How to expand space between RecyclerView Item while scrolling

Question

How to expand space between recyclerview item while scrolling as shown below. I tried to add a custom animation in onBindViewHolder method but this solution doesn't work as I want. It looks like some animation add to RecyclerView.OnScrollListener.onScrolled method. Any idea? Thx.

Answer 1

One thing we can do is hiding and showing a transparent view below ItemLayout onSrcoll

var scrollListener = object : OnScrollListener() {
            override fun onScrollStateChanged(recyclerView: RecyclerView, newState: Int) {
                super.onScrollStateChanged(recyclerView, newState)
                (list.adapter as CustomAdapter).changeState(newState)
            }
        }

and in Adapter

override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
        if(state == RecyclerView.SCROLL_STATE_IDLE){
            holder.view.visibility = View.GONE
        }else{
            holder.view.visibility = View.VISIBLE
        }
    }

    fun changeState(newState: Int) {
        state = newState
        notifyDataSetChanged()
    }
