I am developing a comment section for my app. My goal is to create a way for users to reply to other comments and to be able to view and hide this comment list like on instagram:

instagram exemple

How can I create a replies list within an item in a RecyclerView? Also, how to show and hide the replies?

Thanks in advance!

You can try with below design

  • All comments are located inside a RecyclerView.
  • Each item is a vertical LinearLayout(1) including:
    • First layer content a TextView (used for comment)
    • Second layer content another vertical linear layout(2), including:
      • a text view: View more replies
      • a second layer is another vertical linear layout(3) again enter image description here

  • The third linear layout will contain replies, and will be show/hide on text view "view more replies" clicks. Newly added replies will be add to linear layout 3 by LinearLayout.addView() method.

  • Refresh recycler view items at resonable time by calling recycler view adapter notifyDataSetChanged() or similar methods.
