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.
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 message
public ReadReceipt(String id)
{
this.id = id;
}
public String getId()
{
return id;
}
@Override
public String getElementName()
{
return ELEMENT;
}
@Override
public String getNamespace()
{
return NAMESPACE;
}
@Override
public 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;
}
@Override
public 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);
