How to show part of next/previous card RecyclerView

I think the padding solution is not a good for all cases, because forces the last item to have padding to the right.

Personally i use runtime width calculation of each item and i am very satisfied with this. So you can do the following:

onBindViewHolder

if (position == data.size - 1) {
    holder.itemView.layoutParams = RecyclerView.LayoutParams(RecyclerView.LayoutParams.MATCH_PARENT, RecyclerView.LayoutParams.WRAP_CONTENT)
} else {
    if (width == null) {
        holder.itemView.viewTreeObserver.addOnGlobalLayoutListener(object : ViewTreeObserver.OnGlobalLayoutListener {
              override fun onGlobalLayout() {
                   holder.itemView.viewTreeObserver.removeOnGlobalLayoutListener(this)
                   width = holder.itemView.width
                   params.width = width!! - partOfPage
                   holder.itemView.requestLayout()
              }
         })
     } else {
         params.width = width!! - partOfPage
         holder.itemView.requestLayout()
     }
 }

The outcome is that all middle items are rendered showing a part of the next page, but the last one is rendered full width.

What you need to do is set padding to your RecyclerView, set clipToPadding to false, use a SnapHelper with it, and you need to make sure the margins on your cards are less than or equal to the padding in the RecylerView.

So, let's say you want the distance from the cards to the sides of the screen to be 16dp and you want the distance between the cards to be 8dp. You'll have to set the margins on each card to 4dp, so the total margin is 8dp. And you have to set the padding to 12dp, given there's already a margin of 4dp on each side of the card.

It'll look a bit like this:

Your list:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.RecyclerView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:layoutManager="android.support.v7.widget.LinearLayoutManager"
    android:clipToPadding="false"
    android:orientation="horizontal"
    android:paddingStart="12dp"
    android:paddingEnd="12dp"/>

Your cards:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginEnd="4dp"
    android:layout_marginStart="4dp"
    app:cardElevation="2dp"/>
