问题:

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 `

I think that the problem should be one of the following:

• userName isn't correct, for example "[e-mail]".
• You are not listening for privacy changes I mean, you didn't implement the PrivacyListListener interface.
• In the PrivacyItem constructor don't you should use PrivacyRule.JID instead PrivacyItem.Type.jid.toString()?.
• If you wanna block a friend don't you should use updatePrivacyList instead createPrivacyList.

I reccomend you take a closer look to the documentation Smack documentation

    // Here function for block user on xmpp

    public boolean blockUser(String userName) {

    String jid = userName@localhost
    String listName = "public";

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

    //ArrayList privacyItems = new ArrayList();

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


    PrivacyItem item = new PrivacyItem(PrivacyItem.Type.jid, jid, false, 1);
    // item.setValue(userName);
    item.setFilterIQ(false);
    item.setFilterMessage(false);
    item.setFilterPresenceIn(false);
    item.setFilterPresenceOut(false);

    privacyItems.add(item);

    // Get the privacy manager for the current connection.

    // Create the new list.
    PrivacyListManager privacyManager = PrivacyListManager.getInstanceFor(XMPPUtils.INSTANCE.connection);


    try {
        privacyManager.updatePrivacyList(listName, privacyItems);
        privacyManager.setActiveListName(listName);

        return true;
    } catch (Exception e) {
        Log.e("PRIVACY_ERROR: ", " " + e.toString());
        e.printStackTrace();
    }

    return false;
}

Privacy is a method for users to block communications from particular other users. In XMPP this is done by managing one's privacy lists.

1 - In order to add a new list in the server, the client MAY implement something like:

 

    // Create a privacy manager for the current connection._
    PrivacyListManager privacyManager = PrivacyListManager.getInstanceFor(myConnection);
    // Retrieve server privacy lists_
    PrivacyList[] lists = privacyManager.getPrivacyLists();

2 - In order to add a new list in the server, the client MAY implement something like:

 


// Set the name of the list_
String listName = "newList";

// Create the list of PrivacyItem that will allow or deny some privacy aspect_
String user = "[e-mail]";
String groupName = "enemies";
ArrayList privacyItems = new ArrayList();

PrivacyItem item = new PrivacyItem(PrivacyItem.Type.jid, user, true, 1);
privacyItems.add(item);

item = new PrivacyItem(PrivacyItem.Type.subscription, PrivacyItem.SUBSCRIPTION_BOTH, true, 2);
privacyItems.add(item);

item = new PrivacyItem(PrivacyItem.Type.group, groupName, false, 3);
item.setFilterMessage(true);
privacyItems.add(item);

// Get the privacy manager for the current connection._
PrivacyListManager privacyManager = PrivacyListManager.getInstanceFor(myConnection);
// Create the new list._
privacyManager.createPrivacyList(listName, privacyItems);
