How to get bitmap from ViewGroup?

I'm using recycler view where each item is simple ImageView. My RecyclerView is places in a ViewGroup - FrameLayout.

My task is to get from my FrameLayout - a bitmap.

That is, I need to get a bitmap that will contain pictures that are visible on the screen. That is, I need to draw my recycler on the bitmap, but not the entire recycler, but only the part that is visible on the screen

For example:

Is it possible to implement this? Please help me.

This code works for me and is appropriate for your use case :

<?xml version="1.0" encoding="utf-8"?>
<layout 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">

    <data>

    </data>

    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context=".MainActivity">

        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/recyclerView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:padding="16dp"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent"
            app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager" />

    </androidx.constraintlayout.widget.ConstraintLayout>
</layout>

this is the code that gives visible items o recyclerView. It is very important to use rootView method

IntentUtils.prepareToShare(this,binding.recyclerView.rootView.drawToBitmap())

if you want to share your image use and see the result see this :
