I am working on an app that have several recyclerView. When I use talkback to swipe between items, it does not specify item position out of items size such as 1 out of 12.

But I created a sample app and it said item position out of items size. So I wonder what may cause that talkback does not specify the position and size in RecyclerView.

Here is my sample that worked :

<?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">

    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">

        <TextView
            android:id="@+id/tv"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textColor="@color/colorAccent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintTop_toTopOf="parent"
            android:layout_margin="16dp"
            android:gravity="center"
            android:text="Hello"/>

        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/rv"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toBottomOf="@id/tv" />

    </androidx.constraintlayout.widget.ConstraintLayout>

</layout>

And here is list item adapter :

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android">

    <androidx.cardview.widget.CardView
        android:layout_width="125dp"
        android:layout_height="wrap_content"
        android:focusable="true"
        android:layout_margin="16dp">

        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:orientation="vertical">

            <TextView
                android:id="@+id/id_tag"
                android:textColor="@color/colorAccent"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_margin="16dp" />

            <TextView
                android:id="@+id/name"
                android:textColor="@color/colorAccent"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_margin="16dp" />

        </LinearLayout>

    </androidx.cardview.widget.CardView>

</layout>

Do you have any idea that why talkback may not say position and items size?
