[FIXED] migrate LinearLayout to Cardview selectable

Issue

My recyclerview is:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:layout_width="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:background="@drawable/recyclerview_highlight"
    android:layout_margin="6dp">

    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="6dp">

        <TextView
            android:id="@+id/articleCategTextView"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:ellipsize="end"
            android:maxLines="1"
            android:text="@null"
            app:layout_constraintBottom_toTopOf="@id/articleNameTextView"
            app:layout_constraintRight_toLeftOf="@id/articleQteTextView"
            app:layout_constraintLeft_toLeftOf="parent"
            app:layout_constraintTop_toTopOf="parent" />

        <TextView
            android:id="@+id/articleQteTextView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            app:layout_constraintTop_toTopOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintLeft_toRightOf="@id/articleCategTextView"
            app:layout_constraintBottom_toTopOf="@id/articleNameTextView"
            android:text="@null" />

        <TextView
            android:id="@+id/articleNameTextView"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:ellipsize="end"
            android:maxLines="1"
            app:layout_constraintBottom_toBottomOf="parent"
            android:text="@null" />

    </androidx.constraintlayout.widget.ConstraintLayout>

</LinearLayout>

@drawable/recyclerview_highlight:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="true" android:drawable="@color/selected_color"/>
</selector>

In "onBindViewHolder", I highlight it, when selected with:

holder.itemView.setSelected(article.isSelected());

All is ok BUT, for a little more visual elegance, I wanted to transform the LinearLayout into Cardview. And when I try it, setSelected has not effect anymore. I even try to "setActivated" with state_activated but not better.

What should I modify to obtain the same type of operation? Is it at the level of the layout, the selector or the java code, and what to use instead of "selected"?

Solution

I finaly had to add a LinearLayout, inside the cardView; which is the one I setSelected() and the result is what I needed.
