Callback

You can register and receive callbacks as shown below:

The tag value is a string value for registering or deleting channel events, and should be set to a unique string value.

TalkPlus.addChannelListener(tag, new TalkPlus.ChannelListener() {
    @Override
    public void onMemberAdded(TPChannel channel, List<TPUser> users) {
        // callback fired when new member is added to the channel

    }

    @Override
    public void onMemberLeft(TPChannel channel, List<TPUser> users) {
        // callback fired when member leaves the channel
    }

    @Override
    public void onMessageReceived(TPChannel channel, TPMessage message) {
        // callback fired when new message is received in the channel
    }
    
    @Override
    public void onMessageDeleted(TPChannel channel, TPMessage message) {
        // callback fired when message is deleted in the channel
    
    @Override
    public void onChannelAdded(TPChannel channel) {
        // callback fired when a new channel is created
    }
    
    @Override
    public void onChannelChanged(TPChannel channel) {
        // callback fired when the channel is updated
    }

    @Override
    public void onChannelRemoved(TPChannel channel) {
        // callback fired when the channel is deleted
    }
    @Override
    public void onMemberMuted(TPChannel channel) {
        // callback fired when member is muted
    }
    
    @Override
    public void onMemberUnMuted(TPChannel channel) {
        // callback fired when member is unmuted
    }
    
     @Override
    public void onMemberBanned(TPChannel channel) {
        // callback fired when member is banned
    }
    
    @Override
    public void onMemberUnBanned(TPChannel channel) {
        // callback fired when member is unbanned
    }
});

// remove channel listener
TalkPlus.removeChannelListener(tag);
