android – 如何实现消息读取状态,如whatsapp蓝色刻度？

概述我正在开发一个应用程序,聊天是一个模块,聊天我正在使用xmpp.当我发送消息时,我使用DeliveryReceiptManager获取该消息传递状态. DeliveryReceiptManager.getInstanceFor(connection).enableAutoReceipts();DeliveryReceiptManager.getInstanceFor(connection).ad 我正在开发一个应用程序,聊天是一个模块,聊天我正在使用xmpp.当我发送消息时,我使用DeliveryReceiptManager获取该消息传递状态.

DeliveryReceiptManager.getInstanceFor(connection).enableautoReceipts();DeliveryReceiptManager.getInstanceFor(connection).addReceiptReceivedListener(new ReceiptReceivedListener(){        @OverrIDe        public voID onReceiptReceived(String arg0,String arg1,String arg2)        {            Log.v("app",arg0 + "," + arg1 + "," + arg2);        }});

但我需要表明该消息是用户READ或NOT whatsApp蓝色tickmark,
任何人都可以帮助我,我被击中了.如何实现此消息读取概念.

提前致谢.

@H_419_10@解决方法 创建自定义数据包扩展类

public class ReadReceipt implements PacketExtension{public static final String nameSPACE = "urn:xmpp:read";public static final String ELEMENT = "read";private String ID; /// original ID of the delivered messagepublic ReadReceipt(String ID){    this.ID = ID;}public String getID(){    return ID;}@OverrIDepublic String getElementname(){    return ELEMENT;}@OverrIDepublic String getnamespace(){    return nameSPACE;}@OverrIDepublic String toXML(){    return "<read xmlns='" + nameSPACE + "' ID='" + ID + "'/>";}public static class ProvIDer extends EmbeddedExtensionProvIDer{    @OverrIDe    protected PacketExtension createReturnExtension(String currentElement,String currentnamespace,Map<String,String> attributeMap,List<? extends PacketExtension> content)    {        return new ReadReceipt(attributeMap.get("ID"));    }}}

当进入聊天列表时发送具有相同包ID的消息标签

Message message = new Message(userJID);ReadReceipt read = new ReadReceipt(messagePacketID);message.addExtension(read);mConnection.sendPacket(sendReadStatus);

其中mConnection是xmmppConnection对象

将数据包扩展添加到消息对象

在连接到服务器之前,将此扩展提供程序添加到ProvIDerManager

ProvIDerManager.getInstance().addExtensionProvIDer(ReadReceipt.ELEMENT,ReadReceipt.nameSPACE,new ReadReceipt.ProvIDer());

创建packetListener类以从接收器接收读取收据

public class ReadReceiptManager implements PacketListener    {  private static Map<Connection,ReadReceiptManager> instances = Collections.synchronizedMap(new WeakHashMap<Connection,ReadReceiptManager>());    static     {        Connection.addConnectionCreationListener(new ConnectionCreationListener()         {            public voID connectionCreated(Connection connection)             {                getInstanceFor(connection);            }        });    }private Set<ReceiptReceivedListener> receiptReceivedListeners = Collections.synchronizedSet(new HashSet<ReceiptReceivedListener>());private ReadReceiptManager(Connection connection) {    ServicediscoveryManager sdm = ServicediscoveryManager.getInstanceFor(connection);    sdm.addFeature(ReadReceipt.nameSPACE);    instances.put(connection,this);    connection.addPacketListener(this,new PacketExtensionFilter(ReadReceipt.nameSPACE));} public static synchronized ReadReceiptManager getInstanceFor(Connection connection)  {    ReadReceiptManager receiptManager = instances.get(connection);    if (receiptManager == null)     {        receiptManager = new ReadReceiptManager(connection);    }    return receiptManager;}@OverrIDepublic voID processpacket(Packet packet) {    ReadReceipt dr = (ReadReceipt)packet.getExtension(ReadReceipt.ELEMENT,ReadReceipt.nameSPACE);    if (dr != null)     {        for (ReceiptReceivedListener l : receiptReceivedListeners)         {            l.onReceiptReceived(packet.getFrom(),packet.getTo(),dr.getID());        }    }}public voID addReadReceivedListener(ReceiptReceivedListener Listener) {    receiptReceivedListeners.add(Listener);}public voID removeRemoveReceivedListener(ReceiptReceivedListener Listener) {    receiptReceivedListeners.remove(Listener);  } }

最后添加监听器到你的xmpp连接对象,它成功地工作

ReadReceiptReceivedListener readListener = new ReadReceiptReceivedListener()                {                    @OverrIDe                    public voID onReceiptReceived(String fromJID,String toJID,String packetID)                     {                        Log.i("Read","Message Read Successfully");                    }                };                  ReadReceiptManager.getInstanceFor(connection).addReadReceivedListener(readListener);
