            privateChatManager.createDialog(sub_arr.get(position).getOccupentId(), new QBEntityCallbackImpl<QBDialog>() {
                @Override
                public void onSuccess(QBDialog dialog, Bundle args) {
                     Log.d("dialog1", dialog+"");
                }

                @Override
                public void onError(List<String> errors) {

                }
            });

Answer 1

如果你没有打电话

QBChatService.getInstance().login(qbUser);

然后下一行将返回null：

QBPrivateChatManager privateChatManager = QBChatService.getInstance().getPrivateChatManager();

所以正确的方法是登录聊天然后获取QBPrivateChatManager
