我在聊天应用程序中使用了quickblox android sdk。我知道当对手用户启动会话时QBPrivateChatManagerListener - ＆gt; chatCreated（）事件被触发。以下是我的代码。当chatCreated被触发时，我加载了聊天片段。在聊天片段中，我实现了QBMessageListenerImpl接口。这里的问题是我没有从processMessage（）获得第一条消息。但我收到了第二条消息。所以我的问题是如何阅读对手用户发送的第一条消息？
@Override
public void chatCreated(final QBPrivateChat qbPrivateChat, boolean b) {
ShowMessage("Incoming chat!!");
if(!b)
{
runOnUiThread(new Runnable() {
@Override
public void run() {
CreateNewChatForIncoming(qbPrivateChat);
}
});
}
}
public void CreateNewChatForIncoming(QBPrivateChat qbPrivateChat) {
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
PrivateChatFragment privateChatFragment = new PrivateChatFragment();
privateChatFragment.setOpponentuser(null);
privateChatFragment.setIncomingChat(qbPrivateChat);
HashMap<Integer, QBUser> allusers = applicationSingleton.getAllusers();
String title = allusers.get(qbPrivateChat.getParticipant()).getFullName();
if (title != null)
this.setTitle(title);
ft.replace(R.id.content_frame, privateChatFragment);
ft.commit();
}

答案 0 :(得分：0)
尝试更改
privateChat = privateChatManager.getChat(opponentID);`enter code here` if (privateChat == null) {
privateChat = privateChatManager.createChat(opponentID, this);
}else{
privateChat.addMessageListener(this);
}
以
if (privateChat == null) {
privateChat = privateChatManager.createChat(opponentID, this);
}
privateChat.addMessageListener(this);
