Android基於XMPP Smack Openfire下學習開發IM對分組、好友和頭像等一些操作

一、查詢所有分組
通過Roster來獲取所有分組，Roster可以通過connection.getRoster()來得到。

[java]
<SPAN style="WHITE-SPACE: pre"> </SPAN>/**
     * 獲取所有組
     * 
     * @param roster
     * @return 所有組集合
     */ 
    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; 
    } 

 /**
  * 獲取所有組
  *
  * @param roster
  * @return 所有組集合
  */
 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、添加分組

也一樣通過roster來添加分組，groupName 為分組名。

[java]
SPAN style="WHITE-SPACE: pre"> </SPAN>/**
     * 添加一個分組
     * 
     * @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; 
        } 
    } 

 /**
  * 添加一個分組
  *
  * @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、查詢某個組裡面的所有好友
很簡單不解釋...

[java]
<SPAN style="WHITE-SPACE: pre"> </SPAN>/**
     * 獲取某個組裡面的所有好友
     * 
     * @param roster
     * @param groupName
     *            組名
     * @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; 
    } 

 /**
  * 獲取某個組裡面的所有好友
  *
  * @param roster
  * @param groupName
  *            組名
  * @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、查詢所有好友信息

很簡單

[java]
<SPAN style="WHITE-SPACE: pre"> </SPAN>/**
     * 獲取所有好友信息
     * 
     * @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; 
    } 

 /**
  * 獲取所有好友信息
  *
  * @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、獲取用戶VCard信息

[java]
<SPAN style="WHITE-SPACE: pre"> </SPAN>/**
     * 獲取用戶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; 
    } 

 /**
  * 獲取用戶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、獲取用戶頭像信息

通過Vcard來獲取用戶頭像信息，可以把 InputStream 轉換為自己想要的類型，InputStream 轉Drawable

 
[java]
<SPAN style="WHITE-SPACE: pre"> </SPAN>/**
     * 獲取用戶頭像信息
     * 
     * @param connection
     * @param user
     * @return
     */ 
    public static Drawable getUserImage(XMPPConnection connection, String user) { 
        ByteArrayInputStream bais = null; 
        try { 
            VCard vcard = new VCard(); 
            // 加入這句代碼，解決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); 
    } 

 /**
  * 獲取用戶頭像信息
  *
  * @param connection
  * @param user
  * @return
  */
 public static Drawable getUserImage(XMPPConnection connection, String user) {
  ByteArrayInputStream bais = null;
  try {
   VCard vcard = new VCard();
   // 加入這句代碼，解決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、無分組）

[java]
<SPAN style="WHITE-SPACE: pre"> </SPAN>/**
     * 添加好友 無分組
     * 
     * @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 有分組
     * 
     * @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; 
        } 
    } 

 /**
  * 添加好友 無分組
  *
  * @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 有分組
  *
  * @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、刪除好友

[java]
<SPAN style="WHITE-SPACE: pre"> </SPAN>/**
     * 刪除好友
     * 
     * @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("刪除好友：" + userName); 
            System.out.println("User." + roster.getEntry(userName) == null); 
            roster.removeEntry(entry); 
 
            return true; 
        } catch (Exception e) { 
            e.printStackTrace(); 
            return false; 
        } 
    } 

 /**
  * 刪除好友
  *
  * @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("刪除好友：" + userName);
   System.out.println("User." + roster.getEntry(userName) == null);
   roster.removeEntry(entry);

   return true;
  } catch (Exception e) {
   e.printStackTrace();
   return false;
  }
 }

九、查詢用戶

serverDoMain 為服務器名

[java]
SPAN style="WHITE-SPACE: pre"> </SPAN>/**
     * 查詢用戶
     * 
     * @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("查詢開始..............." + 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，則有返回,UserName一定非空，其他兩個若是有設，一定非空  
        } 
        return results; 
    } 

 /**
  * 查詢用戶
  *
  * @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("查詢開始..............." + 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，則有返回,UserName一定非空，其他兩個若是有設，一定非空
  }
  return results;
 }

十、修改用戶頭像

[java]
<SPAN style="WHITE-SPACE: pre"> </SPAN>/**
     * 修改用戶頭像
     * 
     * @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); 
    } 

 /**
  * 修改用戶頭像
  *
  * @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);

  FormatTools.getInstance().InputStream2Bitmap(bais);

  vcard.save(connection);
 }
