Cannot collapsed header view programmatically

[khanguyen-appvity]

I want to hide the header view when I first open the application until I scroll down. However, it seems that there is no function that allows me to do it.
Thanks for any help!

Hello @khanguyen-appvity ,

maybe you can add a OnPreDrawListener when view is created and manually scroll the content so header is hidden
