问题 I am developing an application in which should have a vertical Recyclerview in which the items will be enlarged when touched by users and decreased when the user releases them. In my research I have not found a way to build it. The most similar to what I look for are the Facebook reactions as in the GIF below. How can I do it? Thanks in advance 回答1: Аll items are visible to user, there is no views to recycle. So IMHO RecyclerView here is redundant. I suggest you to use separate View s. As I

问题 From : https://developer.android.com/training/material/lists-cards.html I want to set RecyclerView in widget on home screen. Is it possible, and if it is, how to do it?

问题 I have RecyclerView and I set to each item OnTouchListener and OnClickListener OnTouchListener: override fun onBindViewHolder(holder: ItemListViewHolder, position: Int) { val item = getItem(position) holder.bind(item) holder.itemView.cardview.setOnTouchListener { v, event -> if (event.action == MotionEvent.ACTION_DOWN) { Log.d(TAG, "onBindViewHolder: $event.buttonState") this.startDragListener.onStartDrag(holder) } return@setOnTouchListener true } } OnClickListener: (inside the view holder)

问题 In one of my previous questions, I asked (and answered by myself following this blog post) how to properly handle key input on a RecyclerView . Now I realized that if I keep an arrow key pressed, let's say down key, the scrolling downwards stops and the RecyclerView loses its focus, probably because the scrolling is faster than the generation of all the children View s. Is there any workaround or better practice to properly handle hardware keyboard inputs on a RecyclerView ? Update: I
