i need highlight/give feedback of row being touched user. how achieve it?

thanks in advance.

you need add android:focusable="true" in custom row item recyclerview

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="50dp"     android:id="@+id/drawer_row"     android:background="?android:selectableitembackground"     android:focusable="true"     android:clickable="true" > </relativelayout>
