一、查询所有分组
通过 Roster 来获取所有分组，Roster 可以通过 connection.getRoster() 来得到。
<span style="white-space:pre"> </span>/**
* 获取所有组
*
* @param roster
* @return 所有组集合
*/
public static List<RosterGroup> getGroups(Roster roster) {
List<RosterGroup> grouplist = new ArrayList<RosterGroup>();
Collection<RosterGroup> rosterGroup = roster.getGroups();
Iterator<RosterGroup> i = rosterGroup.iterator();
while (i.hasNext()) {
grouplist.add(i.next());
}
return grouplist;
}二、添加分组
也一样通过roster来添加分组，groupName 为分组名。
<span style="white-space:pre"> </span>/**
* 添加一个分组
*
* @param roster
* @param groupName
* @return
*/
public static boolean addGroup(Roster roster, String groupName) {
try {
roster.createGroup(groupName);
return true;
} catch (Exception e) {
e.printStackTrace();
return false;
}
}
三、查询某个组里面的所有好友
很简单不解释...
<span style="white-space:pre"> </span>/**
* 获取某个组里面的所有好友
*
* @param roster
* @param groupName
* 组名
* @return
*/
public static List<RosterEntry> getEntriesByGroup(Roster roster,
String groupName) {
List<RosterEntry> Entrieslist = new ArrayList<RosterEntry>();
RosterGroup rosterGroup = roster.getGroup(groupName);
Collection<RosterEntry> rosterEntry = rosterGroup.getEntries();
Iterator<RosterEntry> i = rosterEntry.iterator();
while (i.hasNext()) {
Entrieslist.add(i.next());
}
return Entrieslist;
}
四、查询所有好友信息
很简单
<span style="white-space:pre"> </span>/**
* 获取所有好友信息
*
* @param roster
* @return
*/
public static List<RosterEntry> getAllEntries(Roster roster) {
List<RosterEntry> Entrieslist = new ArrayList<RosterEntry>();
Collection<RosterEntry> rosterEntry = roster.getEntries();
Iterator<RosterEntry> i = rosterEntry.iterator();
while (i.hasNext()) {
Entrieslist.add(i.next());
}
return Entrieslist;
}
五、获取用户VCard信息
<span style="white-space:pre"> </span>/**
* 获取用户VCard信息
*
* @param connection
* @param user
* @return
* @throws XMPPException
*/
public static VCard getUserVCard(XMPPConnection connection, String user)
throws XMPPException {
VCard vcard = new VCard();
vcard.load(connection, user);
return vcard;
}
六、获取用户头像信息
通过Vcard来获取用户头像信息，可以把 InputStream 转换为自己想要的类型，InputStream 转Drawable
这篇文章里可以找到 http://blog.csdn.net/h7870181/article/details/8663760
<span style="white-space:pre"> </span>/**
* 获取用户头像信息
*
* @param connection
* @param user
* @return
*/
public static Drawable getUserImage(XMPPConnection connection, String user) {
ByteArrayInputStream bais = null;
try {
VCard vcard = new VCard();
// 加入这句代码，解决No VCard for
ProviderManager.getInstance().addIQProvider("vCard", "vcard-temp",
new org.jivesoftware.smackx.provider.VCardProvider());
vcard.load(connection, user+"@"+connection.getServiceName());
if (vcard == null || vcard.getAvatar() == null)
return null;
bais = new ByteArrayInputStream(vcard.getAvatar());
} catch (Exception e) {
e.printStackTrace();
}
if (bais == null)
return null;
return FormatTools.getInstance().InputStream2Drawable(bais);
} 七、添加好友（有、无分组）
<span style="white-space:pre"> </span>/**
* 添加好友 无分组
*
* @param roster
* @param userName
* @param name
* @return
*/
public static boolean addUser(Roster roster, String userName, String name) {
try {
roster.createEntry(userName, name, null);
return true;
} catch (Exception e) {
e.printStackTrace();
return false;
}
}
/**
* 添加好友 有分组
*
* @param roster
* @param userName
* @param name
* @param groupName
* @return
*/
public static boolean addUser(Roster roster, String userName, String name,
String groupName) {
try {
roster.createEntry(userName, name, new String[] { groupName });
return true;
} catch (Exception e) {
e.printStackTrace();
return false;
}
}
八、删除好友
<span style="white-space:pre"> </span>/**
* 删除好友
*
* @param roster
* @param userName
* @return
*/
public static boolean removeUser(Roster roster, String userName) {
try {
if (userName.contains("@")) {
userName = userName.split("@")[0];
}
RosterEntry entry = roster.getEntry(userName);
System.out.println("删除好友：" + userName);
System.out.println("User." + roster.getEntry(userName) == null);
roster.removeEntry(entry);
return true;
} catch (Exception e) {
e.printStackTrace();
return false;
}
} 九、查询用户
serverDoMain 为服务器域名
<span style="white-space:pre"> </span>/**
* 查询用户
*
* @param connection
* @param serverDomain
* @param userName
* @return
* @throws XMPPException
*/
public static List<User> searchUsers(XMPPConnection connection,
String serverDomain, String userName) throws XMPPException {
List<User> results = new ArrayList<User>();
System.out.println("查询开始..............." + connection.getHost()
+ connection.getServiceName());
UserSearchManager usm = new UserSearchManager(connection);
Form searchForm = usm.getSearchForm(serverDomain);
Form answerForm = searchForm.createAnswerForm();
answerForm.setAnswer("userAccount", true);
answerForm.setAnswer("userPhote", userName);
ReportedData data = usm.getSearchResults(answerForm, serverDomain);
Iterator<Row> it = data.getRows();
Row row = null;
User user = null;
while (it.hasNext()) {
user = new User();
row = it.next();
user.setUserAccount(row.getValues("userAccount").next().toString());
user.setUserPhote(row.getValues("userPhote").next().toString());
System.out.println(row.getValues("userAccount").next());
System.out.println(row.getValues("userPhote").next());
results.add(user);
// 若存在，则有返回,UserName一定非空，其他两个若是有设，一定非空
}
return results;
} 十、修改用户头像
<span style="white-space:pre"> </span>/**
* 修改用户头像
*
* @param connection
* @param f
* @throws XMPPException
* @throws IOException
*/
public static void changeImage(XMPPConnection connection, File f)
throws XMPPException, IOException {
VCard vcard = new VCard();
vcard.load(connection);
byte[] bytes;
bytes = getFileBytes(f);
String encodedImage = StringUtils.encodeBase64(bytes);
vcard.setAvatar(bytes, encodedImage);
vcard.setEncodedImage(encodedImage);
vcard.setField("PHOTO", "<TYPE>image/jpg</TYPE><BINVAL>" + encodedImage
+ "</BINVAL>", true);
ByteArrayInputStream bais = new ByteArrayInputStream(vcard.getAvatar());
FormatTools.getInstance().InputStream2Bitmap(bais);
vcard.save(connection);
