Answer 1

As I checked on your question images, your RecyclerView item layout has taken full height of screen for each item. The problem is you set Cardview's layout_ height to "match_parent", that's why it takes full height.

Here you need to changes is,

<androidx.cardview.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"> <!-- here you need to change wrap_content-->
