推荐答案

iq 头和命名空间、元素由 smack 自己处理或填充到 xml 中.下面给出了一个xml格式的IQ包及其扩展IQ包的实现.

The iq headers and the namespace,element are handled or filled in the xml by smack itself. A sample IQ packet in xml and its implementation by extending IQ packet are given below.

<iq to='[email protected]' id='khz0k-13678' type='get'><elementName xmlns='http://jabber.org/protocol/muc#something'><item affiliation="member"/></elementName></iq>

public class IQGetSomething extends IQ {
public static final String ELEMENT = "elementName";
public static final String NAMESPACE = "http://jabber.org/protocol/muc#something";
String memberType;

public IQGetSomething() {
    super(ELEMENT, NAMESPACE);
    setType(Type.get);
}

public String getMemberType() {
    return memberType;
}

public void setMemberType(String memberType) {
    this.memberType = memberType;
}


@Override
protected IQChildElementXmlStringBuilder getIQChildElementBuilder(IQChildElementXmlStringBuilder xml) {
    xml.rightAngleBracket();
    xml.append("<item affiliation=\"").escape(memberType).append("\"/>");
    return xml;
}
}
