Why can't android:clickable="true" trigger a click event in the item layout of RecyclerView?
The original code is like this:

<TextView
        android:id="@+id/city_name"
        android:layout_width="match_parent"
        android:layout_height="70dp"
        android:background="?android:attr/selectableItemBackground"
        android:clickable="true"
        android:gravity="center_vertical"
        android:padding="16dp"
        android:text=" 新都市 "
        android:textColor="#666666"
        android:textSize="14sp"/>

I found that when clicking, there was only a ripple effect but the click event could not be triggered. Later, I changed android:clickable="true" to false, and the rest remained unchanged, but there was a ripple effect and a click event. Why is this?
