我想阻止我的聊天列表中选择一个特别的朋友与 XMPP 。 code正常工作。有没有例外，但我不能够阻止用户。 我使用明火服务器。我应该做在服务器上什么样的变化？

能否能跟大家有什么想法？

我的code：

 公共无效XMPPAddNewPrivacyList（连接的连接，用户名字符串）{

    字符串LISTNAME =newList;

    //创建PrivacyItem列表，将允许或
    //否认一些隐私方面

    名单＆LT; PrivacyItem＆GT; privacyItems =新矢量＆lt; PrivacyItem＆GT;（）;

    PrivacyItem项目=新PrivacyItem（PrivacyItem.Type.jid.toString（）
            假，1）;
    item.setValue（用户名）;
    privacyItems.add（项目）;

    //创建新的列表。

    尝试 {
        PrivacyListManager privacyManager =新PrivacyListManager（连接）;
        privacyManager = PrivacyListManager
                .getInstanceFor（连接）;
        privacyManager.createPrivacyList（LISTNAME，privacyItems）;

    }赶上（XMPPException E）{
        的System.out.println（PRIVACY_ERROR：+ E）;
    }
}
 

解决方案

试试这个...

 公共布尔blockFriend（字符串friendName）{

    PrivacyItem项目=新PrivacyItem（PrivacyItem.Type.jid，friendName，假，7）;
    PrivacyListManager privacyManager = PrivacyListManager.getInstanceFor（连接）;
    名单＆LT; PrivacyItem＆GT;名单=新的ArrayList＆LT; PrivacyItem＆GT;（）;
    list.add（项目）;

    尝试 {
        privacyManager.updatePrivacyList（NEWLIST，清单）;
        privacyManager.setActiveListName（NEWLIST）;
        返回true;
    }赶上（SmackException.NoResponseException | XMPPException.XMPPErrorException | SmackException.NotConnectedException E）{
        e.printStackTrace（）;
        返回false;
    }


}
 

和疏通 只是与真正的替代虚假privacyitem对象`

I want to block a particular friend from my chat list with XMPP. code works fine. There is no Exception, but I am not able to block a user. I'm using open fire server. what changes should i made on server?

Can u guys have any idea?

My code:

public void XMPPAddNewPrivacyList(Connection connection, String userName) {

    String listName = "newList";

    // Create the list of PrivacyItem that will allow or
    // deny some privacy aspect

    List<PrivacyItem> privacyItems = new Vector<PrivacyItem>();

    PrivacyItem item = new PrivacyItem(PrivacyItem.Type.jid.toString(),
            false, 1);
    item.setValue(userName);
    privacyItems.add(item);

    // Create the new list.

    try {
        PrivacyListManager privacyManager = new PrivacyListManager(connection);
        privacyManager = PrivacyListManager
                .getInstanceFor(connection);
        privacyManager.createPrivacyList(listName, privacyItems);

    } catch (XMPPException e) {
        System.out.println("PRIVACY_ERROR: " + e);
    }
}

try this ...

public boolean blockFriend(String friendName) {

    PrivacyItem item=new PrivacyItem(PrivacyItem.Type.jid,friendName, false, 7);
    PrivacyListManager privacyManager = PrivacyListManager.getInstanceFor(connection);
    List<PrivacyItem> list=new ArrayList<PrivacyItem>();
    list.add(item);

    try {
        privacyManager.updatePrivacyList(NEWLIST, list);
        privacyManager.setActiveListName(NEWLIST);
        return true;
    } catch (SmackException.NoResponseException |XMPPException.XMPPErrorException | SmackException.NotConnectedException e) {
        e.printStackTrace();
        return false;
    }


}

and for unblock just replace false with true in object of privacyitem `
