'How to make visible a element when the RecyclerView is loaded?
I'm making an social app and I want to implement a system where when you click on the comment button a Input dropdown...
The problem is that it doesn't matter what button you press, it always make visible the last "Publication" you did.

This is a photo where I clicked on the first comment button... Emulator img
Thank you in advance, I'm new here.
Solution 1:[1]
I fixed it!
The problem is using a binding in this case, so I replaced:
binding.multimediaInComment.setVisibility(View.VISIBLE)
for
Button multimediaInComment;
multimediaInComment = itemView.findViewById(R.id.multimediaInComment);
multimediaInComment.setVisibility(View.VISIBLE)
And now it's working :)
