addToStart Func not working

[takawww]

Hi all

I can add new message by using addToStart only in my first time init MessagesList Activity
After I close it and reopen the activity again, addToStart is no longer function.

Any hints?

Best Regards

Are you still having this problem?
Can you log out any required info and paste them?

It's pretty straight-forward though.

Message message = new Message.Builder(Message.MessageType.TYPE_TEXT, Utilities.createMessageID())
                .user(SmartAlumni.currentUser)
                .message(message_string)
                .room(roomID)
                .build();
messagesAdapter.addToStart(message, true);

Hi,

I still have the issue whenever I re-open the activity which contain the MessagesList object
I init the activity by

Activity activity = (Activity) mContext
Intent activityChangeIntent = new Intent(activity, MsgBoxActivity.class);
activity.startActivity(activityChangeIntent);

In the activity, i have created a global observer to refresh the message list view by calling loadMessages and triggered by global timer.

protected void loadMessages() {
        new Handler().postDelayed(new Runnable() { //imitation of internet connection
            @Override
            public void run() {
                ArrayList<Message> messages = new ArrayList<>();
                for (int i = 0; i < MainActivity.msgboxObjs.size(); i++) {
                    if (MainActivity.msgboxObjs.get(i).respID.equals(LoginActivity.pollMan.selMsgGpID)) {
                        MsgBoxObj msgBoxObj = MainActivity.msgboxObjs.get(i);
                        MessageObj messageObj = LoginActivity.pollMan.selMsgGp;

                        if (!isFirst){
                            if (!msgBoxObj.isNew){
                                continue;
                            }
                        }

                        msgBoxObj.isNew = false;
                        Message message;
                        message = getMessage(messageObj, msgBoxObj);
                        messages.add(message);
                    }
                }

                Collections.sort(messages, new Comparator<Message>() {
                    @Override
                    public int compare(Message o1, Message o2) {
                        if (o1.getCreatedAt().after(o2.getCreatedAt())){
                            return -1;
                        }else{
                            return 1;
                        }

                    }
                });

                if (isFirst){
                    isFirst = false;
                    if (messages.size() > 0){
                        messagesAdapter.addToEnd(messages, false);
                    }
                }else{
                    for (int i=0;i<messages.size();i++){
                        messagesAdapter.addToStart(messages.get(i), true);
                  
                    }
                }





            }


        }, 1000);


    }

getMessage is function to create message object from my custom message object

public static Message getMessage(MessageObj messageObj, MsgBoxObj msgObj) {
        SimpleDateFormat format = new SimpleDateFormat("yyyyMMddHHmmss");
        Date dtCreateDate;

        if (msgObj.msgType.equals("O")){
            if (msgObj.msg.length() > 5){
                if (msgObj.msg.substring(0,5).equals("ATTA:")){
                    String url = LoginActivity.sysPath + "/" + LoginActivity.sysApp + "/upload/msg/" + messageObj.respID + "/" + msgObj.msg.substring(5);

                    User user = new User("0", messageObj.ownerName, messageObj.ownerImg, true);
                    Message message = new Message(msgObj.msgID, user, null);
                    try{
                        message.setImage(new Message.Image(url));
                    }catch (Exception ex){
                        ex.printStackTrace();
                    }

                    try {
                        dtCreateDate = format.parse(msgObj.createDate + msgObj.createTime);
                        message.setCreatedAt(dtCreateDate);
                    }catch (Exception ex){

                    }

                    return message;
                }else{

Hi,

The problem is temporary fixed

I have narrowed down the issue, which that it is happened inside global observer receive function.

private BroadcastReceiver msgBoxListViewRefreshReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            for (int i = 0; i < MainActivity.msgboxObjs.size(); i++) {
                if (MainActivity.msgboxObjs.get(i).respID.equals(LoginActivity.pollMan.selMsgGpID)) {
                    MsgBoxObj msgBoxObj = MainActivity.msgboxObjs.get(i);
                    MessageObj messageObj = LoginActivity.pollMan.selMsgGp;

                    if (! msgBoxObj.isNew) {
                        msgBoxObj.isNew = false;
                        
                        Message message;
                        message = getMessage(messageObj, msgBoxObj);
                        messagesAdapter.addToStart(message, true);
                    }
                }
            }
        }
    };

If i set a condition if(!msgObj.isNew){....addToStart(...) },
During my 2nd time to init the Activity, when global observer receive function is triggered,
addToStart can be fired, but no new message is shown in the messageList.

Now that I have change the condition to if (msgObj.createDate > lastMsgDate){...addToStart(...)},

private BroadcastReceiver msgBoxListViewRefreshReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            for (int i = 0; i < MainActivity.msgboxObjs.size(); i++) {
                if (MainActivity.msgboxObjs.get(i).respID.equals(LoginActivity.pollMan.selMsgGpID)) {
                    MsgBoxObj msgBoxObj = MainActivity.msgboxObjs.get(i);
                    MessageObj messageObj = LoginActivity.pollMan.selMsgGp;

                    if (Integer.parseInt(msgBoxObj.createDate) > Integer.parseInt(lastShownDate)) {
                        msgBoxObj.isNew = false;
                        lastShownDate = msgBoxObj.createDate;
                        lastShownTime = msgBoxObj.createTime;

                        Message message;
                        message = getMessage(messageObj, msgBoxObj);
                        messagesAdapter.addToStart(message, true);
                    }else{
                        if (Integer.parseInt(msgBoxObj.createDate) == Integer.parseInt(lastShownDate)) {
                            if (Integer.parseInt(msgBoxObj.createTime) > Integer.parseInt(lastShownTime)) {
                                msgBoxObj.isNew = false;
                                lastShownDate = msgBoxObj.createDate;
                                lastShownTime = msgBoxObj.createTime;

                                Message message;
                                message = getMessage(messageObj, msgBoxObj);
                                messagesAdapter.addToStart(message, true);
                            }
                        }
                    }
                }
            }
        }
    };

it is work!!!

Problem is so weird. and I have no conclusion of the root cause
but at least I can continue my work.

Please Someone help me how to add data in Dialog Please.

[jirevwe]

Hmm... I looked at the code before didn't understand much though.

Though I thought the problem would be from the loadMessages() function, but since you say it's working, cool... @takawww you can close the issue if you've solved the problem

[jirevwe]

@ibmshaikh create a new issue

[takawww]

Sure.. Thanks
