QuickBlox检索聊天对话Android

Question

我正在使用QuickBlox构建一个Android Chat应用。当我想检索聊天对话框列表和用户列表时，它没有出现在我的屏幕上。我已经搜索了这个问题，发现我必须启用用户列表检索。所以我做到了，但是什么都没有改变...这是我的chatdialogslist代码：

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_chat_dialog);
        floatingActionButton = (FloatingActionButton) findViewById(R.id.fab);
        chatListDialogs = (ListView) findViewById(R.id.lstChatsDialog);
        createSessionForChat();
        loadAllChat();
        floatingActionButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(ChatDialogActivity.this,ListUsersActivity.class);
                startActivity(intent);

        });
    }
    private void loadAllChat() {
        QBRequestGetBuilder requestBuilder = new QBRequestGetBuilder();
        requestBuilder.setLimit(100);
        QBRestChatService.getChatDialogs(null,requestBuilder).performAsync(new QBEntityCallback<ArrayList<QBChatDialog>>() {
            @Override
            public void onSuccess(ArrayList<QBChatDialog> qbChatDialogs, Bundle bundle) {
                ChatDialogAdapter adapter = new ChatDialogAdapter(getBaseContext(),qbChatDialogs);
                chatListDialogs.setAdapter(adapter);
                adapter.notifyDataSetChanged();
            }
            @Override
            public void onError(QBResponseException e) {
              Log.e("ERROR",e.getMessage());
            }
        });
    }
    private void createSessionForChat() {
        final ProgressDialog mDialog = new ProgressDialog(ChatDialogActivity.this);
        mDialog.setTitle("Retreiveing The Dialogs");
        mDialog.setMessage("Please Wait While We Collecting your Chats Info.");
        mDialog.setCanceledOnTouchOutside(false);
        mDialog.show();
        String name,password;
        name = getIntent().getStringExtra("name");
        password = getIntent().getStringExtra("password");
         final QBUser qbUser = new QBUser(name,password);
        QBAuth.createSession(qbUser).performAsync(new QBEntityCallback<QBSession>() {
            @Override
            public void onSuccess(QBSession qbSession, Bundle bundle) {
                mDialog.dismiss();
                qbUser.setId(qbSession.getUserId());
                try {
                    qbUser.setPassword(BaseService.getBaseService().getToken());
                } catch (BaseServiceException e) {
                    e.printStackTrace();
                }
                QBChatService.getInstance().login(qbUser, new QBEntityCallback() {
                    @Override
                    public void onSuccess(Object o, Bundle bundle) {
                        mDialog.dismiss();
                    }
                    @Override
                    public void onError(QBResponseException e) {
                     Log.e("ERROR",e.getMessage());
                    }
                });
            }
            @Override
            public void onError(QBResponseException e) {
                Log.e("ERROR",e.getMessage());
            }
        });
    }
}

这是我的chatsdialogadapter代码：

            imageView.setImageDrawable(drawable);


        }

    }
}

在您的情况下，您调用异步方法创建foreSessionforchat（）和call call method loadallchat（），结果您可以在Session Creation同时开始加载对话框。成功创建QB会话后，您需要调用方法loadallchat（）。
