FULL_WAKE_LOCK
                            | PowerManager.ACQUIRE_CAUSES_WAKEUP, "GCM_PUSH");
            mWakelock.acquire();
            notification.defaults|=Notification.DEFAULT_VIBRATE;


            Timer timer = new Timer();
            TimerTask task = new TimerTask() {
                public void run() {
                    mWakelock.release();
                }
            };
            timer.schedule(task, 5000);
        }

    }

first your notification message must contains the values in different keys.

array( "title" => $title, "message" => $message )

the above code is php server side sample array data which is actually being added to 'data' key and then the data is sent to applications using the different servers. I have used GCM and while receiving data from server message get the above key data from bundle.

Notification notification = new Notification.Builder(this)
            .setSmallIcon(R.drawable.ic_launcher)
            .setWhen(System.currentTimeMillis())
            .setContentTitle(title)
            .setContentText(message).setContentIntent(pIntent)
            .getNotification();

here you can check that setContentTitle is used to add "title" and setContentText is the "subTitle" or message

You should use NotificationCompat.Builder to set the title, icon, content etc. for a notification. Here's an example:

private NotificationCompat.Builder mBuilder;
mBuilder = new NotificationCompat.Builder(
                    this).setSmallIcon(R.drawable.whitelogo)
                    .setLargeIcon(anImage)
                    .setContentTitle(title); //set smallIcon,largeIcon, contentTitle for your notification.

and to add the notification :

Notification.Builder notification = new Notification.Builder(this)
                          .setSmallIcon(R.drawable.ic_launcher)
                          .setWhen(System.currentTimeMillis())
                          .setContentTitle(message)
                          .setContentText(message)
                          .setContentIntent(pIntent); 

notificationManager.notify(NOTIFICATION_ID_NOTIF, notification.build());

UPDATE

It's not working in your case because, there's no String with key name in your bundle, so this will return null :

message = data.getExtras().getString("name");

so move your notification code in the parseList method, as there you have already extracted all the values (id,name,photo,updates).
