android如何使用xmpp-smack在群聊中发送和接收图像和位置(使用地图)

Question

我使用android-xmpp开发群聊聊天应用程序,因为我不知道如何发送和重放图片图像或位置(使用地图).

所以任何一个人都可以请给我这样做的方法.

目前,我收到短信并添加到列表视图,如下所示,

Message msg = new Message(to, Message.Type.groupchat);
msg.setBody(text);
if (Constants.connection != null) {
    try {
        Constants.connection.sendPacket(msg);
        Log.d("Send to room  : Name : ", to);
        Log.d("store", "store data to db");
        //DBAdapter.addUserData(new UserData(text, "", "1" ,beam_id));
    } catch (Exception e) {
        Log.d("ooo", "msg exception" + e.getMessage());
    }

    messages.add(text);

    runOnUiThread(new Runnable() {
        public void run() {
           // set to listview
            setMyChatAdapter();
        }
    });
}

并使用StanzaTypeFilter接收.那么图像和位置共享如何？

我使用smack-extensions-4.1.3-sources.jar尝试使用FileTransferManager跟踪图像代码.

 private void sendImage()
 {

  FileTransferManager mg=new FileTransferManager(Constants.connection);
  OutgoingFileTransfer transfer = mg.createOutgoingFileTransfer(beam_id+"@"+Constants.conference_name + "/" + Constants.resources);
  File file = new File(selectedImagePath);
  try {
      transfer.sendFile(file, "test_file");
  } catch (Exception e) {
      e.printStackTrace();
  }
  while(!transfer.isDone()) {
      if(transfer.getStatus().equals(FileTransfer.Status.error)) {
          System.out.println("ERROR!!! " + transfer.getError());
      } else if (transfer.getStatus().equals(FileTransfer.Status.cancelled)
              || transfer.getStatus().equals(FileTransfer.Status.refused)) {
          System.out.println("Cancelled!!! "+ transfer.getError());
      }
      try {
          Thread.sleep(1000L);
      } catch (InterruptedException e) {
          e.printStackTrace();
      }
  }
  if(transfer.getStatus().equals(FileTransfer.Status.refused) || transfer.getStatus().equals(FileTransfer.Status.error)
          || transfer.getStatus().equals(FileTransfer.Status.cancelled)){
      System.out.println("refused cancelled error"+ transfer.getError());
   } else {
      System.out.println("Success");
   }
} 

但当我使用以下访问该文件时,

FileTransferManager mg = new FileTransferManager(Constants.connection);

它给我错误...有一个私人访问...所以,我发现该文件的构造函数是私有的,这是jar文件,所以我无法将其更改为公共.

那么,我怎样才能将该文件类访问到我的班级？

那么,我如何在聊天中共享(发送 - 接收)图像和位置信息？

请尽快帮助我.

提前致谢.

试试这个链接：参考

对于文件发送

FileTransferManager manager = new FileTransferManager(connection);
OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer('usre2@myHost/Smack');
File file = new File(filenameWithPath);
try {
   transfer.sendFile(file, 'test_file');
     } catch (XMPPException e) {
       e.printStackTrace();
}
while(!transfer.isDone()) {
   if(transfer.getStatus().equals(Status.error)) {
      System.out.println('ERROR!!! ' + transfer.getError());
   } else if (transfer.getStatus().equals(Status.cancelled)
                    || transfer.getStatus().equals(Status.refused)) {
      System.out.println('Cancelled!!! ' + transfer.getError());
   }
   try {
      Thread.sleep(1000L);
   } catch (InterruptedException e) {
      e.printStackTrace();
   }
}
if(transfer.getStatus().equals(Status.refused) || transfer.getStatus().equals(Status.error)
 || transfer.getStatus().equals(Status.cancelled)){
   System.out.println('refused cancelled error ' + transfer.getError());
} else {
   System.out.println('Success');
}

文件接收：

FileTransferManager manager = new FileTransferManager(connection);
manager.addFileTransferListener(new FileTransferListener() {
   public void fileTransferRequest(final FileTransferRequest request) {
      new Thread(){
         @Override
         public void run() {
            IncomingFileTransfer transfer = request.accept();
            File mf = Environment.getExternalStorageDirectory();
            File file = new File(mf.getAbsoluteFile()+'/DCIM/Camera/' + transfer.getFileName());
            try{
                transfer.recieveFile(file);
                while(!transfer.isDone()) {
                   try{
                      Thread.sleep(1000L);
                   }catch (Exception e) {
                      Log.e('', e.getMessage());
                   }
                   if(transfer.getStatus().equals(Status.error)) {
                      Log.e('ERROR!!! ', transfer.getError() + '');
                   }
                   if(transfer.getException() != null) {
                      transfer.getException().printStackTrace();
                   }
                }
             }catch (Exception e) {
                Log.e('', e.getMessage());
            }
         };
       }.start();
    }
 });
