我正在为我的 android 应用程序使用 quickblox。我能够注册、登录用户，甚至添加自定义对象并从 quick-blox 服务器检索它们，但在聊天列表屏幕中我的计数出错了。

我遇到未读计数问题

这是我的代码流程:-

public class ConversationFragment extends Fragment implements Observer, DialogsManager.ManagingDialogsCallbacks {
    ConversationViewModel conversationViewModel;
    FragmentConversationBinding binding;
    QBChatDialogMessageListener allDialogsMessagesListener;
    SystemMessagesListener systemMessagesListener;
    QBSystemMessagesManager systemMessagesManager;
    QBIncomingMessagesManager incomingMessagesManager;
    private DialogsManager dialogsManager;

    public ConversationFragment() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        binding = DataBindingUtil.inflate(inflater, R.layout.fragment_conversation, container, false);
        getActivity().getWindow().setBackgroundDrawableResource(R.drawable.bg_img);
        View view = binding.getRoot();
        systemMessagesListener = new SystemMessagesListener();
        dialogsManager = new DialogsManager();

        return view;
    }

    private void setUpModel() {
        Bundle mBundle = getArguments();
        if (mBundle != null) {
            conversationViewModel = new ConversationViewModel(getActivity(), binding, getArguments().getString("DialogIdData"));
        } else {
            conversationViewModel = new ConversationViewModel(getActivity(), binding, "");
        }

        binding.setConversationViewModel(conversationViewModel);
        setUpObserver(conversationViewModel);

    }


    private void setUpObserver(ConversationViewModel observer) {
        observer.addObserver(this);
    }

    @Override
    public void update(Observable o, Object arg) {
    }

    @Override
    public void onDestroy() {
        super.onDestroy();

    }

    @Override
    public void onResume() {
        super.onResume();
        setUpModel();

    }

    @Override
    public void onPause() {
        super.onPause();
        unregisterQbChatListeners();
    }


    public void unregisterQbChatListeners() {
        if (incomingMessagesManager != null) {
            incomingMessagesManager.removeDialogMessageListrener(allDialogsMessagesListener);
        }

        if (systemMessagesManager != null) {
            systemMessagesManager.removeSystemMessageListener(systemMessagesListener);
        }
        dialogsManager.removeManagingDialogsCallbackListener(this);
    }

    @Override
    public void onDialogCreated(QBChatDialog chatDialog) {
    }

    @Override
    public void onDialogUpdated(String chatDialog) {

    }

    @Override
    public void onNewDialogLoaded(QBChatDialog chatDialog) {

    }

    private class SystemMessagesListener implements QBSystemMessageListener {
        @Override
        public void processMessage(final QBChatMessage qbChatMessage) {
            dialogsManager.onSystemMessageReceived(qbChatMessage);
        }

        @Override
        public void processError(QBChatException e, QBChatMessage qbChatMessage) {

        }
    }

    private BroadcastReceiver mNotificationReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {

    };


}

问题是当我进入聊天室并返回到我的聊天列表页面时，chatDialog.getUnreadMessageCount() 给我计数 2。

问题描述:-

例子:- 我已经在两台设备上安装了我的应用程序。当我从一个(设备 A)向另一个(设备 B)发送消息时。设备 B 将显示正确的未读计数，即 1 。现在，当我单击聊天对话框并进入(设备 B 的)聊天室时。然后返回到它的列表页面，然后再次尝试从设备 A 向设备 B 发送消息。这次未读计数为 2，但它应该是一个，因为我已经查看了我之前的消息。如果我尝试再次打开我的聊天室以阅读消息(设备 B)并在阅读消息后返回我的列表页面(设备 B)，情况会变得更糟。这一次，如果我从设备 A 向设备 B 发送消息，那么我的一条消息的计数结果为“5”，这让我感到恶心，我调试了整个代码，它是 chatDialog .getUnreadMessageCount() 回复我的人数“5”，我不知道为什么我以前的消息不计为已读消息以及为什么每次我打开聊天室都会在未读计数中添加一个额外的数字。请帮助我出来了，这两天我都在摸不着头脑。

非常感谢您的帮助。

谢谢

最佳答案

问题是您的 AllDialogsMessageListener 没有被注销，所以通过调用 unregisterQbChatListeners() 来注销它；当您打开聊天室屏幕时。一旦您这样做，一切都会正常进行。

这就是我的意思:-

binding.listDialogsChats.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                QBChatDialog selectedDialog = (QBChatDialog) parent.getItemAtPosition(position);
                if (currentActionMode == null) {
                    unregisterQbChatListeners();
                    ChatActivity.startForResult(((Activity) mContext), REQUEST_DIALOG_ID_FOR_UPDATE, selectedDialog);
                } else {
                    dialogsAdapter.toggleSelection(selectedDialog);
                }
            }
        });

private void unregisterQbChatListeners() {
        if (incomingMessagesManager != null) {
            incomingMessagesManager.removeDialogMessageListrener(allDialogsMessagesListener);
        }

        if (systemMessagesManager != null) {
            systemMessagesManager.removeSystemMessageListener(systemMessagesListener);
        }

        dialogsManager.removeManagingDialogsCallbackListener(this);
    }

干杯!!!
