ChatView send message not update in UI Thread

[tandinhlee]

My ChatView in a fragment (Single activity architect with navigation)
when send(message) called => UI not updated immediately (After user trigger a scroll action -> Message is added and displayed in view).

I just figure out that this issue happen when put ChatView inside constaintlayout view and have constraint size (fixed size is work normal)

When you using navigation graph: Your chat view not the root fragment -> Cause this issue
