Android Question Cross platform chat layout audio messages

[DestroShark]

Hello everyone, I am developing a chat that should support audio messages. But I can't imagine how to implement them in this code (seekbar instead of text). I did not find anything similar on the forum, perhaps someone has already implemented such functionality or can help me with advice
Used this example: https://www.b4x.com/android/forum/threads/b4x-cross-platform-chat-layout-example.112649/#content

best regards
