Send data from custom MessageHolder to MessageActivity. #180

aalap03 · 2018-08-09T21:27:01Z

So I have a custom MessageHolder classes for both texts and Images, from which I make MessageHolders variable which goes to MessagesListAdapter.

From an action inside MessageHolderImage class, I need to call messageListAdapter.notifyDataSetChanged(), but as per the structure I dont have any use of MessageHolderImage class's constructor, please let me know how to approach this.

MessageActivity.class

messageHolders = MessageHolders()
            .setIncomingTextConfig(MessageHolderText::class.java, R.layout.other_user_message_item)
            .setOutcomingTextConfig(MessageHolderText::class.java, R.layout.my_user_message_item)
            .setIncomingImageConfig(MessagesHolderImage::class.java, R.layout.other_user_message_item_image)
            .setOutcomingImageConfig(MessagesHolderImage::class.java, R.layout.my_user_message_item_image)

messagesAdapter = MessagesListAdapter(pref.chatIdentity, messageHolders, ImageLoader { _, _ -> })

MessageHolderImage.class and MessageHolderText.class (Same classes except image and text difference ofcourse)

class MessagesHolderImage(itemView: View) : MessageHolders.BaseMessageViewHolder<MessageItem>(itemView), AnkoLogger{

    private var glide = Glide.with(itemView)
        .setDefaultRequestOptions(RequestOptions().placeholder(R.drawable.default))
    private val time: TextView = itemView.findViewById(R.id.user_message_time)
    private val name: TextView = itemView.findViewById(R.id.user_name)

    override fun onBind(messageItem: MessageItem?) {

        time.text = Utils.chatDateFormatterHour(messageItem?.createdAt.toString())
        name.text = messageItem?.user?.name

        if (messageItem?.user?.name?.contains(App.getPreferences().fname)!!)
            glideProfile.asBitmap()
                    .load(byteArray())
                    .into(profileImage)

       //how to go from here to messageActivity, as I dont have constructor which allows an 
       //interface callback which transfers data from here to messageActivity
    }
}

Please tell me if I have a wrong approach or something can be modified here, Thanks in advance.

Hi, Is there any ideas or help for this issue ????

bevzaanton · 2018-08-15T13:26:41Z

Hi @aalap03 , thanks for your request. It's very interesting question. Unfortunately you can't add callback to custom ViewHolder. I can't understand how we missed this functionality) In new version we will add this opportunity. I am working now on this task.

aalap03 · 2018-08-15T18:57:56Z

Thanks for the response and library work, will eagerly wait for the update.

bevzaanton · 2018-08-16T14:31:18Z

ChatKit version 0.3.1 has been released. You can check this documentation. If documentation is not clear, please let me know.

I tried and if I use the payload parameter in MessageHolderText constructor class, it crashes with error message

Somehow we couldn't create the ViewHolder for message. Please, report this issue on GitHub with full stacktrace in description.

(Posted stack trace at the very end here.)

Payload class with callback var

class Payload {
    lateinit var reactionCallBack: ReactionCallBack
}

Callback interface

interface ReactionCallBack {
     fun passReaction(reaction: Reaction)
}

CustomHolder class If I take payload parameter out, the error will go.

class MessageHolderText(itemView: View, var payload: Payload) : MessageHolders.BaseMessageViewHolder<MessageItem>(itemView, payload), AnkoLogger{
  
  override fun onBind(messageItem: MessageItem) {
      emojiAdapterMessage = EmojiAdapterMessage(itemView.context, reactions, payload)        
  }
}

And in my MessageActivity class I create MessageHolder like this

//creating the payload var.
val payload = Payload()
    payload.reactionCallBack = object : ReactionCallBack{
        override fun passReaction(reaction: Reaction) {
            updateOrSetAttributes(reaction.emoji)
        }
    }

//creating messageHolder and setting configs with Custom MessageHolderText 
messageHolders = MessageHolders()
            .setOutcomingTextConfig(MessageHolderText::class.java, R.layout.my_user_message_item, payload)
            .setIncomingTextConfig(MessageHolderText::class.java, R.layout.other_user_message_item, payload)
            .setOutcomingImageConfig(MessagesHolderImage::class.java, R.layout.my_user_message_item_image, payload)
            .setIncomingImageConfig(MessagesHolderImage::class.java, R.layout.other_user_message_item_image, payload)

This is the stacktrace I get when I enter the MessageActivity class.
Please let me know if my implementation is wrong somewhere ?

but iam already do "payload as Payload"
and after try...
this error cause
MessageHolders holdersConfig = new MessageHolders() .setIncomingTextConfig( CustomIncomingTextMessageViewHolder.class, R.layout.item_custom_incoming_text_message, payload) .setOutcomingTextConfig( CustomOutcomingTextMessageViewHolder.class, R.layout.item_custom_outcoming_text_message) .setIncomingImageConfig( CustomIncomingImageMessageViewHolder.class, R.layout.item_custom_incoming_image_message) .setOutcomingImageConfig( CustomOutcomingImageMessageViewHolder.class, R.layout.item_custom_outcoming_image_message);
but after change to this.
`val payload = CustomIncomingTextMessageViewHolder.Payload()
payload.avatarClickListener = object : CustomIncomingTextMessageViewHolder.OnAvatarClickListener {
override fun onAvatarClick() {
// updateOrSetAttributes(reaction.emoji)
toast("clicked")
}
}

    val holdersConfig = MessageHolders()
        .setIncomingTextConfig(CustomIncomingTextMessageViewHolder::class.java,R.layout.item_custom_incoming_text_message,payload)
        .setOutcomingTextConfig(CustomOutcomingTextMessageViewHolder::class.java,R.layout.item_custom_outcoming_text_message,payload)

        .setOutcomingImageConfig(CustomOutcomingImageMessageViewHolder::class.java,R.layout.item_custom_outcoming_image_message,payload)


    super.messagesListAdapter = MessagesListAdapter(SENDERID,holdersConfig,imageLoader)
    super.messagesListAdapter.enableSelectionMode(this)
    super.messagesListAdapter.setLoadMoreListener(this)
    super.messagesListAdapter.setDateHeadersFormatter(this)
    layout_messagelist.setAdapter(super.messagesListAdapter)`

no more error. thanks
