Android基於XMPP Smack Openfire下學習開發IM(二)對分組、好友和頭像等一些
下面就一塊兒來學習一下，如何查詢分組和添加分組等！java
1、查詢全部分組 經過Roster來獲取全部分組，Roster能夠經過connection.getRoster()來獲得。服務器
[java] view plaincopyprint? <SPAN style="WHITE-SPACE: pre"> </SPAN>/** * 獲取全部組 *
* @param roster * @return 全部組集合 */
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;
}ide
/**
* 獲取全部組
*
* @param roster
* @return 全部組集合
*/
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;
}
2、添加分組學習
也同樣經過roster來添加分組，groupName 爲分組名。.net
[java] view plaincopyprint? <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;
}
}code
/**
* 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;
}
}
3、查詢某個組裏面的全部好友 很簡單不解釋...orm
[java] view plaincopyprint? <SPAN style="WHITE-SPACE: pre"> </SPAN>/** * 獲取某個組裏面的全部好友 *
* @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;
}server
/**
* 獲取某個組裏面的全部好友
*
* @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;
}
4、查詢全部好友信息blog
很簡單rem
[java] view plaincopyprint? <SPAN style="WHITE-SPACE: pre"> </SPAN>/** * 獲取全部好友信息 *
* @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;
}
/**
* 獲取全部好友信息
*
* @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;
}
5、獲取用戶VCard信息
[java] view plaincopyprint? <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;
}
6、獲取用戶頭像信息
經過Vcard來獲取用戶頭像信息，能夠把 InputStream 轉換爲本身想要的類型，InputStream 轉Drawable
這篇文章裏能夠找到 http://blog.csdn.net/h7870181/article/details/8663760
[java] view plaincopyprint? <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);
}
7、添加好友（有、無分組）
[java] view plaincopyprint? <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;
}
}
8、刪除好友
[java] view plaincopyprint? <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;
}
}
9、查詢用戶
serverDoMain 爲服務器域名
[java] view plaincopyprint? <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必定非空，其餘兩個如果有設，必定非空
}
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必定非空，其餘兩個如果有設，必定非空
}
return results;
}
10、修改用戶頭像
[java] view plaincopyprint? <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);
