android - AndroidのaSmack xmppでグループを作成するには?

Question

Androidでmucを作成しているときに、クラスキャスト例外が発生しています。

このコードを使用してマルチユーザーチャットルームを作成するだけです

MultiUserChat muc = new MultiUserChat(connection, "myFirstName@"+"you host/domain");

  // Create the room
  muc.create("testbot");

  // Get the the room's configuration form
  Form form = muc.getConfigurationForm();
  // Create a new form to submit based on the original form
  Form submitForm = form.createAnswerForm();
  // Add default answers to the form to submit
  for (Iterator fields = form.getFields(); fields.hasNext();) {
      FormField field = (FormField) fields.next();
      if (!FormField.TYPE_HIDDEN.equals(field.getType()) && field.getVariable() != null) {
          // Sets the default value as the answer
          submitForm.setDefaultAnswer(field.getVariable());
      }
  }
  // Sets the new owner of the room
  List owners = new ArrayList();
  owners.add("yourusername@"+"Your Host/Domain");
  submitForm.setAnswer("muc#roomconfig_roomowners", owners);
  // Send the completed form (with default values) to the server to configure the room
  muc.sendConfigurationForm(submitForm);

これでルームが作成され、その特定のルームにニックネームを持つ人を追加できます

このコードを使用してルームに参加します

// Create a MultiUserChat using a XMPPConnection for a room
      MultiUserChat muc2 = new MultiUserChat(connection, "myFirstName@conference."+"Your HOST/Domain");

  // User2 joins the new room
  // The room service will decide the amount of history to send
  muc2.join("testbot2");

これでルームが作成されて参加し、単純な 1 対 1 のチャットと同じようにグループチャットを開始できます

このコードを使用

ステップ:- 1. createMulti_User_Chat(); という関数を 1 つ作成します。

createMulti_User_Chat() 関数のコード

private void createMulti_User_Chat()
    {
        multiUserChat = new MultiUserChat(connection,room_name);
        try {

            multiUserChat.create("admin");

            Form form = multiUserChat.getConfigurationForm();
            Form submitForm = form.createAnswerForm();

            for (Iterator fields = form.getFields(); fields.hasNext();)
            {
                FormField field = (FormField) fields.next();

                if (!FormField.TYPE_HIDDEN.equals(field.getType()) && field.getVariable() != null)
                {
                    submitForm.setDefaultAnswer(field.getVariable());
                }

            }
            submitForm.setAnswer("muc#roomconfig_persistentroom", true);
            multiUserChat.sendConfigurationForm(submitForm);
            multiUserChat.join("admin");
            multiUserChat.invite(studio,"Join My Group");

        } catch (XMPPException e) {

            e.printStackTrace();
        }
    }

この関数で multiUserChat.invite(studio,"Join My Group"); メソッドでは、このグループに招待したい友達リストが必要です。

2. ログインを呼び出す前に、これを呼び出すだけですこのメソッドでログインする前に、プロバイダーマネージャーを手動で構成します
