Number of messages in thread
Hi. In my chat, messages may have other messages in their thread and I will display them on long clicking on the parent message. What I need is to show the number of messages in a thread on the main chat page. This could look like the number of unread messages in the chat list view, but I don't mind any simpler solution.

Hi, the library currently does not support threading beyond simple one already in your screenshot. A PR adding such support is welcome.
So it's not possible to add some extra TextView under message bubble, where I could write number off messages in thread?
You will need to create your own ViewHolder as well as extend the XML file with your custom widgets. Take a look at the docs and scroll near the bottom where the topic is discussed: https://github.com/hosannahighertech/MessageKit/blob/master/docs/message_list.md
Also check samples. They are very helpful!
