Modify Messages

After successfully sending an ultra group message, you can actively modify the content of the sent message.

Listen for Message Modifications by Remote Users

You can set up the setUltraGroupMessageChangeListener listener to monitor message modification operations by remote users. The application will receive notifications through the onUltraGroupMessageModified method. After a message is modified, Message#isHasChanged() will return true.

//Ultra group message change notifications
interface UltraGroupMessageChangeListener {
  //Message expansion updates or deletions
  void onUltraGroupMessageExpansionUpdated(List<Message> messages);
  //Message content changes
  void onUltraGroupMessageModified(List<Message> messages);
  //Message recalls
  void onUltraGroupMessageRecalled(List<Message> messages);
}

//Set ultra group message change listener
public void setUltraGroupMessageChangeListener(IRongCoreListener.UltraGroupMessageChangeListener listener)

Modify Sent Message Content for Local Users

After a local user successfully sends a message, the server returns the message's UID. To modify the message content, use modifyUltraGroupMessage by passing the Message UID of the message to be modified and the new message content. After modification, Message#isHasChanged() will return true.

tip

• The message type cannot be modified. If the original message is a text message, the new message content must be of type TextMessage.
• You cannot modify messages sent by others.

Sample Code

TextMessage newContent = TextMessage.obtain("Modified text message content");

ChannelClient.getInstance().modifyUltraGroupMessage(msgUid, newContent,

    new IRongCoreCallback.OperationCallback() {

    @Override
    public void onSuccess() { }

    @Override
    public void onError(IRongCoreEnum.CoreErrorCode ErrorCode) { }
});
